Applications of Plant Growth Promoting Bacteria (PGPB) and Vesicular Arbuscular Mycorrhizal (VAM) Fungi on Aloe barbadensis Mill., a Medicinally Important Succulent Herb

Background: Application of biofertilizers is an appropriate replacement of harmful chemical fertilizers to fulfil the rising demands of herbal medicine. The main objective of this study was to establish a potent biofertilizer with the help of microbial consortia and observe their effects on the primary growth of Aloe barbadensis Mill. Methods: Rhizospheric soil of the plant Aloe barbadensis Mill. was taken and isolation, characterization and identification of the vesicular arbuscular mycorrhiza (VAM) fungi, rhizospheric bacteria and the VAM fungal spore associated bacteria was done. To check the microbial effects on morphological parameters of the plant, a total number of eight experimental sets were prepared by using different microbial strains. Result: In our experiment, VAM+ABM1 treated plant set showed the significant responses in plant primary growth which can be used as a potent biofertilizer in more sustainable way.
