Résumé :

The remarkable development and application of new genetic The Institute for Vegetable Crops possesses a rich germplasm collection of vegetables, utilized as gene resource for breeding specific traits. Onion and garlic breeding programs are based on chemical composition improvement. There are programs for identification and use of genotypes characterized by high tolerance to economically important diseases. Special attention is paid to breeding cucumber and tomato lines tolerant to late blight. As a result, late blight tolerant pickling cucumber line, as well as late blight tolerant tomato lines and hybrids are realized. Research on bean drought stress tolerance is initiated. Lettuce breeding program including research on spontaneous flora is started and interspecies hybrids were observed as possible genetic variability source. It is important to have access to a broad range of vegetable genotypes in order to meet the needs of organic agriculture production. Appreciating the concept of sustainable agriculture, it is important to introduce organic agriculture programs in breeding institutions.

Résumé :

This paper originates from an address at the 8th International Symposium on Nitrogen Fixation with Non-Legumes, Sydney, NSW, December 2000 Azospirilla are free-living rhizobacteria that are able to promote plant growth and increase yields in many crops of agronomic importance. It is assumed that the bacteria affect plant growth mainly by the production of plant growth promoting substances, which leads to an improvement in root development and an increase in the rate of water and mineral uptake. In the present review, we discuss the physiological responses of the plant roots to inoculation with Azospirillum, and report on field and greenhouse experiments carried out with these bacteria during 1994–2001 in Belgium, Uruguay, Mexico and Israel.

Résumé :

Weeds are a major contributor to yield loss and reduction in yield quality in an agricultural setting, competing with the crop for resources like light, water, and nutrients. This competition along with the cost of weed management strategies like tillage and herbicides, are responsible for the economic impact of weeds, which can reach into the billions. In addition to the damage caused by direct competition, weeds can also harm crop plants by acting as reservoirs for destructive plant pathogens, the insect vectors that move these pathogens from plant to plant, or both. The objective of this publication is to summarize previously published weed-pathogen associations to help growers scout and monitor pathogens in weeds near production areas.https://edis.ifas.ufl.edu/hs1335

Résumé :

The study mainly aims at estimating the economic effects of manufacturing the most important horticultural crops in Egypt, through estimating the added value of the food processing process for green okra and orange crops, in addition to developing a future vision for the possibility of advancing the food industry sector through the establishment of some agricultural manufacturing projects that contribute to Economic and social development in Egypt. The results showed that the value of the total loss of green okra and orange crops amounted to about 2909 million pounds in 2021, and it was found that the value added from the process of manufacturing frozen okra and orange crops is estimated at 12450 and 11338 pounds / ton, respectively, while the value of the total margin is estimated for mediators The distribution of frozen okra and orange drink is about 4,250 and 5,750 pounds/ton, respectively. Egypt is represented by the obsolescence of the technologies used in the production process and the high cost of production as a result of the high prices of production inputs, in addition to the high transportation costs. Therefore, the study recommends the necessity of promoting the economic and technical efficiency of agricultural industrialization, especially in the Egyptian countryside, and modernizing machines and equipment for agricultural industrial activities and projects through soft loans to their owners, modernizing and developing them, because of this’s impact on improving the quality and quality of the product, reducing waste and reducing production costs.

Résumé :

Horticulture is an important part of agriculture with many important crops being vegetatively propagated. The objectives of this work were to discuss some of the most important characteristics of vegetatively propagated crops and the breeding strategies to develop and propagate new cultivars. Vegetative propagation enables to fix favorable combinations of important traits, very specific chemical compositions, superior genetic variance interactions and high levels of heterozygosity. Breeding new cultivars involve few possibilities of genetic recombination by sexual reproduction and many generations of selection and vegetative propagation. Marker assisted selection should be useful for genotyping and selecting complementary parents for crossing and for identifying superior genotypes at early stages of selection. The tissue culture technique enables to get disease free stock plants and to maximize its multiplication rate, having an important role in yield and quality of these crops.

Arab Journal of Plant Protection, 41(4): 444-458. https://doi.org/10.22268/AJPP-41.4.444458 Syria is famous for cultivation of many different vegetable crops in most governorates during both winter and summer growing seasons, due to its Mediterranean moderate climate conditions, characterized by a mild winter and a hot dry summer. Vegetables cultivation is a very important sector of the Syrian agriculture, as it represents an important source of income for growers and a source of hard currency through export. The most important vegetables cultivated in Syria are solanaceous crops (potato, tomato, sweet potato, pepper and eggplant), cucurbits (watermelon, melon, cucumber, squash and pumpkin), legumes (broad bean, green bean, green pea and cowpea), cruciferaceous (white cabbage and white cauliflower) and other species such as: green onion, green garlic, lettuce, okra … etc. These vegetable crops are affected by many diseases caused by different causal agents, among them, viruses, viroids and phytoplasmas that are considered the most important pathogens causing many serious and significant diseases. In Syria, during the past forty years, many viruses and few phytoplasmas were investigated and most of them (especially viruses) were recorded on these vegetable crops through many field surveys carried out to evaluate their sanitary status and to determine the economic losses and damages caused by those pathogens. Tens of studies were implemented with the aim of identifying those causal agents on the most important vegetable crops grown in the country and finding out the appropriate approaches for their effective control. Many available and appropriate diagnostic methods such as biological, serological and molecular techniques were used to assess the sanitary status of these crops.

