The article presents the results of a study on the productivity of soybean varieties with different length of the vegetation period in the conditions of the Oryol region. Studies were conducted in VNIIZBK in 2017-2018. Three soybean varieties were used in the experiment: Lanceolate, Leader-1 and Leader-10. Different varietal responses to the distribution of precipitation during the growing season are noted. With a lack of moisture, more early-ripening varieties had the advantage in the formation of the crop. With favorable water-temperature conditions, late-ripening varieties had an advantage. A comparison of application of bacterial fertilizers based on strain 634 and mineral nitrogen at a dose of 60 kilograms of nitrogen per hectare on soybeans revealed a tendency to increase yield when inoculated with nitragin. The highest yield - 2.82 t/ha (on average over 2 years) was formed by the Leader-10 variety.
