Abstract: A field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology Kumarganj, Faizabad (U.P) during rabi season two consecutive years of 2011-12 and 2012-13. The experiment was laid out in Randomized Block Design having twenty treatment combinations consisted of four levels of phosphorus application (0, 20,40and 60 kg ha^-1) and five weed management practices (weedy, weed free, hand weeding at 25&45DAS, pendimethalin 1.0kg ha^-1 and pendimethalin 1.0kg ha^-1 + one hand weeding at 45DAS) and replicated three times. The results obtain during the course of investigation indicated that the application of 60kg ha^-1 phosphorus with Pendimethalin 1.0kg ha^-1 + One hand weeding at 45DAS, gave Significantly the lowest weed density was recorded with 60 kg P₂O₅ ha^-1 as compared with its lower doses and control at all the stages of crop growth during both the years but it was statically similar to 40 kg P₂O₅ ha^-1 during both years of study. Significantly higher Nitrogen and phosphorus uptake, more protein content over control during both the years of experimentation.
