A field experiment was conducted to evaluate the comparative effect of Zn levels applied by different methods i.e. nursery root dipping in 1.0 % ZnSO4, 0.20 % ZnSO4 solution spray after transplanting and 10 kg Zn ha-1 by field broad cast method. A significant increase in Zn content of rice leaf before and after flowering and a significant decrease in P content of straw and paddy and starch content of paddy was recorded for alt the methods. N, K and Zn of paddy and straw and Zn contents of roots increased significantly with the application of zinc irrespective of the methods over control. Soil application of Zn was rated superior because it gave significantly higher content of N in rice paddy.
