Abstract:

An increase in biofuel demand aligned with public policies has fueled the expansion of sugarcane into Goiás and Mato Grosso do Sul in the Cerrado. Geographic, temporal and physical asset specificities delimit the area from which mills can procure sugarcane, making sugarcane producers and mills dependent on each other. Thus contracting is a common practice in sugarcane production in the Cerrado and its success directly impacts the sustainability of the ethanol expansion. We fill a gap in the literature on producers’ contract acceptance and trust by determining the factors that affect contract perception and trust with contractors. Using primary data from the states of Goiás and Mato Grosso do Sul we estimate ordered logit models using producer’s perceptions, their characteristics and that of their enterprise. Profits and experience are important factors for a producer when considering a contract. Communication, transparency and other farmer’s perception of a mill were important in building trust. Mills wanting to improve their chances of signing a contract should focus on more participation in the community and on better communication with farmers.

Abstract:

Abstract Peruvian regions for sugarcane planting produce sugarcanes throughout the year with a high average productivity. The objective of this article is to analyze the role of agents in the sugarcane supply chain to Peruvian mills and their relationship with the practice of agrarian contracts to sugarcane production. The perception of landowners and farmers about bioenergy and their predisposition to plant energy crops is also investigated. Field interviews are conducted with the main agents of the sugarcane production chain in the major producing regions. Statistical analysis of data from field interviews indicates that the relationship between owners and sugarcane producers is of land leasing. Intermediate agents act as a fundamental part of the sugarcane supply chain. The sharecropping or sugarcane purchase contract is an instrument that is established between middlemen and small independent producers, whether they are owners or tenants. The middlemen participation in commercialization can reach 30–40% of the sugarcane production. Most mills prefer to produce sugarcane in own lands. A relatively high degree of inequity in favor of the middlemen appears in the intermediation process because, in general, the mills prefer this intermediation in their commercial practice. A large number of landowners and tenants are familiar with notions of energy crops, particularly in relation to sugarcane and have a positive vision about them for the environmental sustainability. However, their interest in planting bioenergy crops is less. Friendly and equitable relations between agents will provide more economic and social stability to the Peruvian sugarcane agroindustry.

Abstract:

The sugar and alcohol sectors are dynamic as a result of climate alterations, the introduction of sugarcane varieties, and new technologies. Despite these factors, Brazil stands out as the main producer of sugarcane worldwide, being responsible for 45% of the production of fuel ethanol. Several varieties of sugarcane have been developed in the past few years to improve features of the plant. This, however, led to the challenge of which variety producers should choose to plant on their property. In order to support this process, this research aims to test the application of the analytic hierarchy process (AHP) method to support producers to select which sugarcane variety to plant on their property. To achieve this goal, the research relied on a single case study performed on a rural property located inland of São Paulo state, the main producer state in Brazil. The results demonstrate the feasibility of the approach used, specifically owing to the adaptability capacity of the AHP method.

Abstract:

The diversity in agronomic practices being used by sugarcane producers in Brazil determines differences in economic performance and cost structure. The purpose of this study is to evaluate the cost of six systems of agronomic practices using fixed or variable rates for soil amendment, fertilizer, and defensive applications and assess the profitability of these systems at three scales of sugarcane production. We then describe the data sample related to the 2019–2020 harvest season and collected from fifty-five sugarcane producers in the central-south region of Brazil. Thereafter, using a quantitative approach, a cost analysis was performed, and the cumulative frequency of the net revenue for the three scales of production (small, medium, and large), was calculated using a Monte Carlo simulation. The cost analysis indicated that fertilizer had the highest cost considering the agronomic practices adopted at the three scales of production analyzed. The cumulative frequency analysis results from the Monte Carlo simulation showed the highest net revenue per hectare for medium sugarcane producers. In addition, the presence of economies of scale was not confirmed because the lowest cost was found in small-scale sugarcane producers and the highest net revenue was obtained by medium-scale sugarcane producers.

Abstract:

Many agroindustries that process sugarcane raw to produce sugar and ethanol, and for energy cogeneration have difficulties to obtain all the necessary raw material. The agrarian contract practice can allow access to land in order to increase the production of sugarcane, without immobilizing resources in terms of the purchase of land, reducing the idle capacity of industrial plant, and increasing the cogeneration of energy by burning bagasse and sugarcane straw. It appears that the form of production of sugarcane (i.e., through land leasing, sharecropping, independent producers, etc.) can significantly affect the total costs of the industrial process. This work looks to find an empirical relation between the type of sugarcane producers and the energy produced by the mill based on data of the Agricultural Census of Brazil and monitoring data of power plant operation parameters of a typical mill in Brazil. It was found that the sugarcane raw coming from lands worked for tenants and sharecroppers increased his participation 112% and 469% respectively in the energy generation in the period 2006 to 2017.

Abstract:

Abstract Population explosions of the stable fly (Stomoxys calcitrans) have become a serious concern for livestock producers near sugarcane mills in some regions of Brazil due to the insect’s massive reproduction on sugarcane byproducts and waste. Despite the limited efficiency of insecticides for controlling stable fly outbreaks, producers still rely on chemical control to mitigate the alarming infestations in affected areas. This study evaluated the susceptibility of S. calcitrans populations to cypermethrin in the state of Mato Grosso do Sul, Brazil. Stable flies were tested from three field populations and two colonies, established from flies previously collected at sugarcane mills. Wild flies were collected with Nzi traps in areas of sugarcane plantations. Both wild and colonized flies were exposed to eleven concentrations of cypermethrin in impregnated filter paper bioassays. All the populations proved to be resistant to cypermethrin, with resistance factors among field populations ranging from 6.8 to 38.6. The intensive use of insecticides has led to the development of pyrethroid resistance in stable fly populations in the proximities of sugarcane mills in the state of Mato Grosso do Sul.

