Diatoms are a large and diverse group of eukaryotic algae belongs to the members of Bacillariophyceae. Usually microscopic, diatoms are well known to be abundant in paddy fields. They are the largest group of biomass producers on earth; they are one of the predominant contributors to global carbon fixation and 25% of the total oxygen production on earth. Diatoms are enormously successful organisms as judged by their adaptability, distribution, biomass and relative antiquity. In the present study focused on the prevalence of diatoms from different paddy fields of Rasipuram area, Namakkal District, Tamilnadu, India. Total number of 200 samples were collected from paddy fields of Rasipuram area. 351 isolates of 18 diatom genera was recorded during this study period. Among the four different seasons, it was found that July to August, 2011 recorded the highest number of (190) and the lowest number (87) was recorded during December, 2012 to February, 2013. Among them dominant genera were Navicula sp. (49 isolates) followed by Nitzchia sp. (48 isolates) during July to August, 2011.
