| Abstract | ||
| The current study was carried out over the course of three consecutive seasons in 2019–2020, and 2021 in a private mango orchard located in the Draw region of the Aswan governorate, where the soil is sandy. Zinc, boron, and calcium all play crucial roles. Mango tree growth and fruiting can therefore be enhanced by the balanced application and absorption of Ca, B, and Zn. to test the theory that foliar application of these nutrients in combination will improve the fruiting and vegetative growth of Keitt mango trees, a field study was carried out. Zinc, boron, and two Ca sources (Ca plus Zn and Ca plus B) in a single-state spring were investigated. 1ml/L of zinc, boron, or calcium in combination with either mineral was applied. The shoot length, leaf area, and leaf chlorophyll, as well as the yield, total soluble solids, sugar contents, panicle length, were all markedly enhanced by these treatments. The results showed that zinc and calcium worked better than other therapies. It has been determined that spraying calcium next to zinc or boron will enhance the growth and fruiting of Keitt mango trees. | ||
