DIVERSITY OF BLUE-GREEN ALGAE AND STUDY ON RELATED PHYSICO-CHEMICAL PARAMETERS OF PADDY FIELDS OF CHHATARPUR DISTRICT OF MADHYA PRADESH

Neha Jain

Occurrence of Blue-green algae in local paddy fields of Chhatarpur district M.P. has been under taken for the first time in this area. A regular monthly collection has been made during cropping season May to October in year 2013. In the present investigation, rich diversity of Blue-green algae was recorded. Total 66 Bluegreen algal species with wide range of thallus structure were found, belonging to various orders i.e., Chroococcales, Oscillatoriales, Nostocales, and Stigonematales etc. Total nine physico-chemical parameters (pH, EC, Temperature, soil N, P, K and Calcium content) were chosen for study. Chlorophyll-a content were also estimated during study period as an index of growth. This study reveals that comparatively lesser number of Blue-green algae were growing in summers in comparison to rainy season. The unicellular forms were abundant during summer while number of filamentous (heterocystous and non-heterocystous forms) increased during rainy season.
