Abstract

This study was conducted during 2019 & 2020 seasons to dissect the impact of spraying chitosan at 200, 400, 800 and 1600 ppm on growth, yield and fruit quality of “Sakkoti” date palms grown under Aswan climatic conditions. This experiment set up in a randomized complete block design with five treatments and three replications, palm each. Spraying the palms with chitosan at 200 to 1600 ppm had an announced promotion on all aspects of growth, yield and fruit quality compared to the control treatment (water spraying). The highest values of the studied growth and fruiting traits were obtained due to use the higher concentrations of chitosan. Using chitosan at concentrations higher (1600 ppm) failed to show measurable effects compared to use 800 ppm. Then, the best results with regard to growth, yield and fruit quality of “Sakkoti” date palms were obtained due to spraying the palms four times with chitosan at 800 ppm.
