In a field experiment, comparative effect of three different methods of zinc application was studied, aimed at alleviating Zn deficiency in transplanted flood rice (cv. IRRI 6) grown in alkaline calcareous soil. Three methods were tried 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. Zinc content of soil before flowering and after harvest was increased significantly for all the methods. The yield and yield parameters increased significantly by the application of Zn by any method. Among the methods the effect of Zn was non-significant on yield components like tillers m2, spikelets panicle-1, % filled grains, 1000-grain weight and straw yield. However, soil application of Zn at the rate of 10 kg ha-1 was rated superior because it produced significantly higher paddy yield.
