Relevance. Onion is one of the most important vegetable crops of the borscht group, in the NonChernozem zone it is cultivated mainly through sowing, but modern technologies of cultivation of new varieties and hybrids of intensive type, drip irrigation, new types of mineral and organic fertilizers and plant growth regulators allow to obtain a high yield of onions (50 – 70 t/ha) in an annual crop in conditions of fertile alluvial soils and dramatically increase the profitability of production. Onions grown from seeds, as a rule, respond poorly to the use of large doses of mineral tuks due to the increased concentration of soil solution and a decrease in the density of standing plants.Material and methods. Research in 2014-2020 were carried out on the experimental field of the Department of Agriculture and Agrochemistry of VNIIO – a branch of the Federal State Budgetary Scientific Institution of the Federal Scientific Research Center on the alluvial meadow soil of the central part of the Moskvoretskaya floodplain (Ramenskiy district, MO). The experiments were carried out in 3 replicates, with a systematic distribution of replicates. As the main mineral fertilizer, nitroammophoska was used, containing 16% of ae. nitrogen, phosphorus and potassium. As organic fertilizers, we used biocompost of cattle, horse and chicken manure from TONEKS LLC, a domestic manufacturer of agrochemically and agronomically valuable bioorganic products of the BIUD family.Results. These studies made it possible to find out that biocompost from cattle manure, horse and chicken manure in balanced doses with mineral fertilizers for nitrogen, as well as growth regulators Zircon and Argolan, can significantly increase the yield of annual onions to 58.8-66.4 t/ha while increasing the standard of bulbs without reducing the biochemical quality indicators. The most effective were chicken manure (16% increase), Argolan (21% increase) and Zircon (10-21% increase in the yield of different hybrids).

In the he article are presented the research result on effectiveness of application new form of urea on potato. New urea form is urea with urease inhibitors. This fertilities type allow to reduce losses of nitrogen in ammonium form. Field experiment was carried out in 2017 on solonetc light chestnut soils with heavy granulometric compound in the conditions of the Volgograd region in the experimental polygon of the lower Volga agricultural research Institute – branch of Federal state budgetary scientific institution "Federal scientific center for agro-ecology, integrated land reclamation and protective afforestation wounds". As an object of research used potatoes mid-early table varieties Nevsky. The advantage of a new fertilizer form is the yield increase and improvement of tubers quality. Urea UTEC application leads to formation bigger and uniform tuber size. The use of urea UTEC provide the potato yield of 56.4 t/ha, with marketable tubers fraction up to 54.82 t/ha, the total yield increase to the control – 35.6%, in monetary terms this amounted to 245887.0 RUB/ha additional profit. Under these conditions, was obtained lowest amount of non-marketable yield – 0.16 t/ha, which is 2.65 times less than in the control variant. The advantage of urea UTEC application in comparison with ammonium nitrate was the increase in the yield of marketable potatoes by 5.1 t/ha and an additional profit up to 76.8 thousand rubles/ha. The Assessment of the potato quality showed that the best treatment was also the treatment with UTEC urea, the starch content in tubers was 9.22%. Note that almost the same value of the indicator in the variant with the use of urea (option 2), and the lowest starch content was noted when using ammonium nitrate – 9.05%.

Research was carried out on the basis of the laboratory of breeding and seed production of legumes Federal state budgetary scientific institution "Federal scientific center of vegetable growing" (Moscow region) in 2013-2017. The study included 22 varieties of vegetable pea, differing in the length of the growing season and a weigt of 1000 seeds. Sowing was carried out in the optimal time, repeat the experience fourfold. Seeding rate 100-110 seeds per 1 m2. The selection of seeds four times on each plot. The sign «weight of 1000 seeds» determines the grain size and is the most important in the production of canned «green peas». With the increase in grain size decreases marketability of products, increases the consumption of seeds for sowing, significantly reduces the multiplication factor, which leads to higher prices of products. Therefore, varieties with a weigt of 1000 seeds 200-220 grams are mainly used for freezing. Industry currently uses varieties characterized by an average grain size (7-10mm) and a weight of 1000 seeds less than 200 grams, promising grades with a mass of 100-140 grams. To accelerate the selection process for creating varieties with specified parameters, a detailed analysis of the characteristics of the productivity of the initial material, in particular, the weight of 1000 seeds, is needed, since samples with an average size (160-200 grams) have a low coefficient of phenotypic variability and depend on the interaction of genotype and environment, but the reaction of each genotype to the environment is specific. Work should include samples with the lowest coefficient of variability. When working with finely seeded specimens, the average level of phenotypic variability should be taken into account and, when included in the breeding process, increase the selection sample.

