The Effects of Arbuscular Mycorrhizal Fungi on Nitrogen Concentration of Berseem Clover in Contaminated Soil with Cadmium


Soil Science Department, Zanjan University, Zanjan, Iran


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 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 reduced nitrogen concentration in root and aerial plant 28.3% and 35% respectively.
