This study was carried out to investigate the nutritional status of the semi-stunted Starkrimson Delicious variety apple trees in the province of Van, Erciş. A total of 30 gardens were tested and leaf nutrient analyzes were performed. Physical and chemical analyzes were carried out on the soil of the experimental area and the nutrient element sufficiency levels of soil and plant were determined. According to soil analysis results, it was determined that the soil of the experimental area was sandy loom, neutral-slightly alkaline, less lime and salt-free. The contents of K, Mg, Mn, Fe, Ca and Cu are sufficient in the experimental soil, organic matter, available P and Zn contents are found to be low. According to leaf analysis results, K content is generally high and N, Ca and Zn content is inadequate. P, Mg, Fe, Mn and Cu were found to be sufficient.
