A study was made to investigate the impact of pond sedimentary soil for renovation of degraded land and biomass production of soybean and mycorrhizal status. Pond soil when amended with renovated land soil decreased the plant height and shoot length than crop land soil. Length of root (26.66cm) was increased in renovated + pond soil than cropland soil. Cropland soil showed significant growth rate of nodule, leaves and auxillary branch. Number of pods (154) in cropland soil showed promising results than that of renovated soil+ pond soil. Fresh weight of shoot, fresh wt of root, dry weight of shoot, dry weight of root and area of total leaves were increased in cropland soil. Total yield per hector was increased in cropland soil than renovated + pond soil. Percent root AMF colonization and Arbuscular mycorrhizal fungi (AMF) spore density was found promising in both soils. In both soils Acaulospora, Gigaspora, Glomus,Entrophospora and Scutellospora was found frequently but Acaulospora and Glomus genera was found dominant. Vesicular, arbuscular and hyphal colonization was found in both soil of soybean plant root.
