The objective of this research was to evaluate the effect of organic matter on the association with Glomus intrarradices and soil contamination on beans (Phaseolus vulgaris L.). The study was done under greenhouse conditions at the Montecillo Campus of the Postgraduate College, Mexico. Two soils were used, one irrigated with sewage water and the other one with clean water from a well. Half of the plants were inoculated with Glomus intrarradices. Vermicompost was used as a source of organic matter. There were highly significant increases (p=0.05) in all the variables recorded due to the application of organic matter, and to the inoculation with Glomus intarradices. The irrigation source of the soils used for this experiment only had a significant effect (p=0.05) on pod number and nitrogen fixation. The best growth and grain yield occurred with inoculated plants and supplementary organic matter.
