Abstract :

The present study was conducted to analyse the impact of combined industrial effluent on Phaseolus vulgaris L. A pot culture experiment was conducted to study the effect of combined industrial effluent collected from the drain of industrial area of Kathua. The different concentrations (25%, 50%, 75% and 100%) of combined industrial effluent were used for irrigating the crop plants and tap water was used in control set. The effluent showed unpleasant odour, alkaline pH, and high concentration of chlorides. The various parameters studied were percentage seed germination, root length, shoot length and chlorophyll content in the crop plants. The study demonstrated that the lower concentrations of the industrial effluent caused a positive impact on seed germination, growth and chlorophyll content of Phaseolus vulgaris L. However at higher concentrations of the effluent, toxic effects were observed from 20th day onwards. This suggested that the effluent could be used safely for Phaseolus vulgaris cultivation only after proper treatment and dilution.
