Gemlik Zeytin (Olea europaea L.) Çeşidinde Farklı Potasyumlu Gübre Uygulamalarının Besin Element İçerikleri Üzerine Etkileri

The study which was designed according to split plot, was established with 4 replications and 3 trees in each application. Between April and September, a fertilization program was prepared according to the results of soil and leaf analysis from the fertigation system, and the correlations between soil, leaf and fruit nutrient contents were examined by applying KNO3 (4.2 kg/12 tree), K2SO4 (3.7 kg/12 tree) and KNO3+K2SO4 (2+1.85 kg/12 tree) fertilizers. As a result of the research, it was determined that the Oil (FW) content increased by 4.08%, K2SO4 2.02% and KNO3+K2SO4 8.25% in KNO3 application compared to 2015 with different K fertilizer applications. It is seen that the yield and % oil amount increase with balanced and regular fertilizer application in olives.
