Abstract

Purpose: Purpose of the present study is to check the potency of the strains Bacillus thuringiensis A5-BRSC and Bacillus megaterium ATCC 9885 for promoting growth of different plants without hazardous chemical fertilizers.

Methods: Four non-leguminous seasonal plants like Amaranthus; Ocimum, Abelmoschus and Capsicum are used to study combined growth promoting effects of two bacteria viz. Bacillus thuringiensis A5-BRSC and Bacillus megaterium ATCC 9885 under pot condition. Different morphological parameters like shoot height, leaf area, fresh weight and dry weights of the plants; as well as biochemical parameters like leaf chlorophyll content, catalase and peroxidae enzyme activities of both culture treated and untreated plants were investigated.
Results: All the biofertilizer treated plants showed remarkably higher results in all parameters, except chlorophyll content, than control plants.
Conclusion: The strains proved as potential strains for plant growth promotion in pot study and hence may be used as biofertizer under field condition for sustainable agriculture.
Key words: Bacillus thuringiensis, Bacillus megaterium, dual inoculation, pot culture
