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, f ield 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.

Agroecological testing of soybean varieties of domestic and foreign selection was carried out during 2020-2022 on the experimental field Institute of Feed Research and Agriculture of Podillya of NAAS, which is located in the zone of the right-bank forest-steppe of Ukraine. The subject of research was domestic soybean varieties (Diadema Podillia, Tytan, Kobuko, Monada, Triada (Institute of Feed Research and Agriculture of Podillya of NAAS); Vorskla, Lehenda (National Research Center “Institute of Agriculture of the National Academy of Sciences”) and foreign (Merlin, Kardiff, Kent, Padua (SAATBAU LINZ eGen); Kioto, Kordoba, Briunensis (Semences Prograin Ink.); Senator, Alihator (Euralis Semences); Sultana (RAGT Semences) selection. All soybean varieties studied during 2020‒2022 were entered into the State Register of plant varieties suitable for distribution in Ukraine. The maximum seed yield in the zone of the right-bank forest-steppe of Ukraine was recorded in the following varieties: Triada (3.41 t/ha), Kioto (3.29 t/ha), Alihator (3.25 t/ha), Kobuko (3.19 t/ha), Monada (3.15 t/ha), Kardiff (3.06 t/ha) and Tytan (3.05 t/ha). According to the results of the analysis of the mass of 1000 seeds, its highest indicators were noted in soybean varieties: Tytan–194 g, Alihator–192 g, Kent–193 g, Sultana–200 g. According to the results of the biochemical analysis of soybean seeds, it was found that most of the studied varieties provided the content crude protein is more than 40%, while the Merlin, Alihator, Triada, Cardiff and Kent varieties had a crude protein content of 37.1-39.1%. The obtained results of the content of amino acids in soybean seeds show more noticeable indicators in the Tytan soybean variety. Thus, on the basis of a comprehensive approach to soybean productivity indicators, such varieties of domestic selection as Tytan and Kobuko, as well as foreign selection of Kioto, are recommended for agricultural production in the areas of seed production, animal feed and raw material in the selection process.
