Abstract: A field experiment was conducted during kharif, 2016-17 at Agriculture College Farm, UAS Raichur on clay loam soil with a view to find a suitable herbicide for groundnut + pigeonpea intercropping system. The lower total weed density, total weed dry weight and weed index was recorded with application of pendimethalin 38.7 % CS @ 750 g ha-1PE fb imazethapyr + imazamox 70% WG@ 70 g ha-1 (POE) at 20-25 DAS + IC at 45 DAS. Higher weed control efficiency was recorded in pendimethalin 38.7 % CS @ 750 g ha-1PE fb imazethapyr + imazamox 70% WG@ 70 g ha-1 (POE) at 20-25 DAS)+ IC at 45 DAS (47.74 %). Whereas, significantly higher plant height, total dry matter production, leaf area, leaf area index, number of pods per plant, pod weight, pod, haulm, seed, stalk, husk yield and groundnut equivalent yield was recorded with application of pendimethalin38.7 % CS @ 750 g ha-1PE fb imazethapyr + imazamox 70% WG@ 70 g ha-1 (POE) at 20-25 DAS)+ IC at 45 DAS followed by pendimethalin 38.7 % CS @ 750 g ha-1PE fb imazethapyr 10 % SL @ 75 g ha-1POE ( at 20-25 DAS)+ IC at 45 DAS.
