Abstract
This investigation was conducted during the two consecutive seasons of 2015 and 2016 on thirty 10-years old Succary mango trees onto seedling mango rootstock. The trees are grown in a private mango orchard located at Edfu district, Aswan Governorate. The uniform in vigour trees of Succary mango (30 trees) were planted at 7 x 7 meter apart. The soil texture of the tested orchard is silty clay well drained with a water table depth not less than two meters. Surface irrigation system was followed using Nile water.
The goal of this study was examining the effect of single and combined applications of glutathione and boric acid on growth, nutritional status, yield and fruit quality of Succary mango trees grown under Aswan conditions.
The selected trees (30 tree) received the usual and common agricultural and horticultural practices that already applied in the orchard except those dealing with the present treatments (application of antioxidants and boric acid).
Under the experimental and resembling conditions, it is advise to spray Succary mango trees there times (at growth start, just after fruit setting and at one month later) with a mixture of glutathione and boric acid each at 0.05 % for promoting yield and fruit quality.