Abstract:

The production of sweets and similar sugarcane products is an activity performed by smallholder farmers from Acorizal, Cuiabá, Jangada, Nossa Senhora do Livramento, and Santo Antônio do Leverger, in Mato Grosso. Therefore, this study aimed to assess the socioeconomic and productive aspects of rural producers (individuals and/or families) that work with the production of sweets and sugarcane derivatives in municipalities of the ‘Baixada Cuiabana’ region. 145 questionnaires were applied to rural producers in the period from March 2019 to January 2020. Among the main results, it was verified that the predominant profile is of rural producers with a low education level, with properties with a size smaller than a fiscal module (the size varies for each municipality), without DAP possession and/or access to sectorial public policies, such as PRONAF and ATER services. Furthermore, the main income source of the interviewees was the production of sweets and similar sugarcane-derived products, and the financial gain of most individuals was up to a minimum wage. Therefore, it is verified that the low education level and the absence of technical orientation might be conditioning for the permanence of farmers in situations of socioeconomic vulnerability.

Abstract:

The feasibility of integrating ethanol production into an existing sugar mill was analyzed by a stochastic spreadsheet model. As the price of corn continues to rise, ethanol producers will eventually need to look at other feedstock alternatives. Sugarcane has been proven to work well in the production of ethanol in Brazil. The results indicated existing U.S. sugar mills could economically switch to ethanol production. As imports into the United States threaten to undermine the U.S. sugar program, sugarcane producers have a viable alternative. At the very least, the alternative exists to diversify their income streams with ethanol production.

Abstract:

Plant diseases pose a major challenge in the agricultural sector, which affects plant development and crop productivity. Sugarcane farming is a highly organized part of farming. Owing to the desirable condition for sugarcane cultivation, India stands among the second largest producers of sugarcane over the globe. At the same time, sugarcane gets easily affected by multifarious diseases which significantly influence crop productivity. The recently developed computer vision (CV) and deep learning (DL) models with an effective design can be employed for the detection and classification of diseases in sugarcane plant. The disease detection in sugarcane plant is not accurate in the existing techniques. This paper presents a quantum behaved particle swarm optimization based deep transfer learning (QBPSO-DTL) model for sugarcane leaf disease detection and classification which produces high accuracy. The proposed QBPSO-DTL method is designed and trained for the prediction of diseased leaf images. The proposed QBPSO-DTL technique encompasses the design of optimal region growing segmentation to determine the affected regions in the leaf image. In addition, the SqueezeNet model is employed as a feature extractor and the deep stacked autoencoder (DSAE) model is applied as a classification model. Finally, the hyperparameter tuning of the DSAE model is carried out by using the QBPSO algorithm. For demonstrating the enhanced outcomes of the QBPSO-DTL approach, a wide range of experiments were implemented and the results ensured the improvements of the QBPSO-DTL model.

Abstract:

Sertãozinho-SP is a major world producer of sugarcane and peanuts. The crop rotation technique recovers soils and brings commercial benefits to producers. Objective: to determine the losses of water, nitrogen (N), phosphorus (P) and sediments, due to the use and occupation of the soil in the peanut and sugarcane crop, using the SWAT model, maintaining the topographic and physical attributes and climatic conditions of the Mogi-Guaçu River sub-watershed, in the Sertãozinho city – SP. To carry out this study, local data from digital elevation maps and soil pedological maps, precipitation, wind, solar radiation, and relative humidity were used. The actual accumulated evapotranspiration was higher in sugarcane (906.7 mm) when compared to peanuts (886.1 mm). Sediment losses were higher in peanuts (300.66 mm) when compared to sugarcane (280.69 mm), as well as losses of N (118.44 and 34.48 kg ha-1) and P (5.456 and 0.805 kg ha-1), respectively. It is concluded that the peanut crop showed the greatest losses of water, nutrients, and sediments, when compared to sugarcane, showing that the land cover directly influenced these losses. Studies like these can aid in decision-making about environmental policies, helping with soil and water conservation in Brazilian sub-watershed.

Abstract:

El cultivo de caña de azúcar forma parte de una tradición agrícola establecida en la época colonial. Es ese tiempo la hacienda se encargaba de organizar su producción. Esto ha ido cambiando. Con el movimiento revolucionario se resquebrajó la estructura hacendaria y surgieron nuevos actores en el campo, llamados ejidatarios. Al mismo tiempo se establecieron decretos encaminados a proteger los complejos industriales para que los ejidatarios aledaños al ingenio continuaran con su producción. Ante este panorama es importante analizar la forma en la que los productores se han ido articulando y las relaciones de poder que se generan en este proceso mediante la intervención de las asociaciones locales de productores. SUGARCANE PRODUCER ORGANIZATIONS AND THEIR POWER RELATIONS: THE CASE OF THE CASASANO LOCAL SUGARCANE FARMERS ASSOCIATION IN CUAUTLA DE MORELOS, MEXICO Sugarcane cultivation is part of an agricultural tradition established during the colonial period. During that time, sugarcane production was organized by large land holdings known as haciendas. This has changed. With the revolutionary movement, this landed estate structure crumbled and rural areas experienced the emergence of new communal landholders, known as ejidatarios. At the same time, laws aimed at protecting industrial complexes were decreed enabling the communal landholders adjacent to sugar refineries to continue with production. Within this scenario, it is important to analyze the way in which producers have been articulating as well as the power relationships generated through this process via the intervention of local producer associations.

