EFFECTS OF CALCIUM, BORON AND HUMIC ACID FOLIAR APPLICATION ON AGROMORPHOLOGICAL AND BIOCHEMICAL PROPERTIES OF POMEGRANATE TREE (Punica granatum L.) CV. SMAQULLI GROWN IN ERBIL REGION
This study was carried out on a local pomegranate variety in 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 acids, 0, 2 and 4 ml. L-1 calcium with 0 and 2 g. L-1 boron on the growth and fruit quality of pomegranate tree were studied separately and in combination on growth and fruit quality of pomegranate tree. Three rates of HA and Ca 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 (Ca and B) significantly increased most of the parameters pomegranate trees such as total seed, peel, and cortex weight, fruit weight, number of fruit per tree, yield, leaf dry weight, chlorophyll content, leaf area, the weight of 100 seed, vitamin C, calcium cortex, calcium leaf, boron cortex, boron leaf, N-P-K leaf, fruit size, length of fruit, the diameter of fruit, pH, TSS, TA and Anthocyanin. It has been observed that different concentrations of HA, Ca and B elements reduce the cracking rate of pomegranates. İntegration of foliar fertilizers led to the best results in terms of the growth and yield of to 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.
