The experiment in this study was conducted as a completely randomized block design with ten treatments and four replications. Treatments included: To- control, T1- 50g of Zn per tree as broadcast application, T2-100g Zn per tree, broadcast application, T3- 200g Zn per tree as broadcast application, T4- 50 g Zn per tree as band application, T5- 50g Zn per tree, band application, T6-100g Zn per tree as band application, T7- foliar application with concentration of 2kg ZnSO4 in 1000 lit of water, T8- foliar application with a concentration of 3kg ZnSO4 in 1000 lit. water, T9- foliar application with a concentration of 3kg ZnSO4 in 1000 lit. of water. Results of the experiment with Satsuma mandarins indicated that zinc application increases fruit yield and also leaf zinc concentration significantly with the highest yield and leaf zinc concentration coming from treatment T9. The effect of the rates and methods of application of zinc sulfate on fruit was evaluated and reported.
