Abstract

The analysis of physico-chemical parameters were carried out during June 2015 to May 2016 from Kallayi River, Kerala, India. The maximum water and air temperature were observed in summer season (May). The water is more transparent during summer season (May). The maximum pH value is observed in summer season (May). The water showing more dissolved oxygen during the rainy season (November). The maximum carbon dioxide content of the river was reported in the rainy season (June). The alkalinity is observed maximum during summer season (April). The maximum electrical conductivity in water was observed in the winter season (December). The maximum total dissolved solids were reported in summer season (May). The total suspended solids reported maximum during summer season (May). Dissolved nutrients like nitrate, phosphate and silicate were reported accordingly. Nitrate maximum during in rainy season (September), phosphate maximum in summer season (May) and the silicate maximum in the rainy season (June). The maximum gross primary productivity reported during summer season (May).The maximum net primary productivity and gross primary productivity was observed in the rainy season (May) and the maximum community respiration was reported during summer season (April).
