Arbuscular mycorrhizal status of Pippali a medicinal plant species in the Jorhat district of Assam, India were surveyed during 2018. Percent colonization, spore density and diversity of arbuscular mycorrhizal fungi associated with the rhizospheric soil and roots of pippali growing wild as well as under cultivated conditions were investigated. It was found that 100% of the surveyed sample was of mycorrhizal infestation. The spore colonization per cent of AMF ranged from 30.80 to 66.50% spores per 100 g of soil. The maximum spore population (185.80 spores/ 100 gm of soil) was obtained on soil samples collected from Gibbon wild life sanctuary. This was followed by soil sample collected from Katoni par Soil sample collected from Upper deori gaon, Nakachari gaon, and Nagajanka showed spore population of 168.80 to 154.65 spores/100 ml of soil. Result showed that root colonization by abuscular mycorrhizal fungi both in roots and soil of Pippali. But, percentage of root and soil colonization varies according to location. Variation in the spore density and percent colonization among different sampling sites could be attributed to host specificity, adaphic and climatic conditions. After comparing with synoptic key the genus of the mychorrhiza was identified tentatively as Glomus spp.
