Pomegranate (Punica granatum L.) is a characteristic species of the Mediterranean area whose use and culture have longstanding tradition. It is well adapted to the growth conditions in Turkey and Mediterranean countries and is frequently found growing in wild or semi wild conditions. Pomegranate is known as a drought tolerant crop, but regular irrigation is mandatory in commercial production. Water quantity applied and optimal irrigation regime depends on some factors as soil type, tree size, physiological phase of tree and potential evaporation. Irrigation frequency and quantity affect nutrient uptake of the trees. In this study leaf nutrient content of 'İzmir 1513' pomegranate was determined under different irrigation water quantities during two consecutive years. Three water quantities (0, 50 and 100% of estimated evapotranspiration by considering class A pan evaporation) were applied to trees by drip irrigation. Leaf content of potassium, iron, and copper was not affected, but nitrogen, calcium and magnesium increased with higher quantity of irrigation water in the first year. In the second year, nitrogen, phosphorus, calcium, magnesium and manganese were affected by the irrigation levels.
