Abstract: . The article presents the results of field experiments to study the effect of foliar dressing on the yield of soybean seeds. The studies were carried out at the FSC ZBK in 2018-2020. In a field experiment on a dark gray forest heavy loamy soil, we studied the reaction of two soybean varieties (Leader-1 and Mezenka) to treatment with the highly effective inoculant Rizoform and foliar application with Ultramag combi microfertilizer and the amino acid biostimulator Biostim oilseed. The experimental design included the following options: control (without inoculation and treatment), seed dressing with Scarlet fungicide, basic treatment (Scarlet and Rizoform inoculant), basic treatment in combination with one and two foliar dressings with the studied preparations. The experiment was repeated four times. Experimental plots area – 10 m2. Sowing was carried out with a SKS-6-10 seeder in a wide-row method (row spacing - 45 cm) in the second decade of May. Seeding rate - 600 thousand viable seeds/ha. According to the results of the experiment, a positive effect of the tested preparations on the formation of the yield of soybean seeds was established. The most effective in terms of the factor of treatments was the option with the use of two foliar dressings with Ultramag combi and Biostim oleaginous at a dose of 0.5 l/ha. The increase in yield on average for the experience was 9.4% in relation to the control. According to the cultivar factor, the Leader 1 cultivar showed a higher yield - 2.87 t/ha versus 2.67 t/ha of the Mezenka cultivar. The responsiveness of the Mezenka variety to carrying out corrective dressing was higher than that of the Leader 1 variety (11.5 and 6.4%, respectively). The profitability of soybean cultivation was 83 - 106%. The economic effect when carrying out two leaf treatments amounted to 2,490 rubles for the Leader 1 variety and 4900 rubles for the Mezenka variety
