| Abstract | ||||
| This study was conducted during three successive 2021, 2022 and 2023 seasons on a private farm in Al-Barahma – Qift district - Qena Governorate - Egypt. Aim the study to investigate the effect of potassium citrate, boron and fulvic acid on vegetative growth and fruiting of zebda mango. Seven treatments of potassium citrate, boron and fulvic-acid were used in single, double or triple forms as the control treatment. The experiment was subjected to complete randomization block, with three replicates and one tree for each. Spraying potassium, boron and fulvic-acid in single, double or triple forms caused a significant increase in shoot length, leaf area and chlorophyll content compared to the (control) treatment. - All treatments used led to increased yield and improved fruit characteristics in terms of increased fruit weight and pulp percentage, as well as its content of soluble solids, sugars and vitamin C. compared to the control An increase in the vegetative growth of trees and thus the yield and fruit characteristics was associated with the addition of a mixture of potassium, boron, and fulvic acid, followed by a mixture of potassium citrate and fulvic acid. From the results of this study, we can recommend the importance of spraying potassium citrate, boron, and fulvic acid in its triple or binary form three times during the growing season, as this leads to improving the vegetative growth of mango trees while producing a high yield with good fruit characteristics, in addition to reducing the harmful effects resulting from environmental stress. | ||||
