A study was conducted to define the relationship between plant density and wheat grain yield to establish optimum seeding rates of different varieties for various regions.Five wheat varieties (Lasani-2008, Faisalabad-2008, BARS-2009, Millat-2011and Punjab-2011) were sown at five seed rates (60, 80, 100, 120 and 140 kg ha-1) in split plot design replicated four times. Data of various attributes were recorded which revealed that maximum tillers m-2 (380.35), leaf area index (5.14), grains spike-1 (72.9), 1000-grain weight (46.19 g), biological yield (10299kg ha-1), grain yield (4222.7 kg ha-1), net income (Rs. 70017), benefit cost ratio-BCR (1.80) and minimum rate of return-MRR % (180.4) were observed for the treatment Punjab-2011. The seeding rate of 120 kg ha-1 gave maximum tillers m-2(372.25), grains spike-1(69.75), leaf area index (5.06), 1000-grain weight (46.25 g), biological yield (10604 kg ha-1), grain yield (4423 kg ha-1), , net income (Rs. 76542), BCR (1.88%) and MRR % (187.93). The interactive effect ofPunjab-2011 sown at seed rate of 120 kg ha-1 exhibited maximum tillers m-2(423.30), leaf area index (5.82), grains spike-1 (77.05), 1000-grain weight (48.28 g), biological yield (11554 kg ha-1), grain yield (4876.5 kg ha-1), net income (Rs. 92217), BCR (2.06) and MRR % (205.93) suggesting that Punjab-2011 is the best variety and optimum seed rate of 120 kg ha-1 in arid agro climate of thal zone.
