Abstract: Chitosan is a polysaccharide biopolymer derived from Deacetylation of chitin using microbes. Chitosan not only stimulates growth and increases the crop yields but also alleviates the harmful effect of abiotic stress on plant growth as well as preserves enzymatic activity of the seeds. The objective of this study was to investigate the effects of chitosan coated seeds on germination, seed vigor index, root and shoot length of rice seeds using mangrove soil. The chitosan was dissolved in 0.5% and 1% acetic acid and subjected to seed priming. the seeds coated with chitosan obtained from IS 5 were found to be efficient in enhancing the seed vigor and germination of the coated seeds. The IS 5 was subjected to double pass FASTA for genus level identification and belongs to Bacillus Spp. Hence, from this investigation was proved that chitosan coating enhances the seed germination, preserves the enzyme activity and protects the seed from salt stress.
