Full textAbstract:
The selling of fruits and vegetables in the street is a common phenomenon in developing countries due to high levels of unemployment. In South Africa, street vending of fruits and vegetables brings valuable income to many impoverished households, thereby improving the livelihoods of people who are not formally employed. The Agricultural Product Standards Act No. 119 of 1990 of South Africa provides for the standardisation of quality norms for agricultural produce. Enforcing the Agricultural Product Standards Act is essential to ensure that agricultural produce sold in the streets is regulated and controlled so it is safe throughout the supply chain from the farm to the vending site. The purpose of this research was to investigate quality compliance of fresh fruits and vegetables sold by street vendors in the Tshwane metropolis, South Africa. A cross-sectional study survey was conducted in which stratified random sampling was used to sample 200 fresh fruit and vegetable vendors. Their knowledge of the requirements of the Agricultural Product Standards Act of South Africa was analysed. The compliance of their produce with quality regulations and the level of monitoring by authorities were also evaluated. Most respondents (89%) did not know about the Act. Only a small majority of fruit (51.5%) and vegetable (56%) retailers indicated that their agricultural products had been monitored. A large majority of fruits (86% to 99.8%) and vegetables (85.4% to 97.5%) met all the quality requirements in the Act. In general, a fair proportion of fruits (58%) and vegetables (65%) complied with the requirements of the Act. There was a significant positive correlation (p≤0.05) between monitoring by officials and the level of compliance. Only a small percentage of fresh fruits and vegetables vending sites are monitored by authorities. This paper is of interest to stakeholders in street vending of agricultural food produce because it raises awareness of areas of non-compliance and a need for effective compliance. Awareness and adequate enforcement can translate into selling and consuming agricultural high quality and safe food produce on the streets of Tshwane metropolis.

Full textAbstract:
In Vietnam, post-harvest losses of fruits and vegetables are very high. According to analysis reports, Vietnam must invest more in harvesting and post-harvest technologies to enhance the global competitiveness of agricultural products, including fruits and vegetables. Fruit harvesting machines are an effective solution to enhance the quality of agricultural products, including fruits and vegetables. The gripper can be considered the most important component of a harvesting machine when it comes to horticulture products, since it acts as interface between the robotic system and product. To pick up fruits, which frequently have complex shapes and poor mechanical properties, a gripper must be designed carefully. In addition to being able to pick the produce, it is crucial that a gripper does not damage the fruit during harvest. The weak force may cause the gripper to be unable to pick the fruit. If excessive force is applied or improper picking technique is used, the grippers could damage fruits. However, Vietnam has not widely adopted the use of automatic machine in agriculture. This is due to the uniqueness of fruits in each region; for example, fruits in Vietnam have their own shape and mechanical properties. Therefore, it is occasionally inappropriate to utilize harvesters that have already been imported. This paper shows the development and fabrication of a gripper for common Vietnam fruit grasping. A new prototype has been fabricated by 3D printing method and tested in the laboratory. The prototype of a gripper has been subjected to simulation and experimental testing with real fruits to verify that the proposed model is capable of meeting all objectives’ requirements. The proposed gripper was straightforward and efficient. The developed device exhibited dependability and stability and is suitable for farmers who require independent harvesting. In addition, the designed gripper can be produced at a lower cost than comparable machines developed by other commercial products. Key words: Harvesting machine, gripper, Solidwork, prototype, 3D printing, low-cost production

Full textAbstract:
Consumers always select and buy good quality fruits and vegetable. Selection criteria depend upon the freshness, shape, appearance, color, aroma and sturdiness at the first go. The taste and the shelf life come after that. As fruits play main role in day to day life, the grading of fruits is necessary in evaluating agricultural produce. The present existing technology are also used for fruit quality managing purpose but they are not more effective. There are some disadvantages like less reliability, less efficiency and less accuracy. In this paper, we would like to present a design and integration fruit quality classification solution for customer service. The purpose of this integration is to develop a service to classify the quality of fruits for customer in applications in agriculture, market or logistic.

The needs for added value of agricultural products is increasing, both in the form of health benefits and of reducing pollution waste. The sorting-out fruits that are just wasted can still be used as materials that have added value. In general, fruits contain glucose which is the basic ingredient in processing of bioethanol. Even though the quality has decreased, it still contains glucose which can then be fermented into bioethanol or organic fertilizer. Recently, the pharmaceutical and food and beverage industries require a large supply of bioethanol for further processing according to the industrial needs. Meanwhile, agricultural land is increasingly promoting organic farming. The objective of this activity is to produce new products from fruit waste into bioethanol and organic fertilizers that are useful for both the community and the government so that they can be used as the right solution to reduce environmental pollution and create new business opportunities. Bioethanol processing method uses Saccharomyces cerevisiae as a biocatalyst and uses an EM4 activator to produce organic fertilizers. This activity produces an output product in the form of bioethanol 46.78 % and organic fertilizer which contain 1% N.

Full textAbstract:
Nutrition and health are gaining significant focus as people seek convenient, nutrient-rich food options. Food processing must be efficient, cost-effective, and durable to meet these demands. Transforming fruits into diverse products using affordable technology can boost the economy for farmers and the nation. Fruit-based goods with high potassium and low salt offer substantial dietary benefits, making them valuable to health-conscious consumers.The present study aimed to study different value-added products from fruits and to increase their shelf life. Perishable fruit has losses during postharvest changes. Different strategies are required to avoid such losses. One method is to transform fruits into value-added goods. The transition of a raw resource or commodity into a processed product by combining raw materials, labour, time, and technology to produce a higher financial return is known as value addition in fruit processing. It focuses on ending hunger, achieving food security, improving nutrition, and promoting sustainable agriculture. Value-added fruit products can contribute to food security by achieving sustainable goals of good health and well-being. The study concluded that value-added fruit products play a vital role in the food industry, benefiting both producers and consumers. They reduce food waste, provide economic opportunities for farmers, and offer consumers convenient, nutritious, and flavourful options. The value-added fruit product market will likely further,contributing to the agricultural sector’s sustainability and worldwide consumer well being. This review details the value-added products in fruits.

Abstract Consumers increasingly address their attention to healthy fruits produced under organic agricultural managements. However, such produce may be less appealing in appearance influencing the purchase decisions of consumers. This research had the purpose to determine on three Italian local apple cultivars (Casciana, Rosa, Ruggine) the sensory appreciation of fruit through experiments conducted with blind (BC) and sighted (SC) consumers. The appreciation of apples differed between consumers with different visual ability. This aspect mainly concerned cvs Casciana and Rosa with contrasting fruit appearance traits. The BCs were inclined to better evaluate Casciana apples characterised by less attractive fruits. Conversely, the visual factor could have influenced the SCs’ judgment, as they appreciated Rosa more by the best outer traits of fruits. Intriguing responses were obtained when SCs were blindfolded.

Agriculture is the leading occupation for the people of the Jharkhand. State has potential to produce horticulture product and this type of product like fruits and vegetables need cold storage industry because It plays a significant role for the agricultural sector where various items such as Vegetables, fruits and meat etc.is stored where temperature is maintained, so as to protect them from getting spoiled and there by extend their preservation period with the help of precision instruments. Cold storages are an acute technology to keep perishable items safe.
It is also an industry to increase revenue by protecting and reducing the wastage of fruits & vegetables. Cold storage is a place where an item is needed can be taken anytime and can be made available to consumers very easily. Due to non-availability of space in the existing cold storage units, farmers are facing hardships to store their produced. The purpose of the study to analyze the current scenario of cold storage capacity in Jharkhand. It has been seen that there is a wide gap in availability of cold storages and agriculture produce to the markets. There are only 25 storage which has 80625MT capacity in Jharkhand. So, the urgent need for affordable, reliable, and sustainable expansion of cold storage infrastructure is crucial to boost agriculture's economic contribution. Farmers need the right financing and storage for the right price, enabling them to directly connect with multiple markets and maximize socio-economic impact.

