The article presents the results of 2019-2021 research on the effect of complex application of organomineral microfertilizers and biostimulants in pre-sowing seed treatment and leaf dressing in the phases of 3 triple leaves and budding on plant productivity and grain quality of soybean released new varieties, different type of growth and development, Zusha and Osmon in specific soil and climatic conditions. A positive effect on the increase (relative to the control variant without treatments) of the quantitative traits of the yield elements, which are in a positive correlation with productivity, was found by experiment: number of beans per plant on 4.29-13.85 and 3.86-10.67 pieces, amount of grain per plant on 11.35-28.65 and 8.48-26.96 pieces and weights of 1000 seeds on 3.17-8.37 and 1.75-4.32g respectively, in the varieties Zusha and Osmon. Under contrasting weather conditions in the years of the study, the largest increase in yield was noted as a result of pre-sowing seed treatment and one and two foliar applications, which amounted to: variety Zusha - 0.21-0.24 t/ha (6.7-7.6%), variety Osmon - 0.20-0.21 t/ha (6.3-6.6%). An increased fat content in the grain of 20.38% in the semi-determinant variety Zusha, and an increased protein content of 38.48% in the indeterminate variety Osmon were noted during pre-sowing seed treatment and two foliar top dressings of vegetative plants
