Ak, B E | Fidan, M
This study was conducted to determine the mineral element concentrations in different parts of ‘Siirt’ pistachio trees. This research was carried on 35-year old, fruitful or unfruitful (showing alternate bearing) trees that were grafted on Pistacia vera rootstock at the Ceylanpinar State Farm near Sanliurfa, Turkey. The results of the analysis of leaf samples taken from fruitful or unfruitful trees as follow; nitrogen (N), phosphor (P), potassium (K), magnesium (Mg), calcium (Ca) contents were not sufficient; iron (Fe), copper (Cu) and manganese (Mn) contents of the samples were sufficient. Also it was determined that zinc (Zn) level is insuf- ficient in both kind of trees (fruitful and unfruitful trees). In this conditions the pistachio trees could not utilize the elements in the soil because of high level of Ca, low soil moisture content and high air temperature
