Number of mycorrhizal endogone spores ranged between 13.4 and 220 per 100 g air dried soil in ten representative Bangladesh soils. The presence of greater number of spores was always associated with the incidence of abundant mycelia. The formation of spores and mycelia was restricted by low soil pH. Soil sterilization by heating at 105 degree C for 24 hrs completely inhibited the infection of rice roots by indigenous mycorrhizal fungi. Mycorrhizal infection greatly improved the growth and nutrient (nitrogen, phosphorus and zinc) contents of rice plants.
