Evaluation of Ganges water quality and its suitability for Agriculture use from Rishikesh to Prayagraj, India

Authors attempted to study the quality of Ganges water from Rishikesh to Prayagraj during July 2019 to December 2019 based on quality parameter tools. The Ganges water was examined for various physico-chemical parameters such as pH, TDS, DO, EC and elements such as Sodium (Na), Potassium (K), Calcium (Ca), Magnesium (Mg). Sodium Adsorption Ratio (SAR), Kelly's ratio (KR) and Soluble Sodium Percent (SSP) were evaluated to find out the suitability of Ganges water for agriculture purposes. SAR was found to be ranged from 0.24 to 4.01 with a mean value of 0.87(meq/L). The result indicates that Ganges water is suitable for agriculture purposes in the area studied.
