N, P and K fertilizer studies on Cedrus deodara (deodar) of different ages were under taken at different planting sites in Azad Kashmir during 1979. The effect alone or in combinations, measured for diameter and height growth and Foliar nutrient composition was recorded during 1979-82. At Sharda, the analysis of height measurements recorded in 1981 gave a significant response to NPK combined treatment whereas over all diameter and height growth from 1979--82was not affected. Also the diameter and height measurement recorded at Authmuqam during 1981and 1982 did not show any significant response to the application of fertilizers. However the height increments for the period 1979-82 were found significantly affected by NPK combined treatments due to cumulative effect over the past three years. Moreover the foliar N content increased significantly at both the sites.