Abstract:

Outbreaks of stable fly, Stomoxys calcitrans, cause losses for livestock producers located near sugarcane mills in Brazil, especially in southern Mato Grosso do Sul. The sugarcane mills are often pointed by local farmers as the primary source of these outbreaks; some mills also joined the farmers in combating the flies. Brazilian beef cattle production has great economic importance in similar level to bio-fuel production as ethanol. In this context, the wide-ranging knowledge on the biology and ecology of the stable fly, including larval habitats and their reproduction sites is extremely important for further development of control programs. This paper aims to report the occurrence and development of S. calcitrans larvae inside sugarcane stems in three municipalities of Mato Grosso do Sul. The sugarcane stems give protection against bad weather conditions and insecticide application. In this way, for sustainable sugarcane growth specific research concerning this situation should be conducted.

Abstract:

AbstractOrthodox approaches to development view the market as a key institution for driving economic transformation and for fostering innovation and competitiveness. The working of markets alone, however, does not always lead to improved outcomes such as increase in productivity or production efficiency in the context of smallholders. The role of non-market institutions, therefore, remains important. This paper examines the role of intermediary coordination in addressing constraints to efficiency and productivity of smallholder sugarcane producers in Tanzania. It also makes a contrastive analysis of a different organisational arrangement for smallholder sugarcane producers in Malawi. The key proposition is that while intermediary organisations of cane outgrowers in Tanzania have played a significant role in promoting effective market linkage, an increase in productivity required for competitiveness is limited by the lack of effective horizontal coordination.

Abstract:

Peanut cultivation has been used as a rotation crop in sugarcane renewal areas in São Paulo, state, Brazil. This practice guarantees agronomic and economic benefits to the region in a way complementary to the sugarcane crop. Small- and medium-sized rural producers have specialized in the cultivation of peanuts in the of renewal sugarcane areas, with production mainly occurring via a lease contract system. Thus, the objective of this study is to analyze the economic viability of commercial and productive operations associated with the peanut cultivation in leased areas. From a delimitated production profile modal, it was possible to analyze economic viability by triangulating secondary and primary information for peanut cultivation in Jaboticabal, the city of greatest production of this oil-giving seed in Brazil. Using Net Present Value, Internal Rate of Return, Return on Investment and Point of Equilibrium techniques, it was possible to show that the peanut crop is operationally feasible. However, financial and economic viability only occurred when leases cost equal or less than 50 sacks per hectare and when the producer was able to work with an area equal to or greater than 91 hectares (the break-even point). These results bring new economic information, supplementing that already in literature and provides data necessary for the rural producer to plan of production and size of investment.

An efficient system is now in place for improving diverse sugarcane cultivars by genetic transformation, that is, the insertion of useful new genes into single cells followed by the regeneration of genetically modified (transgenic) plants. The method has already been used to Introduce genes for resistance to several major diseases, Insect pests and a herbicide. Field testing has begun, and research is underway to identify other genes for increased environmental stress resistance, agronomic efficiency and yield of sucrose or other valuable products. Experience In other crops has shown that genetically Improved varieties which provide genuine environmental and consumer benefits are welcomed by producers and consumers. Substantial research Is still needed, but these new gene technologies will reshape the sugar industry and determine the International competitive efficiency of producers.

Abstract:

The present research empirically determined the factors influencing total factor productivity (TFP) of sugarcane producers in the Kwara State of Nigeria. Data were obtained from using the 2017-2018 sugarcane cropping season field survey through the administration of a structured questionnaire complemented with an interview schedule on 105 sugarcane farmers selected via multi-stage sampling technique. The collected data were analyzed using the conventional TFP index and censored regression model. From the empirical findings, it was observed that inefficiency in the allocation of working capitals, capital consumption, and health-related challenges decreased the TFP of sugarcane farmers in the studied area. However, the study advised the extension agents to educate farmers to be rational in resource allocation in order to optimize their productivity in sugarcane production. In addition, the study advised farmers to adopt health precautious measures in order not to predispose their family members to tropical diseases and should imbibe savings and investment cultures

Abstract:

Sugarcane (Saccharum Offcinarum L) is one of the important commodities for making sugar which has become a necessity for industry and households. Sugarcane which is processed into sugar granules or often known as brown sugar is located in the Ketol District, Central Aceh Regency. Central Aceh Regency, especially in Ketol District, West Blang Mancung Village, is one of the sugar cane producers. Sugarcane is an annual plant that has its own characteristics, because in the stem there is sugar, sugarcane plants belong to the grass family (Gramenia) such as rice, corn and others. Linear regression analysis is an indirect approach that is used to measure the effect of the volume of sugarcane juice on the wages of workers in the sugar mill Sulaiman Ali sugarcane mill, Ketol District, Central Aceh Regency. The results of the linear regression analysis obtained from the research results are the equation = 7179,497 + 14,464 X1. Where it means that every increase in the total volume of sugarcane juice by 14,464 will increase the wage income of milling workers at the Sulaiman Ali sugarcane refinery, Ketol District, Central Aceh Regency, amounting to Rp. 14,464 /person with an average income of Rp. Rp 34,656.25/person/one production process.

