The purpose of this work was to determine the influence of conventional and ploughless tillage systems up on infestation in two differentiated fertilization and plant protection levels on light soil. Before harvest winter rye there was determined weed infestation of square-frame method. There were estimated weed species composition and air dry matter of weeds in two randomly selected place. Number of monocotyledonous weeds, total weeds and dry matter of weeds was higher on the objects with ploughless tillage system compared with conventional tillage. Intensive fertilization and plant protection decreased number of dicotyledonous weeds in canopy of winter rye. Conventional tillage system decreased Apera spica-venti occurrence in a canopy of winter rye and increased number of Plantago major plants. Intensive level of fertilization and plant protection decreased weed infestation first of all through Matricaria maritima
