Abstract To study the response of date palm trees to Fe fertilization, two date palm cultivars, Khlas and Ruzaiz, were fertilized with different levels of FeEDDHA (trunk injected and through soil) and FeSO 4 · 7H 2 O(trunk injected). Leaves were collected 100 days after iron application and analyzed for micronutrients. The injection with 100 g FeSO 4 · 7H 2 O/tree increased the Fe contents in the leaves of both cultivars, and with 100 g FeEDDHA/tree in the leaves of Ruzaiz cultivar. Soil application of FeEDDHA was not effective. The contents of Cu, Mn and Zn in the leaves were not affected by Fe fertilization.
