Abstract
An increase in the export potential of the Stavropol Krai is impossible without increasing the productivity of the winter wheat, which is the leading crop. Our research is aimed at optimizing the nutrition of winter wheat in order to increase productivity and quality by introducing advanced developments of the chemical company “EuroChem.” As part of the tasks, we tested nutritional schemes using biomodified forms of fertilizers, as well as innovative forms of nitrogen fertilizers that contribute to the achievement of the planned indicators. As our studies showed, the highest productivity was formed on the options using biomodified ammophos 80–100 kg/ha for sowing and ammonium nitrate for top dressing, as well as on the option using UTEC carbamide 5.53–5.73 t/ha. The best indicators of economic efficiency among all the options were ensured by the introduction of 80 kg/ha of biomodified ammophos during sowing and ammonium nitrate twice in top dressing, at which the level of profitability was 136.3%.
