Four fertilizer combinations (60-60, 60-140, 140-60 and 140-140 kg NP/ha) were applied to three varieties of wheat; Faisalabad-83, Punjab-85 and LU-26S. Grain number per spike increased by increasing NP
levels but decreased at the highest NP level. Maximum grain numbers were obtained in the variety Faisalabad83. Grain weight, dry matter production, economic and biological yields and harvest index increased by increasing NP level up to 140-60 kg/ha but all these values decreased when NP level was increased to 140-140 kg/ha.
All these traits were found to be maximum in va
