Abstract
The present study is carried out for estimation of primary productivity in relation to water quality of Chikklingadalli water body of Chinchollitaluk, Kalaburagi district, every month water samples were collected from the four different sampling sites of the water body from Feb 2016 to January 2018. Various water quality parameters including Atmospheric and water temperature, DO, Free CO2, Total alkalinity, Total hardness, Chloride, Nitrate, TDS etc. were estimated, whereas correlation and coefficient between parameters were analyzed. During the study period all the values of the physico-chemical parameters are within the permissible limit. Primary productivity values were recorded highest during summer season and northeast monsoon season and lowest values recorded during the southwest monsoon season from study area. Data subjected to statistical analysis.
Keywords: Chikklingadalli water body, water quality, gross primary productivity, net primary productivity and community respiration.
