Abstract

Compared to the untreated control the use fo various herbicides has given yield increases of 6 11 tons per hectare. Prometryne (Gesagard 50) and terbutryne (Igran 50) gave highly significant differences in results compared to the untreated control. The effects of various chemicals, however, did not differ from each other significantly. On the average, the best weed control and highest yield increases were obtained with linuron, followed by terbutryne and prometryn. Results of MCPA and cyanazine were not as good. Prometryne and cyanazine did not have an equally good effect on weeds, and probably for this reason, they did not give good yield results consistently.
