AN experiment trial was carried out during 2017 and 2018 seasons on Wonderful pomegranate trees about 7 years old grown in sandy soil under drip irrigation system from well at private orchard located on Cairo-Alexandria desert road (about 50 km from Cairo), Egypt. Treatments of salicylic acid (50,100 and 150 ppm), ascorbic acid (500, 750 and 1000 ppm) and tap water control were foliar sprayed twice a year i.e. at full bloom and four weeks later. Abstractly, salicylic and ascorbic acid treatments enhanced leaf characteristics, yield and fruit quality traits as well as minimized sunburned and cracked fruit percentages. Ascorbic acid treatment at 1000 ppm proved to be most efficient treatment in this respect.

A two-year trial was conducted during 2015/2016 and 2016/2017 seasons on young plants of S-700 jojoba clone grown in sandy soil under drip irrigation system from well at El-Maghara Experimental Station, Desert Research Center, North Sinai Governorate, Egypt. The experiment was laid out in randomized complete block design with split plot arrangement using three replications. The effect of foliar applicationofNPK(0,3and5gL−1)andbenzyladenine(0,100and 150 mg L−1) on vegetative growth, flowering, seed yield and wax content of S-700 jojoba clone was studied. The results showed that foliar sprays of NPK treatments in combination with benzyladenine treatments enhanced vegetative growth parameters, flower bud production and seed yield. Particularly, NPK at 5 g L−1 combined with 150 mg L−1benzyladenine proved to be most effective treatment in these respects.

Foliar applications of benzyladenine (0, 100 and 150 mg L −1) are studied as a potential way to increase production of branches for young plants of three jojoba clones (S-700, S-1300 and S-118) grown in sandy soil under drip irrigation system from well at El-Maghara Research Station, Desert Research Center, North Sinai Governorate, Egypt. Benzyladenine (BA) was applied four times a year starting on 1 st May, (2015 and 2016) with one-month intervals in both seasons. Vegetative growth parameters, flower buds production and seed yield were statistically different between clones. The total number of branches, the flower number and seed yield in three clones were significantly increased by treatment with BA. In general, a higher BA concentration resulted in highest number of branches. The increase in the production of flower buds and the yield of seed was correlated with the increase in the production of branches. Moreover, clone S-700 showed the highest positive response to foliar applications of BA.