Full textAbstract:
A Local fruit detection system is an agricultural vision field that can be implemented to increase the profit of a commodity. Besides that, North Sulawesi has a variety of local fruits which are widely used by people in their area and have a high selling value. The sorting system is an essential process of agricultural robots to sequentially separate fruit one by one. This automation process requires an accurate vision system to detect and separate fruit precisely and precisely. In addition, the implementation of a practical application demands a method to be able to work in real-time on low-cost devices. This work aims to design a local single fruit detection system for Sulawesi North by applying deep learning architecture to produce high performance. The architecture is designed to consist of an effective backbone for rapidly separating the distinctive features, an efficient attention module to improve feature extraction performance, and a classifier module employed to estimate the probabilities of each local fruit category. As a result, the designed model produces an accuracy value of 99,27% and 99,57% on the Fruits-360 and the local datasets, respectively. It outperforms other light architectures. In addition, deep learning models are designed to produce higher efficiency values than other competitors and can operate quickly at 100,488 Frames per Second.

Full textAbstract:
Grading fruits and vegetables has become essential for cross-border trade. There are various methods and technologies used for grading fruits and vegetables. In India, fruit growers mainly rely on manual grading, which is costly, labour-intensive, and affected by seasonal labour shortages. Manual grading is inefficient, inconsistent, and time-consuming. Grading of fruits and vegetables in ensuring the quality of produce and meeting consumer demands. The World Trade Organization (WTO) emphasizes high-quality graded products, prompting farmers to seek agricultural produce-grading machines for labour alleviation, time savings, and improved quality. Fruit grading enhances value, packaging, handling, and overall marketing. Typically, fruits are graded based on size, making them more desirable for export. Size-based grading methods include various types of graders. Weight grading is based on density and specific gravity. Market responsiveness necessitates improved grading and sorting practices to ensure quality assessment. Size variations in vegetables like potatoes and onions serve as the basis for categorization according to each country's market requirements.

Full textAbstract:
Vermicompost is an organic waste produced from earthworms that can enhance the soil condition and is rich with essential plant nutrients, thus increasing produce quality and shelf life. In this study, a one-year field trial was conducted to elucidate the effects of vermicompost supplementation on the composition of bioactive compounds and antioxidant activities of pineapple (Ananas comosus var. MD2) fruits, compared to control and application of chemical fertilizer. Based on the results, pineapple fruits produced from plants supplemented with chemical fertilizer showed the strongest radical scavenging properties against 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), followed by vermicompost and control plants. Application of chemical fertilizer and vermicompost also produced fruits with a very high content of chlorophylls and β-carotene compared to control plants. However, the amounts of bioactive compounds present in fruits produced with chemical fertilizer are higher than in fruits produced with vermicompost. Total phenolics content and Ferric Reducing Antioxidant Power (FRAP) reducing power were lowest in fruit extracts produced from pineapple plants supplemented with vermicompost. These results suggested that vermicompost cannot completely replace chemical fertilizer for the production of fruits with a high content of phytoconstituents but could be used as an additional supplement to reduce environmental pollution and ensure agricultural sustainability.

As organizações evoluíram desde o artesanato até as grandes corporações atuais, passando pela Revolução Industrial e Segunda Guerra Mundial. Essa evolução trouxe alterações expressivas na forma de administração, especialmente pelo surgimento do computador e pela globalização. As empresas tornaram-se obrigadas a captar as crescentes mudanças no ambiente e a substituir o empirismo e improvisação por uma administração baseada na tomada de decisão a partir da análise de dados, que foi facilitada pelo desenvolvimento de sistemas de informação. Na atividade agrícola, a utilização de sistemas de informação e adoção da gestão por processos, os quais permitem a gerência obtenção de melhores resultados no negócio ainda são incipientes. Assim, o objetivo do trabalho é a adaptação de um modelo voltado ao mapeamento de processos que permita a definição de indicadores para a avaliação de desempenho dos principais processos operacionais da produção citrícola. O sistema de produção foi mapeado a partir do modelo IDEF0 (Integrated Definition for Function Modelling), sendo dividido em quatro macroprocessos principais denominados A1 Plantio; A2 Tratos culturais I - estabelecimento das mudas; A3 Tratos culturais II - manutenção do pomar; A4 Colheita. As principais fases operacionais referentes a cada um dos macroprocessos foram definidas com base em um sistema de produção de uma empresa agrícola. Identificou-se 13 principais fases, que resultaram num total de 60 atividades e 248 indicadores operacionais, sendo que 28 indicadores foram classificados como relacionados ao sucesso das fases. Para os indicadores de produtividade, foi possível definir três classes: custo, tempo e quantidade, sendo \"tempo de manutenção das máquinas\", \"tempo de mão-de-obra utilizada\", e \"tempo de máquinas utilizado nas atividades\", os indicadores propostos de maior frequência para a avaliação do desempenho relacionado à utilização dos recursos. Os indicadores de qualidade relacionados ao sucesso com maior frequência nas fases foram os referentes à qualidade química do solo (ou substrato): saturação por bases, teores de macro e micronutrientes. A validação dos indicadores obtidos neste trabalho em uma empresa ou propriedade citrícola permitirá maior alcance para a utilização do modelo. Também a realização de novos trabalhos sobre indicadores de desempenho para a agricultura, como a análise do relacionamento causa-efeito entre estes, permitirá a definição de itens prioritários para a gestão do sistema produtivo.Organizations evolved from handicraft to the current large corporations, passing through the Industrial Revolution and World War II. This evolution has brought expressive changes in the management style, especially due to informatics and globalization. Companies were forced to adapt to the increasing changes in the business environment, as well as to replace the empiricism and improvisations by the management based on decision-making from data analysis, which was eased by the development of information systems. In agriculture, the use of information systems and the adoption of processes management, which provide better results, are still incipient. Therefore, this study aimed to adapt a model dedicated to process mapping, allowing indicators definition for the performance analysis of the main operational processes of the citrus production. The production system was mapped using the IDEF model, divided into four main macroprocesses named A1 Planting; A2 Cultural treatments I - seedling establishment; A3 Cultural treatments II - orchard maintenance; A4 Harvesting. The main operational stages of each macroprocess were defined based on the production system of an agricultural company. Thirteen main stages were identified, resulting in a total of 60 activities and 248 operational indicators, out of which 28 of them were linked to the success of the stages. Among the productivity indicators, it was possible to set those which belong to cost, time and quantity classes, being \"work time\", \"machinery time\" and \"maintenance time\", the more frequently proposed indicators for the performance evaluation related to resource use. The most frequently proposed quality indicators regarding the success of the stages were those related to the soil (or substratum) chemical quality: base saturation, macro and micronutrients levels. The validation of these indicators in a citrus company would expand the model application. The validation of these indicators in a citrus company will allow larger range for the model application. Also new studies about agricultural performance indicators, as the cause-effect analysis of them, will allow priority items to be defined to the production system management.

