Abstract

Rhizosphere, rhizoplane, phyllosphere, phylloplane and endophytic mycoflora of Cajanus cajan, Linn. was isolated. The potential of the isolates for plant growth promotion was evaluated by screening them for Indole -3 acetic acid (IAA) production. 112 species belonging to 32 genera were screened during the present study. 23.62 % of the isolates could produce IAA, in medium containing L- tryptophan. Screening of IAA production was carried out colorimetrically as well as on nitrocellulose membrane.
