The article shows the influence of mineral fertilizers on the productivity of sunflower oilseeds in the zone of chestnut soil of Volgograd region. Mineral nutrition, along with another limiting factor water regime are the main components of yield-forming conditions in sunflower in the arid zone of Volgograd region. But new sunflower hybrids constantly appear in production, the nature of their interaction with fertilizers does not always meet the parameters of yield. Therefore, it is necessary to determine how new hybrids such as Immy and Margaret CLP respond to the use of fertilizers. It was found that the application of the calculated amount of mineral nutrition allows in the zone of chestnut soils of the north-western zone to obtain 3.2 t/ha of sunflower oilseeds using modern hybrids.
