| Abstract | ||||
| The purpose of the study is to evaluate the influence of spraying algae extract, salicylic and ascorbic acids on the yield and fruit properties of Barhee date palms. This experiment was carried out during 2018 and 2019 growing seasons. The inflorescences were sprayed three times (the first at one day before pollination, the second at the beginning of Kimri stage and the third at the beginning of fruit colour break) with algae extract at 1 and 2%, salicylic acid at 500 ppm and 1000 ppm, also ascorbic acid at 500 ppm and 1000 ppm as individual applications or in combination between them. Generally, when compared to the control treatment, spraying date palm inflorescences with algae extract at 2% + salicylic acid at 1000 ppm+ ascorbic acid at 1000 ppm had a significant influence on the yield, fruit physiochemical characteristics of Barhee date palms. However, the positive effect was indirect proportional to the increment of the concentration of the three materials. Spraying Barhee date palms three times with high doses of the combined treatment (2% algae extract + 1000 ppm salicylic acid + 1000 ppm ascorbic acid) was the superior concerning yield and both fruit physical and chemical properties in the two experimental seasons of the study. | ||||