Relevance Traditional breeding methods are based on crossing and selection of genotypes among hybrid offspring. In recent decades, along with traditional methods, more and more attention is paid to alternative methods of selection, based on biotechnological manipulations with plants. One of the most important methods of biotechnology is the method of cell selection, which is based on the replacement of the whole plant, as a unit of selection, on its cell. Applying biotechnology techniques from a single plant can produce millions of cells, which increases the chances of finding, eliminating the need for areas for the cultivation of tested plants. As well as accelerating the selection process due to the possibility to carry out the study in the offseason. Methods The studies used the linear material of C. sativus hybrids of All-Russian Scientific Research Institute of Vegetable Growing – Branch of the FSBSI Federal Scientific Vegetable Center and Agroholding "Poisk". Plants were cultivated in laboratory room conditions. As explants used hypocotyl 0.5-1 cm segments isolated from young plants. Results To obtain Cucumis sativus plants with increased resistance to Fusarium by cell selection method, it is recommended to alternate culturing of callus on a non – selective medium containing sucrose in a concentration of 30 g/l, agar – 7 g/l, 0.1 mg/l, NUC – 0.5 mg/l and the filter of the cultural fluid of the fungus in a concentration of 10% within 3 passages.

Relevance. Maintaining the phytosanitary condition of vegetable and melon crops is an important component in the technologies of cultivation of new and promising varieties and hybrids, since losses from diseases of various etiologies reach 30% or more. This determines the need for immunological studies of the resistance of vegetable and melon crops to phytopathogens of various etiologies, where the basis of the strategy for creating new varieties and hybrids is the joint work of a breeder and a phytopathologist. To do this, it is important to conduct an annual study of the species composition in order to identify new harmful objects that have a negative impact on the profitability of production, as well as to develop measures to protect vegetable crops from the most harmful and economically significant pests and diseases.Methodology and Results. The extensive experimental network of the Federal Scientific Vegetable Center (FSBSI FSVC) in various ecological and geographical zones allows testing varieties and hybrids of vegetable and melon crops in various soil and climatic conditions, including evaluating them for the most harmful phytopathogens in these regions. This review article briefly highlights the main stages of the history of development and current trends in phytopathological research in Russia and our center. The most significant achievements of scientists of the FSBSI FSVC are presented, aimed at a comprehensive study of the current state of populations of pathogens on vegetable and melon crops, resistance factors controlling the interaction of organisms in pathosystems, including genetic ones, optimization and development of new methodological approaches in breeding for immunity and scientific justification of recommended modern protection systems.

A comparative characteristic of the former and the wide-row version in terms of energy consumption and fuel consumption is givenAuthors´ Contribution: All authors contributed to the planning and setting up the experiment, aswell as in the analysis of experimental data and writing of the article.Based on the results of the selection work of the Primorsky Vegetable Experimental Station for the period 1993-2023, the station bred and released 56 varieties and hybrids of 19 main vegetable crops. The experience of the Primorsky branch of the Federal scientific vegetable center allows organizing production at a modern level, taking into account the rich experience of other regions of Russia. In conditions of monsoon climate and soils of heavy granulometric composition, with a general lack of heat, their fertility is negatively affected by a large number of external factors. To grow vegetables, a set of measures is needed for serious drainage and irrigation reclamation (creation of polder systems with the laying of systematic plastic drainage) against the backdrop of ridge-ridge cultivation technology, fine irrigation system). The developed wide-cut technology and a set of machines make it possible to introduce a resource-saving technology that saves energy costs and fuel.

Introduction. The development of ideas about the influence of the light environment - the radiation spectrum, intensity and duration of exposure, on the physiology of plants, serves as the basis for the creation of effective light sources for protected ground.Purpose. Comparative test of the influence of a light environment with different spectral composition on the productivity and quality of tomatoes in conditions of intensive photo culture.Methods. Investigations were made under controlled conditions of intensive photoculture when growing dwarf tomatoes of the variety Natasha selections of the “Federal Scientific Vegetable Center” on thin-layer soil analogs with the supply of a nutrient solution to the plant roots through a slit capillary in vegetative light installations developed at the ARI. The light sources were high-pressure sodium lamps and LED lamps SD1, SD2, and SD3 with different emission spectra. Results. Tomatoes of the Natasha variety, illuminated during development with HPS lamps, formed almost the same yield with an average fruit weight of 42.5 kg/m2 per layer per year. Natasha tomato grown under LED lamps showed a tendency to lower productivity by 29% under SD1 and by 8% under SD2 and higher by 19% under underSD3 compared to that under HPS lamps. A comparative assessment of the biochemical composition of tomato fruits indicates their high quality under all tested light sources.Conclusion. Cultivation of dwarf tomato varieties on thin-layer soil analogs showed the best results in terms of productivity with good quality plant products under LED lamps SD3 with a radiation spectrum close to sunlight.
