On the basis of FSBEI HE Samara State Agrarian University, scientists of the Department of Plant Growing and Agriculture conducted research on the use of growth-stimulating drugs in the cultivation of soybeans, containing trace elements and amino acids. Field trial in 2019 - 2021 was planted in the crop rotation of the research laboratory "Forage". In the course of the research, it was found that by the green ripeness phase, the increase in the above-ground mass is 2893.6 - 3144.3 g/m2, the maximum value is 3120.3 and 3144.3 g/m2 when the crops are treated with Bracitrel and Vigor Flower on the crops of the variety Samer 1. In the initial phases of development, the accumulation of dry matter is slow: in the flowering phase from 166.0 to 204.2 g/m2, the best indicator on the Volma variety when using the Bracitrel preparation, and by the pod formation phase it increases significantly to 519.6 - 613 .5 g/m2. A high rate on the Volma variety, but when the crops are treated with the Vigor Flower stimulant, here, the maximum accumulation of dry matter is observed in the green ripeness phase of 1164.6 g/m2. The biological yield by varieties ranged from 1.61 to 2.47 t/ha, while the maximum yield is achieved with the use of Bracitrel: Samer 1 - 2.18 t/ha, Pripyat - 2.30 t/ha and Volma - 2.47 t/ha.
