The microbially enriched vermicompost was used as potting mixture for raising seedlings of aonla and bael. Seedlings showed significant increase in shoot and root length over the seedlings grown in unamended vermicompost. Aonla and bael seedlings raised in microbial enriched vermicompost were healthier and showed significantly more plant dry weight than seedling raised in vermicompost without addition of microorganisms. Azotobacter chroococcum, PSB and P. maltophilia population were higher in the rhizosphere of the seedling raised in microbially enriched vermicompost at the time of uprooting the plants. The inoculated strains persisted in the rhizosphere and their count increased at the time of harvest. Microbially enriched compost was proved better potting mixture than unamended vermicompost for raising aonla and bael seedlings. Aonla and bael seedlings raised in microbially enriched vermicompost T5 (Azotobacter + PSB + PM4 + AM fungi) recorded 14.8% and 18.7% increase in root length and 22.5% and 39.6% increase in shoot length over control (without enrichment), respectively. Seedlings grown in AM fungi enriched vermicompost had higher infection of AM fungi. The seedlings raised in vermicompost where no AM fungi were added showed very low % infection (1.0-2.1%). Vermicompost enriched with Azotobacter + phosphate solubilizing bacteria + AM fungi (T3) showed 40% and 36% VAM infection in aonla and bael, respectively.
