Abstract
Pistachio (Pistacia vera L.) is known as important nut crop in the world with high nutritional and commercial relevance. In the present study, the concentrations of selected major and trace elements (Br, Ca, Cu, Fe, K, Mg, Mn, P, Sr, and Zn) in P. vera samples as well as theirs ambient soils from two geographical Algerian sites (Djelfa and Laghouat districts) were measured. The analytical measurements were performed by means of a wavelength dispersive X–ray fluorescence spectrometer (WDXRF). Results showed that highest contents of Br, Ca, Fe, and Mg were reported in samples collected from Sidi Makhlouf (Laghouat) orchard. However, Cu concentration is higher in P. vera from Ain El Ibel (Djelfa) province. For the remaining elements namely K, Mn, P, Sr and Zn, the values are comparable between both provinces. The maximum soil contents of Cu, K, and Mn were found in Sidi Makhlouf grove. However, the highest amount of Br was detected in soil samples collected from Ain Ibel orchard. No significant difference for Ca, Fe, Mg, P, Sr, and Zn concentrations was found between both soil orchards. These data must be taken into account during fertilization of pistachio orchards, in order to prevent nutritional disorders and to enhance productivity and kernel quality.
