ABSTRACT A field experiment was conducted with 3 varieties ( Sonalika, OW 6 and UP 262 of wheat (Triticum aestivum L. emend. Fiori Paol.) and 2 levels of irrigations [2 irrigations (crown root initiation flowering stage), 3 irrigations, crown root initiation jointing flowering stage)] and 3 levels of fertilizers (80, 40 and 20 kg 60, 30, 15 kg and 40, 20, 10 kg N, P and Wha). With 3 irrigations and 80, 40 and 20 kg N, P and Klha OW 6 wheat gave the h ghest yield of 27.63 q/ ha, followed by UP 262 (25.86 qlha). W th 2 irrigations OW 6 recorded the highest yield with 80, P and Wha (23.1 9 qlha). The benefit cost ratio was the highest (1.98) for OW 6 with 3 irrigations and 80, P and Wha.
