This experiment was carried out during two successive winter seasons of 2016/2017 and 2017/2018 at a Private Farm of El-Salhia El-Gadeeda, Sharkia Governorate, Egypt and Post-Harvest Lab. Hort. Dept., Fac. Agric., Zagazig University, to study the effect of foliar spray preharvest with calcium (as Fertoll calcium 12%) at 1, 2 and 3%, Zn EDATA as Micronate Zn 15% at 0.5, 1 and 1.5 g/l, Chitosan at 1, 2 and 3% as well as spraying with water on yield, fruit quality and storability of strawberry under sandy soil conditions. Spraying with Zn EDTA as Micronate at 1.5 g/l four times at 75, 90, 105 and 120 days after transplanting increased yield/ plant, average fruit weight and total yield/ fad., and the increases in the total yield (%) as average three concentrations of Ca as Fertoll, Zn EDTA as Micronate and Chitosan were about 16.25 and 15.51, 17.36 and 17.19 and 16.59 and 16.47% than unsprayed in the 1st and 2nd seasons, respectively. Spraying strawberry plants with chitosan at 3% increased total soluble solids (TSS), TSS/acid ratio and fruit firmness and decreased total acidity and pH in fruits compared to water (control) in both seasons. While spraying with Zn EDTA at 1 g/l increased vitamin C content in fruits. Spraying with Ca as Fertoll at 3 ml/l decreased weight loss and decay (%) in strawberry fruits, followed by spraying with chitosan at 3% at 16 days of storage plus shelf life in both seasons. Conclusively: Spraying plants with Zn EDTA as Micronate at 1.5 g/l increased yield, average fruit weight, total yield /fad., vitamin C; spraying chitosan at 3% increased TSS, TSS/acid ratio and fruit firmness and decreased total acidity, and pH in fruits, as well as, spraying Ca at 3 ml/l as Fertoll calcium 12% decreased weight loss and decay (%) in strawberry fruits.
Key words: Strawberry, calcium, Zn EDTA, Chitosan, yield, storability.
