Abstract
This study aimed to determine the effect of foliar spraying of certain minerals on the yield and fruit quality of pomegranate trees with fewer flowers than normal. In the trees planned for flower thinning, after 50% of the flowers bloomed, they were removed by hand, assuming these flowers were damaged by biotic or abiotic agents and would eventually fall. The tested trees were subjected to the following treatments: T1- Remove the flowers + foliar spraying of complete micronutrient fertilizer (4 g/L), T2- Remove the flowers + foliar spraying of Zn as ZnSO4 (3 g/L) + K as Soloptas (3 g/L). T3- Remove the flowers + foliar spraying of Zn as ZnSO4 (3 g/L) + Soloptas fertilizer (3 g/L) + N as Urea (2 g/L). T4- The trees were allowed to flower continuously without foliar application of nutrients. T5- Flowers were removed, but foliar spraying was not done (Control). Foliar spraying was repeated four times at interval of 15 days. The results showed that the maximum yield (66.90 kg of fruit/tree) was in T4. However, the effect of foliar spraying on fruit yield/tree, number of fruit/tree, average fruit weight (g), cracked fruit (%), average aril weight was significant in trees with thinned flowers compared to control (T5). The highest and lowest increases in yield per tree due to foliar application of nutrients were in T3 and T1, respectively. Foliar spraying increased the yield in T3, T2 and T1 treatments compared to the control by 68, 64, and 53%, respectively.
