Abstract : Hindi mango trees were treated with some nutrient elements and antioxidants in form of Sowrd as a commercial product which contains K2O 25%, Mg 0.5%, Zn 0.5%, salicylic acid 25%, L-ascorbic acid 0.01%, (Riboflavin 0.01%) as foliar application. Treatments were arranged as follows: (1) Control (spraying with water only). (2) Spraying Sword at 1% once (at full bloom). (3) Spraying Sword at 1% twice (at full bloom and two weeks after fruit set). (4) Spraying Sword at 2% once (at full bloom). (5) Spraying Sword at 2% twice (at full bloom and two weeks after fruit set). Results show that, foliar application of sword had a positive effect on leaf mineral content, yield and fruit quality of Hindi mango trees. Spraying sword at 2% twice at full bloom and two weeks after fruit set is the promising treatment for increasing fruit set, reducing fruit drop, raising fruit retention, maximize the yield and improving fruit physical properties (such as fruit weight, length, circumference, peel and pulp) as well as chemical properties of mango fruits by increasing TSS and reducing acidity.
