The objective of this study was to determine nutrient contents of pistachios in Southeast Anatolia Region.
Materials and Methods
In this study, 31 units were selected from three different ecological regions. In 1984-1985, one soil and two times leaves samples were taken from the selected region. The soil sample was analysed to determine physical and chemical properties whereas the leaves samples were analysed to determine micro and macro nutrient components the 2 years’ data.
Results
As a result of this study, pistachio could grown on reddish brown soil types and also loamy soil and high level lime containing soil. One part of three of the soil was shallow and only contained horizon A. The detected biggest part of the soil was found in loamy part where was saltiness and react between 8.1 and 8.7. Generally, all of the soil samples contained low level of organic materials and phosphor content while potassium and magnesium contents of the soil werefound to be enough exceptor unite 1 and 2.
The results showed wide range of P, Zn, and Fe deficiency. The amount of Ca, Mg, Cu, and B were found to be sufficient enough or high levels whereas N, K and Mn were found to be slightly at the low levels. The optimum limits of nutrient values in the leaves of pistachio grown in dry conditions were determined.
Seven times leaves samples were taken between May and September to determine the best time for taking leaves samples. The results showed that the nutrient components of the leaves were found to be more stable at the time of occurrence of spots on pistachio fruits.
