摘要:Phytoplankton Primary production in the river Jharahi at Mairwa was studied in 2008 and 2009. Gross Primary Productivity (GPP) of the river water at the different sites ranged from 0.044 mgC/l/hr to 0.422 mgC and 0.037 mgC/l/hr to 0.394 mgC/l/hr in the second year. Net Primary Productivity 0.314 mgC/l/hr in the first year and 0.021 mgC/l/hr to 0.297 mgC value of the river ranged from 0.469 to 0.799 in the first year and 0.427 to 0.754 in the second year Respiration (CR) ranged from 0.023 mgC/l/hr to 0.108 mgC/l/hr in the first year and 0. the second year of observation. CR as percent of GPP ranged from 20.109 to 53.125 in the first year and from 24.619 to 57.292 in the second year.
