The objective of the investigations was to evaluate the influence of a soil tillage system combined with differentiated cultivation depth on potato infestation. The experiment conducted in the years 2001–2003 included the three-crop rotation: potato – winter wheat – soy bean. In the ploughless soil tillage, ploughing was substituted with harrowing and cultivation practices or additionally with a cultivation set composed of spring-tine harrow and cage roller. Subject to a soil tillage system, ploughing or cultivation practices were performed at varied depth under particular plants. On the grounds of three-year investigations, it was found that simplification of cultivation consisting in plough elimination from the potato production technology and shallowing of each management practice brought about a marked increase of most dominant weed species as against the plough and deep soil tillage. The analyzed systems of soil tillage have significantly modified a weed number in a potato canopy. At the objects with ploughless tillage this characteristics value proved higher by 58,5% than in the plough one.
