Abstract

To improve quality and quantity of apple fruits, this study conducted in factorial experiment in randomized complete block design with 6 replications. Results showed that foliar application was applied only in the spring, the yield increased. The positive effect of foliar application in spring and fall on the yield increase was superior to the control, but highest yield was obtained in foliar application in the fall+spring. In spite of the increased yield through localized fertilization treatment and foliar application in the fall+spring no decrease was observed in fruit texture firmness. However, the specific weight of fruits and the TSS/TA ratio were increased. Because of the increased yield in fall+spring foliar application, the fruits diameter was decreased. The results showed that in order to avoid alternation and to increase the yield, the foliar application of nutrients will be effective in the spring, fall or both, especially for low yield gardens.
