This study was conducted to determine the nutritional status of olive cultivated land and olive plant in Muğla province in terms of boron and other elements. For this purpose, soil and leaf samples were collected from 125 gardens in Datca, Koycegiz, Milas, Ula, Seydikemer In soil sample were made texture, soil reaction, electrical conductivity, lime, organic matter, extractable boron, phosphorus, potassium, calcium, magnesium, sodium analysez. In plants samples were determined total boron, phosphorus, potassium, calcium, magnesium. The vast majority of the research area has sandy-tin and clayey-tin structure and low organic matter content. Lightly alkaline, neutral and medium acidic soils are in the salt-free class and contain about high lime. According to soil and leaf analysis results; Although all of the soil contains sufficient boron, the lack of boron in 93% of the leaves indicates that the plant does not benefit from the existing boron. It was determined that there was serious nutritional problems in terms of B, P, K. At the least, there was nutriotinal problems in terms of Ca and Mg. Also, secure correlative relationships between the amounts of nutrient in the soil and the amounts of nutrient in the leaf were obtained. Considering the results of this study conducted in Muğla province, it is understood that effective fertilization program, method and time are extremely important. High quality and high yield production in olive agriculture; balanced fertilization, addition of organic fertilizers and other technical applications.
