The present study was conducted at the Department of microbiology, GKVK, University of Agricultural Sciences, Bengaluru-65. Spent mushroom substrate obtained after the mushroom cultivation was rich in nutrients and it was used as carrier material for the survival studies of plant growth promoting microorganisms (Pseudomonas fluorescens, Bacillus megaterium and Trichoderma harzianum) at different time intervals by serial dilution plate count technique up to 120 days. At all the intervals of population studied, treatments which received inoculation of single organism showed higher population compared to the population in consortia which contained all the three plant growth promoting microorganisms (Pseudomonas fluorescens + Bacillus megaterium + Trichoderma harzianum). The survivability of plant growth promoting microorganisms on both oyster mushroom and milky spent substrates were on par each other. From the results of survivability studies it is confirmed that, spent mushroom substrate can be used as carrier material for plant growth promoting microorganisms. Among the different plant growth promoting microorganisms, Trichoderma harzianum showed better survivability.