Abstract:

In the Rio Grande Valley of Texas (RGV), values of maize and cottonseed crops are significantly reduced by aflatoxin contamination. Aflatoxin contamination of susceptible crops is the product of communities of aflatoxin producers and the average aflatoxin-producing potentials of these communities influence aflatoxin contamination risk. Cropping pattern influences community composition and, thereby, the epidemiology of aflatoxin contamination. In 2004, Aspergillus parasiticus was isolated from two fields previously cropped to sugarcane but not from 23 fields without recent history of sugarcane cultivation. In 2004 and 2005, A. parasiticus composed 18 to 36% of Aspergillus section Flavi resident in agricultural soils within sugarcane-producing counties. A. parasiticus was not detected in counties that do not produce sugarcane. Aspergillus section Flavi soil communities within sugarcane-producing counties differed significantly dependent on sugarcane cropping history. Fields cropped to sugarcane within the previous 5 years had greater quantities of A. parasiticus (mean = 16 CFU/g) than fields not cropped to sugarcane (mean = 0.1 CFU/g). The percentage of Aspergillus section Flavi composed of A. parasiticus increased to 65% under continuous sugarcane cultivation and remained high the first season of rotation out of sugarcane. Section Flavi communities in fields rotated to non-sugarcane crops for 3 to 5 years were composed of <5% A. parasiticus, and fields with no sugarcane history averaged only 0.2% A. parasiticus. The section Flavi community infecting RGV sugarcane stems ranged from 95% A. parasiticus in billets prepared for commercial planting to 52% A. parasiticus in hand-collected sugarcane stems. Vegetative compatibility assays and multilocus phylogenies verified that aflatoxin contamination of raw sugar was previously attributed to similar A. parasiticus in Japan. Association of closely related A. parasiticus genotypes with sugarcane produced in Japan and RGV, frequent infection of billets by these genotypes, and the ephemeral nature of A. parasiticus in RGV soils suggests global transport with sugarcane planting material.

Abstract:

The concern with the sustainability of agricultural production has encouraged the search for alternative management of soil fertility, reducing the use of mineral fertilizers and increasing the use of organic materials. The use of filter cake as a fertilizer has expanded in the sugarcane fields. However, despite some studies confirming its technical viability, it is not verified the widespread used. The aim of this work was to plan and execute a research project to obtain an overview of the perception of researchers and rural producers about the use of filter cake in the fertilization of sugarcane culture, using the PMBOK guide. The planning and execution of the study project addressed two areas of knowledge in project management: scope and time. A questionnaire was made on the Google Forms platform for the main project stakeholders (rural producers, researchers and employees in the sugar and alcohol sector). The participants understand that the search for sustainability in the cultivation of sugarcane is not only a market trend, but also a strategy for their business and / or research, and that they are up-to-date on the trends in the sector in which they work and are in agreement with their aim of achieving a more sustainable production system. We concluded that the perception of stakeholders about the use of filter cake as a fertilizer in the cultivation of sugarcane is positive, however, actions are necessary to reconcile both the interests of users and those of the suppliers of filter cake.

Abstract:

Abstract The sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), has become a major pest of grain sorghum, Sorghum bicolor (L.) Moench, in the United States in recent years. Feeding by large densities of sugarcane aphids causes severe damage, which can lead to a total loss of yield in extreme cases. Our objective was to determine the effect of grain sorghum planting date on sugarcane aphid population dynamics and their potential to reduce yields. We conducted field experiments from 2015 to 2017 in which an aphid-susceptible grain sorghum hybrid was planted at four different dates, which encompassed the typical range of planting dates used in Arkansas production systems. Plots were either protected from sugarcane aphid feeding using foliar insecticide sprays, or left untreated to allow natural populations of sugarcane aphids to colonize and reproduce freely. Planting date impacted both the magnitude and severity of sugarcane aphid infestations, with the highest population densities (and subsequent reductions in sorghum yield) generally occurring on plots that were planted in May or June. Sugarcane aphid feeding reduced yields in the untreated plots in two of the four planting date categories we tested. Earlier planting generally resulted in less sugarcane aphid damage and improved yields compared with later planting dates. While the effect of planting date on sugarcane aphid populations is likely to vary by region, sorghum producers should consider grain sorghum planting date as a potential cultural tactic to reduce the impact of sugarcane aphid.

Abstract:

Sugarcane mills (SCMs) and sugarcane suppliers (SCSs) use different production systems. To increase competitiveness, these systems use cost reduction, high productivity investment, and technology strategies according to their scale of production, that is, small (S), medium (M), or large (L). The question that arises is: which of the three production scales, among SCMs and SCSs, have the best competitiveness index in activities related to soil tillage and sugarcane planting? The objective of this research was to analyze and compare a competitiveness index built by using the values of four variables: planted area, sugarcane replanted area, cost of soil tillage, and cost of planting. The study was conducted with data corresponding to the 2017/18 harvest season from 31 SCMs and 42 SCSs located in Brazil. In addition, Monte Carlo Simulation was used to analyze the level of certain costs and profits through relative frequency. Small scale suppliers showed the highest productivity and lowest cost in soil tillage, while the medium scale sugarcane mills revealed the smallest sugarcane replanting cycle area and the lowest cost of planting. However, the competitiveness index showed that SCSs are more competitive than SCMs, with both kind of sugarcane producers taking the benefits of using cost reduction and high productivity strategies.

Abstract:

The small sugar industry can afford to idle along using Research and development (R & D) produced (and paid for) by other sugar industries but when it is big with world standards it's a different matter. This study was important because Pakistan is 5th largest producer of sugarcane but it still lacks major advancement in production and marketing. The largest producers are Brazil, India, Thailand, China, and Pakistan accounting for more than 70% of world production. Brazil has the highest area (5.34 million hectares) while Australia has the highest productivity a n d s u g a r c a n e y i e l d (85 tons per hectare). Sugarcane is the second largest cash crop of Pakistan and is being cultivated on 1.06 million hectares with 55 t ha cane yield and sugar yield of 5.5 t ha, contributing around 3.6 % of Gross domestic production. The installed capacity of 85 sugar factories is to produce 7.5 million tons of refined sugar and domestic demand is around 4.5 million tons. This shows it’s export potential of 3.5 million tons, annually.

