Fungi within the phylum Gigasporomycota were investigated in iron mines fields in Chhattisgarh. Chhattisgarh is located between 21.27°N 81.60°E. The fungi within this phylum form arbuscular mycorrhizal symbiosis with plant ischolar_mains. Sampling of soil was carried out to a depth of 30 cm in the rhizosphere. Arbuscular mycorrhizal fungi were found at all 10 sampling sites in each field, at densities in between 0 to 03 spores per g dry weight of soil. Significant differences in spore densities were found between unmined, mined and dumped area of iron mines fields. Our study revealed that the upper half (0-15 cm) of the soil profiles had significantly more spores than the lower half (15-30 cm). Spores from ten sampling sites were identified from the indigenous soils. Almost 90% were shown to belong to the genus Gigaspora. The other genera found were Glomus and Sclerocystis.Keywords

Vesicular- arbuscular mycorrhizal associations with plants are widely distributed and are geographically ubiquitous. Vesicular- arbuscular mycorrhiza (VAM) fungi a group of important soil micro-organism. VAM importance in iron ore mines for revegetation and reclamination. In these present work inoculation studies with VAM of existing five tree species are namely, Dulbergia sisso, Gmelina arborea, , Diospyros melanoxylon, Delonix regia, Dendrocalamus strictus, in nursery pot culture. Comparative studies in different parameter like percentage ischolar_main infection, no. of VAM, ischolar_main length, shoot length, fresh and dry biomass, ischolar_main and shoot length ratio, fresh and dry biomass ratio within 90 days inoculation. In many parameters the VAM inoculated plants show better performance and encouraged results compare then non inoculated control plants.
