Complex of agrotechnical methods for different varieties of winter wheat

Abstract

Increasing grain production and improving its quality are of great importance for our country. A special role is given to winter wheat as a highly productive and valuable food crop, which occupies about 2 million hectares in the Central Black Earth Region. Winter wheat also occupies significant areas in Belgorod region, which, according to agroclimatic zoning, is included in the zone of unstable moisture. Under these conditions, the development and opening up resource-saving adaptive technologies for the cultivation of crops, in particular winter wheat, as the most important grain crop, which would be assessed not only by productivity, but also by the degree of anthropogenic load on ecological systems, are of particular importance. The aim of the research is to change the agrophysical and biological properties of the soil, weed infestation of crops, yield and quality of different varieties of winter wheat, depending on preceding crops, new types of fertilizers and growth regulator. In this work, for the first time for the Central Black Earth Region, the complex effect of preceding crops, new types of fertilizers and growth regulator on changes in agrophysical, biological properties of soil, yield and quality of cultivated varieties of winter wheat Maiskaya Yubileinaya and Almera was studied. A complex of agrotechnical techniques for different varieties of winter wheat, identified on the basis of the research results, based on the use of optimal preceding crops, new types of fertilizers and plant growth regulators, allows the development of energy and resource-saving technologies of the cultivated crop. The expediency of using the most adaptive for the conditions of the region combination of agricultural practices for promising varieties of winter wheat is shown.
