Integrated weed management options in Kharif groundnut

AbstractA field experiment was conducted during Kharif seasons of 2022-2024 to evaluate the integrated weed management options and identify effective and economic option in groundnut. The pre-emergence application (PE) of oxyfluorfen + pendimethalin (tank-mix) 188 + 500 g/ha followed by (fb) intercultural operation (IC) and hand weeding (HW) at 40 days after seeding (DAS) recorded the lowest weed biomass. The tallest groundnut plants and pod yield was observed with IC fb HW at 20 and 40 DAS and diclosulam + pendimethalin (tank-mix) 25.2+500 g/ha PE fb IC + HW at 40 DAS. Pendimethalin + imazethapyr (ready-mix) 800 g/ha PE and diclosulam + pendimethalin (tank-mix) 25.2 + 500 g/ha (PE) recorded higher weed management indices values. The other effective weed control options, under labour-scarce conditions, in groundnut include: IC fb HW at 20 and 40 DAS; quizalofop ethyl + imazethapyr (ready-mix) 90 g/ha and post-emergence application (PoE) propaquizafop + imazethapyr (ready-mix) 125 g/ha integrated with IC + HW at 40 DAS.
