The present investigations carried out on some paddy fields of Guntur district of Andhra Pradesh (India) to study the biodiversity of Cyanobacteria from July 2010-June2011. Cyanobecteria are the most important nitrogen-fixing organisms because of their autotrophic nutrition and flourish in rice fields and known to sustain the fertility of this ecosystem. The rice ecosystem allows Cyanobecteria to function properly, selectively and effectively. Thirty-six species of cyanobecteria recorded. The present investigation carried out the diversity of nitrogen fixing Cyanobacterial communities of Guntur rice fields, Andhra Pradesh, India at Tenali mandal site water and soil samples taken, samples were analysed for taxonomic enumeration. Thirty-six species recorded. Most of them were from the orders of Nostocales, Chroococcales and Stigonematales.
