Abstract

This study was carried out on a local pomegranate variety in the Smaqulli region of Northern Iraq's Arbil region in 2019-2020. The effects of foliar application of 0, 3, and 6 g. L-1 humic acid 0 and 2 g. L-1 boron, separately or in combination on growth and fruit quality of pomegranate tree. Three rates of HA with two levels of B were applied before and after the blooming stage. The experiment was arranged in (RCBD), with 3 replications. Trees were sampled at the harvesting stage and analyzed for morphology characteristics, chemical composition, and yield production. Data were analyzed by (SPSS) using variance (ANOVA) at a 5% level. Results showed that application of ( HA) with a foliar application (B) significantly increased most of the parameters of pomegranate trees such as (number of fruit per tree, yield, leaf dry weight, chlorophyll content, the weight of 100 seed, boron cortex, boron leaf, P, pH, Anthocyanin. was negatively affected by foliar fertilizers in this study. Combining foliar fertilizers was given the highest results on the growth and yield of a pomegranate tree. Pomegranate production is a significant contributor to the agricultural economy in Iraq and a significant source of income for farmers and rural communities of many provinces.
