【 摘 要 】

The use of polyelement diagnostics and regression analysis for predicting the yield of winter wheat at different stages of vegetation is considered. It has been established that the prediction and integrated assessment of grain yield and quality should be performed with consideration for the balance of macro-and micronutrients in the grain and the aboveground biomass of plants. Possibility of predicting the contents of macro-and micronutrients in wheat grain from the chemical composition of plants at the shooting stage has been revealed. Scientifically based recommendations are presented for managing the grain yield and quality of winter wheat.
