A field experiment was conducted during 2016 and 2017 seasons at a private orchard situated in Abu El-Matamir destrict, El-Behaira governorate, Egypt, to study the effect of foliar spray of 0, 2, 3 and 4% kaolin, twice or three times in June, July and August on vegetative growth, nutritional status, sunburn percentage, yield and fruit quality of" Costata" persimmon trees. The obtained results showed that, kaolin foliar application at 4% twice or three times (T 6 and T 7 ) considered the best treatments for enhance improvement nutritional status of trees. Moreover, kaolin foliar applications were effective to control fruit sunburn % as well as reducing severity percentage of sunburned fruits as compared to untreated trees. Also, Kaolin foliar application at three times was decreased leaf and fruit surface temperature especially under 3 and 4%. concentrations. In addition, kaolin treatments increased yield and improved fruit quality in terms of fruit weight, size, height, and diameter as well as fruit firmness. Kaolin foliar spray was raising fruit values of SSC%, and SSC/acid ratio compared to the control, whereas there is no significant variation among kaolin concentrations on this variables. Therefore, it could be recommended that, spraying kaolin at 4% three times in summer months, improving increasing gave the best result for improving trees nutritional status, and also it had a positive effect on preventing fruit sunburn damage and increasment yield and fruit quality of " Costata" persimmon trees.

This study was carried out during 2016 and 2017 seasons on twenty years old "Le Conte" pear trees budded on Pyrus communis rootstock, grown at El-Kanater Horticultural Research Station to investigate the effect of foliar application of Ca (NO3) 2 (1 and 2 % ) and borax (100 and 200 ppm) as individual or in combined on yield, leaf mineral content and fruit characteristics. The results obtained that, the highest fruit length, size, and diameter as well as fruit weight (g), fruit yield/ tree (kg) and fruit yield as ton/ fed. were recorded when pear tree was sprayed with 1or 2 % calcium nitrate + 100 or 200 ppm borax compared with both calcium and borax alone. Fruit firmness and acidity were increased by foliar spray of combined treatment calcium 100 or 200 ppm borax + 1 or 2 % Ca (NO 3 ) 2 compared to control. Spraying 1 or 2% Ca (NO3) 2 alone gave the highest significant value of N % for pear leaves meanwhile P % was improved significantly using 200 ppm borax + 2% Ca (NO 3 ) 2 . Also, K, Ca and Mg % were increased significantly with spraying 200 ppm borax +2 % Ca (NO 3 ) 2 . In most cases, leaf Fe and Zn contents were increased significantly by combined treatment of 100 or 200 ppm borax + 2 % Ca (NO 3 ) 2 or 100 ppm borax alone .