Texte intégral

Résumé :

Many people believe that animal agriculture should be phased out and replaced with vegetarian substitutes. The livestock industry has also been attacked because it uses vast amounts of land. People forget that grazing cattle or sheep can be raised on land that is either too arid or too rough for raising crops. At least 20% of the habitable land on Earth is not suitable for crops. Rotational grazing systems can be used to improve both soil health and vegetation diversity on arid land. Grazing livestock are also being successfully used to graze cover crops on prime farmland. Soil health is improved when grazing on a cover crop is rotated with conventional cash crops, such as corn or soybeans. It also reduces the need for buying fertilizer. Grazing animals, such as cattle, sheep, goats, or bison, should be used as part of a sustainable system that will improve the land, help sequester carbon, and reduce animal welfare issues.

Résumé :

Insect pollinators are responsible for pollination of most the fruit crops and they are performing it well. Pollinator mediated cross-pollination is needed for better production of fruit crops. Many insects such as honey bees, bumble bees, wasps, hover flies, butterflies and beetles are important pollinators but honey bees are the most significant and efficient pollinators of fruit crops. Honey bees are economically very important because they not only help in pollination but provide other valuable products like honey, beeswax, propolis, royal jelly, bee venom and pollen. A survey was conducted to know the farmers` awareness about beehive products in Shimla hills of Himachal Pradesh. It was found that the farmers had knowledge about different insect pollinators visiting various fruit crops. They were practicing beekeeping not only for managed crop pollination but for producing honey also. Only 67% of them were getting extra income by extracting honey from bee colonies. There was very little awareness among the farmers about other beehive products like beeswax, propolis, royal jelly, bee venom and pollens as well as regarding their use as industries, food, medicine, cosmetics and apitherapy. The climate and the conditions of Himachal Pradesh are not favourable for beekeeping. The lack of experts, financial support, labour, transport, honey market, knowledge of diseases and occurrence of winter snow fall at higher altitudes were demoralizing the farmers to make beekeeping as whole time profession. The renovation in all aspects of apiculture and application of improved beekeeping technologies will not only benefit beekeepers but also farmers and general public in pollinating their crops, gaining extra income and maintaining biodiversity.

Résumé :

The influence of the nitrogen fertilization level was investigated relative to the chemical composition of lignocellulosic energy crops and their usefulness as a substrate for the purpose of biogas production. In the case of perennial crops, such as Virginia mallow (VM) and reed canary grass (RCG), the impacts of individual swath and cutting frequency were examined. The results showed that raised nitrogen fertilization improved the biomass quality. This was important for biogas production, primarily through decreased lignin content, and for an increased ratio of structural carbohydrates to lignin. It is believed that this tendency may facilitate the digestion of the tested substrate and increase the methane fermentation efficiency. Likewise, the swath of perennial crops differed significantly in terms of the analyzed properties, which also may have been reflected in the suitability of biomass as a feedstock for biogas plants.

Résumé :

Around the world due to pests and pathogens almost 50% of the agricultural produce is lost which is so alarming given the fact that many people die everyday due to starvation in poor nations. Crop diseases disturb the normal growth and physiological processes. It is estimated that every year 20-40% of crop loss is reported and, in some cases, whole production gets destroyed. So, to produce higher yield and for sustainable agriculture it is important to identify any diseases from the early stage itself. Technology can do a great help in this cause to detect plant disease by using various AI techniques. It is also important to recommend proper pesticides for the persisting disease. The model proposed is based upon a 9 layer resnet deep learning algorithm that takes in present time images of various crops and detects the disease & also recommends the suitable pesticide. Plant Village Dataset taken from Kaggle comprising 87000 images (38 Classes,13 Crops) is used. A custom dataset is also built consisting of disease-description-measures to be taken-pesticide or fertilizer to be used. The end system developed also has two other models integrated that are used for crop and fertilizer recommendations. They are built using the Random Forest Classifier algorithm and a parameter conditional statements function.

Résumé :

Light is one of the most important environmental stimuli impacting plant growth and development. Plants have evolved specialized pigment-protein complexes, commonly referred to as photoreceptors, to capture light energy to drive photosynthetic processes, as well as to respond to changes in light quality and quantity. Blue light can act as a powerful environmental signal regulating phototropisms, suppression of stem elongation, chloroplast movements, stomatal regulation, and cell membrane transport activity. An emerging application of light-emitting diode (LED) technology is for horticultural plant production in controlled environments. Work by our research group is measuring important plant responses to different wavelengths of light from LEDs. We have demonstrated positive impacts of blue wavelengths on primary and secondary metabolism in microgreen and baby leafy green brassica crops. Results show significant increases in shoot tissue pigments, glucosinolates, and essential mineral elements following exposure to higher percentages of blue wavelengths from LED lighting. The perception of energy-rich blue light by specialized plant photoreceptors appears to trigger a cascade of metabolic responses, which is supported by current research showing stimulation of primary and secondary metabolite biosynthesis following exposure to blue wavelengths. Management of the light environment may be a viable means to improve concentrations of nutritionally important primary and secondary metabolites in specialty vegetable crops.

