The influence of mineral fertilizer rates and various methods of treatment with a complex of Microfol Combi microelements on the formation of yield of soybean grain of cultivars of different maturity groups has been investigated. The authors have made the energy analysis and determined that the most effective is the model of technology of cultivating soybean of both Horlytzia and Vinnychanka cultivars, which involves the application of mineral fertilizers at the rate of N30Р60К60, presowing seed treatment with a complex of Microfol Combi microelements (150 g/ton), along with top dressing with the same preparation at the rate of 0.5 kg/ha at the budding stage that provides for the highest indicator of the energy sowing coefficient amounting to 2.53 for the cultivar of Horlytzia and 2.75 for the cultivar of Vinnychanka, that is, respectively, 0.89 and 0.99 more than check.
