Abstract: The experiment was conducted in Randomized Block Design (RBD) with three replications comprising fifteen treatments of weed management were Imazethapyr @ 70 g ha-1 as pre plant incorporation, Imazethapyr 80 g ha-1 as pre plant incorporation, Imazethapyr @ 70 g ha-1 as pre emergence, Imazethapyr @ 80 g ha-1 as pre emergence, Imazethapyr @ 70 g ha-1 at 3-4 leaf stage, Imazethapyr @ 80 g ha-1 at 3-4 leaf stage, Imazethapyr + Imazamox (RM) @ 70 g ha-1 as pre emergence, Imazethapyr + Imazamox (RM) @ 80 g ha-1 as pre emergence, Imazethapyr + Imazamox (RM) @ 70 g ha-1 at 3-4 leaf stage, Imazethapyr + Imazamox (RM) @ 80 g ha-1 at 3-4 leaf stage, Pendimenthalin @ 1000 g ha-1 as pre emergence, Imazethapyr + Pendimenthalin (RM) @ 1000 g ha-1 as pre emergence, Hand weeding 20&40 DAS, Weed free, Weedy Check. The soil of experiment site was low in Organic Carbon and Nitrogen and medium in available Phosphorus and available Potassium and alkaline in reaction. The findings of present study revealed that chemical methods of weed control signify reduction in weed density and dry weight of weeds effectively over weedy check. Among the weed management treatments, the maxium plant height, no. Of tillers, dry matter accumulation, and yield attributes viz. No. of spikes, spikelets/spike, spike length, No. of grains/spike, Thousand grain weight, grain (1020 kg ha -1) and straw (1652 kg/ha) yield was observed with the application of Imazethapyr + Imazamox @ 80 g/ha at 3-4 leaf stage and established its superiority over rest of the herbicide. Similarly, this treatment also resulted into higher weed control efficiency, Nitrogren, Phosphorus and potassium uptake by crop, Net return and benefits: cost ratio. These values were very close to weed free treatment. The percent increase in grain and straw yield was 1020 kg, respectively over weedy check.
