Soil tillage and sowing technologies for spring barley and winter wheat

Influence of the soil tillage-sowing technologies on grain yield of spring barley and winter wheat is clarified in the researches in sod-podzolic loamy soils in Research and Study Farm of LUA "Vecauce" in 1998 - 2000. As a comparison variants of the soil tillage in spring barley are used: classical ploughing in autumn, ploughing in spring with soil pacomat and without it together with sowing, and sowing without soil reversing. It is ascertained that mineral fertilizer local usage together with sowing improves spring barley yield in research conditions. Direct sowing and preservative soil tillage reduce first costs and help to achieve the same level of grain productivity level in comparison with the classical soil tillage methods. Conventional early ploughing, late ploughing with soil pacomat and sowing without soil reversing were used as comparison variants of-oil tillage for winter wheat. The use of soil pacomat and local mineral fertilizing increased the yield of winter wheat in the research conditions. Direct sowing and preservative soil tillage gave a decrease of cost per ha and provide the same level of yield achieved with conventional soil tillage and sowing technologies.
