Corn grain is a source of total energy and nutrients for human nutrition, animals and birds. The rational use of corn grain depends on the quality, is determined by the conditions of cultivation. Therefore, in order to study the reaction of maize hybrids and the formation of high-quality grain, field and laboratory experiments are necessary. Purpose. To establish the dependence of the influence of models of corn growing technology on the level of yield, quality and nutritional value of grain. Methods. Field combined with visual, weight, physiological, biochemical, computational-comparative and statistical methods. Results. The article presents the indicators of the qualitative and nutritional composition of the grain of corn hybrids of various groups of ripeness grown in the Right-Bank Forest-Steppe with different technologies of tillage. Highlights the effectiveness of growing corn in years with different moisture availability. The influence of hydrothermal resources of the region and organized factors on the formation of the value and quality indicators of grain hybrids of maize is revealed. The variation of indicators of the chemical composition of grain of maize hybrids from specific hydrothermal growing conditions is given. The value of the yield of raw protein of the corn grain harvest with various growing technologies has been determined. Findings. Modern grain production should be based on the use of energy-saving technologies, providing for the effective use of the genetic capabilities of maize plants and will provide a high nutritional composition of the grain without the use of additional energy costs.