Résumé :

The article deals with the production of crops in agriculture using mineral nutrition. A fertilizer system that provides high-quality crop yields with the lowest cost per unit of production, steadily increases the fertility of irrigated soils. When developing the issue of crop planning, it is important to establish scientifically based doses of fertilizers. Stable yields of alfalfa are possible under the conditions of irrigation, fertilizers, plant protection products – a high crop of agriculture. An important stabilizing factor in crop irrigation is forest strips that allow you to maintain the timing of irrigation at wind speeds exceeding the permissible values for sprinklers. Optimal seeding rates and design of forest strips for obtaining high yields of alfalfa on irrigation have been established.

Résumé :

Abiotic stresses, including drought, extreme temperatures, salinity, and waterlogging, are the major constraints in crop production. These abiotic stresses are likely to be amplified by climate change with varying temporal and spatial dimensions across the globe. The knowledge about the effects of abiotic stressors on major cereal and legume crops is essential for effective management in unfavorable agro-ecologies. These crops are critical components of cropping systems and the daily diets of millions across the globe. Major cereals like rice, wheat, and maize are highly vulnerable to abiotic stresses, while many grain legumes are grown in abiotic stress-prone areas. Despite extensive investigations, abiotic stress tolerance in crop plants is not fully understood. Current insights into the abiotic stress responses of plants have shown the potential to improve crop tolerance to abiotic stresses. Studies aimed at stress tolerance mechanisms have resulted in the elucidation of traits associated with tolerance in plants, in addition to the molecular control of stress-responsive genes. Some of these studies have paved the way for new opportunities to address the molecular basis of stress responses in plants and identify novel traits and associated genes for the genetic improvement of crop plants. The present review examines the responses of crops under abiotic stresses in terms of changes in morphology, physiology, and biochemistry, focusing on major cereals and legume crops. It also explores emerging opportunities to accelerate our efforts to identify desired traits and genes associated with stress tolerance.

Résumé :

Macronutrients play a very important role in plant growth and development. Three main elements are nitrogen, phosphorus, and potassium (N, P, K) and are required in abundance. They must be readily available through soil medium or fertilizer. The secondary elements are sulfur, calcium, and magnesium (S, Ca, Mg). The problem of low soil fertility and poor plant nutrition does not only affect crop yields but also crop quality. Various nutrient elements influence biochemical processes and eventually affect the overall quality of various crops and their products. Depending on the amount that is available for plant uptake, these nutrients influence crop yields and quality and plants treated with absence of nutrients in the nutrient solution showed that N and Ca were the most limiting nutrients to biomass production The crop quality characteristics mostly reported to be affected by plant nutrition include: proteins, carbohydrate, sucrose and fructose content in grains, root crops, tuber crops and fruits; vitamins like beta-carotene content in fruits and tubers; moisture content at storage in cereal grains, potato tuber density; and frying colours, and fruit weight. It has been noted that essential and beneficial nutrient elements contribute to crop quality through functioning as raw materials for the synthesis of various plant components that have food value to humans and animals.

Résumé :

An important factor in increasing the efficiency of crop diversification in West Kazakhstan and reducing the dependence of crop productivity on weather conditions is the expansion of crops most adapted to unsustainable humidification of plants such as chickpeas, Sudan grass, sorghum, corn and sunflower. One of the ways to increase the productivity of Sudanese grass is to use its mixed crops with chickpeas, sunflower, corn and sorghum. Mixtures due to the best quality indicators of feed provide the maximum yield of feed units and digestible protein. The article presents research data on the study of mixed crops of Sudanese grass with annual crops in the conditions of the 1st dry-steppe zone of Western Kazakhstan. A comparative test of mixed crops by yield from digestible protein area units revealed the most nutritionally valuable mixtures. So, in the research of 2018-2020, the largest yield for digestible protein was obtained on the variant using sunflower for silage mixed with Sudan grass (1.65 c/ha), slightly lower on the versions of using a mixture of Sudan grass and corn for silage (1.58 c/ha) and a mixture of sorghum and Sudan grass for silage (1.55 c/ha).

Résumé :

Several Lathyrus species, particularly Lathyrus sativus and L. cicera, have a high potential both as food and fodder crops. Rust and powdery mildew fungi are among the most important pathogens of major grain legumes including Lathyrus species. We review and critically discuss available knowledge of the existence of resistance and the underlying resistance mechanisms against rust and powdery mildew in the L. sativus and L. cicera crop species.
