Concentrations of elements (P, K, S, Ca, Mg, Si, Cl, Fe, Zn, Cu, Mn, Mo, Na, Al, Ti, Ni, Ba, As, Br, Rb and Sr) of wheat, sunflower, chickpea and lentil cultivars grown in low and high phosphorus soil were investigated by polarized energy dispersive X-ray fluorescence (PEDXRF). The phosphorus treatment x cultivars interaction was significant for the growth and element concentrations, and cultivars within plant species differed considerably with respect to element concentrations as the result of P fertilization. Shoot growth of the cultivars of each plant species was increased in response to phosphorus fertilization. Application of P increased the P concentrations of wheat, sunflower, chickpea and lentil cultivars. Under high P conditions, mean K concentrations of wheat and sunflower cultivars were decreased while the mean K concentrations of chickpea and lentil were increased. With the exception of sunflower cultivars, applied P significantly increased S concentration of the cultivars of wheat, chickpea and lentil. Calcium concentrations of wheat and sunflower cultivars were reduced by P fertilization and that of chickpea and lentil were increased. Applied P decreased mean Mg concentrations in sunflower, increased in chickpea and lentil cultivars and showed no effects on the wheat cultivars. Applied P significantly decreased mean Si concentrations of wheat and sunflower while mean Si concentrations of the chickpea and lentil cultivars were increased. Chloride concentrations of the wheat and sunflower cultivars were decreased and those of the chickpea and lentil cultivars were increased by applied P. In general, Fe concentrations of the wheat and chickpea cultivars were significantly increased by applied P. Zinc and Cu concentrations of all the cultivars of the four plant species were reduced by P, particularly Zn concentrations. However, applied P increased mean Mn concentrations of wheat and chickpea and decreased those of chickpea cultivars. Mean Mo concentrations of wheat and chickpea increased but decreased in sunflower and lentil cultivars. In general, applied P increased mean Na concentration of wheat and decreased that of chickpea and lentil. Aluminum concentrations of wheat and chickpea cultivars were decreased by applied P. Applied P decreased Ti concentrations of wheat and sunflower cultivars and increased Ti concentrations of chickpea and lentil. Nickel concentrations of wheat and chickpea were increased and those of sunflower and lentil were decreased by applied P. Applied P reduced the Ba and increased As and Rb concentrations of all the cultivars within the plant species. Bromine concentrations of wheat and lentil were decreased and those of sunflower and chickpea were increased by applied P. Finally, Sr concentrations in wheat and sunflower cultivars were reduced, and increased in chickpea cultivars with applied P. © 2009 John Wiley & Sons, Ltd.
