Monika Patralekh and Prasant Patar

ABSTRACT:

Primary productivity is an important parameter to assess the quality of water. High productivity nature of water indicates greater degree of pollution. Phytoplanktonproductivity of Shivaganga pond of Baidyanathdham, Deoghar, Jharkhand was estimated at monthly intervals in the year 2002-2003. Noticeable data were collected. Minimum G. P. P. (0.0525mgc/l/hr) was observed in winter (December) and maximum (0.5625 mgc/l/hr) in summer (May), N.P.P. was assessed highest (0.4425mgc/l/hr) in March (summer) and lowest (0.015mgc/l/hr) in December (winter) Ratio of N.P.P. and G.P.P. was found lowest in July and highest in March. Community respiration was minimum in November and maximum in June. Ratio of G.P.P and respiration ® was analyzed minimum (1.285) in July and maximum (30.5) in March, which reflects the degree of pollution.
