Predicting the yield and quality of winter wheat grown on calcareous chernozem in the lower Don Region

摘要

Lon g - term studies have revealed a system of indicators for predicting the yield of winter wheat grown on a calcareous chernozem. It has b een established that the prediction and integrated assessment of the yield and quality of grain should be performed with consideration for the balance of macro - and micronutrients in the grain and the above - ground biomass of plants. It has been shown that the contents of protein and gluten in winter wheat grain are mainly determined by the supply of plants with nitrogen and its balance with Mn, §2, Fe, Zn, and K. 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.
