Abstract: A field experiment was conducted on groundnut (Arachis hypogaea L.) during Kharif season2016 at College of Agriculture, SKRAU, Bikaner, Rajasthan (India). The experiment was laid out in a randomized block design with 12 treatments and replicated thrice. 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. Maximum plant height, dry matter accumulation, number of nodules, pods, kernels  and seed index were recorded with application of pendimethalin+imazethapyr (30+2) 800 g/ha (pre-emergence) followed by pendimethalin 1.0 kg/ha as PE, pendimethalin+imazethapyr (30 + 2) premix 800 g/ha (pre-plant incorporation-PPI), pendimethalin 1.0 kg/ha as (PPI), pendimethalin+imazethapyr (30 + 2) 800 g/ha (Dry), pendimethalin 1.0 kg/ha as (Dry), imazethapyr+imazamox (35:35) 70 g/ha as post-emergence spray (PoE) at 20 DAS (days after sowing), imazethapyr +imazamox (35:35) 50 g/ha at 20 DAS as PoE (at 3-4 leaf stage) and imazethapyr 70 g/ha as PoE at 20 DAS.

Keywords: Groundnut, Imazamox, Kharifseasion, Pendimethalin + Imazethapyr
