A Horticultural Station orchard in the Shandaweel region of the Sohag Governorate, Egypt, was the site of this study, which was conducted on mature Aggezi olive cv. (16-year-old) during the 2020 and 2021 growing seasons. This research intends to determine the impact of spraying GA₃, lemongrass, and moringa leaf extract on the growth and fruiting of Aggezi olive trees, which are uniform in shape and planted in silty clay loam soil using drip irrigation systems. The results demonstrated that all spraying treatments with GA₃, lemongrass, and moringa extracts enhanced vegetative development, fruit set, yield, and fruit chemical features in comparison to the control. The best treatments comprised 4% extracts of lemongrass or moringa leaves to increase vegetative growth, fruit set, yield, and oil content. Thus, these treatments can be recommended for commercial use under similar conditions.