This study focuses on determining what key differences predispose a consumer to regularly purchase and be willing to pay a premium for sustainably-produced fruits and vegetables. Organic, local, and small farm are the three cases used in the study. The research used a structured questionnaire to conduct an online survey of U.S. internet users with email addresses in the spring of 2011 with logit and ordered logit regression used as the analytical tools. Cost was the most important factor for consumers who did not purchase organic and local products more frequently while unavailability was the principal reason for not consuming produces from small farms. The study showed consumers of small farm products often (98.5 percent of the time) consume local fruits and vegetables also but not the other way around. The relevant socio-economic factors for determining organic purchasing frequency were gender, household size, and education. For small farm they were the ability to influence local change and the respondents’ frequency of purchase of local products. Socio-economic characteristics did not prove to be a factor in local purchasing decisions. Regular purchasers of organic fruits and vegetables provided a consistent perception of organic products with the USDA certified organic definition. Local consumers reported that taste and freshness are the most defining characteristics of local products while small farm consumers could not provide a clear picture of the definitional statements defining fruits and vegetables produced by a small farm. This implied that there is need for more work by small farm producers to differentiate themselves in the market. On the contrary, both local and organic producers have a clear point of differentiation to reach their customers. Industry marketing efforts can be greatly improved by focusing on the characteristics of the consumers they are trying to reach. Our results can be further investigated by completing the following recommendations. First, to conduct more targeted studies such as interviews or focus groups, second, to gain a deeper understanding of how consumers perceive these attributes and third to conduct a comprehensive study on the similarities and differences between small farm and local consumers.

The demand for tropical fruit in the Czech Republic is rising, it´s a trend in the modern way of life. People in the Czech Republic, and all over the world, demand healthier ways of food consumption. We did research concerning a supply in the supermarkets and consumers. I found out, that a demand for tropical fruit was not very well covered and that people were demanding more variety of tropical fruit and were ready to up pay double prices for it. I compared data about consumption of tropical fruits in Germany, Austria and the Czech Republic. The comparison is drawn from net import of tropical fruit and net import it´s divided per capita. We proved that people in the Czech Republic were consuming fewer kilograms per capita per year than people in Germany and Austria. Annual consumption of tropical fruit in the Czech Republic grew by 7 % during the last five years, while in Germany it amounted to 0,3% and in Austria to 4,5%.

Full textAbstract:
fair trade is a business model approach that pretends to enhance the access to progress opportunities for rural populations through an empowering framework that supports small producers’ organizations and encourages investment decisions that improve welfare and sustainable development in their own communities. The values and practices underlying fair-trading emphasize a greater sensitivity on the conditions of small growers. The model integrates good agricultural practices, environmental stewardship, organizational transparency, empowerment, participative democracy, economic incentives and technology transfer in an alternative trade framework with the specific purpose of improving the income of rural producers of agricultural goods in developing countries. The most distinctive mechanism fair trade models use to improve the income of these producers is the direct payment of a minimum sales price to the farmer, which is at least equal to the market price. In exchange for this price security, the farmer commits to environmentally sound and socially responsible production practices. The main objective of this document is to provide a model for a handbook for small producers and organizations in Colombia interested in fair trade certification schemes. The paper collects relevant information for producers and organizations starting from an introduction of the fair trade system and the different labeling alternatives available in the market. It also provides general information about the background of the rural population in Colombia, useful for other audiences like researchers, and project leaders. In addition to explaining how the world’s leading fair trade labeling organization works and the procedure to obtain a certificate from them, the paper suggests screening and organizational-fitness tests intended to help interested producers and organizations to identify the suitability of the system to their own needs and detect internal strengths and weaknesses in relation to the specific certification requirements. The core of the document is a detailed analysis and compilation of the relevant compliance criteria producers and organizations must meet in order to become certificate holders and retain the certificate successfully. The standards set by the labeling body chosen for this work are paired to the compliance requirements of the respective auditing organization, local legal demands and practical guidance for compliance. The analysis is based on fair trade certification case studies, literature review and interviews with fair trade certified producers and experienced certification consultants in Colombia. Relevant local legislation and further informative documents for applicants are included in the Annexes. Its productive and demographic structure makes of fair trade schemes a relevant model for Colombia, a net producer and exporter of agricultural products. Production and trade patterns in Colombia, in combination with relentless land ownership concentration and inequality call for the implementation of alternative strategies with the potential of improving income in the short term; and strengthening capacity building, enhancing negotiation power of small farmers’ organizations and developing their skills for agro-business management in the long term.

Thesis (MBA)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Pierre du Plooy co-founded Prophyta (Pty) Ltd, a company that provided technical consultation services in the fields of horticulture and soil science to the South African deciduous fruit industry. Initially, the founders employed goods-dominant logic, viewing their services as intangible products that needed to be sold to clients. Between the founding of Prophyta in September 2012 and November 2014, Pierre du Plooy’s value proposition, service offering and revenue model diverged from those of other consultants in Prophyta, to the extent that he resigned from Prophyta and became an independent horticultural consultant. The study focussed on Pierre du Plooy’s existing clients. The clients were surveyed to determine their satisfaction with the current service offering, their interest in additional services, their openness toward alternative revenue models and key success factors according to them. A questionnaire was designed and 29 clients were invited to participate in the survey. Six responded, resulting in a response rate of 21 percent. Client satisfaction with the current service was measured using SERVQUAL. Fifteen statements applicable to the horticulture advisory service were made and respondents’ expectations and perceptions measured on a five point Likert scale. The values obtained for the expectation and corresponding perception per statement were used to calculate a difference score. A negative value for the difference score meant the perception of the current service exceeds client expectations regarding the statement in question. In general, the clients were satisfied with the current service offering. Two main aspects needed focus. A horticulturist needs to stay up-to-date with new research and technologies, requiring him to stay abreast of relevant literature, as well as attending symposia and production areas abroad. A horticulturist also has to be very attentive to keep classified information shared by clients confidential. The first aspect relates to the creation of new knowledge, the second to strengthening and building of relationships based on trust. According to the literature, both these aspects form the bases of competition and are very important in obtaining and maintaining a competitive advantage. It is recommended that Pierre du Plooy focus on above-mentioned aspects in order to maintain a sustainable competitive advantage over competitors. It is also recommended to repeat the client survey every two years in order to monitor changing client expectations and make sure client needs are being met.

Full textAbstract:
AbstractIndia’s transformation of its food system from a highly deficient one in the mid-1960s to one that is self-reliant and marginally surplus now is a success story that holds lessons for many smallholder economies in Africa and south and south-east Asia. India has emerged as the largest producer of milk, spices, cotton and pulses; the second largest producer of wheat, rice, fruits and vegetables; the third largest producer of eggs; and the fifth largest producer of poultry meat. It is also the largest exporter of rice, spices and bovine meat. All of this became possible with an infusion of new technologies, innovative institutional engineering, and the right incentives. However, as India looks towards 2030 and beyond, its food system faces many challenges ranging from increasing pressure on natural resources (soils, water, air, forests) to climate change to fragmenting land holdings, increasing urbanisation, and high rates of malnutrition amongst children. To meet these challenges successfully, India needs a proper mix of policies- from the subsidy-driven to the investment-driven, from price policy to income policy, promoting agricultural diversification towards more nutritious food. It also needs to incentivise its private sector to build efficient and inclusive value chains, giving due importance to environmental sustainability. More innovative technologies, from green-to-gene, increasing digitalisation, the Internet of Things, and artificial intelligence, would be needed to ‘produce more from less’ with a goal of feeding the most populous nation on this planet by 2030 in a sustainable manner.

AbstractIndia has come a long way from being a food scarce nation in the 1960s to a food surplus nation thereafter. The remarkable transformation of the agricultural sector was the result of massive improvements in productivity level owing to the Green Revolution in the case of cereals and the breakthrough that followed in few other agricultural commodities, most notably, dairying. Today, India is the largest producer of milk, pulses, banana, mango, pomegranate, papaya, lemon, okra, ginger and non-food crops like cotton and jute; the second-largest producer of rice, wheat, fruits and vegetables, tea and one of the leading producers of eggs and meat in the world. India produced 281.8 million tonnes of food grains, 307.7 million tonnes of horticulture crops, 176.5 million tonnes of milk, 96 billion eggs and 7.7 million tonnes of meat during TE 2018–19.