Abstract:

Under utilization of production capacity is a common issue for Nepalese manufacturing enterprises and sugar industry is no exception to this. This study mainly deals with the cause of underutilization of production capacity of Nepalese sugar mills as well as the market situation of sugar and sugarcane. Inspite of sufficient production of sugarcane, the sugar mills do not get adequate quantity and proper quality of sugarcane at right time. Almost half of the sugarcane production has no market which reveals the poor procurement system. The approved production capacity of Nepalese sugar mills is more than domestic requirement of sugar. However, the unfulfilled demand for sugar is fulfilled mainly by imported as well as smuggled Indian sugar. The capacity utilization rate of Nepalese sugar industry, which has been decreasing, dropped to 45percent in FY 2008/09. The main identified reasons are stoppage, breakdown and slow motion of machines, delay in settlement of minimum support price of sugarcane and late commencement of production season, political instability, less operation days of sugar mills and ultimately the overlook of sugar producers to utilize their full capacity of production. Measures to improve the capacity utilization rate of sugar mills have become an urgent need.

Abstract:

Fungi are plentiful in nature and they are found growing on wastes of wood materials. These wastes are equally found in our environment with no usefulness. The aim of this study was to exploit the probability of the isolated fungi from fruits to produce cellulase from wastes of lignocellulosic materials. Cellulase- producing fungi were isolated from fruits (tomato, banana, plantain). The organisms were screened for cellulase production. Culture conditions were optimized with pH, temperature and carbon. Cellulase was produced using lignocellulosic wastes; sawdust, corn cob, sugarcane bagasse. Six cellulase producers were isolated, four of which were selected for synthesis and quantification of the cellulase. The fungi were identified as Saccharomyces cerevisiae4, Trichoderma species1 and Scopulariopsis brevicaulis1. Of all the tested substrates used in this study, pretreated sugarcane bagasse at 3% w/v concentration with Scopulariopsis brevicaulis gave highest cellulase production 18.18 U/mL at 40°C, 5day incubation time and pH 5, followed by Trichoderma with 12.39 U/mL. These fungi are good potentials cellulase producers that can be considered at industrial level.

Abstract:

Sugarcane honey (SCH) is a syrup produced on Madeira Island and recognized by its unique aroma, a complex attribute of quality with an important influence on the final consumer’s acceptance of the product, and determined by a complex mixture of a large number of volatile organic compounds (VOCs) generated during its traditional making process and storage. Therefore, the purpose of this study was to establish the volatile profile of genuine SCH produced by a regional certified producer for seven years and compare it with syrups from non-certified regional producers and with producers from different geographical regions (Spain, Egypt, Brazil and Australia), as a powerful strategy to define the volatomic fingerprint of SCH. Different volatile profiles were recognized for all samples, with 166 VOCs being identified belonging to different chemical classes, including furans, ketones, carboxylic acids, aldehydes and alcohols. Chemometric analysis allowed (i) the differentiation between all syrups, being more pronounced between SCH and other syrups; and (ii) the identification of 32 VOCs as potential markers for the traceability and authenticity of SCH on the global market.

Full text

Abstract:

Achieving high yields is a challenge for sugarcane producers due to the diverse environmental conditions to which the crop is subjected. In tropical and subtropical regions, where sugarcane is typically cultivated, crop diseases are common. This necessitates the development of disease management techniques. Among these techniques, chemical control is of particular significance due to the development of new antifungal agents, such as pyraclostrobin. For some crops, pyraclostrobin has a positive influence on yield due to its effects on plant physiology. The aim of this study was to evaluate the physiological responses and yield of three sugarcane cultivars treated with the fungicide, pyraclostrobin. The experiment was performed in a randomized block design (RBD) with a split-plot arrangement; the variables analyzed were the application or non-application of fungicide in the plots and, in the subplots, the evaluation times after fungicide application. Both the rate of photosynthesis and the antioxidant enzyme (Superoxide Dismutase, Catalase and Ascorbate Peroxidades) activity increased in plants treated with fungicide in comparison to untreated plants, and in the RB855156 cultivar the stomatal conductance, transpiration, and nocturnal respiratory rate were increased. Furthermore, application of pyraclostrobin increased stalk yield and the green biomass index in the RB855156 and RB86751 sugarcane cultivars. In certain cultivars of sugarcane, application of pyraclostrobin leads to an increased yield.

ABSTRACT The knowledge on reliable estimates of areas under sugarcane cultivation is essential for the Brazilian agribusiness, since it helps in the development of public policies, in determining prices by sugar mills to producers and allows establishing the logistics of production disposal. The objective of this work was to develop a methodology for mapping the sugarcane crop area in the state of Paraná, Brazil, using images from the Landsat/TM/OLI and IRS/LISS-3 satellites, for the crop years from 2010/2011 to 2013/2014. The mappings were conducted through the supervised Maximum likelihood classification (Maxver) achieving, on average, an overall accuracy of 94.13% and kappa index of 0.82. The correlation with the official data of the IBGE ranged from moderate to strong (0.64 ≤ rs ≤ 0.80) with average agreement (dr) of 0.81. There was an increase of 2.73% (18,630 ha) in the area with sugarcane in Paraná between 2010/2011 and 2013/2014.

