Abstract: This research was conducted in order to determine the nutritional status of peach trees grown in Bursa region showing chlorosis in respect to N, P, K, Ca and Mg. Fourty five orchards having trees with chlorotic symptoms were chosen for this purpose. Marking three peach trees with and without chlorosis in each orchard, leaf samples were taken at two different growing stages and soil samples in early spring. As shown by leaf analysis, contents of N, P, Ca and Mg were found to be generally sufficient in green and chlorotic leaves, but the content of K was below the sufficiency level in some of the orchards. Differences among the N, P, Ca and Mg contents in both green and chlorotic leaves were found significant statistically at sampling stages.
