The combined influence of two doses of herbicide Avadex BW (3 and 6 l/ha) and three levels of NPK fertilization on spring barley variety 'Aramir' was studied in a pot experiment. Only with the highest NPK dose, and only during the initial stage of vegetation the herbicide showed the phytotoxicity toward barley. Avadex BW manifested no significant effect on the yields of ,grain and straw. Increasing doses of N~P brought about significant yield increases of above-ground parts during shooting stage, and of the grain and straw in the final yield. Fertilization gave much more evident qualitative changes in barley than the herbicide. The latter increased Ca content in the straw and decreased that of potassium in the straw and grain.
