Abstract

This experiment was carried out during two seasons (2022 and 2023) to examine the effect of spraying pomegranate trees cv. H116 with extract algae at (2cm/l), salicylic acid at (0.5 g/l) and ascorbic acid at (0.5 g/l) either alone or in combination together on productivity, fruit properties and leaf mineral content. All treatments were applied as a foliar three times: at full blooming, after fruit sit and after 30 days from fruit set. The results showed that all treatments caused a significant increase in the yield and the leaf mineral content of trees compared to the control. Treated pomegranate trees with 0.5 g/l ascorbic acid + 0.5 g/l salicylic acid was the best treatment for enhancing the yield (kg), fruit weight (g) and fruit peel (%). Foliar l application on pomegranate trees with (2 cm/l algae extract + 0.5 g/l ascorbic acid + 0.5 g/l salicylic acid) was the best treatment in this study to improve the fruit juice content and its quality and obtain maximum leaf content of nitrogen, phosphorus and potassium.
