Abstract: A field experiment was conducted during Kharif 2018-19 and 2019-20 at Bagushala farmers field (odisha, India) to find out most efficientmethod of weed control in kharif maize. The treatments comprised of intercropping of maize + cowpea, maize + cowpea with pre-emergence application of pendimethalin @ 1 kg ha-1, pre emergence application of atrazine @ 1 kg ha-1 either alone or with hand weeding at 30 days after sowing, pre emergence application of atrazine @ 0.5 kg + pendimethalin @ 0.5 kg ha-1 + hand weeding at 30 DAS, hand weeding at 15 DAS and hand weeding at 15 and 30 Das were compared with unweeded control.The results revealed that growth of maize in terms of plant height, leaf area index and crop growth rate were remarkably augmented in maize + cowpea + pendimethalin followed by atrazine + pendimethalin + hand weeding, atrazine + hand weeding and twice hand weeding treatments which were at par. The maximum maize grain yield of 63.25 q ha-1 and stover yield of 79.15 q ha-1 were recorded in atrazine + pendimethalin + hand weeding practice.