AbstractThe vulnerability of agriculture systems in Africa to climate change is directly and indirectly affecting the availability and diversity of plants and plant products available in local markets. In this chapter, markets in Benin City and environs were assessed to document the availability of plants and plant products. Markets were grouped into urban, suburban, and rural with each group having four markets. Majority of the plant and plant product vendors were women and 88 plant species belonging to 42 families were found. Their scientific and common names were documented as well as the parts of the plant and associated products available in the markets. Most of the plant and plant products found in local markets belong to major plant families. Urban markets had the highest diversity of plants and plant products. Three categories of plants and plant products were documented. Around 67% of the plants and plant products were categorized as whole plant/plant parts, 28% as processed plant parts, while 5% as reprocessed plant/plant parts. It was revealed that 86% of these plants are used as foods, 11% are for medicinal purposes, while 3% is used for other purposes. About 35% of plants and plant products across the markets were fruits, which is an indication that city and environs are a rich source of fruits. The local knowledge and practices associated with the plants and plant products can contribute towards formulating a strategic response for climate change impacts on agriculture, gender, poverty, food security, and plant diversity.

Full textAbstract:
After harvesting, fresh fruit’s quality cannot be improved but it can be maintained. Fruits should be harvested at the appropriate maturity stage and size. Harvesting of fruits at improper maturity stage reduces shelf-life. Time of harvest, method of harvest, tools used in harvesting also contribute to the wholesomeness of harvested fruits. Fruits are living organisms that continue their living processes after harvest; therefore, their handling directly affects freshness as well as optimum flavor. Maintaining cool temperatures, appropriate air combination to maintain the quality of fruits, producers, handlers, and retailers are to ensure that fruits going for processing, marketing, or into storage are at the best quality state. Indigenous handling refers to the native, age-long, cultural system of postharvest handling of horticultural crops. Postharvest handling comprises interconnected activities from harvest to sorting, grading, preservation, transportation, packaging, processing, marketing, and decision by the consumer to accept or reject the food. Improvement is the enhancement made on the traditional postharvest handling methods to reduce losses of agricultural produce by at least 5%. Various means have been developed over time to handle and preserve food and particularly fruits over ages of technology advancement from the Stone Age.

Full textAbstract:
Agriculture has managed to produce enough food for the accelerated population growth, which has led to environmental transformation and increasingly intensive exploitation of both renewable and non-renewable natural resources. The use of synthetic plant protection agents and fertilizers can lead to negative consequences in food production. Identification of agricultural food production systems is gaining importance in order to protect human health and the environment. Interest in the cultivation of certain plant species with an innovative approach to cultivation and technology has grown significantly. Organic and integrated agriculture implies the use of natural products while limiting or completely eliminating the use of synthetic resources. Knowledge of the mineral composition in tomato samples can be used as a potent tool in the identification of chemical markers as potential indicators of the farming system. The goal of the research is to determine the impact of different production systems on the content of macroelements in the fruits of different types of tomatoes.

Full textAbstract:
The agricultural sector has an important role in national economic development because of the abundant potential of natural resources and can support economic growth in rural areas. According to the Center for Agricultural Data and Information Systems, the Indonesian Ministry of Agriculture in 2020 stated that during the Covid-19 pandemic, the agricultural sector in Indonesia has proven to be a mainstay in stabilizing the country's economy. Until 2020, Bocek Village is the only village in Karangploso District, Malang Regency that does not yet have a Village-Owned Enterprises (VOE). With the Doctoral Service Program (Program Doktor Mengabdi), Bocek Village has established VOE in 2020. The DSP program in Bocek Village aims to create jobs and improve community welfare. The DSP program which is under the auspices of the Institute for Research and Community Service (IRCS) Universitas Brawijaya, is expected to be able to produce Leading Assisted Villages for the development of the agricultural and agro-industrial sectors in Bocek Village. The implementation of the DSP Program in Bocek Village has entered its 2nd year (2021) with a focus on strengthening the role of VOE in developing the community business sector. The team of DSP plans community service activities in the form of strengthening Bocek VOE in agricultural, agro-industry clusters and dissemination of technology and information. An alternative solution for the Bocek VOE business unit is to create a derivative product from citrus fruits, namely orange juice. The raw material for orange juice is the result of the process of sorting ripe oranges that have fallen to the ground. Marketing of citrus fruit juice products is planned by opening a Marketplace that can reach a wider target market. In addition, the potential for online sales can now be said to be more profitable than conventional because it has been supported by the rapidly growing digitalization transformation making online sales and marketing more profitable.

Full textAbstract:
Prior research conducted by our Institute has revealed the large quantities of food waste available in New York State, particularly in the Upstate corridor extending from Buffalo to Syracuse. The Finger Lakes region is heavily populated with agricultural operations, dairy farms and food processing plants, including those producing milk, yogurt, wine, and canned fruits and vegetables. The diverse supply of organic waste generated by these facilities offers the opportunity for sustainable energy production through one of three primary pathways: • Anaerobic digestion to produce methane • Fermentation to produce alcohols • Transesterification to produce biodiesel. Generally speaking, food wastes are better suited for biochemical conversion instead of thermo-chemical conversion (combustion, gasification, pyrolysis) due to their relatively high moisture content. The current paper provides an initial assessment of food wastes within the 9-County Finger Lakes region around Rochester, New York. Available databases were utilized to first identify all the relevant companies operating in one of four broad industry sectors: agriculture, food processing, food distribution and food services (including restaurants). Our analysis has demonstrated that anaerobic digestion can be a viable method for sustainable energy production from food waste in the Finger Lakes region, due to the dual economic benefits of effective disposal cost reduction and production of methane-rich biogas.

In 7th International Scientific Conference – EMAN 2023 – Economics and Management: How to Cope With Disrupted Times. Association of Economists and Managers of the Balkans, Belgrade, Serbia, 2023. http://dx.doi.org/10.31410/eman.2023.141.
Full textAbstract:
Agricultural production represents a significant financial and economic value of the Serbian economy. Today’s food crisis has shown the importance of agribusiness for the economic development of both, countries in transition and Serbia. Therefore, modern management approaches, in the sphere of agribusiness, are gaining more and more importance. A large number of agricultural enterprises in Serbia derive part of their value from the strength of the brand they produce. That is why agricultural managers strive to increase the value of the company, through increasing the value of the brand. As the modern economy bases value on the customer, it is important to look at and determine the parameters of the company’s value, through brand valuation. There are numerous examples of branded agricultural and food products in Serbia. These are traditional products, with a quality mark, made from high-quality domestic raw materials, according to a unique recipe and technological procedure. Such products usually have a mark of geographical origin and have recognizable characteristics. It adds value, that is realized, by selling on the market. In Serbia, the most common brands are the following products: meat, cheeses, wines, beers, water, honey and many other products obtained by processing domestic fruits and vegetables. Therefore, the goal of this paper is to determine the importance of the financial valuation of the brand in agribusiness in Serbia. In this paper, research was conducted based on data analysis through the synthesis of theoretical and empirical facts. From the methodological side, the work is based on the desk method of research, which covers synthesis, analysis, deduction and induction, but also methods of description of published scientific works, texts and documents related to brand valuation in agribusiness. In addition, the collected data were systematized. After the introduction, the paper primarily discussed the importance of product branding. The importance of the financial valuation of the brand in Serbia was analyzed with a focus on its financial effects, as well as the importance of product branding in Serbian agribusiness. At the end, a conclusion is given.

