Objective: The objective of this study was to determine effect of different zeolite doses on plant macro nutrient concentrations, fatty acid contents and fruit weights of Gemlik and Manzanillo olive cultivars.
Material and Methods: The experiment was designed as randomized plots with three replications in Gemlik and Manzanillo olive cultivars at 7x7 m spacing. Increasing doses of zeolite (0, 500, 1000, 2000 and 3000 g tree-1) were applied.
Results: In Gemlik and Manzanillo cultivars, the levels of N, P and Ca elements in the leaves were found to be at sufficient levels. Also K concentration in Z3 and Z4 applicatins, and Mg concentrations in Z2, Z3 and Z4 applications were found to be sufficient.
Conclusion: In general, fatty acid levels varied according to zeolite applications; the order followed: oleic acid > palmitic acid > linoleic acid > stearic acid. Gemlik and Manzanillo were included in the high class category according to their fruit weight. The Z4 dose (3000 g tree-1) was more effective in applications.

Amaç: Bu araştırma, farklı zeolit dozlarının Gemlik ve Manzanilla zeytin çeşitlerinde makro besin elementi konsantrasyonları, yağ asidi içerikleri ile meyve ağırlıkları üzerindeki etkisini incelemek için yapılmıştır.
Materyal ve Yöntem: Deneme Gemlik ve Manzanilla zeytin çeşitlerinde 7x7 m aralıklarda ve tesadüf parselleri deneme desenine göre üç tekerrürlü olarak kurulmuştur. Artan dozlarda zeolit (0, 500, 1000, 2000 ve 3000 g ağaç-1) uygulanmıştır.
Araştırma Bulguları: Gemlik ve Manzalina çeşitlerinde yapraklardaki N, P ve Ca elementlerinin seviyeleri yeterli düzeyde bulunmuştur. Ayrıca, K konsantrasyonu Z3 ve Z4 uygulamalarında, Mg konsantrasyonu ise Z2, Z3 ve Z4 uygulamalarında yeterli bulunmuştur.
Sonuç: Genel olarak zeolit uygulamalarına göre yağ asidi farklılık göstermiş olup; oleik asit > palmitik asit > linoleik asit > stearik asit sırasını izlemiştir. Gemlik ve Manzanillo meyve ağırlıklarına göre yüksek sınıf kategorisi içerisinde yer almıştır. Uygulamalar içerisinde Z4 dozu (3000 g tree-1) daha etkin olmuştur..
