A field experiment was conducted during Rabi season of 2002-03 on sandy loam soils at Bapatla,Andhra Pradesh to study the effects of pre and post-emergence herbicides,alone or integrated with manual/mechanical weeding on weed pressure,productivity and economic returns of Rabi groundnut(Arachis hypogaea).Pendimethalin @ 0.75kg/ha as pre-emergence(PE)+imazethapyr@75 g/ha as post-emergence(PoE) herbicides at 21 days after sowing (DAS)+Intercultivation with wheel hoeing fallowed by hand weeding resulted in significantly higher growth attributes,yield attributes,yield and net returns over the unweeded control and was found at par withT1: Hand-weeding at 20 and 40 DAS,T7:Pendimethalin @ 0.75kg a.i./ha(PE)+Intercultivation with wheel-hoeing fallowed by hand weeding and T5:Pendimethalin@0.75kg a.i./ha(PE)+imazethapyr @ 50 g a.i./ha(PoE).