Abstract:

Jamaica is heavily dependent on fossil fuels to meet its energy demand and is currently seeking to reduce consumption. Accordingly, it is essential to investigate the expansion of renewable energy systems to achieve its 2030 renewable energy goal of 50%, with 70% diversification in energy types, as outlined in the National Energy Policy 2009–2030. This study explores biogas feasibility in Jamaica and discusses the potential for electricity generation from combinations of dairy cow and Swine feces with sugarcane bagasse. The study’s primary purpose is to assess the feasibility of biogas production from livestock manure and sugarcane bagasse for electricity generation and manure treatment. Findings reveal that biogas anaerobic digestion and the co-digestion of different varieties of animal manure with sugarcane bagasse can generate up to 122,607.68 MWh or 2.49% of Jamaica’s total electrical energy generation in 2019. The findings indicate a high potential for the installation of community-based plants. Moreover, considering all scenarios and the remaining feedstock, potential electrical energy increases to 222,868.60 MWh (4.53% of total energy generation). This power may be fed to the electrical grid network or consumed by local producers. In addition, electric power generation from animal manure and sugarcane bagasse is feasible with improved technical capability and human development. Additionally, anaerobic digestion and co-digestion of sugarcane bagasse plus animal manure offer an excellent solution to mitigate climate change.

Abstract:

The sugarcane (Saccharum spp. L.) mechanical harvesting system leaves a large amount of straw mulch on the soil surface. The straw mulch may affect soil conditions, root regrowth, and sugarcane yield. Thus, this study assessed the response of sugarcane root system growth and stalk yield to different rates of straw removal. An experiment was conducted in a Rhodic Kandiudox with sand clay loam texture to test the impact of four rates of straw removal: no removal (18.9 Mg ha−1 of dry mass); moderate removal (8.7 Mg ha−1); high removal (4.2 Mg ha−1) and total removal on sugarcane root system and stalk yield. Higher concentrations of roots (60%) were found in the first 40 cm of soil. Moderate straw removal resulted in higher root mass (3.6 Mg ha−1) and stalk production (23 Mg ha−1 of dry mass). However, no straw removal reduced root mass by <40% (2099 kg ha−1) and reduced stalk yield by >20% (105 Mg ha−1). Through regression analysis, it was estimated that retaining between 8.5 and 13 Mg ha−1 of straw resulted in the highest root mass and stalk yield. Managing straw removal to retain a moderate amount enables producers to sustain suitable soil conditions for sugarcane root growth and stalk production while providing straw for industrial use.

Abstract:

The severity of corky root disease (Rhizomonas suberifaciens Van Bruggen et al.) increases with continuous lettuce (Lactuca sativa L.) cropping and exerts a negative impact on the quantity and quality of the lettuce produced. Experimental data from commercial fields were used to analyze profitability outcomes resulting from various management strategies, including cultivars, locations, and field cropping history, to control corky root. Regardless of the field cropping history, net returns were not negatively affected when resistant cultivars were planted. For susceptible cultivars, even when considering land development costs, producers maximize net returns by planting lettuce following sugarcane in land not previously cropped to lettuce. After the first crop of lettuce following sugarcane, yields slowly decreased but remained profitable for three to four crop cycles.

Abstract:

The rapport between international trade and income inequality came to light after the Heckscher–Ohlin/Stolper–Samuelson theorem (HOS). Nevertheless, researchers have not concluded whether the HOS theory truly reflects reality. Even though the main focus provided by the HOS theory is on internal inequality (existing inside the country among its population), another way of analyzing the HOS theory is through income inequality among countries. This last possibility is also called income convergence. This work contributes to the topic of researching the relationship between the export of sugarcane-derived products and income to verify the income convergence effect. The cultivation of sugarcane is a relevant activity for many developing countries, including Brazil. In addition, no developed country is listed among the eight biggest sugarcane producers, which indicates that as a developing country product, it would be possible to analyze the relationship among the variables in a broader sense. The results obtained in the research indicate that the impact of the export of sugarcane products on income is minimal. Although positive, it is only perceived over time. Due to the characteristics of this research, which involves performing an analysis involving green production, green energy, and income inequality, this study is related to the seventh, eighth, and tenth United Nations’ SDG goals.

Abstract:

The economic development of a country depends on the use of energy in various processes, the use of natural sources to generate energy resources has great potential. Environmental issues such as global warming have aroused interest around the world regarding bioenergy, such as biomasses that generate a low carbon impact and are susceptible to transformation, such as sugarcane and corn. The study aims to evaluate the main energy crops and their transformation processes, as well as obtain an overview of the main bioethanol producing countries and analyze the productivity of ethanol from sugarcane and corn. Exploratory research was carried out, using published databases related to the topic and classification by relevance. It was possible to observe that the main ethanol producers in the world are the United States, using corn, and Brazil, using sugarcane and recently corn, the production of first-generation ethanol from these biomasses has different processes, where sugarcane is capable of direct fermentation, whereas corn fermentation is indirect. The production of ethanol from corn has increased in recent years in Brazil and has generated a great industrial and economic development. This concludes the importance of using biomass as a precursor of energy in the development of a country.

Abstract:

Sugarcane spirit is a drink considered as a national symbol of Brazil. It is produced by large producers and by about 30 thousand small and medium home-distilling producers dispersed throughout the country. The copper originating from the home-distillers can become a serious problem since at high concentrations in beverages it may cause serious human health problems. Therefore, the objective of this study was to investigate the influence of the activated carbon used in commercial filters on the physicochemical and sensory characteristics of aged sugarcane spirit. Analyses of copper, dry extract, alcoholic degree, higher alcohols, volatile acids, aldehydes, esters, furfural, and methanol were performed. The sensory evaluation was performed by seven selected trained judges, who analyzed the yellow color, woody aroma and flavor, and intensity of alcoholic aroma and flavor of the cane spirit before and after the filtration process. The sensory tests were carried out using a 9 cm non-structured intensity scale. A reduction was observed in all compounds analyzed physicochemically, except for the esters, which increased after filtration. This increase is probably due to the esterification of the alcohols and acids present. According to the sensory results obtained, a reduction was observed in the intensity of the yellow color, aroma, and wood flavor characteristics, the major characteristics of the aging process.

