Stages of the Environmental Risk Assessment

The scientific article is devoted to the greening of technologies and its individual aspects, which is an important agricultural measure that can curb further decline in soil fertility, stabilize production systems, and reduce dependence on technological factors. Of the entire complex of agrotechnical measures in biologically based soybean cultivation technologies, the lowest material and labor costs are incurred for pre-sowing seed treatment with bacterial preparations and treatment of crops with growth regulators. The effect of biological products -growth regulators is due to their influence on the plant organism at certain stages of organogenesis and is associated with significant changes in the process of metabolism, restructuring of a number of metabolic systems. In the course of experimental studies, a variant with seed treatment with Rizogumin-Plus and two-time treatment of crops with the retardant chlormequat chloride was identified by the manifestation of the studied soybean traits: first -in phase of the 3rd trifoliate leaf, second -in the budding phase. The main objective of the research was to study the patterns of manifestation and formation of productivity elements and yield level of soybean agrophytocenoses depending on varietal composition, pre-sowing treatment of seeds with a bacterial preparation and concentration of retardant. During 2018-2022, a three-factor experiment will be conducted in the Right-Bank Forest-Steppe of Ukraine. The material of the research was soybean varieties of domestic selection -Azimuth and Golubka, which were studied according to the following field experiment scheme: control (no treatment), seed inoculation (treatment of seed with the biological preparation Rizogumin), concentration of retardant (no treatment, 0.5%, 0.75% and 1% solution). The relevance of the research is reinforced by the task of applied research on the topic: «Development of scientific and technological support for improving soil fertility and rational use of bioresources potential» (state registration number: 0124U000444).

Comprehensive assessment of sowing qualities of soybean seeds after pre-sowing treatment of seeds with biological preparations is a scientifically valuable and urgent problem of today, which made it possible to choose the optimal methods of realizing the genetic potential of productivity of modern soybean varieties. In laboratory and vegetation conditions, the sowing properties of soybean seeds were evaluated under pre-sowing seed sterilization. The aim of the research was to establish the sowing qualities of soybean seeds (varieties Slavna, Churaivna, Azymut, Tytan, Triada, Pallada, Samorodok), namely seed moisture, germination energy, field germination and linear hypocotyl parameters depending on the varietal composition and pre-sowing seed treatment with a bacterial preparation. Field and laboratory studies were conducted according to the following indicators: seed moisture, germination energy, field germination and linear hypocotyl parameters according to generally accepted methods. Research on the basis of the scientific research field of the Institute of Fodder and Agriculture of the Podillia National Academy of Sciences by the method of split plots in four repetitions according to the methodology of research in agronomy, p. Bohonyky, Vinnytsia region, Ukraine. It was established that the moisture content of the seeds of soybean varieties during 2020-2023 storage in uncontrolled climate conditions was within the normal range and did not exceed 13.4%. It was noted that the use of pre-sowing treatment of seeds with a bacterial preparation based on strains of nodule bacteria had a smaller effect on laboratory germination, and to a greater extent on the germination energy of soybean seeds. The maximum indicator was obtained on the Slavna soybean variety -93.4% for the use of nitrogen-fixing bacteria (Rhizoline+Rhizosave) in the presowing treatment of seeds. Laboratory germination had a significant tendency to increase up to 96.3-98.1% in variants with Svavna and Tytan varieties for the use of nitrogen-fixing bacteria (Rizolain+Rhizosave) in the presowing seed treatment. Based on the obtained results, in order to stimulate the germination of soybean seeds, it is proposed to bacteriize them with complex inoculants, which is a more effective measure than inoculation with a monoculture of rhizobia. In the conditions of the Right Bank Forest-Steppe, in the variants where a bacterial preparation (Rizolain+Rhizosev) was used for pre-sowing seed treatment, the mentioned technological methods of growing can be used to improve the technology of growing soybeans.

“…The amount of nitrogen, which is necessary for maintaining the growth and development of plants before being included in the process of nitrogen fixation, is small and can be provided by its soil reserves. The role of starting doses of nitrogen fertilizers, especially on poor soils, to protect plants against a possible lack of nitrogen in the event of a delay in the appearance of nodules, their slow development under adverse conditions, is not excluded (Monarkh and Pantsyreva, 2019). Considering that the presence of nitrogen in the ammonia form in plants is related to nitrogen fixation and nitrogen consumption from the soil, whereas the content of nitrate nitrogen is exclusively from mineral nutrition, a decrease in the ratio of ammonia nitrogen to nitrate indicates a decrease in the share of symbiotic nitrogen in soybean nutrition when nitrogen fertilizers are applied (Mazur et al, 2020;Choudhury et al, 2021).…”

For the successful development of the agricultural sector, one of the main tasks during the cultivation of agricultural crops is the rational use of land resources and obtaining the highest possible quality of products with low labor costs. The practical value of the scientific article lies in the improvement of the elements of the technology of growing soybean varieties that differ in groups of maturity. The development of ecological and economic technological parameters made it possible to ensure the seed yield, depending on the maturity groups of high-tech varieties, up to 2.91 t/ha with high production profitability. The object of researchinvolved the processes of growth, development and formation of the soybean seed crop, as well as its quality depending on the developed technological parameters. The subject of research comprised soybean varieties, pre-sowing treatment of seeds with a bacterial preparation and a growth regulator. It was determined that soybean belongs to the high-protein strategic agricultural crop of Ukraine and the world. Providing the population with protein food is a global problem, because the increase in population significantly exceeds the production of protein products. Soy, which is characterized by a rare chemical composition, plays an important role in solving this problem -its seeds contain 38-42% protein, 18-32% fat, 25-30% carbohydrates, enzymes, vitamins, minerals, many essential amino acids with a significant degree of solubility and nutrition. This feature has a positive effect on the environment and allows obtaining ecologically clean products. The cultivation of soybeans is of great agrotechnical importance, as it is a good precursor for the cultivation of the vast majority of agricultural crops. However, the determining factor for obtaining a high yield of soybeans is the variety. On the basis of the research results, their economic analysis and with the aim of growing high soybean yields at the level of 2.91 t/ha, the agro-forming of the right-bank forest-steppe of Ukraine recommended sowing the intensive soybean variety Sandra -carrying out pre-sowing treatment of soybean seeds with the bacterial preparation Rizotorphin in combination with the growth regulator Vermyst. Therefore, the scientific work is devoted to researching the yield and nutritional value of soybeans of different varieties depending on the inoculation of seeds with bacterial preparations and treatment with growth regulators, which is relevant as well as of scientific and practical interest in the field of ecologically oriented growing technologies.
