| Abstract | ||||
| The roles of K, Ca, B, and biochar among other macro- and micronutrients are very important. Mango tree fruiting can be enhanced by applying a balanced dose of K, Ca, and B as well as using biochar as an organic fertilizer. In order to test the theory that applying these nutrients in combination would boost vegetative development and enhance the quality and productivity of Ewaise mango trees, a field investigation was carried out during three consecutive 2021, 2022 and 2023 seasons. Biochar and two sources of calcium, boron, and potassium (cal plus or zero salt). While Biochar was applied at a rate of 750 g/m2, all Ca, K, and B sources were applied at a rate of 12g or 60 ml/tree. The results showed that the shoot length, leaf area, leaf chlorophyll N, P, and K, yield, total soluble solids, and sugar levels were all markedly enhanced by these treatments. in addition, the results showed that salicylic acid, K, and B at zero salt were more effective than other treatments and controls. Furthermore, it was discovered that cal plus (Ca, K, and B) was more beneficial in improved the quality and yield, but zero salt was more effective in enhanced of the growth features. So, it is recommended that calcium or potassium should be administered in addition to boron or biochar to enhance the growth, yield, and quality of Ewaise mango trees and lessen the negative effects of abiotic stress. | ||||
