Temporal Variation in Physico-Chemical and Phytoplankton Analysis of Madhav Sagar Pond, Sikar (Rajasthan)

The research paper reports on study carried out from January 2018 to December 2019 in Madhav Sagar pond. The study emphasizes the local and regional climatic influence on phytoplankton species composition, diversity and density variation in the pond ecosystem. In this study Nitrate, Inorganic phosphorous, Temperature, pH, Conductivity, Dissolve oxygen, Chloride, Total hardness, Calcium and Sodium parameters were analyzed. The result obtained indicates that a significant difference in abundance of phytoplankton groups was found between year 2018 and 2019. Though the highest phytoplankton abundance was observed in July 2018 and February showed the highest number of taxa (highest diversity). Chlorophytes were the major dominant group in both periods.
