Аннотація: The article reveals the role of soybean varieties and the value of their crops, capable of fixing atmospheric nitrogen and being a favorable predecessor in modern crop rotations, the importance of optimizing organo-mineral nutrition, seed treatment with nitrogen-fixing and phosphate-mobilizing bacteria for improving the nitrogen-fixing capacity of soybean varieties. Development of the technology of growing soybeans with environmentally friendly elements requires scientific substantiation and adaptation to the soil and climatic conditions of a particular growing zone, as well as the research of their impact on the varietal characteristics of a crop. The research outcomes confirmed the maximum formation of the symbiotic apparatus indicators: the number and weight of soybean nodules and their intensive functioning with the formation of the highest indicators of the total and active symbiotic potential as well as the amount of biologically fixed nitrogen, it is necessary to jointly inoculate seeds with Rizoline and double application of chelated microfertilizers at microstage BBCH 12-13: Organic Balance + Azotophyte + Helprost Soybean + Liposam and at microstage BBCH 61-69: Organic Balance + Azotophyte + Helprost Boron + Liposam. At the same time, the total number of soybean nodules was formed in the Samorodok variety − 50.3, of which 36.0 pcs./plant were active, in the Amadeus variety – 55.6 and 40.0 pcs./plant. The total and active weight of soybean nodules in the Samorodok variety made up 515 and 399 mg/plant, and in the Amadeus variety – 586 and 454 mg/plant. Indicators of total and active symbiotic potential were 31.2 and 21.6 thousand kg/day per ha in the Samorodok variety, as for the Amadeus variety – 36.5 and 25.5 thousand kg/day per ha and biologically fixed nitrogen in the Samorodok variety – 119.0 kg/ha, in the Amadeus variety – 140.1 kg.
