Abstract
This study was carried out during the two successive seasons 2016 and 2017 on seven years old ’keitte’ mango trees (mangifera indica L.) budded on Succary rootstock, in a sandy soil under drip irrigation system in a private orchard located at el El-Shagaa village El-Nubaria, El-Beheira governorate, Egypt. The aim of this research was to investigate the effect of foliar application of Potassium silicate at (5, 10, 15 cm3/l) and Amino acids at (2.5, 5, 7.5 cm3/l) single or combined on growth, yield and fruit quality of ’keitte’ mango trees at two application time; the first applications time was taken place at beginning growth season in march, while the second application was after fruit set. Each tree was sprayed with 20 liters per treatment of solution using back sprayer. Sixty four trees were selected uniform as possible in growth, productivity and appearance for this study. This experiment consisted of sixteen treatments arranged in a factorial randomized complete blocks design with four replicates for each treatment and one tree for each replicate.
