The ability of an ecosystem to build up, at the expense of external energy both radiant and chemical; primary organic compounds with strong chemical potentials for further transformation and flow to higher system levels is referred to as primary production. The goal of this study is to give baseline data on Hattikuni Reservoir's primary productivity in Yadgiri District, Karnataka, India, in order to improve reservoir management. The experiment was conducted for a year (February 2015 to January 2016) in the first week of each month, utilising the 'light and dark bottle' method. GPP was found to be maximum in pre-monsoon season 0.95 gC/m3/hr and minimal in monsoon season 0.55 gC/m3/hr, NPP was found to be maximum in post-monsoon season 0.48 gC/m3/hr and minimum in monsoon 0.27 gC/m3/hr, while CR was found to be maximum in pre-monsoon season 0.59 gC/m3/hr The findings show that a higher Hattikuni reservoir productivity promotes the growth of zooplanktons and higher organisms in the reservoir.
