Sunflower productivity depending on the level of mineral nutrition in the conditions of the Ryazan region

The article offers research on the study of mineral nutrition levels on sunflower productivity in the conditions of the Ryazan region. The objects of research are guy-brides VA-306, Samanta, Poseidon 625 variety. It was revealed that the use of mineral fertilizers in sunflower crops at a dose of N120P60K60 contributes to an increase in the basic biometric indicators of plants, which, in turn, has a positive effect on the yield of oilseeds. On average, over the years of research, 2.4-3.1 tons of oilseeds were obtained from 1 hectare. The highest productivity was observed in variants with the Poseidon 625 variety.
