Co- inoculation with symbiotic microorganisms to create a successful system of biological nitrogen
fixation in a crop can lead to many profits for plants. The present work was to evaluate the single
and co-inoculation effects of Azospirillum lipoferum (Az 204) and Phosphate Solubilizing
Microorganism, Bacillus megaterium (PB1) on rice variety of ‘Co 47’. The biofertilizers are applied
to rice seeds and pot experiments were performed to analyze the symbiotic relationship of these
biofertilizers in individual and combined form. Plant Phytotoxicity and vigor index were calculated
from root and shoot length and compared with one another. The results indicated that the coinoculation
of rice seeds with A. lipoferum and B.megaterium had significant effects on root and
shoot length of plant in compared to either single inoculation or control plants. Hence it can be
suggested that the co –inoculation of A. lipoferum and B. megateium can improves some growth
indices in terms of root and shoot length.
