Methods of tilling under conditions of insufficient and unstable moistening during winter wheat cultivation

Abstract

Acute deficit of soil moisture during the growing season of crops negatively affects the yield. Various tillage methods that are part of the technology (traditional and zero) of winter wheat cultivation affect the soil structure in the topsoil, forming the soil structure in such a way that it acquires the properties of accumulation and preservation of atmospheric moisture. Purpose of the study is to determine the method of soil cultivation that contributes into increase in winter wheat productivity and moisture preservation in the soil. The study of various tillage methods was carried out under the conditions of many years of stationary experience in leguminous crop rotation. Soil and climatic conditions over the years of research were taken into account. The researched processing methods that form the basis of the traditional cultivation technology and implement their tillage tools are: surface - disc harrow B7T; small combined unit KUM 4; dump plow PN5-35. And cultivation of winter wheat by seeder of direct sowing WINTERSTEIGER Plotseed according to zero technology was studied, i.e. the main tillage was absent.
