The aim of the experiments was to evaluate the effect of amidosulfuron and tribenuron-methyl used in spring barley on yield of winter rape, horse bean and sugar beet cultivated as rotation crop plants. The field experiments were conducted during two years. They were conducted at the Experimental Station of the Institute for Plant Protection at Winna Góra, and showed that amidosulfuron and tribenuron-methyl used in spring barley do not influence on yield of winter oil seed rape, horse bean and sugar beet cultivated in normal crop rotation.
