Abstract

The primary productivity of the river River Kharashrota (Orissa) has been analysed both spatially and seasonally. The maximum GPP was noted during summer season and minimum in rainy season at all the six stations. The annual average GPP varied from 0.075±0.009 gC.m-3.h-1 to 0.938±0.103 gC.m-3.h-1.The NPP value varied from 0.012±0.001 gC.m-3.h-1 to 0.832±0.081 gC.m-3.h-1 and exhibited an increasing trend from the month of September to February. The community respiration (CR) ranged from 0.026±0.002 gC.m-3.h-1 to 0.496±0.043 gC.m-3.h-1 and exhibited a systematic seasonal pattern with maximum and minimum value during summer and winter respectively at all the stations. The correlation of NPP, GPP and CR with some of the physico-chemical parameters has also been established.
