Abstract

This study was conducted during 2014 and 2015 seasons to examine the effect of spraying boric acid and/or
glutathione each at (0.05 up to 0.1%) three times at monthly intervals starting from the first March, on growth, tree
nutritional status, yield and fruit quality of "Keitte" mango trees grown under sandy calcareous soil. An obvious
promotion was revealed on all growth aspects, leaves pigments and nutrients content, fruit retention%, yield and fruit
quality as affected by the tested treatments. Glutathione was appreciably superior to boric acid in this respect and using
both together was preferable than using them individually. The promising treatment was the application of boric acid
plus the antioxidant glutathione each at 0.1and 0.05%without significant differences among them. Therefore, from the
economical point of view, it is advised to use this treatment at 0.05%, to obtain acceptable yield and fruit quality of
"Keitte" mango trees grown under sandy calcareous soil.
