This experiment entitled above was conducted during summer 2022 at AICRP on groundnut OUAT, Bhubaneswar. The experiment was laid in RBD with twelve treatments replicated thrice comprising Diclosulam 84% WDG @ 20g and 25g a.i./ha (PE) in combination with intercultivation at 25-30DAS and Quizalofop-p-ethyl 5% EC 50g a.i./ha (POE) at 18-20 DAS ; Pendimethalin 30% EC @ 1kg. a.i./ha (PE) with Quizalofop-p-ethyl 5% EC , Pendimethalin 30% EC + Imazethapyr 2% EC (Readymix) with Manual weeding at 20-25 and Quizalofop-p-ethyl 5% EC 50g a.i./ha (POE) at 18-20 DAS , Hand weeding twice at 20 and 40 DAS…mehr

The yield loss was upto 61.3% in case of weedy check , registering lowest yield among all the treatments. Diclosulam 84% WDG @ 25g a.i./ha (PE) fb intercultivation at 20-25 DAS (T4) significantly reduced the weed dry matter (22.09g/m2 ) resulting in highest weed control efficiency (93.4%) and lowest Weed index (0.7%).It also recorded significantly higher plant growth and yield attributing parameter, and recorded the highest pod yield (2290.0 kg/ha), haulm yield (4340.0 kg/ha) over others with highest net returns of (Rs.71865.0/ha) and B:C of 2.26.
