Abstract

This study was conducted on Selmy date palms (Phoenix dactylifera L.) cultivated on sandy soil in a private orchard located at 63 kilometers from Cairo-Alexandria-desert road, Egypt, during 2018 and 2019 seasons. Palms were sprayed with 0, 5, 6 and 7% of moringa aqueous leaf extract (MALE) at three hours before pollination then four and eight weeks after pollination. Palms treated with 6% MALE exhibited significantly higher fruit setting %, fruit retention %, bunch weight (g), yield/palm (kg), soluble solids %, total sugars %, reducing and non- reducing sugars % compared with the untreated palms in both seasons. Also, overall acidity was not affected by any of these treatments. It could be concluded that foliar spray of 6% MALE can be employed to enhance fruit set retention, yield/palm as kg, total soluble solids % and total sugars % of Selmy date palms.
