Zn deficiency is widely spread in paddy soils of Pakistan, and has negative impact of national rice production. A field experiment was conducted at the research area of the Institute of Soil and Environmental Sciences, University of Agriculture, Faisalabad to compare rice (Oryza sativa L.) yield and nutrients components i.e., nitrogen (N), phosphorus (P), potassium (K) and Zn, of paddy and straw in response to Zinc sulfate (ZnSO4.H2O), Zinc sulfate heptahydrate (ZnSO4.7H2O), Zn-ethylene diamine tetraacetate (Zn-EDTA) and zinc oxide (ZnO) as Zn sources which were either incorporated into the soil or applied as foliar spray 14 days after rice transplantation (DAT). Zn application significantly increased the Chlorophyll contents, tillers m–2, total biomass and paddy yield, as well as the Zn concentration in the grain and the straw, except P content in the paddy and straw. Zn-EDTA incorporated in soil (10.0 kg ha–1) resulted in greater values for these parameters as compared to other sources of Zn application. Among the method of Zn application, soil application resulted in higher yield, biomass, N and K contents in the grain and straw. Foliar application caused greater P concentration in both grain and straw, however, chlorophyll, K contents in paddy remained unaffected by method of Zn application. Zn-EDTA proved to be the most efficient source of Zn for rice production. Key words: Foliar application, rice, micronutrients, zinc
