ABSTRACT
A field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, 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, 40 and 60 kg ha-1) and five weed management practices (weedy, weed free, hand weeding at 25 & 45 DAS, pendimethalin 1.0 kg ha-1 and pendimethalin 1.0 kg ha-1 + one hand weeding at 45 DAS) and replicated three times. The results obtain during the course of investigation indicated that the application of 60kg ha-1 phosphorus with pendimethalin 1.0 kg ha-1 + one hand weeding at 45 DAS, 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.
