Abstract : This study was carried out during 2013 and 2014 seasons to examine the impact of different concentrations (50 & 100 & 200 ppm) and frequencies (once, twice or twice) of salicylic acid on fruiting of Sukkary mango trees. Using salicylic acid at 50 to 200 ppm once, twice or thrice considerably enhanced shoot length, leaf area, total chlorophylls, N, P and K in the leaves, yield and fruit quality rather than non-application. Increasing concentrations of salicylic from 100 to 200 ppm and frequencies from twice to thrice had negligible effect on all the investigated characters. Carrying out two sprays of salicylic acid at 100 ppm at growth start and just after fruit setting was responsible for improving yield and fruit quality of Sukkary mango trees.
