Abstract
The increase in productivity, quality of sunflower seeds is largely dependent on the optimal doses of fertilizers and plant density in relation to a particular variety and agroclimatic conditions of the region. The aim of our research was to study the effect of the seeding rate and the background of mineral nutrition on the productivity and quality of seeds of Orenbar sunflower hybrid. The application of mineral fertilizers in a dose of N90P60K90 on average for four years ensured the formation of a crop with a planting density of 47 thousand pcs per hectare – 1.536 tons per hectare. As the seeding rate increased to 74 thousand pcs per hectare - the productivity increased by 0.376 tons per hectare and amounted to - 2.839 tons per hectare against the background of mineral fertilizers in the dose of N90P60K90. This variant had the highest oil yield – 1.463.9 kg per hectare.
