ABSTRACT

The post- emergence application of quizalofop ethyl @1.0 kg ha-1 at 15 DAS with one hand weeding at 25 DAS was the most effective and economical for controlling the grassy weeds in groundnut with maximum pod yield and haulm yield of 22.6 q ha-1 and 20.46 q ha-1, respectively. This treatment also minimized nitrogen, phosphorus and potash removal by weeds to a tune of 91.2, 84.1 and 89.7%, respectively over that of weedy check , resulting in better nutrient uptake by the crop. The maximum dry weed biomass at harvest was 250.3 g m-2 in weedy check followed by quizalofop ethyl @ 0.75 kg ha-1 at 25 DAS. The weed control efficiency was highest (72.3 %) in application of quizalofop ethyl @1.0 kg ha-1 with one hand weeding , which gave maximum benefit- cost ratio of 2.49 and net return of Rs.53067 ha-1 with additional income of Rs.36534
ha-1 over weedy check.
