Abstract: Reduced soil tillage farming method is more and more often used nowadays in Lithuania. This investigation was arranged in 2013 at ASU Experimental Station in order to find out the influence of reduced soil tillage on the density of spring rape crop and infestation of weed. Spring rape was grown in four field rotation in four renewals. The rotation was: 1. winter wheat; 2. corn; 3. spring barley; 4. spring rape. The scheme of soil tillage: 1. conventional ploughing (23–25 cm); 2. shallow ploughing (12–14 cm); 3. deep cultivation (12–14 cm); 4. shallow cultivation (12–14 cm); 5. direct seeding (no tillage). The density of spring rape crop and infestation of weeds were estimated. Different tillage methods had no significance when the density of spring rape crop in 3rd and 10th days of germination was measured. However, the density before harvesting was significantly lower when shallow ploughing (37.9 %) and shallow loosening (27.1 %) methods were used compared to deep ploughing. Investigation of the infestation of annual weeds demonstrates that shallow cultivated crops were infested the most, although it had no significance. Crops that were shallow loosened had significantly more perennial weeds (8,3 plants in m2)
