Abstract

Experiment was conducted at Agricultural Research Station, Kadiri to evaluate the different weed management practices in groundnut under irrigated conditions. Field study reveals that total number of weeds at 30 and 60 DAS was significantly lower with weed free check which was on par with PE application of Pendimethalin 30 EC + Imazethapyr 2 EC @ 1.0 kg a.i./ha PE (Ready mix) + Quizalofop – p-ethyl @ 50 g a.i./ha at 15-20 DAS. Among the herbicidal treatments, Highest weed control efficiency was recorded with hand weeding (T8) at 20 and 40 DAS followed by PE application of Pendimethalin 30 EC + Imazethapyr 2 EC (Ready mix) followed by Quizalofop – p-ethyl at 15-20 DAS (T4), pre emergence application of pre mix herbicide of Pendimethalin + Imazethapyr (T2) at 30 and 60 DAS respectively. Pod and haulm yields are also higher with hand weeding (T8) at 20 and 40 DAS followed by PE application of Pendimethalin 30 EC + Imazethapyr 2 EC (Ready mix) + Quizalofop – p-ethyl at 15-20 DAS (T4
