The influence of soil tillage and sowing technologies on the yield of winter wheat was studied on sod podzolic loam soils in the LUA Research and Study Farms (RSF) "Vecauce" during 1998 to 2000. Classic early ploughing, late ploughing with soil pacomat and sowing without soil reversing were used as comparison variants of soil tillage for winter wheat. The use of soil pacomat and local mineral fertilization increased the yield of winter wheat under the research conditions. Direct sowing and conservation soil tillage gave a decrease of grain cost and provided the same level of yield achieved with classic soil tillage and sowing technologies.
