Diversity of AM Fungi in Different Farm Soils

The present investigation was focused on assessment of AM fungal diversity in different agricultural soils. Soil samples were collected from three different agricultural soils. All the three soil samples were analysed for physico-chemical characteristics (standard method) and diversity of AM fungi. By considering spore wall layers, shape and colour of the spore, 8 different species was observed morphologically in eastern block soil (sandy clay loam) namely, Glomus clarum, Glomus fasciculatum, Gigaspora decipens, Glomus etunicatum, Glomus mosseae, Glomus viscosum, Scutellospora sp. and Glomus geosporum. Six different AM species were identified from millet breeding station sample (clay loam) as, Glomus mosseae, Gigaspora margarita, Glomus fasciculatum Scutellospora sp. and Glomus geosporum. From dryland sample (sandy clay loam), six species identified are Acaulospora sp., Glomus mosseae, Scutellospora sp., Gigaspora gigantean and Glomus albidum.
