摘要：

Influence of the soil tillage-sowing technologies on the yield of spring barley 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 are used: classical ploughing in fall, ploughing in spring with soil pacomat and without it together with sowing, and sowing without soil reversing. It is ascertained that chemical fertilizer local usage together with sowing improves spring barley yield in research conditions in the summertime. Direct sowing and preservative soil tillage reduce first costs Ls ha(-1) and help to achieve the same level of grain productivity level in comparison with the classical soil tillage methods.
