Abstract: Field experiments were conducted in 2009 and 2010 at the Experimental Station of Lithuanian University of Agriculture. Soil - Calc(ar)i-Endohypogleyic Luvisol. The objective of these investigations was to determine the effect of crop density and fertilization on spring oilseed rape (Brassica napus L.) 'Sponsor' weediness. In 2009 in spring rape without fertilization with the increasing number of plants to 250 per m"2, the dry matter weight of weeds decreased but not significant differences were established. At a rape crop density of 250.1-450 plants m"2, in comparison with the thinnest crop, a significant decrease of dry matter weight of weeds from 68.1 to 80.5% was observed. In rape with fertilization crop density had no significant effect on dry matter weight of weeds. In 2001 the dry matter weight of weeds depended on meteorological conditions. Intensive fertilization of rape crop, in comparison with that without fertilization, increased the dry matter weight of weeds
