In order to study the effects of mycorrhizal fungi inoculated of three different soil types, an experiment was conducted based in a complete randomized design with four replications in a factorial arrangement at greenhouse of the Gonbad Kavous University in 2013. Treatments were included soil inoculation (with Glomus mossea, G. intraradices and non-inoculated soil), and different soil types (normal soil, saline soil and forest soil). Measured parameters were wet and dry weight of shoot, wet and dry weight of root, root volume, phospherous concentration of shoot and microbial respiration of soil. Results of variance analysis showed that all traits measured at different levels of mycorrhiza except for soil microbial respiration had significant difference (P≤0.05). All traits measured in different soil levels except the root volume were significantly different (P≤0.01). The comparison of simple effects at different levels of soil microbial respiration characteristics of forest soil and other characteristics in normal soil showed highest average, but all characteristics in saline soil had the lowest average. At different levels of mycorrhiza, mycorrhizal strains G. mossea and G. intraradices had positive and significant effect relative to control on all traits except for microbial respiration, respectively. So, mycorrhizal fungi had positive effect on nutrient absorption and increased root and shoot growth of clover in different soils.
