Improving Productivity and fruit Quality of Barhee date Palm by Foliar Application of GA<sub>3</sub> and NAA

The field experiment was designed to evaluate tested treatments to select which suitable treatment should be recommended to be used for Barhee date palm trees grown at Alexandria desert road near El-Sadat city, Egypt. GA3 and NAA were used in concentrations (25, 50 and 75 mg.L-1) individually and the mixture of each equal doses. Experimental design was Randomized Complete Block Design (RCBD). The obtained results revealed that the treatment GA3 + NAA (75 mg.L-1) was distinguished in the yield components (Bunch weight, retained fruits, fruit weight, yield /palm) and physical properties of the fruits (fruit weight, flesh weight, fruit length and width). In addition, application of GA3 + NAA at 75 mg.L-1 showed the highest values in physical characteristics of shees fruits (shees fruit weight, length and width). However, low fruit chemical properties of seeded fruits (TSS, TSS/Acidity ratio and sugar content, carotenoids) were observed in bunches treated with GA3 + NAA at 75 mg.L-1.
