The goal of the study was to determine the effect of crop density of middle-ripening soybean variety Sviatogor at different doses of nitrogen fertilizers on the economic and energy efficiency of its cultivation. Results of the study allowed determining that the highest profitability of 237% was provided by the variant with mineral fertilization at the dose of N30 with the density of 600 K plants per 1 ha. At the background of mineral nutrition N30 and N60, the expenditures per 1 ha decreased by 29.1-28.2%, respectively, in comparison to the unfertilized variants, which led to a significant increase in the net profit. The economic efficiency of growing the middle-ripening soybean variety Sviatogor is significantly reduced at the nutritive background of N30 and N60, in comparison to the unfertilized variants, combined with an increase in plant density per hectare from 700 to 1,000 K. The energy coefficient on the fertilized background was higher at the plant density of 600 K plants per 1 ha, and on the unfertilized one - at 500 K plants per 1 ha. We recommend cultivation of soybean variety Sviatogor in the irrigated conditions of the South of Ukraine by the agrotechnological complex with mineral nutrition of N30, plant density of 600 K per 1 ha.
