Abstract : An experiment was carried out during 2001 and 2002 seasons to study the effect of controlled irrigation on early and malformed panicles, fruit drop, yield and fruit quality of mango cv. Ewais, grown in a private farm located in Ismailia governorate, Egypt, under tube irrigation system. The experiment included 2 levels of irrigation: (a) the controlled irrigation treatment, recommended by the Central Laboratory of Agricultural Climate of Egypt; and (b) the ordinary irrigation treatment, applied by the growers in such location. Trees under irrigation treatment recorded the least values of early panicles, malformed panicles and fruit drop percentages. This treatment had the highest yield through increasing the number of mature fruits per tree and reducing the fruit drop (49%) than the ordinary irrigation treatment. It also slightly improved the fruit quality by increasing the fruit physical and chemical properties. In addition, this treatment saved the amount of irrigation water by ~47.5% compared to the ordinary irrigation.
