| Abstract | ||||
| This study was carried out on 54 trees of “Coratina” olive trees (Olea europea) during the two successive seasons of 2022 and 2023 at El Raml valley, Matrouh Governorate, Egypt. The study's objective was to find out how garlic extract and the biostimulant biomagic could enhance the quality and fruit production of the olive variety "Coratina". All the treatments were subjected to the same agricultural practice. The foliar treatments were used, tap water (T1), garlic extract 4% (T2), garlic extract 6% (T3), biomagic at 7.5 m/l (T4), biomagic at 9.5 m/l (T5), garlic extract 4% + biomagic 7.5 m/l (T6), garlic extract 4% + biomagic 9.5 m/l (T7), garlic extract 6% + biomagic 7.5 m/l (T8), and garlic extract 6%+biomagic 9.5 m/l (T9). According to the results, spraying fruit trees with garlic extract and biomagic, then each treatment's concentration alone in both seasons, had an impact on all the treatments. T9 gave the best fruit oil percentage, the lowest acidity, the highest vegetative development, and the best physical and chemical characteristics of the fruit. it improves the macro and micro elements in leaves. | ||||
