\u00a0 \u00a0 \u00a0 The article reflects the results of studies on the establishment of productivity and cost-effective cultivation of corn hybrids, depending on the density of standing plants and the background of mineral nutrition. It has been proved that in order to obtain the maximum yield when growing the DKS 3730 hybrid, it is necessary to form plant density at the level of 80 thousand\/ha; DKS 4764 \u2013 70 thousand; DKS 4795 \u2013 70-80 thousand\/ha. The lowest level of cost (1.93-1.98 thousand UAH\/t) was recorded in the DKS 3730 hybrid with a plant density of 80 thousand\/ha and on the DKS 4795 hybrid with a density of 70 thousand\/ha.\u00a0 \u00a0 \u00a0 \u00a0 \u00a0The conditional net income exceeded 40 thousand UAH\/ha on the variants with hybrids DKS 3730 \u2013 with a plant density of 80 thousand UAH\/ha; DKS 4764 \u2013 with a density of 70 thousand\/ha; DKS 4795 \u2013 with a density of 70-80 thousand\/ha. The maximum level of profitability \u2013 143.5% was in the DKS 3730 hybrid with a plant density of 80 thousand\/ha. The tendency to increase the value of gross output and, accordingly, production costs in proportion with the increase to nitrogen and phosphate fertilizers was established. The highest net profit in the experience at the level of 45.7 thousand UAH\/ha was obtained on the variant with the hybrid DKS 4795 with the application of fertilizers in the dose of N90<\/sub>P90<\/sub>.<\/em><\/p>\n
