The present research work deals with the assessment of pollution level in the Yamuna River water.
Through this study an attempt has been made to analyze the physico-chemical parameters of
untreated and bacterial consortium treated Yamuna river water and its effect on seedling growth of
Cajanus cajan. The bacterial consortium treated water increased the germination percentage, shoot
length, root length, shoot biomass and root biomass while in untreated water a significant decrease
of growth was noticed. Among the different concentrations (25 %, 50 %, 75 % & 100 %) of Yamuna
river water, 25 % concentration of untreated water & 100 % concentration of bacterial consortium
treated water sample showed stimulatory effect on the seed germination & other growth parameters
of Cajanus cajan over control. The result of the study indicates that Effective bacterial consortium
helps in the reduction of water impurities and can be effectively used for irrigation.