Full textAbstract:
The distribution chain is the path through which the product or service passes from the producer to the final consumer. This chain includes a number of stages and intermediaries that facilitate the movement, storage and sale of products or services. An effective distribution chain involves planning, accurate logistics and coordination between all participating intermediaries, to guarantee that the product or service reaches the consumer in good condition, at the right time and in the desired location. A well-organized distribution chain can help reduce costs, improve efficiency and increase consumer satisfaction. The Republic of Moldova is a country with fertile soils and a favorable climate for the development of agriculture, and fruits occupy a significant part of horticultural production. Although approx. half of the territory of the Republic of Moldova is dedicated to agriculture, which accounts for only 13% of the country's gross domestic product. Recently, efforts have been made to modernize and improve agricultural production technologies in order to improve the quality and yield of horticultural production in the Republic of Moldova, but farmers still encounter difficulties, especially at the stage of organizing the marketing chain of agricultural products. Due to blockages that occur in the distribution chain, products are delayed in reaching consumers, additional costs arise and damage to production occurs, which leads to losses, low yields, reduced profits and the efficiency of agricultural activities. In this article, we have proposed to analyze the distribution channels for the fruits produced in the Republic of Moldova, to identify the main blockages encountered during the distribution chain and to identify solutions for the efficiency and effectiveness of the distribution of Moldovan fruits both on the territory of the country and abroad.

Full textAbstract:
The most preferred method for preserving food or related products for a long time period is drying. In various countries of the world, the utilization of solar thermal systems in the field of agricultural for conserving fruits, vegetables, coffee and other related crops has revealed to be economical, practical, and environmental friendly. Solar heating systems to dry food and other crops can improve the quality of the product, while reducing wasted produce. This paper deals with development of solar cum eclectically operated food dryer. The fabrication of hybrid dryer is carried out which will be used for the drying process. The amounts of solar radiations are collected through transparent sheet or glass and they are entered in to dryer. Then, amount of heat will get generated in dryer and it will be circulated through fan in dryer itself which will be suitable for drying purpose. The experimentation is also carried out on two foods related to drying process at normal temperature and using this dryer obtained temperature. After experimentation it has been observed that there is difference in temperature at outside the dryer and inside the dryer. The temperature generated inside the dryer is sufficient for drying purpose. So, the developed food dryer can be used for drying the foods as per requirement.

Full textAbstract:
The current global developments that require an increase in efficiency, productivity, and sustainability are affecting fruit and berry growers. Without strategic initiatives at the governmental, non-governmental, and farm levels, the sector might fall behind in the global race for competitiveness. The goal of this study is to examine digitalization solutions in fruit and berry production and analyse whether and how they will impact the economic performance and competitiveness of Latvian farms working in this specific agricultural sector. To achieve this aim, both quantitative and qualitative research methods were applied, including theoretical analysis of digitalization solutions in agriculture, sectoral analysis, and gathering empirical data from Latvian fruit and berry producers, NGOs, researchers, and technology industry representatives. The results suggest that digitalization leads to increased efficiency and productivity, contributing to competitive advantage of Latvia’s agricultural holdings growing fruits and berries. However, numerous recommendations by stakeholders and the authors have been developed in order to accelerate the process.

The goal of this paper is to analyse socio-economic role of value added agriculture in Uzbekistan. The main agricultural exports are cotton (raw and yarn), fruits, vegetables, leather, wool and fur. There is an opportunity to acquire more social and economic advantages by exporting finished goods, which are made out of primary agricultural commodities. Adding value to agricultural products lead to increasing the share of finished goods in export, supplying import-substituting products, improving infrastructure in rural areas, providing new jobs and growing people’s income. The paper presents the analyse of the agriculture sector in GDP and the production dynamics of the primary agricultural commodities during 2005-2014, as well as comparison the share of cotton, fruits, vegetables and leather in export in 2005 and 2014. Based on the analyses it is recommended to widely use value added agriculture in order to support people, who are living in rural areas in Uzbekistan.

Full textAbstract:
Water is the source of life and is consumed mostly for agricultural purposes. Limited water is always a question in the Mediterranean region due to drought and climate change. Irrigation water requirement changes according to the crop pattern which is totally related to farmer decisions. Alanya is a town where tropical fruit cultivation area has increased dramatically as well as irrigation water requirements. Especially, bananas and avocados have become the most popular plants after citrus trees. The evapotranspiration of tropical fruits is higher than many other plants. For this reason, water becomes more valuable in the region due to limited water resources and irregular precipitation. In addition, rapid urbanization and tourism are the other big questions that cause the shift of agricultural areas to other areas, resulting in inadequate irrigation systems. Banana and avocado producers installed high technology of irrigation methods, such as drip and mini sprinkler systems. However, they do not measure the volume of irrigation water and still consume excessive water. In this study, social and technical precautions are taken by water authorities in the region for agricultural water management related to tropical fruit production. Data are obtained from the Agriculture Municipality and State Hydraulic Works and analysed by SWOT. As a result, the main findings are that irrigation water should be calculated, water volume should be measured at the farm level, and agricultural extension and consultancy should be increased for farmers’ education.

Fruit and vegetable identification and classification system is always necessary and advantageous for the agriculture business, the food processing sector, as well as the convenience shops and hypermarkets where these products are sold. Therefore, it is necessary to build an effective automated tool to meet the needs of the market by boosting the outcome, in order to improve economic efficiency. In this paper, a two-stage model is proposed to recognize fruits using camera images. Fruit disease recognition plays a crucial role in ensuring the quality and yield of fruits in agriculture. The framework for fruit disease recognition using a combination of VGG16 feature extraction, APGWO and CNN classification.VGG16 is a deep convolutional neural network known for its excellent feature extraction capabilities. APGWO adaptively adjusts the parameters to enhance the search efficiency and accuracy of feature selection. In this study, Adaptive particle – Grey Wolf Optimization (APGWO) has been applied for choosing the most pertinent features.

