Abstract

Life on earth is not possible without water, it is most precious substance on earth and ponds are traditional sources of water. The present study investigates the primary productivity of pond water ecosystem. The Light and Dark bottle method is used to measure the primary production and it depends on the planktonic biodiversity. In the present study monthly variations of physico-chemical parameters were statically analyzed and graphically presented. The pond was selected for a period of three months March to May 2024. The different physico-chemical parameters like air temperature (23°C to 30°C), water temperature (11ºC to 18ºC), EC (60 µS/cm to 76 µS/cm), T.D.S (31 ppm to 38 ppm), alkalinity (21mg/l to 25 mg/l), hardness (31 mg/l to 34 mg/l), calcium hardness (4 mg/l to 4.8 mg/l), magnesium hardness (4.32 mg/l to 5.76 mg/l), Chloride content (2 ppm to 5 ppm), pH (7.2 to 8) dissolved oxygen (6.80 mg/l to 13.90 mg/l) as well as Gross primary productivity (GPP) (0.22 mg C/l/h to 0.33 mg C/l/h), Net primary productivity (NPP) (0.15 mg C/l/h to 0.37 mg C/l/h) and Community respiration (CR) (0.18 mg C/l/h to 0.56 mg C/l/h) were also analyzed. The study concluded that the water of Sourabh van vihar pond showed variations in physico-chemical parameters and primary productivity as well as productivity status in these three months

Conclusion

Physico-chemical parameters and productivity of Sourabh van vihar, pond, Palampur Himachal Pradesh was studied from March 2024 to May 2024. The primary goal of this study was to investigate the interrelationships between the physico-chemical parameters and productivity. The primary productivity of pond can be affected by physico-chemical parameters of pond water. The nature of the water body is oligotrophic. The oligotrophic pond are small aquatic community. The water is clear and the bottom is sandy and physical characteristics of oligotrophic pond include blue or green highly transparent water having low dissolved nutrients and low primary productivity
