| In order to investigate the effect of Arbuscular-Mycorrhizal fungi on growth in Berseem clover (Trifolium alexandrum L.) plant under different levels of sewage sludge, a greenhouse experiment was conducted in a randomized complete block design with twelve treatments and three replications. The treatments of the experiment were a combination of three Mycorrhizal fungi status (Mi= Glomus intraradices, Mm= Glomus mosseae and M0= non-inoculation) and four sewage sludge levels (S0=0, S1=25, S2=50 and S3=100 ton per ha). The results showed that adding sewage sludge significantly increased dry weight growth parameters of clover, root dry weight, root length and weight of nodes in clover plant, but the percentage of roots colonization was significantly reduced. Root inoculation of clover plant with two species of Arbuscular-Mycorrhizal Fungi had positive and significant effect on most growth parameters of clover in comparison to non-inoculation. |