Full textAbstract:
The objectives of this project were to develop procedures and models, based on neural networks, for quality sorting of agricultural produce. Two research teams, one in Purdue University and the other in Israel, coordinated their research efforts on different aspects of each objective utilizing both melons and tomatoes as case studies. At Purdue: An expert system was developed to measure variances in human grading. Data were acquired from eight sensors: vision, two firmness sensors (destructive and nondestructive), chlorophyll from fluorescence, color sensor, electronic sniffer for odor detection, refractometer and a scale (mass). Data were analyzed and provided input for five classification models. Chlorophyll from fluorescence was found to give the best estimation for ripeness stage while the combination of machine vision and firmness from impact performed best for quality sorting. A new algorithm was developed to estimate and minimize training size for supervised classification. A new criteria was established to choose a training set such that a recurrent auto-associative memory neural network is stabilized. Moreover, this method provides for rapid and accurate updating of the classifier over growing seasons, production environments and cultivars. Different classification approaches (parametric and non-parametric) for grading were examined. Statistical methods were found to be as accurate as neural networks in grading. Classification models by voting did not enhance the classification significantly. A hybrid model that incorporated heuristic rules and either a numerical classifier or neural network was found to be superior in classification accuracy with half the required processing of solely the numerical classifier or neural network. In Israel: A multi-sensing approach utilizing non-destructive sensors was developed. Shape, color, stem identification, surface defects and bruises were measured using a color image processing system. Flavor parameters (sugar, acidity, volatiles) and ripeness were measured using a near-infrared system and an electronic sniffer. Mechanical properties were measured using three sensors: drop impact, resonance frequency and cyclic deformation. Classification algorithms for quality sorting of fruit based on multi-sensory data were developed and implemented. The algorithms included a dynamic artificial neural network, a back propagation neural network and multiple linear regression. Results indicated that classification based on multiple sensors may be applied in real-time sorting and can improve overall classification. Advanced image processing algorithms were developed for shape determination, bruise and stem identification and general color and color homogeneity. An unsupervised method was developed to extract necessary vision features. The primary advantage of the algorithms developed is their ability to learn to determine the visual quality of almost any fruit or vegetable with no need for specific modification and no a-priori knowledge. Moreover, since there is no assumption as to the type of blemish to be characterized, the algorithm is capable of distinguishing between stems and bruises. This enables sorting of fruit without knowing the fruits' orientation. A new algorithm for on-line clustering of data was developed. The algorithm's adaptability is designed to overcome some of the difficulties encountered when incrementally clustering sparse data and preserves information even with memory constraints. Large quantities of data (many images) of high dimensionality (due to multiple sensors) and new information arriving incrementally (a function of the temporal dynamics of any natural process) can now be processed. Furhermore, since the learning is done on-line, it can be implemented in real-time. The methodology developed was tested to determine external quality of tomatoes based on visual information. An improved model for color sorting which is stable and does not require recalibration for each season was developed for color determination. Excellent classification results were obtained for both color and firmness classification. Results indicted that maturity classification can be obtained using a drop-impact and a vision sensor in order to predict the storability and marketing of harvested fruits. In conclusion: We have been able to define quantitatively the critical parameters in the quality sorting and grading of both fresh market cantaloupes and tomatoes. We have been able to accomplish this using nondestructive measurements and in a manner consistent with expert human grading and in accordance with market acceptance. This research constructed and used large databases of both commodities, for comparative evaluation and optimization of expert system, statistical and/or neural network models. The models developed in this research were successfully tested, and should be applicable to a wide range of other fruits and vegetables. These findings are valuable for the development of on-line grading and sorting of agricultural produce through the incorporation of multiple measurement inputs that rapidly define quality in an automated manner, and in a manner consistent with the human graders and inspectors.

Full textAbstract:
The original proposal has three main objectives: a conceptual framework on willingness to pay (WTP) for fruits and vegetables, the introduction of branding and sampling in fresh food, and empirical applications to the United States and Israel. We modified our research plan over time based on availability of data and emergence of new problems. We expanded the range of products to include poultry and the range of techniques to use real experiments as well as more traditional surveys. We expanded the range of problems to understand attitudes toward genetically modified (GM) food. There is a growing interest in introduction of marketing tools like demonstration sampling, money-back guarantees, labeling, and brands in agriculture. These marketing tools are important for enhancing demand for agricultural products and food safety. However, the methodology needed to assess the effectiveness of these tools and understand their performance in different agricultural sectors is limited. Our analysis demonstrated the importance of brands as a marketing tool in agriculture. In particular, we showed conceptually that strong brands can be substitutes for other marketing tools like sampling or demonstration. We were able to conduct real experiments for the demand for safe chicken and show that consumers are willing to pay significantly more for products branded as more safe. Yet, using experiments in Israel and the United States, we found that WTP for brands of fresh fruits and vegetables is smaller than in other product categories. Warning labels are a sort of negative branding. The GM-free labeling is particularly important since it serves as a trade barrier to U.S. crops exports. Our analysis of acceptance of GM products found that WTP for GM products in Israel and the United States depends on framing of information about the impact ofGM and the quantity of information disclosed. Finally, in analyzing the evolution of support for Proposition 37 that aimed to introduce mandatory labeling of GM in California, we found that support for mandatory labeling ofGM products is broad as long as it is not perceived to be costly. Our project demonstrates the feasibility of conducting real experiments to assess consumer demand in agriculture. When looking at interdisciplinary groups, one can design new products and assess the WTP for their characteristics. We also show that, while branding is a very strong marketing tool, its use in fresh fruit and vegetables is likely to be limited. However, brands can be important with processed food. Furthermore, we have proven that, while some consumers strongly object to GM products, most consumers in the United States and Israel would be willing to buy them for a discount, and some would pay extra if they are associated with improved characteristics. Finally, we expanded the notion of warning labels to calorie information and showed that the response to calorie information depends on gender, education, and how the information is presented.

Full textAbstract:
Abstract The debate about whether to reduce import barriers on fresh produce in order to decrease the cost of living and increase welfare or to continue protecting the local agricultural sector by imposing import duties on fresh vegetables and fruits has been part of the Israeli and the US political dialog. The alternative of building a strong local brand that will direct patriotic feelings to support of the agricultural sector has been previously discussed in the literature as a non-tax barrier to global competition. The motivation of consumers to pay more for local fresh fruits and vegetables are better quality, environmental concerns, altruism, and ethnocentrism. Local patriotic feelings are expected to be stronger among national-religious consumers and weaker among secular left wing voters. This project empirically analyzes consumers’ attitude toward local agricultural production, perceptions of the contribution of the agricultural sector to society and how these perceptions interact with patriotic beliefs and socio-political variables perhaps producing an ethnocentric preference for fruits and vegetables. This patriotic feeling may be contrasted with feelings toward rival (or even politically opposing) countries competing in the same markets. Thus geo-political landscape may help shape the consumer’s preferences and willingness to purchase particular products. Our empirical analysis is based on two surveys, one conducted among Israeli shoppers and one conducted among US households. We find strong influences of nationalism, patriotism and ethnocentrism on demand for produce in both samples. In the case of Israel this manifests itself as a significant discount demanded for countries in conflict with Israel (e.g., Syria or Palestine), with the discount demanded being related to the strength of the conflict. Moreover, the effect is larger for those who are either more religious, or those who identify with right leaning political parties. The results from the US are strikingly similar. For some countries the perception of conflict is dependent on political views (e.g., Mexico), while for others there is a more agreement (e.g., Russia). Despite a substantially different religious and political landscape, both right leaning political views and religiosity play strong roles in demand for foreign produce.

Full textAbstract:
The main objectives of the research project were: 1. The manipulation, by genetic engineering techniques, of the terpenoid pathway in tomato fruit. Specifically, to test the hypothesis whether overexpression of linalool synthase in tomato fruits will result in the diversion of intermediates of the carotene biosynthetic pathway to linalool, demonstrating that linalool synthase is a key regulatory enzyme, and possibly improving tomato flavor. 2. The elucidation of the biochemical pathway leading to eugenol and methyl eugenol, and the manipulation of this pathway to determine key enzymes and to improve flavor in tomato. Background, conclusions and implications The different proportions of volatile components present in foods often determine their flavor properties. Two of the ten most important flavor compounds in tomatoes, linalool and eugenol, are emitted by the flowers of Clarkia breweri, (Onagraceae), a plant native to California, and are also present in sweet basil (Ocimum basilicum, Lamiaceae). We have studied the key enzymes and genes involved in the production of these flavorants. Linalool synthase, the key enzyme in linalool biosynthesis and its corresponding gene were isolated and characterized from Clarkia breweri. The gene was coupled to a fruit-specific tomato promotor (E8) and was used to transform tomatoes. The transgenic tomatoes produced S-linalool and 1-hydroxylinalool, compounds absent from the fruits of controls. The transgenesis did not adversely affect the overall appearance of the plants nor the levels of other terpenoids present such as carotenoids and vitamin E. Our work has proven that the terpenoid pathway in tomatoes can be modified by the introduction and expression of foreign genes coding for the enzymes controlling the production of monoterpenoid flavor compounds. We have also isolated novel enzymes and genes that are involved in the formation of eugenol and methyl eugenol from Clarkia breweri and basil. An EST library of basil glandular trichomes (the site of eugenol and methyl eugenol biosynthesis) was prepared. More than 1,200 genes have been preliminary characterized and a few of them have been confirmed by functional expression, to be involved in eugenol and methyl eugenol biosynthesis. These genes have augmented the still small repertoire of genes that are available to modify the aroma of agricultural produce by genetic engineering.

