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.
