Research results come from a field experiment which was conducted over 2002-2004 at the Zawady Experimental Farm owned by the University of Podlasie, Siedlce (Poland). Experimental design was a split-plot arrangement of treatments in a randomized complete block with three replications (blocks). The aim of this work was to determine an impact of soil tillage methods (conventional and simplified) as well as seven weed control methods in potato stand on dry matter, starch and total protein yields. A significant impact of weed control methods and study years on tuber dry matter yield, starch yield and total protein yield was found. The highest yields of the above-mentioned characteristics were obtained in the treatment where mechanical weed control was applied prior to potato emergence, and a mixture of herbicides Plateen 41.5 WG (2.0 kg/ha) + Fusilade Forte 150 EC (2.5 cubic dm/ha) + Atpolan 80 EC 1.5 (cubic dm/ha) was used post-emergence. The lowest yields were recorded in the treatment where mechanical control was applied pre- and post-emergence
