This study was established to investigate the effects of Ca application on fruit mineral nutrients, quality, and browning of ‘Fuyu’ sweet persimmon (Diospyros kaki). Ca foliar application at 40㎖/20L/tree had a greater fruit Ca concentration than did control, Ca fertigation (40㎖/20L/tree), and Ca foliar application (40㎖/20L/tree) coupled with IBA fertigation (40 ㎖/20L/tree). Fruit mineral nutrient concentrations for Mg, B, and Mn were similar or lower in the foliar treatment compared to other treatments. Fruit color was not affected. Ca treatment, whether foliar applied or fertigated, was effective in maintaining fruit firmness and in decreasing the browning symptom in fruit after MA storage at 0℃ for 60 and 100 days. Although Ca foliar application + IBA fertigation treatment improved fruit firmness, the positive effect on the browning and decay occurrences in fruit was not shown.
