Five technologies of winter rape cultivation, different in seed bed preparation and sowing, were compared in respect of crop yields and production costs. Mean yields ranged from 3.65 t/ha for no-tillage method, to 4.02 t/ha for soil tillage without ploughing. In comparison to conventional technology (control) the yield increased by 8% at tillage without ploughing, while at no-tillage method it dropped by about 1.4%. The lowest costs (27.57% control) were connected with no-tillage technology, while the respective inputs at tillage without ploughing were 39.6%. In relation to conventional cultivation seed oil content was comparable, ranging from 97.58% at no-tillage, to 101.44% at tillage without ploughing