Lers, Amnon, Majid R. Foolad, and Haya Friedman. genetic basis for postharvest chilling tolerance in tomato fruit. United States Department of Agriculture, January 2014. http://dx.doi.org/10.32747/2014.7600014.bard.
Full textAbstract:
ABSTRACT Postharvest losses of fresh produce are estimated globally to be around 30%. Reducing these losses is considered a major solution to ensure global food security. Storage at low temperatures is an efficient practice to prolong postharvest performance of crops with minimal negative impact on produce quality or human health and the environment. However, many fresh produce commodities are susceptible to chilling temperatures, and the application of cold storage is limited as it would cause physiological chilling injury (CI) leading to reduced produce quality. Further, the primary CI becomes a preferred site for pathogens leading to decay and massive produce losses. Thus, chilling sensitive crops should be stored at higher minimal temperatures, which curtails their marketing life and in some cases necessitates the use of other storage strategies. Development of new knowledge about the biological basis for chilling tolerance in fruits and vegetables should allow development of both new varieties more tolerant to cold, and more efficient postharvest storage treatments and storage conditions. In order to improve the agricultural performance of modern crop varieties, including tomato, there is great potential in introgression of marker-defined genomic regions from wild species onto the background of elite breeding lines. To exploit this potential for improving tomato fruit chilling tolerance during postharvest storage, we have used in this research a recombinant inbred line (RIL) population derived from a cross between the red-fruited tomato wild species SolanumpimpinellifoliumL. accession LA2093 and an advanced Solanum lycopersicumL. tomato breeding line NCEBR-1, developed in the laboratory of the US co-PI. The original specific objectives were: 1) Screening of RIL population resulting from the cross NCEBR1 X LA2093 for fruit chilling response during postharvest storage and estimation of its heritability; 2) Perform a transcriptopmic and bioinformatics analysis for the two parental lines following exposure to chilling storage. During the course of the project, we learned that we could measure greater differences in chilling responses among specific RILs compared to that observed between the two parental lines, and thus we decided not to perform transcriptomic analysis and instead invest our efforts more on characterization of the RILs. Performing the transcriptomic analysis for several RILs, which significantly differ in their chilling tolerance/sensitivity, at a later stage could result with more significant insights. The RIL population, (172 lines), was used in field experiment in which fruits were examined for chilling sensitivity by determining CI severity. Following the field experiments, including 4 harvest days and CI measurements, two extreme tails of the response distribution, each consisting of 11 RILs exhibiting either high sensitivity or tolerance to chilling stress, were identified and were further examined for chilling response in greenhouse experiments. Across the RILs, we found significant (P < 0.01) correlation between field and greenhouse grown plants in fruit CI. Two groups of 5 RILs, whose fruits exhibited reproducible chilling tolerant/sensitive phenotypes in both field and greenhouse experiments, were selected for further analyses. Numerous genetic, physiological, biochemical and molecular variations were investigated in response to postharvest chilling stress in the selected RILs. We confirmed the differential response of the parental lines of the RIL population to chilling stress, and examined the extent of variation in the RIL population in response to chilling treatment. We determined parameters which would be useful for further characterization of chilling response in the RIL population. These included chlorophyll fluorescence Fv/Fm, water loss, total non-enzymatic potential of antioxidant activity, ascorbate and proline content, and expression of LeCBF1 gene, known to be associated with cold acclimation. These parameters could be used in continuation studies for the identification and genetic mapping of loci contributing to chilling tolerance in this population, and identifying genetic markers associated with chilling tolerance in tomato. Once genetic markers associated with chilling tolerance are identified, the trait could be transferred to different genetic background via marker-assisted selection (MAS) and breeding. The collaborative research established in this program has resulted in new information and insights in this area of research and the collaboration will be continued to obtain further insights into the genetic, molecular biology and physiology of postharvest chilling tolerance in tomato fruit. The US Co-PI, developed the RIL population that was used for screening and measurement of the relevant chilling stress responses and conducted statistical analyses of the data. Because we were not able to grow the RIL population under field conditions in two successive generations, we could not estimate heritability of response to chilling temperatures. However, we plan to continue the research, grow the RIL progeny in the field again, and determine heritability of chilling tolerance in a near future. The IS and US investigators interacted regularly and plan to continue and expand on this study, since combing the expertise of the Co-PI in genetics and breeding with that of the PI in postharvest physiology and molecular biology will have great impact on this line of research, given the significant findings of this one-year feasibility project.

Full textAbstract:
Fruits are vital to consumer diets and are an important part of the U.S. agricultural industry. Two berries--strawberries and blueberries--are among the most important fruits. With more than $2 billion in annual farm gate sales and accounting for a 13-percent share of total production value of fruit, strawberries rank third for all fruit produced in the United States. Blueberries account for 5 percent of total fruit production value. This report examined changes in domestic production, consumption, prices, and trade for strawberries and blueberries over two decades. This study helps understand how the major berry markets evolved in a short time and examined opportunities and challenges these markets face.--

