The aim of the present study is to analysis the availability of nitrogen, phosphorus and potassium (NPK) content in the soil and to check the association of Glomus macrocarpum with Allium cepa roots in two different soil samples with and without NPK concentration. The result confirmed that the ECR road soil samples showed more number of AMF spores when compared to other region. Glomus macrocarpum was isolated and used for trap culture for multiplication of Spores. Pot A and Pot B showed significant growth when compared to other two pots without NPK. The statistical analysis of mycorhizal colonization was also revealed that mycorrhizal association was higher in pot with red soil.
