Objective
The goal of this study was to evaluate the relationship of nutrient utilisation of five standard pistachio culture varieties from the soil which were budded on three different pistachio rootstocks.
Materials and Methods
Pistacia vera L., P. khinjuk, and P. atlantica rootstocks and Kirmizi, Uzun, Halebi, Siirt and Ohadi culture varieties budded on these rootstocks were used for treatments.
Samples of leaves of varieties budded on the rootstocks were taken at the end of July and analysed to determine plant nutrient components. Phosphor content of the leaves was analysed by spectrophotometer whereas K, Ca, Mg, Fe, Zn, Mn, and Co contents were analysed by atomic absorption. The results were statistically analysed by Tukey test.
Results
The results showed that the levels of K, Mg, and Mn on the leaves of the budded varieties on Atlanticwere found to be higher than the other two rootstock leaves. The levels of P, Ca, Fe, and Cu of leaves on three rootstocks were found to be not significantly different. Nitrogen content (1.5) of leaves of Siirt varieties on the three rootstocks were found to be the highest whereas leaves of Halebi contained the lowest level of nitrogen (1.38). Nitrogen content of the other varieties was found to be between these two values.
Buttum was found to be the best for utilisation of nitrogen from the soil among the treatments and followed by Atlantic. The ability of nutrient utilisation form the soil among the rootstocks was found to be different and they reflected their ability to their budded varieties.
