Abstract

Assessing nutritional status of plants is the effective approach in diagnosing and determining macro and micro elements optimum patterns and increasing the yield and improving the quality of agricultural products. Therefore, this study had been done for evaluating nutritional status, seasonal variations and concentration of nutrients in leaves of five pistachio cultivars (Qazvini, Badami Zodras, Momtaz, Ahmad Aghaii and Kalle Gochi). This study was carried out in completely randomized block design a few years with three replications at Mahneshan research station. Results showed that the most Nitrogen and Phosphorous concentrations were in the fruit set stage and the concentration of these elements was decreased until kernel filling stage. Potassium concentration of leaves had not so many variations in the fruit set and fruit development stages and was decreased in the kernel filling stage. The highest concentration of Zinc was observed in the fruit set stage and then decreased. Results of the Deviation from Optimum Percentage revealed that the nutritional importance order was as K>P>Zn>B>Mn>Cu>N. Σ DOP of 450 for the Badami Zodras cultivar was the worst unbalanced nutritional estate among all cultivars and the Potassium and Boron concentrations of this cultivar was less than the optimum levels.
