A field scale experiment was conducted on wheat crop in entisol of Crop Research Farm Nawabganj, C. S. Azad University of Agriculture and Technology, Kanpur during 2016-17 Indo-Gangetic alluvium of Central U.P. The treatments were Control, 100% NPK (120:60:60 kg ha-1), 100% NPK+S40, 100% NPK+Zn5, 100% NPK+S40+Zn5, 125% NPK, 125% NPK+S40, 125% NPK+Zn5, 125% NPK+S40+Zn5 and 150% NPK. There were 10 treatments and 4 replications in R.B.D. In wheat, 125% NPK+S40+Zn5 gave 54.88 q ha-1 as against the respective control of 22.69 q ha-1. The yield increase was significantly higher in 125% NPK over 100% NPK and 150% NPK also gave significantly higher grain yield over 125% NPK. Addition of S to 100% NPK and 125% NPK gave significantly higher yield over the NPK levels without S. In case of 100% NPK+S the increase in yield due to S application was of the order of 25%. Similarly 125% NPK+S gave about 12% increase in yield over 125% NPK without S. Zn application to 100% NPK and 125% NPK increase the yield by 31% and 19%, respectively. When S+Zn both were applied in combination with 100% NPK and 125% NPK the magnitude of increase was 49.40% and 24.34%, respectively. Wheat protein content was also increased significantly (from 11.07 to 13.64%). The uptakes of NPK, S and Zn were also increased significantly due to different treatments. The treatment 125% NPK+S40+Zn5 gave the highest VCR 1.71 in wheat.
