Abstract

This study was conducted during 2019 & 2020 seasons to elucidate the impact of using potassium at 750 to 3000 ppm, calcium at 375 to 1500 ppm and micronutrients at 200 to 400 ppm in chelates form on yield and fruit quality of “Bartamoda” date palms grown under Aswan conditions. This experiment set up in a randomized complete block design with ten treatments and three replications, one palm per each. Treating the palms with these nutrients via chelated form at the previous concentrations had an announced promotion on all aspects of yield and fruit quality compared to the control treatment (water spraying). Using chelated nutrients at concentrations higher than potassium at 1500 ppm, calcium at 750 ppm and micronutrients at 200 ppm failed to show measurable effects. Then, the best results with regard to yield and fruit quality of “Bartamoda” date palms were obtained due to spraying the palms three times with potassium at 1500 ppm, calcium at 750 ppm and micronutrients at 200 ppm via chelated form.
