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 plus one third with first -irrigation and one third at sowing plus one third with first irrigation plus 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 @ 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 N ha-1 full at sowing and seeded @ 100 kg ha-1.
