Today quality of river water is an issue of serious concern, nowadays wastewaters from almost all the industries and domestic effluent are discharged untreated in to the rivers and ultimately agriculture fields are being generally irrigated from these polluted water resources loaded with harmful toxic substances which drastically affect the yield. Keeping this in mind, the aim of this  study was to analyse Hindon River water for physico-chemical properties (pH, Electrical conductivity (EC), Total alkalinity, Total dissolved solids (TDS), Total suspended solids (TSS), Dissolved Oxygen(DO), Biochemical Oxygen Demand (BOD), Chemical oxygen demand (COD), Chloride, Sulphate and Heavy Metals (Cr, As, Cu, Pb, Cd, Hg , Zn and Ni) to determine its water quality status in term of water quality index (WQI). In this study it is shown that water quality status of Hindon River deteriorated from very poor to unsuitable for drinking and agricultural practices.  Additionally its effect on the germination of Vigna radiata, Vigna mungo & Triticum aestivum was investigated by treating with different concentrations 0% 25%, 50%, 75%, and 100%. It was found that concentration of 25% and 50% has stimulatory effects on germination rate, germination rate, seedling length, seedling vigour index and further increase in concentration beyond 50% showed inhibitory effects even on initial growth of these three plants. There was significant (at p≤0.05) differences in seed germination rate, root length, shoot length, fresh & dry weight and vigour index at different concentration of River water.
