An on farm testing (OFT) was conducted in the farmer’s field of Daloda Rail village, Mandsaur district, Madhya Pradesh in kharif season of 2014, 2015 and 2016 to assess the effect of integrated weed management treatments on weed management and yield of blackgram (Vigna mungo L.). Application of imazethapyr 75 g/ha at 18 days after seeding (DAS) and hand weeding at 40 DAS gave 36.91% mean higher blackgram grain yield as compare to farmer’s practice (0.88 t/ha). Further, this treatment also resulted in significantly higher blackgram plant height, pods/plant, net return and B:C ratio as compared to all other tested treatments and significantly reduced the weed density and biomass as recorded at 45 DAS as compared to all other treatments tested.
