Methodological fundamentals for obtaining high quality food grain and increasing the yield of winter wheat in crop rotations of Central Chernozem Region

Abstract

The increase in the production and application of organic and mineral fertilizers, the cultivation of crops using intensive technology require the balance of the elements of productivity at the highest level. One of the leading places among them is occupied by plant nutrition. The intensive technology is characterized not only by a high level of fertilization, but also by the exact adherence to the rates, timing and methods of application. The ultimate goal of the intensive technology is not only to increase yields and improve the quality of winter wheat grain, but also to maintain or increase soil fertility. It was found that fertilizers improved the quality of wheat grain in all years of the study. Fractional application of nitrogen led to an increase in the content of protein and gluten in the grain in all the studied links of crop rotations. In increasing the yield of agricultural crops and the quality of grain, the development of scientifically substantiated crop rotations with correct alternation of crops in them in relation to specific soil and climatic conditions is by no means unimportant. Crop rotations also influence the elements of soil fertility. Changes in the structure of sown areas should be carried out taking into account the need to increase the area under high-yielding crops, both grain and row crops.
