| Abstract | ||
| The present study was conducted during the two consecutive seasons of 2020 and 2021 in a private mango orchard situated at Ballana, Aswan governorate Among various macro and micronutrients. Therefore, balanced application and uptake of K, Ca, B, Zn and Mo can improve the quality and yield of mango trees. So, a field study was conducted with the hypothesis that combined application of these nutrients would be effective to increase the vegetative growth and improve yield and quality of Keitt Mango trees. Two sources of Ca (Ca plus Zn & Ca plus B) and of K (K plus citric & K plus S) and molybdenum (Mo) spring were studied. All Ca, K and Mo (where B and Z) sources were applied at the rate of 1.5 ml/L. These treatments significantly improved the shoot length, leaf area and leaf chlorophyll, N, P, K and Ca as well as panicle length and number /tree, fruit retention, yield, total soluble solids and sugar contents. Data indicated that Ca plus Zn and K-citrate were effective than other treatment and control. Moreover, Ca plus Zn was found more effective in growth traits, while K-citrate was found more efficacious of quality and yield of Keitt mango trees. It is concluded that to improve the growth, yield and quality of Keitt Mango trees would to spray calcium or potassium beside zinc and boron or molybdenum. | ||
