Abstract

Piriformospora indica biomass generated in different growth media Rose Bengal medium, Kaefer's Medium, Enriched Soil Medium, Malt extract Medium and Czapek Dox was quantified and  their bioinoculum potential was compared using  moong bean (Vigna radiata) as  test plant. Plant chlorophyll content in response to inoculations was lowest in Rose Bengal medium (2.772mg plant^-1) and highest due to inoculum produced on Enriched soil Medium (3.694 mg plant^-1). The highest nitrogen content (19.260 mg plant^-1) was recorded by inoculum produced on Kaefer's Medium followed by Enriched Soil Medium (19.123 mg plant^-1), ME (18.19 mg plant^-1) and CD medium (17.71 mg plant^-1). The highest plant phosphorus uptake was registered in Enriched Soil Medium (17.153 mg plant^-1) followed by Kaefer's Medium (17.023 mg plant^-1). Maximum dry weight of plants was observed by inoculation with fungus cultured in Kaefer's Medium (3.416 g pot^-1) and Enriched Soil Medium (3.349 g pot^-1). Thus, growth medium used for the culture of fungus can influence its bioefficacy as plant growth promoting agent and Piriformospora indica can be grown on cost effective and simple mass multiplication medium which could augment its usage for commercial purposes.
