A pot culture study was conducted to evaluate the effect of different levelsof zinc on the Zn content of leaf, soil, roots and starch content of paddy in eightdifferent calcareous soil series of D.I. Khan. Zn as ZnSO4 was applied at the rateof 0, 5, 10 and 15 kg ha-1 along with the basal doses of 120 kg N, 90 kg P2O5and 60 kg K2O ha-1. Zn contents of root, leaf before and after flowering and Zncontent of soil before flowering and after harvest increased. There was no effectof Zn on starch in paddy. Maximum Zn content of rice leaf before and afterflowering was observed with application of 15 kg Zn ha-1 in these soil series. InRamak soil series paddy had the highest starch content while it was the lowestgrown on Tikken soil series.
