This study was carried out to determine the seasonal variations in the amount of leaf nutrient elements, and nutritional status through soil and plant analysis in Erzincan apricot (cv. Hasanbey) orchards. The seasonal variations of plant nutrient element in leaves were generally minimum starting 20 days before harvest and lasted until harvest in Erzincan. This term was found the best time in order to collect the leaf samples At the experimental site pH ranged from 0.77 to 3.16%. Leaf N contents of some orchards were found to be below normal. P content of both soil and leaves was generally insufficient. Furthermore, Ca, Mg, Zn and Cu contents of soils and leaves were generally normal, but that of Na was relatively high. On the other hand, Mn content of leaves was insufficient although its amount in soils was adequate, indicating insufficient uptake of this element.
