In this study tannery effluents were physicochemically analyzed and their effect on seed germination and seedling growth of some important crops like wheat, jowar, maize, black gram, green gram, red gram, lentil and horse gram was analyzed. The effluent showed beneficial results at lower concentration (20%, 40%) but inhibitory effects at higher concentration (60%, 80%, 100%). Increase in effluent concentration showed decrease in seed germination and shoot elongation. Different physicochemical factors like PH, color, Odour, temperature, DO, BOD, COD, total solids of the effluent were also analyzed. It was found that values obtained were apart from optimum that requires preventing pollution of water bodies after effluent addition. It is concluded that if properly treated and diluted effluents are used for crop growth, the problem of disposal of effluents and also irrigation water needs can be solved.
