Abstract

The seeding rates were 100 and 150 kg ha^–1 while the nitrogen levels comprised 100, 150 and 200 kg ha^–1 with five split application treatments viz. full at sowing, full with first irrigation, half at sowing and half with first irrigation, two third at sowing+one third with first irrigation and one third at sowing+One third with first irrigation+one third with second irrigation along with a basic dose of 100 kg ha^–1 each of P and K applied at sowing. The crop was planted on December 19. The highest grain yield of 3585 kg ha^–1 was obtained from plots given nitrogen full at sowing at 150 kg ha^–1 followed by 3334 kg ha^–1 in plots given nitrogen in two splits i.e., two third at sowing and one third with first irrigation. However, higher seeding rate (150 kg ha^–1 ) tended to increase grain yield ha^–1 with a nitrogen rate of 150 kg ha^–1. By contrast, grain protein contents were the highest (12.26%) in crop fertilized with 150 kg ha^–1 full at sowing and seeded at 100 kg ha^–1.