Abstract:

This article examines the evolution of the credit market for small-scale sugarcane producers in the Plan Chontalpa development program in Tabasco, Mexico. The plan promoted neoliberal policies that transformed the existing credit market available to small-scale producers. The availability of credit was supposed to lead to increased efficiency. However, making credit available to low-income farmers can result in unintended outcomes. We found that many households had high discount rates and used the credit to supplement their household income. Thus, farmers are getting caught in a cycle of debt that often culminates in losing their land. We use a life history to consider the strategies the program has adopted to control credit as well as the counterstrategies the families have developed.

Commodity prices are generally better modeled by a long-term Mean Reverting Process, than by a Geometric Brownian Motion stochastic diffusion process, which is more generally used to value real options, since it is simpler to use. In this article we model two correlated uncertain variables using a mean reversing process bivariate lattice to value the switch option between outputs available to ethanol and sugar producers, using the same source: sugarcane. The model results show that the switch option adds a signiﬁcant value for the producer income. The article also shows that when modeled by a geometric brownian motion, the switch option yields signiﬁcantly higher values than with a mean reverting model, for the option itself as much as for the base case without ﬂexibility. This conﬁrms that the stochastic model chosen can inﬂuence signiﬁcantly the option value.

Abstract:

Sugarcane is the most promising crop among renewable biofuels producers and one of the countries that produces the most green matter per unit area, whose greater limitations to productivity are mainly related to the adequate availability of water and mineral nutrients, in particular nitrogen (N). Based on the hypothesis that the source and the availability of nitrogen influence the growth, development and yield of irrigated sugarcane in the cerrado region. The objective of this study was evaluate the biometric variables and yield of irrigated sugarcane, in the cane-plant cycle, as affected by source and nitrogen rate. The soil utilized was an Oxisol (Rhodic Hapludox), cerrado (savannah) phase. The experiment was carried out at Farm of the Raízen Mill, located in the municipality of Jataí, Goias State, Brazil. The variety IACSP95-5000 was used in a randomized block design, analyzed in a split-split-plot scheme, with three replicates. The treatments were four N rates (0, 60, 120 and 180 kg ha-1); two fertilizer sources (urea and ammonium nitrate). The factors evaluated were in the plots of four doses of N (0, 60, 120 and 180 kg ha-1). In the subplot two sources of N (urea and ammonium nitrate) and as sub-subplot were represented by four evaluation periods (210, 250, 290 and 330 days after the planting-DAP). The irrigation was by sprinkling, in a central pivot. The evaluated variables were: plant height, stalk diameter, total number of leaf, leaf area, number of industrializable tillers, stalk yield, pointer yield and total recoverable sugars. The highest stalk yield, pointer yield and total recoverable sugars occurred at the average dose of 143.61 kg ha-1 of N, with an average increase of 25.87%.

Abstract:

The importance of adopting technology innovations, mainly in food production contributing to food safety, is significant. This study aims to analyze the diffusion of agricultural production technologies in Brazil, mainly the use of wheel tractors, grain and sugarcane harvesters by producers. A quantitative approach is used to understand the market-level factors that influence the adoption of technologies. A supply response is estimated based on the Bass diffusion model. Data were collected from the National Association of Vehicle Manufacturers (Anfavea), which includes Brazilian monthly sales information for wheel tractors, grain and sugarcane harvesters. For each agricultural machine, 700 months of sales records were collected. The imitator’s coefficients were higher than innovators for all types of machines studied. The data showed that, for wheel tractors and grain harvesters, the diffusion curve presented S format (S-curves). However, sugarcane harvesters had a different pattern of diffusion. The distribution of the investigated technologies in Brazil was an imitation process; the market saturation was observed for wheel tractors and grain harvesters. This study helps to comprehend the supply response of agricultural machinery and presents suggestions for the diffusion of agricultural production technologies in Brazil. The experience has shown that several factors can constrain technology adoption, such as lack of credit, limited access to information and inputs, and inadequate infrastructure.

Full text

Abstract:

Growing domestic and international ethanol demand is expected to result in increased sugarcane cultivation in Brazil. Sugarcane expansion currently results in land-use changes mainly in the Cerrado and Atlantic Forest biomes, two severely threatened biodiversity hotspots. This study quantifies potential biodiversity impacts of increased ethanol demand in Brazil in a spatially explicit manner. We project changes in potential total, threatened, endemic, and range-restricted mammals’ species richness up to 2030. Decreased potential species richness due to increased ethanol demand in 2030 was projected for about 19,000 km2 in the Cerrado, 17,000 km2 in the Atlantic Forest, and 7000 km2 in the Pantanal. In the Cerrado and Atlantic Forest, the biodiversity impacts of sugarcane expansion were mainly due to direct land-use change; in the Pantanal, they were largely due to indirect land-use change. The biodiversity impact of increased ethanol demand was projected to be smaller than the impact of other drivers of land-use change. This study provides a first indication of biodiversity impacts related to increased ethanol production in Brazil, which is useful for policy makers and ethanol producers aiming to mitigate impacts. Future research should assess the impact of potential mitigation options, such as nature protection, agroforestry, or agricultural intensification.

Brazil has a long tradition of bioethanol production from sugarcane. Following the Middle East crisis in the 1970s, the oil price increased twofold, doubling Brazil’s spending on oil imports. As a result, the country had to find an alternative type of fuel to reduce its expenditure on conventional petrol fuels. With its vast tropical land conditions, the Brazilian government then put massive effort to establish the infrastructure and research of bioethanol from 1975 and 1989. Research plays a pivotal role in the success of Brazil’s ethanol industry. The country was heavily criticised at the beginning of the programme, but today, Brazil is the second-largest ethanol producer after the USA. Brazil produces the cheapest ethanol in the world and does not depend on fossil fuel to supply its energy demand. Indonesia and Brazil share the same landscape and geographical advantages. This paper aims to discuss the success of the Brazilian bioethanol industry and draw important lessons from it. In a nutshell, Indonesia should increase bioethanol production from renewable sources. Also, the modernization of distilleries facilities, the establishment of new production plants, the introduction of subsidies and the reduction of taxes for ethanol producers are needed. In summary, apart from massive research and development, we concluded that effective and strong long-term government commitment play important role in shaping the future of the Indonesian bioethanol industry.

