Bertimoda is classified as one of the finest class dry date palm varieties in Aswan Governorate, has good taste and excellent flavour. (Hussien, 2005 and Ibrahim, 2011). In last decade a remarkable decrease in yield and fruit some quality characteristics of Bertimoda cv. under Aswan Governorate conditions were observed (Al-Bakry 2020). In order to study the response of Bentimoda palms (Phoenix dactylifera L.) to spraying abscisic acid (ABA) at 150, 300 and 450 ppm on leaves mineral content, fruit set and retention%, yield (kg/palm), and
fruit physic-chemical properties. A field experiment was conducted in two successive seasons (2018 and 2019) at a private farm located at Edfo, Aswan Governorate was take place. The obtained results confirmed that all ABA
concentrations (150, 300 and 450 ppm) used has a positive effect on leaves mineral contents (i.e. nitrogen%, phosphorus%, potassium%, iron ppm, Zinc ppm and manganese ppm), yield (kg)/tree and bunch weight (kg), as
well as fruit physical and chemical properties (i.e. fruit length (cm), fruit dimensions (cm), TSS%, total and reducing sugars%) rather than untreated ones. While, the total acidity% and crude fibers % were significantly
decreased rather than untreated palms. For all physic-chemical properties of fruit, non-significant differences were observed between the two highest concentrations (300 ppm and 450 ppm). Then, it is recommended to foliar spray
Bertimoda date palm grown under Aswan governorate conditions with ABA at 300 ppm in order to improve nutritional state, yield/palm, fruit physical and chemical properties. leaves mineral contents
