Abstract

Persian walnut is one of the most important nut crops. Appropriate Nutrition and correct application of nutrients to the soil are of the most important factors on the growth and Yield of walnuts. Nitrogen and potassium are among important elements in walnut plants’ Nutrition and optimum consumption of these elements is important economically and it has a great influence on performance of walnut plant. Factorial experiment with three levels of nitrogen (0, 200 and 400 N kg ha-1 Ammonium sulfate) and three levels of potassium (0, 150 and 300 K kg ha-1 Potassium sulfate) in a randomized complete block design with four replications was evaluated in the Bondar Hanza village, located in Kerman province. The results showed that application of Nitrogen significantly affected concentration of nitrogen, phosphorus, calcium and Micro elements (Iron, Copper, Manganese and Zinc) in the leaves. Increasing nitrogen application, a significant increase in nitrogen, phosphorus, iron, manganese, and copper and zinc concentrations in the leaves was observed, but potassium concentration decreased from 1. 3 to 1. 08 percent and calcium concentration decreased by 0. 75 percent in the leaves. Also, application of potassium had significant influence on potassium, phosphorus, calcium and manganese in the leaves. Increasing application of Potassium sulfate fertilizer, a reduction in nitrogen and calcium concentrations was observed, which shows negative interaction between these elements. Finally, it can be concluded that interaction between nitrogen and potassium on concentration of micro elements was meaningful, while it did not have significant influence on macronutrients.
