DIVERSITY OF MICROALGAE IN THE PADDY FIELDS OF KIZHAKKAMBALAM, KERALA, INDIAMini C.V. and A.K. BopaiahAbstract The distribution of microalgae in relation to the seasonal variation of paddy fields at Kizhakkambalam, Kerala has been undertaken for the first time from this area. A regular seasonal collection has been made during several field trips from June 2017 to may 2018. The microalgal flora comprised of 21 taxa belonging to Cholorophyceae, Bacillariophyceae, Cyanophyceae and Euglenineae were identified. Physico âchemical parameters were also analyzed in the laboratory. Moderate temperature, high light, nutrient and water availability appears to be better for micro algal growth in the rice field habitat. The seasonal estimation of microalgae shows that during pre-monsoon the members of Bacillarophyceae were more in number, during monsoon and post-monsoon the members of Chlorophyceae were more abundant. Members of Cyanophyceae and Eugleninae were observed during winter season.
