The effects of Arbuscular Mycorrhizal fungi on nitrogen concentration of berseem clover were examined in contaminated soil with cadmium. Examined factors included: levels of arbuscular mycorrhizal fungi inoculation (Glomus mosseae) (With and without inoculation), and different levels of soil contamination by cadmium (0, 5, 10, 20, 40 and 80 mg.kg-1). The results showed that the effects of cadmium levels and mycorrhiza fungi were significant on nitrogen concentration (P≤ 0.01). Arbuscular mycorrhizal fungi increased nitrogen concentration in the root and aerial plant 30% and 40.3% respectively. Also cadmium in concentration of 80 mg.kg-1 reduced nitrogen concentration in root and aerial plant 28.3% and 35% respectively.
