METHODS OF ZINC APPLICATION AND ITS EFFECT ON YIELD AND ZINC CONTENT OF RICE (Oryza sativa) AND WHEAT (Triticum vulgare)

Abstract

Maximum yield of rice was obtained with the dipping of the roots of seedling in a ZnO suspension and that of wheat by the residual effect of 50 kg/ha zinc sulphate applied in the soil to rice in the field experiments conducted for the comparison of different methods of zinc application. A significant effect of Zn fertilization was observed on the content and the uptake of zinc in two crops. The removal of zinc by straw was higher than that by the grain in case of rice, but there was a reverse trend in wheat.

Keywords: Zinc, rice and wheat yield.
