Abstract The mass of grains from the plant is one of the main features that determines the final productivity of soybeans. In the control (without the use of biological products), the weight of grains from one soybean plant of the Suzirria variety was 10.2 g, of the Danaia variety — 9.8 g, and of the Estafeta variety — only 7.8 g. Seed inoculation with Rhizobophyte and complex use of biological products (Rhizobophyte + Phosphoenterin + Biopolycid) increased the individual productivity of soybean plants. In particular, in the variant with seed treatment with Rhizobophyte, Phosphoenterin and Biopolycid, the weight of grains from one soybean plant of the Estafeta variety increased to 8.2 g, of the Danaia variety to 10.3 g, and of the Suzirria variety to 11.2 g. The lowest number of beans per plant of Bukovynka beans was observed in areas without seed inoculation — 9.6 pcs. Nata beans were characterized by a larger number of beans (10.0 pieces) and grains (41.9 pieces) per plant. Seed inoculation increased the number of beans and seed weight on plants of the studied varieties. Thus, with the use of Rhizoactive on crops of Bukovynka beans, 10.1 beans and 42.3 grain pieces per plant were formed, Nata variety — 10.8 beans and 46.3 grain pieces on one plant. Among the studied varieties in the variant without the use of fertilizers, the higher grain yield was in the Nata bean variety — 2.38 t/ha. The productivity of beans was significantly affected by inoculation of seeds with Rhizobophyte: grain yield of Bukovynka variety increased by 0.09 t/ha or 4 %, Nata variety — by 0.17 t/ha or 7 %. Conclusions. Suzirria soybeans provided the best yield structure. In particular, in the variant with seed treatment with Rhizobophyte, Phosphoenterin and Biopolycid, the weight of grains from one soybean plant of the Suzirria variety was 11.2 g, Danaia variety — 10.3 g, and Estafeta variety — only 8.2 g. Bacterization of seed by biological products contributed to the increase in grain productivity of soybean plants by 3–17 %. Under the conditions of the research, the Nata bean variety was more productive, forming 10.2—10.4 g of grain per plant, which was 0.2—1.2 g more than the Bukovynka bean variety.
