The effects of Arbuscular Mycorrhizal fungi on nitrogen concentration of berseem clover wereexamined in contaminated soil with cadmium. Examined factors included: levels of arbuscular mycorrhizalfungi inoculation (Glomus mosseae) (With and without inoculation), and different levels of soil contaminationby cadmium (0, 5, 10, 20, 40 and 80 The results showed that the effects of cadmium levels andmycorrhiza fungi were significant on nitrogen concentration (P≤ 0.01). Arbuscular mycorrhizal fungiincreased nitrogen concentration in the root and aerial plant 30% and 40.3% respectively. Also cadmium inconcentration of 80 reduced nitrogen concentration in root and aerial plant 28.3% and 35%respectively.
