Abstract

During two successive experimental seasons in the years 2019 and 2020, this study was carried out on 14-year-old fruitful mango trees of Keitt cultivars budded on Succary mango rootstock. In an orchard with sandy soil that received drip irrigation and was situated along the Cairo-Alexandria desert road, 54 kilometers from Cairo, next to the town of El-Solimania, Egypt. Trees were planted at (3 x 5 m) apart. The two factors in the factorial experiment were magnetic iron at (0, 200 and 400 g per tree and some natural antioxidant plants (ginger, cinnamon, and Roselle) at (62.5 g) of pure powder from each type foliar spray in 5 liters under ceroon net shading conditions. The specific and interaction effects of two studied factors were evaluated through determining the changes (response) exhibited in the vegetative growth (Shoot length and diameter, number of leaves per each individual shoot, trunk diameter and average leaf area as well leaf (N, P, K, Ca, Mg, Fe, Zn and Mn content). The combination of foliar spraying Roselle extract and adding 400 g/tree of magnetic iron to the soil proved to be the most effective treatment for the majority of the parameters examined in this study.
