Abstract
The study investigated the effects of interactions between the Rhizobium and Mycorrhizal fungi on nitrogen and phosphors accumulation, increased N and P content, biomass production and percentage of colonization by Trifolium subterraneam and TrifOlium alexanderinum. The plants were grown in a greenhouse until the flowering stage. The obtained results demonstrated that the inoculation of clovers increased the plants biomass, content of P and N and colonization of mycorrhizal in comparison with single and uninoculation with microorganisms under the study. But T. subterraneam with finely branched and hairy roots had lower response to mycorrhizal associations. The result indicated that the synergistic or additive interactions among the components of Rhizobium, Mycorrhizal and plants association increased plant productivity.
