Abstract. In the Republic of Adygea, on leached drained chernozems, studies were conducted (2021–2023) on the effect of foliar feeding with microfertilizers containing boron and molybdenum on the growth, development and yield of soybeans, as well as on the quality of the resulting products. The purpose of this experiment was to study the effect of different doses of foliar feeding on the productivity and quality of soybean seeds. Soil cultivation with a layer turnover of 25–27 cm was used. Soybean plants (Mentor variety) were treated with boron (B) and molybdenum (Mo) in the early flowering phase, at a dosage of B 300; 900 mg / ha, Mo 100; 300 mg / ha. As a result, it was found that foliar treatment in the early flowering phase increased the yield by 9.4–30.7 % compared to the control variant. Foliar feeding had a positive effect on the formation of the best physical indicators of soybean grain quality in the variants with a triple dose of boron and molybdenum. The thousand-seed weight exceeded the control by 7.2 and 6.1 % in the variants with a three-fold increase in the dosage of boron and molybdenum, respectively. The protein content fluctuated depending on the experimental variants from 25.10 to 25.55 %, the oil content in the samples varied within 24.4–24.5 %. Treatment with the highest doses of B and Mo contributed to an increase in net income: 54.0 and 51.3 thousand rubles per hectare, respectively. The level of profitability of production in the experimental variants was 86.0 – 125.8 %. Over three years of research, recommendations were developed for the use of various doses of microfertilizers, for soil cultivation with layer turnover, which ensured an increase in soybean yield by 10 – 31 % and the quality of the resulting products by 5–10 %.
