2 - year field experiment showed that application of 1/2 N as basal and 1/2 N as foliar spray at growth stage 3 increased grain yield of wheat by 43.2 percent compared to that obtained by applying full N (100 kg N/ha) as basal (normal practice). Foliar spray without starter N reduced the yield by 14.9 percent (1710.5 kg/ha) compared to normal practice. Foliar application of 1/2 N at growth stage 3 along with 1/2 N as basal was found to be profitable in terms of gross margin ($ 401.05) and benefit cost ratio (3.60); this treatment gave additional income of $ 160.02/ha.
