Abstract: 

Zinc sulfate spraying of Thomson cultivars was carried out in the Research Orchard of Gorgan during the spring of 2010. The experiment was conducted in a randomized complete block factorial design including three levels of Zinc sulfate (2, 4 and 6 g/l) and control. The spraying was carried out in spring before the flower buds were open. The results indicated that the treatment of Zinc sulfate (4 g/l) has the greatest effect on the amount of fruit weight and fruit diameter on the tree. It also left the greatest impact on the concentration of Nitrogen, Phosphor, and Potassium in leaves in comparison to the control. Furthermore, there was a significantly positive correlation between the amount of Zn and Fe in Zinc sulfate spraying. A significant difference was observed in the amount of effective concentration of Zinc sulfate in all of the treatments. Zinc Sulfate generally increased the degree of yield.
