The last few decades have seen a flurry of activity in the synthesis and development of Plant growth promoting bacteria and fungi and their production as plant growth promoters. Various strategies can be envisaged to synthesize by exploiting the reactivity of this organisms with their derivatives by various researchers. Biocontrol agents and its derivatives were also reported to have promising bioactivities, including antibiotic production, antibacterial, siderophore and hormones producing properties, primary, secondary and volatile metabolites producing activities. The aim of this book is to provide a brief knowledge about plant growth promoting rhizobacteria and their derivatives in promotion of biometric parameters of Glycin max L. We have included their characterization of different parameters in plant growth promotion and by various biometric parameters in soybean in pot and field trials.
