Optimization of sunflower hybrids performance with the use of various doses of mineral fertilizers on the rice pads of Kalmykia

In the issue of increasing yield of sunflower seeds, the correct selection of hybrids in relation to specific soil and climatic conditions is of great concern. Each hybrid under study has its own productivity potential determined by its genotypic features. The soil and climate conditions of the Republic of Kalmykia allow to obtain 0.98...1.71 tons of hybrid sunflower seeds per hectare in terms of residual moisture after rice (280-300mm) with the correct combination of basic agricultural techniques. It is detected that there are patters of the influence of various doses of mineral fertilizers on the growth, development and formation of sunflower seed yield are established
