Abstract
An experiment to investigate the effect of 0-0-0, 50-50-0, 75-50:P, 100-50-0, 125-50-0 and 125-50-50 kg NPK ha treatments on the growth and grain yield of wheat varieties Pak-81 and Pb-85 was conducted during 1986-87. All the NPK levels significantly affected the number of fertile tillers, plant height, 1000-grain weight and grain and straw yields of both the -I varieties. The highest grain yielfs of 42.6 q ha in var. Pak-81 and 40.8 q ha - in var. Pb-85 were _~ecorded with the application of 125-50-50 kg NPK ha
