| Abstract: | Two
biofertilizer agents, Azospirillum amazonense A10 and Bacillus
megaterium P7, alone and in combination
increased
the grain yield of rice in autoclaved soil by 103-256% over control. Colonies
of A, amazonense and B.
megaterium
were distinguished from the contaminant phosphate solubilizing bacteria
(PSB) and Azospirilla colonies
in
the respective media based on colony morphology, colour and thickness of
clearing zone, Population densities of A,
amazonense
and B. megaterium were found to be 2.6 x 108 and 2.9 x 108 CFUg .]
soil, respectively at 48 day post
transplanting.
Protein and antibiotic resistance profiles of the inoculated and reisolated A.
amazonense, B.
megaterium
and the contaminant colonies with the pure cultures indicated that the
isolates were able to establish in
the rice rhizosphere with the resultant enhancement of
plant growth and yield. |
