Arbuscular mycorrhizal fungi are the most important members of soil microbial community in ecosystem. These useful organisms form an indespensible component of any fertile soil. It is said that a good quality of 1 kg soil is almost equal to 1 kg of gold. Symbiotic relationships of AMF provide an alternative for survival of plants in highly stressed areas, this association helps in uptake of P as well as other minerals, maintain better water balance, increase plant biomass and produce growth promoting substances. Strategies to promote plantation in poor or degraded soil includes introduction of native AMF in soil. During present study a survey was undertaken in degraded forest areas with certain grasses in Godhra and Baria divisions, 115 kms from Vadodara city in India. Rhizospheric soil samples were collected from 22 different places. Soil samples of Heteropogon contortus showed more number of AM spores (220/100 g) as compared to that of Themeda triandra 165/100 g. Kalitalai soil samples Chloris barbata showed more number of spores (150/100 g) than that of Rampara (110/100 g). The percentage occurence of AM spores was more in Bandheli. Analysis of AM spores resulted in identification of different species belonging to three genera i.e. Glomus, Gigaspora, and Acaulospora.
