Therefore two years experiment was carried out at choram. In order to study the effect of source, amount and methods of zinc application. Experiment had 8 fertilizer treatments. Soil application and foliar spraying of ZnSo4 and root exposure to 2% Zno suspension. Design was in a completely randomized block (RCBD) with tree replication. The results showed that in first year, zinc application increased yield significantly at 5% probability level. The highest yield was 7508 kg/ha with application of 40 kg Zn sulfate /ha in addition to foliar spraying ZnSo4 with 0.003 concentration. In the second year, fertilizer application increased yield significantly at 1% probability level. Grain yield was 3988 kg/ha in control, which increased to 6366 kg/ha with application of 40 kg Zn /ha soil application in addition to foliar spraying of znso4. Results showed that soil application of 40 kg znso4/ha plus foliar spraying of 3/1000 znso4 increases the rice yield. Keywords: Zinc, Rice (choram1), foliar spraying , fertilizer treatment
