A series of field experiments were conducted to determine the influence of different seed rates (100, 125 and 150 kg ha-1) on yield contributing traits of promising wheat varieties viz. Sarsabz, Kiran-95 and TD-1. The maximum germination, spike length and grains spike-1 was observed under seed rate of 125 kg ha-1. The maximum plant population was recorded under seed rate of 150 kg ha-1 in Kiran-95 and highest grain weight spike-1 was noted under seed rate of 100 kg ha-1 in TD-1 variety. While maximum plant height was observed in Sarsabz under seed rate of 125 kg ha-1. The maximum 1000 grain weight was observed under seed rate of 100 kg ha-1 in TD-1; however, highest grain yield was recorded in Kiran-95. The studies about the biological yield revealed that Sarsabz indicated maximum biological yield under seed rate of 125 kg ha-1 and harvest index in TD-1 under seed rate of 150 kg ha-1. Based on the findings, it is concluded that the Kiran-95 at the seed rate of 125 kg ha-1 performed best, followed by TD-1 and Sarsabz which also produced more yield at seed rate of 125 kg ha-1.
