Mycorrhiza is one of the most important groups of microorganisms which can effectively support the vegetation development in distress habitat like sponge iron solid waste dump. Arbuscular Mycorrhiza (AM) root colonization in the herbaceous vegetation of different age series sponge iron solid waste dumps were assessed. Among the grasses all the species were associated with AM in all the waste dumps and such observation highlights the effective role of grasses as pioneer species during vegetation succession. The percentage of mycorrhizal colonization in the herbaceous plant species decreased with increasing age of the waste dumps and as age of the waste dumps increased, the percentage of plants with very high level decreased in all the dumps. Highest percentage of mycorrhizal root colonization was observed in Eragrostis tenella which was dominant species of the waste dumps. More numbers of plants were with hyphae & arbuscules (H+A) structure than hyphae & vesicle (H+V) in the waste dumps reflects the importance of synergistic action of hyphae and arbuscule for transfer of nutrients from low nutrient content substrate rather than the development of storage structure like vesicle. Form the study it was concluded that establishment of mycorrhizal association is quite essential for proper vegetational development and subsequent reclamation of the sponge solid waste dumps.
