Abstract
The article considered the issues of increasing the yield of winter wheat grain, depending on the method of basic tillage, application of manure and mineral fertilizers. A correlation and regression analysis of the yield of winter wheat grain from the applied agrotechnical techniques, indicators of the fertility of typical chernozem were carried out. It was found that the greatest increase in yield in the grain-grass crop rotation was due to shaft-free tillage for maximum fertilization, and in the grain-tillage with the same doses of fertilizers - with the use of minimal tillage. Linear regression equations have been calculated to predict the yield of winter wheat grain from agrotechnical techniques.
