JF - ISPEC Journal of Agricultural Sciences JA - ISPECJAS VL - 5 IS - 3 SE - Articles DO - 10.46291/ISPECJASvol5iss3pp728-740 UR - https://www.ispecjournal.com/index.php/ispecjas/article/view/218 SP - 728-740 AB - <p>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 KNO<sub>3 </sub>(4.2 kg/12 tree)<sub>, </sub>K<sub>2</sub>SO<sub>4</sub> (3.7 kg/12 tree) and KNO<sub>3</sub>+K<sub>2</sub>SO<sub>4</sub> (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%, K<sub>2</sub>SO<sub>4</sub> 2.02% and KNO<sub>3</sub>+K<sub>2</sub>SO<sub>4 </sub>8.25% in KNO<sub>3</sub> 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.</p> ER -
