Zinc Nutrition of Pistachio: Interaction of Zinc with Other Trace Elements

摘要

The antagonistic effect of zinc (Zn) with other micronutrients was studied in a calcareous soil under greenhouse conditions. Three levels of Zn were applied to pistachio seedlings along with other essential plant nutrients. It was observed that Zn application had an adverse effect on iron (Fe) concentration in plants. Zinc-deficient plants had significantly greater concentrations of Fe. The results indicated that as the Zn concentration in the substrate was increased, the Fe concentration in plants decreased. Zinc also antagonized the uptake of manganese (Mn) and copper (Cu) in the plants. The roots always showed greater concentrations of these elements than shoots.
