Biopriming of seeds with Plant Growth Promoting Bacteria (PGPB) is considered to be ecologically sound and beneficial to both seed and environment. Therefore to ensure the benefits, a biopriming study was conducted in paddy seeds with different liquid microbial cultures. The results showed that the seeds soaked in equal volume of liquid microbial cultures viz., Azospirillum or phosphobacteria @ 1:50 dilution for 18 h or Pink Pigmented Facultative Methylotroph (PPFM) @ 1:100 dilution for 24 h have recorded the higher germination and vigour. Pink pigmented facultative methylotroph has performed well among these microbial cultures in enhancing the seed germination. Also, the viability and vigour of bioprimed seeds were not much affected in three months storage. In addition, the microbial population of 12 x 105 to 8 x 104 CFU g-1 of seed was observed in the bioprimed seeds. Nevertheless, the population has been reduced between 9 x 105 and 2 x 104 CFU g-1 of seed in three months storage.
