The research proved, that the stubble catch crops may be an important component of crop rotation, particularly in case of cereal abundance in the cropping system. Ploughing down of the stubble catch-crop provides the organic matter, improves the soil condition and sanitary conditons of the crop, and as a result increases yield of subsequent crop. The stubble catch-crops play also an important role in environment protection, reducing in great extent the leaching of nutrients (mainly nitrogen) to the ground water. Among the species suitable for stubble catch-crops the Cruciferae are preferable. Pre-sowing soll tillage for that group of crops seems to be not cleared up so far.
