Abstract

In recent times, there has been a renewed interest in the search of plant growth promoting rhizobacteria (PGPR) for sustainable crop production. Rice is an economically important food crop, which is subjected to infection by a host of fungal, viral and bacterial pathogens. In this study, an attempt was made to isolatePseudomonas spp., a potent PGPR in the rhizosphere. Through appropriate microbiological and biochemical methods, the study demonstrated the presence of fluorescent and non-fluorescent Pseudomonads in the rhizosphere of chemical intensive rice growing environments. Augmentation of such PGPR including,Pseudomonads in the rice ecosystems will ensure a healthy micro climate for rice.

Key words: Pseudomonas, rice, plant growth promoting rhizobacteria (PGPR).

Abbreviation

PGPR, Plant growth promoting rhizobacteria; KMB, King’s medium B metals.
