Introduction Free living nitrogen fixing bacteria have been considered as an alternative for inorganic nitrogen fertiliser for promoting plant growth (Ladha and Reddy, 2000; Park et al., 2004). Inspite of the fact that a variety of nitrogen fixing bacteria have been isolated from the rhizosphere of various crops, interest in isolating more beneficial plant growth promoting bacteria has increased recently due to their potential use as bio fertiliser (Vessey, 2003). Cultivated rice (Oryzasativa...