Abstract:

Abstract Corn and sugarcane-base bioethanol dominantly contributes to the 25 billion gallons of bioethanol worldwide. Recent researches focused on the potential microbes and biomasses for optimum production. This study is, therefore, aimed to screen the bioethanol generating yeast strains of Biotechnology Culture Collection (BTCC), isolated from chocolate fermentation in several medium containing various carbon sources. A total of 72 yeast strains were grown in the media containing sugarcane juice, sorghum juice, and molasses, which served as carbon sources. Based on 26S rDNA gene analysis, these species were included in 9 genera, encompassing Saccharomyces (63.9%), Hanseniaspora (9.7%), Candida (0.7%), Torulaspora (0.4%), Pichia (0.8%), Issatchenkia (0.1%), Wickerhamomyces (0.3%), Metschnikowia (0.1%), and Rhodotorula (0.1%). Therefore, spectrophotometer UV-Vis was used to analyze cell growth, while the fermentation products (sugars and ethanol) were evaluated using the HPLC, and about 70 strains produced bioethanol. The highest yields were obtained during fermentation, using sugarcane juice, molasses, molasses waste, and sorghum juice, at concentrations of 43, 50, and 7 g/L, respectively. Furthermore, the Saccharomyces cerevisiae strain were the most significant producers, as the genus was able to generate various concentrations from several carbon sources. However, the only genus without the ability to yield any related products during fermentation was Pichia (0.8%). Based on these results, it is necessary to further develop the yeast strains from chocolate fermentation, due to the potential for bioethanol production from biomasses.

Abstract:

The Indonesian government is gradually reducing its dependence on petroleum fuels by mixing it with biofuels. One of the biofuels used is bioethanol made from molasses. This study aims to analyze the potential for sugarcane development at the farm level, identify bioenergy problems, and provide bioenergy development recommendations based on molasses. The research was conducted in East Java Province in 2016, with updated data in 2019. The analytical methods used were quantitative and qualitative. The results of the research are as follows. In 2019, the potential of molasses produced reached 260.06 thousand tons in East Java Province. However, there are some technical and socio-economic problems in developing biofuels from molasses, including the low yield of sugar, limited processing of molasses into bioethanol, lack of bioethanol marketing guarantee, and lack of synergy in bioethanol policy development. Some policy recommendations proposed to support the sustainability of bioethanol production in the future are policy supports for increasing sugarcane farming, capital support for bioethanol producers, guarantee in the bioethanol marketing, and synergies in developing bioenergy policies.

Abstract:

Brazil is oneofthe largest sugarcane producers around the world, however the effects concerning environment issues in soil are still no well described.Soilelectrochemical can provide important information about residues uses and environmental contamination, andthenzeropointof charge (ZPC)is a parameter that may demonstrate this variation. In this study, It wasanalyzedthesoil behavior when submitted to sugarcane vinasseapplication in different doses simulating high and low doses application as regularlydone by the manufacturesin typical tropical weathered oxisols. To procedure ZPC test, microcosmsexperiment wasmanagedwith all parameters measured and controlled in a factorial design:2 soil depths (superficial group–0.0 –20.0 cm and sub-superficial group–60.0 –80.0 cm), 3 salt concentration (0.002; 0.02 and 0.2 mL NaCl), and 4vinassedoses (Without application;Low –164.28 mL L-1; Intermediate –328.57 mL L-1and High657.14 mL L-1), after incubation all the samples were measured electrochemically.Based on these analyses, data rised two main highlights: 1. vinasselow dosesbehaved like a buffer solution, 2. High doses in sub-superficial layer disturbed ZCP. Then, vinasse seems correlate with lixiviation capacity, and then over-applications can disrupt soil solution on this soil.

Abstract:

In numerous product lines, globalization of production has been accompanied by increasingly austere product quality and safety regulations. These regulations are particularly stringent in the food and beverage sectors and put enormous strain on producers from developing nations. This article examines a cooperative of sugarcane, sugar, and ethanol producers from Brazil that, when confronted with the challenge of new regulations, adopted three policies that encouraged its members to upgrade quality and safety standards, enabling them to compete successfully in a demanding business environment. I argue that the co-op’s success was due to (1) a new cost accounting methodology that monetized some of the differences in product quality, attenuating tensions among members; (2) a low-cost, high-powered system of regulatory incentives that empowered middle managers vis-à-vis top executives within regulated firms; and (3) external auditors who acted not as police officers or consultants but as conduits, reestablishing information flows and helping to create a business atmosphere conducive to productive change.

Abstract:

Abstract Due to growing topicality of indirect land use change, greater shift towards second generation biofuels should be observed. In order to help smaller biogas and bioethanol producers, multi-criteria analysis of lignocellulose pre-treatment is conducted to elucidate the most preferable approach for lignocellulose pre-treatment. There are four main pre-treatment groups – biological, chemical, physical and physochemical pre-treatment. In this article three pre-treatment types were described by highlighting their specific approaches; using multi-criteria analysis a conclusion was reached that the most preferable pre-treatment option for lignocellulose biomass like corn stover or sugarcane is microbiological pre-treatment, as it showed the closest proximity to ideal solution.
