Abstract: Sustainableagriculture involves the use of biofertilizers and biopesticides to reduce the application of chemical fertilizers. Microbial consortium-based sustainable and economicbionutrient package for Aloe vera has been developed to reduce reliance on chemical fertilizers. Consortium includes Acinetobacter radioresistens SMA4, Bacillusthuringiensis SMA5, Brevibacteriumfrigoritolerans SMA23 and Pseudomonas fulva SMA24. In the earlier studies all these four bacterial strains have been found to possess multiple plant growth promoting attributes. Consortium used in this study increased all biometric parameters in Aloe verasuch as plant biomass, root weight, shoot weight and gel content. Increase in aloinA content was also observed in this study in plants treated with PGPR.
Keywords: Aloe vera, Consortium, PGPR, Aloin, Biofertilizer
