Summary. The effects of five different chemical groups of herbicides: dinitroanilines, 1, 3, 5-triazines, 1, 2, 4-triazinones, α-chloroacetamides and carbamates on N2-fixation & yield in Lupinus were compared. Cyanazine, simazine and trifluralin caused a significant increase in acetylene reduction activity (ARA), whereas the rest had no effect on ARA. Cyanazine and simazine significantly increased the grain yield and the weight of lupin seeds. The percentage of nitrogen in the seeds was significantly increased by cyanazine. An inventory of the weeds resistant to the herbicides in the treated subplots was also carried out. The dinitroaniline group mainly controlled Galium tricorne, Lolium multiflorum, Papaver rhoeas, and Avena sterilis whereas the 1, 3, 5-triazine and dinitroaniline herbicides. Carbamates and α-chloroacetamides were less effective Papaver rhoeas, Scandix pecten-veneris and Avena sterilis. Avena sterilis was controlled by both triazine and dinitro-aniline herbicides. Carbamates and α-chloroacetamides were less effective on the weeds growing with the lupinus plants.
