This work was carried out in collaboration between all authors. Authors MAS and MMN designed the study, wrote the protocol, and wrote the first draft of the manuscript. Author MSES managed the literature searches, analyses of the study performed the spectroscopy analysis and author OMH managed the experimental process and author EAM identified the species of plant. All authors read and approved the final manuscript.

The present investigation was carried out during two successive seasons of 2002 and 2003 on Canino Apricot trees budded on seedlings rootstock at a private orchard located at El-Khatatba district, Menofia Governorate Egypt. Trees were sprayed at full-bloom stage with boron, GA 3 and active dry yeast at different concentration alone or in their combinations. Results showed that spraying Boron, GA 3 and active dry yeast either singly or in combination caused a remarked promotion in leaf mineral status, yield and fruit quality compared with control treatment Combined application solution of 400ppm Boric acid, 40ppm GA 3 and 2% active dry yeast at full bloom stage gave the best results with regard to the yield and fruit quality of Canino Apricot.

The effect of foliar spray with algae extract and/or potassium nitrate on the quantity and quality of Barhee date palm yields was investigated during the 2017 and 2018 seasons. Inflorescences of Barhee date palms were sprayed twice, after pollination (1st April of each season) and one month later, with algae extract at concentrations of 0.5% and 1.0% and with potassium nitrate at concentrations of 1% and 2% applied individually or in combinations. The obtained results showed that all of the sprayed treatments enhanced the yield and fruit properties when compared to the controls. Spraying inflorescences of Barhee date palms with algae extract and/or potassium nitrate had a significant effect on the yield and on the physical and chemical properties of the fruit when compared with the untreated palms. The increase in yield and qualitative properties was associated with increasing concentrations of both materials (algae extract and potassium nitrate). The best results were detected with spray containing high rates of combined treatment (1% algae extract + 2% potassium nitrate) applied twice in both seasons studied because this treatment resulted in the highest value of fruit and bunch weight, increased the yield per palm compared to the control by about 60.2%, and improved the fruit physical properties (fruit length, fruit diameter, fruit shape index, flesh weight, and seed weight) and fruit chemical properties (total soluble solids (TSS); acidity; TSS/acid ratio; tannins; and reducing, nonreducing, and total sugars) of the Barhee date palm given the experimental conditions.
