Özet
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 in the orchard, foliar application as urea, potassium nitrate, borax, manganese sulfate and zinc sulfate 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 B in terms of nut weight and foliar application of K in terms of kernel ratio ranked the first row. While the yield (3.31 kg tree-1) was high in the Saruhanlı location, the shrinkage rate (17.43%) was found to be low in the high altitude Demirci location. Further, all foliar applications had positive effect on yield. The macro and micro nutrient content of kernel evaluated, there was an increase in nutrients in the second year, except for K, Ca and Mg. For the locations, it was seen that P, Fe, Cu, Zn and Mn content of kernel were significant. Values in Demirci location were higher than Saruhanli location. Also it was also revealed in interaction.
