Technological methods for the formation of highly productive soybean agrophytocenoses in the Lower Volga region

The problem of vegetable protein production in arid conditions is considered one of the most urgent and significant. To solve this problem, the production of vegetable protein in the dry-steppe Volga region belongs to leguminous crops, including soybeans. And for this, it is necessary to improve the elements of its cultivation technology in order to obtain stable and maximum yields. In the conditions of the Saratov Right Bank, the effect of chemicals and their combinations on the yield of soybean seeds has been studied. The studies were conducted in accordance with generally accepted methods. Field experience in determining the most effective way to increase the yield of soybean varieties has shown that using an integrated approach, including plant treatment during the growing season using the following means – N15P60K60 + Panther + Reasil Hydro Mix + Reasil Amino B/Mo, allows you to achieve yield indicators of 1.79 t/ha for the Pokrovskaya variety and 2.03 t/ha for the variety Marina. The use of mineral fertilizers in a dose of N15P60K60, as well as their combination with the selective herbicide Panther, helps to increase the structural indicators of soybean varieties, while increasing the highest grain yield. Compliance with these agrotechnological operations will allow obtaining up to 2.03 t/ha of conditioned soybean seeds.
