SUMMER BARLEY YIELD DEPENDING ON SOIL CULTIVATION SYSTEM

The ground for the use of resource-saving technologies is a set pattern - soils with high humus content (3.5 % or more) do not require intensive treatments for control of agro processes. They are able to maintain the optimal density for most cultivated plants (1.0, 1.24 g / cm 3) under the influence of natural factors. The Siberian scientists pay much attention to the issues of soil conservation tillage. In the North of forest-steppe zone of Siberia, resource-saving tillage systems are becoming well spread. However, attempts to transfer them from the steppe areas to forest conditions often fail and are accompanied by a significant loss of yield and gross yield of grain. Therefore, tillage system must be scientifically based and designed for specific soil and climatic conditions. Experimental data on the effect of resource-saving tillage systems on the yield of Tuleyevsky summer barley is received. A zero processing system, providing an increase in yield compared with moldboard deep cultivation by 0.58 t / ha, due to the optimum combination of water and nutrient regimes, soil fertility elements improvement is described.
