A study was conducted on the Biodiversity of Cyanobacteria in the Rice Fields of the Saran district in Bihar, India. Cyanobacteria is the unique component of the microbial population of the rice fields which significantly enhances the nitrogen status of the field by fixing atmospheric nitrogen. In the district, at the onset of monsoon, the said rice field remains under water logged conditions, which favors the rice crop. Water logged conditions, on the other hand, favours the growth of Cyanobacteria. A total of 16 different Cyanobacteria were recorded from rice fields the significantly most common species are filamentous cyanobacterial strains identified from soil samples and water samples have been found to occur throughout every year of monsoon. The recorded cyanobacteria species were Osillatoria Formosa, O. obscure, Anabaena doliolum, A. fertillisima, A. variabilis, Aulosira fertilissima, Cylindrospermum majus, C. musicola, Nostoc commune, N. linckia, N. muscorum, Plectonema notatum, Scytonema fertsmuscorum, Plectonema notatum, Scytonema fertschii, Rivularia aquatic, Gloeotrichia indica, and G. natans.
