A field experiment was conducted on groundnut (Arachis hypogaea L.) during Kharif (rainy season) 2016 at College of Agriculture, SKRAU, Bikaner (Rajasthan). The soil was loamy sand, low in organic carbon (0.08%) and available N (78 kg/ha) and medium in available P (22 kg/ha) and available K (210 kg/ha) with pH 8.3. Significantly the lowest density and dry matter of weeds and the highest haulm and pod yield were recorded with application of pendimethalin + imazethapyr (30+2) 800 g/ha(PE) followed by pendimethalin 1.0 kg/ha as PE, imazethapyr + imazamox (35:35) 70 g/ha at 20 DAS as PoE (at 3-4 leaf stage), pendimethalin + imazethapyr (30 + 2) premix 800 g/ha(PPI), imazethapyr + imazamox (35:35) 50 g/ha at 20 DAS as PoE (at 3-4 leaf stage), imazethapyr 70        g/ha at 20 DAS as PoE and pendimethalin + imazethapyr (30 + 2) 800 g/ha (Dry). Maximum net returns of  223016 /ha was realized under the weed free treatment and it was closely followed by pendimethalin + imazethapyr (30+2) 800 g/ha (PE), pendimethalin 1.0 kg/ha (PE) and pendimethalin 1.0 kg/ha (PPI) as  185045,  9177813 and  175462 /ha, respectively.
