| Abstract | ||||
| This study was conducted during two successive seasons 2022 and 2023 at a private orchard located in El-Marashda region, Qena governorate, Egypt. The aim of this investigation is to evaluate the impact of amino acids, potassium silicate and citric acid spray on productivity and the fruits physicochemical characteristics of mango cv. Tommy. Mango trees were sprayed with potassium silicate or amino acids at 1.5 cm3/L and citric acid at 1 g/L thrice at the end of October, 15th February and 15th May. The results showed that yield as well as physical and chemical fruit characters was all markedly enhanced by application these treatments compared non application. Amino acids spray surpassed on the rest of the other treatments in improvement crop quantity and fruit physical characters, while spraying potassium silicate surpassed in improving fruit chemical characters with no significant differences between them. Citric acid spray ranked the last order in this respect. It is that amino acids should be spraying at 1.5 cm3/L three times in the end of October and middle of February and May to improve the yield quantity and quality of Tommy mango fruits and lessen the negative effects of heat stress. | ||||
