Abstract:

Progressive increase in doses of both pendimethalin (from 1.0 to 2.0 kg ha- ' ) and anilofos (from 0.4 to 0.8 kg ha- ' ) resulted in decreased density and dry weight of all the weeds at 60 days stage. However, both the herbicides were more effective when 2, 4-0 at 0.5 kg ha- ' or bentazon at 0.72 kg ha- ' were applied as follow up application. With follow up treatment pendimethalin at 1.0 kg ha" with 2, 4-0 at 0.5 kg ha- ' recorded highest grain yield and weed control efficiency. Among alone applications oxyfluorfen at 0.25 kg ha- ' was most effective as it was able to control both broad-leaved weeds and grasses, however, it was not as effective as herbicide combinations in obtaining grain yield.
