Effect of different sowing rates revealed that weed densities and biomass were less in pora method as compared to broadcast method. Weed densities and biomass decreased with increase in the seed rate. The highest grain yield (5325.13 kg ha-1) was obtained from seed rate of 175 kg ha-1 and proved to be the most economical seed rate. Further results indicated that sowing methods greatly affected number of fertile tillers, number of unfertile tillers, single spike weight, straw yield whereas final plant height and length of spike were non significant. Similarly seed rates also highly significantly affected spike length, straw yield, final plant height, number of fertile tillers, number of unfertile tillers, per spike weight and grain yield.
