Abstract
A study was conducted for the cyanobacteria in Rice Fields of saran district of Bihar, India. In the district, on the onset of monsoon the said rice field remains under water logged condition, which favors the rice crop. Water logged condition on the other hand, favours the growth of Cyanobacteria. Total 16 different Cyanobacteria were recorded from rice field the significantly most common species are filamentous cyanobacterial strains identified from soil samples and water sample 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 fertschii, Rivularia aquatic, Gloeotrichia indica, G. natans.
