Abstract :In Turkey, the orchards are being established with the ‘Chandler’ walnut variety in different ecologies, nowadays. Plant nutrition applications are important for optimum yield and quality in terms of growing. In this study conducted at two different altitudes insert ignore into journalissuearticles values(51 and 740 m); in the orchard, foliar application as urea insert ignore into journalissuearticles values(5 gr/L);, potassium nitrate insert ignore into journalissuearticles values(10 gr/L);, borax insert ignore into journalissuearticles values(1 gr/L);, manganese sulfate insert ignore into journalissuearticles values(2 gr/L); and zinc sulfate insert ignore into journalissuearticles values(1.5 gr/L); were sprayed for two years. Following the application, macro and micro nutrient content of kernel and fruit properties were determined. According to this, it was observed that foliar application of boron insert ignore into journalissuearticles values(B); in terms of nut weight and foliar application of potassium insert ignore into journalissuearticles values(K); in terms of kernel ratio ranked the first row. The shrinkage ratio, an important quality criterion for walnuts, was found to be low in the high altitude Demirci location insert ignore into journalissuearticles values(17.43%);. However, in the low altitude Saruhanlı location, the shrinkage ratio was reduced with foliar K application. In addition, while all foliar applications had a positive effect on yield, the highest value was measured in Saruhanlı location insert ignore into journalissuearticles values(3.31 kg tree-1);. The macro and micro nutrient content of kernel evaluated, there was an increase in nutrients in the second year, except for K, calcium insert ignore into journalissuearticles values(Ca); and magnesium insert ignore into journalissuearticles values(Mg);. Phosphorus insert ignore into journalissuearticles values(0.29 and 0.27%);, iron insert ignore into journalissuearticles values(30.64 and 6.24 ppm);, copper insert ignore into journalissuearticles values(7.64 and 11.35 ppm);, zinc insert ignore into journalissuearticles values(32.42 and 27.03 ppm); and manganese insert ignore into journalissuearticles values(25.77 and 30.05 ppm); contents of the grain were found to be significant for Demirci and Saruhanlı locations, respectively. Values in Demirci location were higher than Saruhanli location. Additionally, it was also revealed in interaction.
