Abstract: Longer of growth period from germination to maturity in case of 10th November sown plants is probably contributed to higher grain yield and biological yield even compensating the highest lodging as result of maximum: plant height, productive tillers m-2 grain spike-1 spikelets spike-1 1000 grain weight. Various seed rate had significantly affected all the characters except days to maturity and 1000 grains weight, Seed rate of 200 kg ha-1 with intermediate productive tillers m-2, lowest grain spike-1and lowest spikelets spike-1, having maximum plant height and maximum lodging and resultantly lower grain yield, but highest biological yield. Seed rate of 150 kg ha-1 showed superiority in grains yield over others mainly because of highest productive tillers m-2, although its grain spike-1 or 1000 grain were not highest. Its plant height, lodging% spikelets spike-1 and 1000 grains were at par with the seed rate of 100 kg ha-1. Variety inquilab-91 took maximum days to maturity, grained maximum height, maximum 1000-grain weight, maximum lodging, but lowest grains spike-1, although its grains yield and biological yield were at par with Bakhtawar-92. Date of sowing and seed rate (DxS) interaction showed that productive tillers m-2 and grains yield were highest at seed rate of 150 kg ha-1, shown on 10th November. Maximum plant height and lodging were recorded at the seed rate of 200 ka ha-1 seeded on 10th November.
