Abstract:
The experiment was carried out during three seasons (2020,2021,2022) on Al- khudairi olive trees,30 years old in Rwayst al-hersh village in Lattakia. The aim of research is to study the effect of irrigation and organic fertilization on the production and quality of fruits of Al- khudairi olive trees. Two levels of organic fertilizer 5 and 7 kg\ tree, were added in November, and irrigation water was used three times at a fixed irrigation water rate at 800 liters\ tree\irrigation. A completely randomized design was adopted. The experiment included 12 treatments and each treatment had 3 replications. The results were analyzed using Genestat 12 program by calculating the least significant difference level of 5%. The results showed that the T12 treatment (7 kg\tree organic fertilizer+ 3 irrigations) was superior to the three- year average in the amount of production of 45.54 kg\tree, with an increase rate of 88.18 % over the control , and in the average weight of the fruit 3.32 g and the average weight of the pulp of 2.7g, an incease of 45,94% over the control. Also, all the treatment that received one or two or tree irrigations wewe superior in average pulp to kernel ratio to all treatments that didn’t receive irrigation. Also, (T8, T12) were superior in average fruit size (3.1 ,3) cm3with significant differences. The size of the kernel and the percentage of purification also followed the same trend as the size of the fruit , as treatment (T12, T8) (0.486,0.48) cm3 and(2.997,2.99)% consecutirely out performed the rest treatment.
