Abstract:

Among the herbicide treatments, significantly lower total number of weeds (7.63, 6.12, 7.84 and 7.71 m-2 at 25, 50, 75 DAS and at harvest, respectively) and total weed dry weight (2.52, 2.79, 4.52 and 4.65 g m-2 at 25, 50, 75 DAS and at harvest, respectively) was recorded with treatment receiving Pendimethalin 30 EC + Imazethapyr 2 EC @ 1.0 kg ha-1 PE (ready mix) + manual weeding at 30 DAS. Further the same treatment recorded significantly higher pod yield (2,897 kg ha-1), kernel yield (2,076 kg ha-1), haulm yield (4,345 kg ha-1) and oil yield (952 kg ha-1) and economic returns as compared to treatment with application of pendimethalin 38.7 CS @ 1.0 kg ha-1 pre-emergence.
