| Abstract | ||||
| This study was carried out during two successive seasons of 2019 and 2020. To evaluate the effect of some nutrients spray on yield and fruit quality of Sewy date palm cultivar grown under El-Kharga Oasis , New Valley conditions. The experiment was set up in a complete randomized block design with ten treatments, using five replicates, bunch each. The data revealed that: - Mega phosphor, omega potas and omega cal-mag spray significantly increased the fruit retention and bunch weight compared to the untreated ones. Omega potas application was more effective compared with omega cal-mag or mega phosphor. - Spraying either mega phosphor, omega potas or omega cal-mag at any studied concentration was accompanied by improving fruit quality in terms of a significant increase in fruit weight, total soluble solids, sugars contents, NPK and beta carotene and significantly decreased in total acidity tannins and phenols compared to control. - The best results were obtained when using 4cm3/L of omega potas or 4cm3/L of omega cal-mag or 4cm3/L of mega phosphor, respectively. Also, no significant differences were found between spraying the two concentrations (2cm3 or 4cm3 of mega phosphor, omega potas and omega cal-mag. Therefore, from the results of the study, it could be concluded that must be sprayed the date bunches with 2 cm3/L of omega potas or 2cm3/L of omega cal-mag to obtain a high yield with good properties, hence, high value marketing. | ||||
