Abstract

Pre-mix combination of imazethapyr + pendimethalin at 1000 g/ha had maximum weed kill efficiency over alone application of herbicides applied as pre- or post-emergence. Similarly, the maximum grain yield (1.38 t/ha) was achieved with pre-mix combination of imazethapyr + pendimethalin at 1000 g/ha plot followed by its lower dose applied at 900 g/ha and both doses were found significantly superior over other herbicidal treatments. Supremacy of this treatment was proved by increment of grain yield to the tune of 63.3% over the weedy check and only 3.7% lesser than the hand weeding (20 and 40 DAS). Pre-mix combination of imazethapyr + pendimethalin also proved to be effective in improving other parameters like plants/m2, pods/plant, seed/pod and 100 seed weight (g).
