WINTER WHEAT PRODUCTIVITY IN DEPENDENCE ON THE METHODS OF PRIMARY TILLAGE IN THE NIZHNEE POVOLZHIE

Abstract

The result of the study was an establishment of dependence of winter wheat productivity on a method of a primary tillage. There has been identified an advantage of deep chiseling on 0.35–0.37 m over moldboard plowing on 0.20–0.22 m, over disk tillage on 0.12–0.14 m and direct sowing. Plots with deep chiseling showed the best performance compared with other methods of primary tillage in density, porosity, humidity and, consequently, winter wheat productivity.