Full textAbstract:
The objectives of this project were to develop nondestructive methods for detection of internal properties and firmness of fruits and vegetables. One method was based on a soft piezoelectric film transducer developed in the Technion, for analysis of fruit response to low-energy excitation. The second method was a dot-matrix piezoelectric transducer of North Carolina State University, developed for contact-pressure analysis of fruit during impact. Two research teams, one in Israel and the other in North Carolina, coordinated their research effort according to the specific objectives of the project, to develop and apply the two complementary methods for quality control of agricultural commodities. In Israel: An improved firmness testing system was developed and tested with tropical fruits. The new system included an instrumented fruit-bed of three flexible piezoelectric sensors and miniature electromagnetic hammers, which served as fruit support and low-energy excitation device, respectively. Resonant frequencies were detected for determination of firmness index. Two new acoustic parameters were developed for evaluation of fruit firmness and maturity: a dumping-ratio and a centeroid of the frequency response. Experiments were performed with avocado and mango fruits. The internal damping ratio, which may indicate fruit ripeness, increased monotonically with time, while resonant frequencies and firmness indices decreased with time. Fruit samples were tested daily by destructive penetration test. A fairy high correlation was found in tropical fruits between the penetration force and the new acoustic parameters; a lower correlation was found between this parameter and the conventional firmness index. Improved table-top firmness testing units, Firmalon, with data-logging system and on-line data analysis capacity have been built. The new device was used for the full-scale experiments in the next two years, ahead of the original program and BARD timetable. Close cooperation was initiated with local industry for development of both off-line and on-line sorting and quality control of more agricultural commodities. Firmalon units were produced and operated in major packaging houses in Israel, Belgium and Washington State, on mango and avocado, apples, pears, tomatoes, melons and some other fruits, to gain field experience with the new method. The accumulated experimental data from all these activities is still analyzed, to improve firmness sorting criteria and shelf-life predicting curves for the different fruits. The test program in commercial CA storage facilities in Washington State included seven apple varieties: Fuji, Braeburn, Gala, Granny Smith, Jonagold, Red Delicious, Golden Delicious, and D'Anjou pear variety. FI master-curves could be developed for the Braeburn, Gala, Granny Smith and Jonagold apples. These fruits showed a steady ripening process during the test period. Yet, more work should be conducted to reduce scattering of the data and to determine the confidence limits of the method. Nearly constant FI in Red Delicious and the fluctuations of FI in the Fuji apples should be re-examined. Three sets of experiment were performed with Flandria tomatoes. Despite the complex structure of the tomatoes, the acoustic method could be used for firmness evaluation and to follow the ripening evolution with time. Close agreement was achieved between the auction expert evaluation and that of the nondestructive acoustic test, where firmness index of 4.0 and more indicated grade-A tomatoes. More work is performed to refine the sorting algorithm and to develop a general ripening scale for automatic grading of tomatoes for the fresh fruit market. Galia melons were tested in Israel, in simulated export conditions. It was concluded that the Firmalon is capable of detecting the ripening of melons nondestructively, and sorted out the defective fruits from the export shipment. The cooperation with local industry resulted in development of automatic on-line prototype of the acoustic sensor, that may be incorporated with the export quality control system for melons. More interesting is the development of the remote firmness sensing method for sealed CA cool-rooms, where most of the full-year fruit yield in stored for off-season consumption. Hundreds of ripening monitor systems have been installed in major fruit storage facilities, and being evaluated now by the consumers. If successful, the new method may cause a major change in long-term fruit storage technology. More uses of the acoustic test method have been considered, for monitoring fruit maturity and harvest time, testing fruit samples or each individual fruit when entering the storage facilities, packaging house and auction, and in the supermarket. This approach may result in a full line of equipment for nondestructive quality control of fruits and vegetables, from the orchard or the greenhouse, through the entire sorting, grading and storage process, up to the consumer table. The developed technology offers a tool to determine the maturity of the fruits nondestructively by monitoring their acoustic response to mechanical impulse on the tree. A special device was built and preliminary tested in mango fruit. More development is needed to develop a portable, hand operated sensing method for this purpose. In North Carolina: Analysis method based on an Auto-Regressive (AR) model was developed for detecting the first resonance of fruit from their response to mechanical impulse. The algorithm included a routine that detects the first resonant frequency from as many sensors as possible. Experiments on Red Delicious apples were performed and their firmness was determined. The AR method allowed the detection of the first resonance. The method could be fast enough to be utilized in a real time sorting machine. Yet, further study is needed to look for improvement of the search algorithm of the methods. An impact contact-pressure measurement system and Neural Network (NN) identification method were developed to investigate the relationships between surface pressure distributions on selected fruits and their respective internal textural qualities. A piezoelectric dot-matrix pressure transducer was developed for the purpose of acquiring time-sampled pressure profiles during impact. The acquired data was transferred into a personal computer and accurate visualization of animated data were presented. Preliminary test with 10 apples has been performed. Measurement were made by the contact-pressure transducer in two different positions. Complementary measurements were made on the same apples by using the Firmalon and Magness Taylor (MT) testers. Three-layer neural network was designed. 2/3 of the contact-pressure data were used as training input data and corresponding MT data as training target data. The remaining data were used as NN checking data. Six samples randomly chosen from the ten measured samples and their corresponding Firmalon values were used as the NN training and target data, respectively. The remaining four samples' data were input to the NN. The NN results consistent with the Firmness Tester values. So, if more training data would be obtained, the output should be more accurate. In addition, the Firmness Tester values do not consistent with MT firmness tester values. The NN method developed in this study appears to be a useful tool to emulate the MT Firmness test results without destroying the apple samples. To get more accurate estimation of MT firmness a much larger training data set is required. When the larger sensitive area of the pressure sensor being developed in this project becomes available, the entire contact 'shape' will provide additional information and the neural network results would be more accurate. It has been shown that the impact information can be utilized in the determination of internal quality factors of fruit. Until now,

Full textAbstract:
Concepts for real-time grading of fruits and vegetables were developed, including multi-spectral imaging with structured illumination to detect and distinguish surface defects from concavities. Based on these concepts, a single-lane conveyor and inspection system were designed and evaluated. Image processing algorithms were developed to inspect and grade large quasi-spherical fruits (peaches and apples) and smaller dried fruits (dates). Adjusting defect pixel thresholds to achieve a 25% error rate on good apples, classification errors for bruise, crack, and cut classes were 51%, 42%, and 46%, respectively. Comparable results for bruise, scar, and cut peach clases were 48%, 22%, and 58%, respectively. Acquiring more than two images of each fruit and using more than six lines of structured illumination per fruit would reduce sorting errors. Doing so, potential sorting error rates for bruise, crack, and cut apple classes were estimated to be 38%, 38%, and 33%, respectively. Similarly, potential error rates for the bruitse, scar, and cut peach classes were 9%, 3%, and 30%, respectively. Date size classification results were good: 68% within one size class and 98% within two size classes. Date quality classification results were not adequate due to the problem of blistering. Improved features were discussed. The most significant contribution of this research was the on-going collaboration with producers and equipment manufacturers, and the resulting transfer of research ideas to expedite the commercial application of machine vision for postharvest inspection and grading of agricultural products.

Between 2007-09 and 2019-21, total U.S. agricultural imports increased at a compound annual growth rate of 5.6 percent (nominal value-i.e., not inflation-adjusted). Consumer-oriented products (such as beef, fruit, vegetables, and alcoholic beverages) became a more prominent part of this trade, with their share rising from 66.3 percent to 70.7 percent. These trends were even stronger when considering imports from Latin America and the Caribbean (LAC). To understand how and why U.S. agricultural imports from LAC changed, Economic Research Service economists used detailed trade statistics to explore the changing product and supplying-country composition of these imports

Full textAbstract:
Over the last few decades, the organic agriculture sector has experienced sustained growth. Globally, as well as in the European Union and Portugal, organic production accounts for just under 10% of total Utilised Agricultural Area (UAA) (FiBL, 2019; Eurostat, 2019; DGADR, 2019; INE, 2019; GPP, 2019). This growth has been seen in terms of production, number of producers, amount of retail sales, imports and exports. This article attempts to build on the multi-level perspective (MLP) of the socio-technical (ST) transitions theory by employing a whole systems analysis (Geels, 2018) of organic agriculture in Portugal, which defends an integrated vision of the systems, where multiple interactions occur within and among the niche, the regime and the landscape levels. This approach has been employed in order to develop a critical analysis of the current state of the Portuguese organic agriculture sector, stressing the multiplicity of elements that are contributing to the agro-food system´s transformation into a more sustainable one. In fact, the agro-food system is related with climate change but also has connections with other domains such as public health, water management, land use and biodiversity. Therefore, it is affected by shifts in these areas. This analysis considers developments in increasing domestic organic production, number of producers, amount of retail sales, imports, exports, market innovations, and the sector´s reconfiguration. The organic sector´s increase has been attributed to European regulation, institutionalization, standardization, farmer certification, external (government) subsidy support programs, incremental market improvements (visibility and product access), the emergence of new retailers, the rise of supporting consumers and a shift away from conventional agriculture (Truninger, 2010; DGADR, 2019; Pe´er et al, 2019). However, together with positive incentives, this sector also faces numerous barriers that are hindering a faster transformation. Difficulties for the sector to date have included: product placement; a disconnect between production, distribution and marketing systems; high transport costs; competition from imports; European subsidies focused on extensive crops (pastures, olive groves, and arable crops), entailing a substantial growth in the area of pasture to the detriment of other crops; the fact that the products that are in demand (fresh vegetables and fruit) are being neglected by Portuguese producers; expensive certification procedures; lack of adequate support and market expertise for national producers; the hybrid configuration of the sector; and price. Organic agriculture as a niche-innovation is still not greatly contributing to overall agricultural production. The low supply of organic products, despite its ever-increasing demand, suggests that a transition to increased organic production requires a deeper and faster food system reconfiguration, where an array of distinct policies are mobilized and a diversity of actions take place at different levels (Geels, 2018; Pe´er et al, 2019). This paper will attempt to contribute an overall critical assessment of the organic sector´s features and evolution and will identify some of the main obstacles to be overcome, in order to boost the sustainability transition of the agro-food system in Portugal.
