The individual interaction effects of irrigation and mineral nutrition applications were assessed on mango fruit development, yield, and some postharvest qualities to establish the best rate of irrigation and mineral nutrition on the yield performance and postharvest qualities. Twenty-year-old trees in Dasol, Pangasinan [Philippines] were subjected to three irrigation schedules with water applied at 27 and 40 days after flower induction (DAFI). Three kinds of fertilizers were also applied at the rate of 2 tbsp/16 L of water. Findings showed that the number of fruitlets/panicle, percentage fruit retention, yield, and dry matter yield were affected significantly by the irrigation and nutrition regimes. Trees supplied with water at a rate of 200 L/tree plus the application of CaCO3 had higher number of fruitlets/panicle compared with those of the other treatment combinations. Results also showed that trees fertilized with MgSO4 had higher fruit retention percentage, highest number of fruits, and yield/tree. Significant interaction was noted between irrigation regimes and minerals on dry matter but no significant interactions were noted on titratable acidity (TA), pH, viscosity, and juice content
