EFFECT OF TEXTILE INDUSTRY WASTE WATER ON SEEDGERMINATION AND PLANT GROWTH OF MUSTARDSAVITA RANI, POOJA, NANDNI, KASHISH SHARMA AND SHIVI CHOUDHARYAbstract The assessment of the toxicity of textile waste water is of great concern as most of them exert toxic effects on plants, animals and microorganisms, when released in water stream and used for irrigation purpose on land. During the present investigation, seed germination of mustard was markedly affected by different concentration of waste water. Lower concentrations of wastewater(10%) were not inhibitory to seed germination, while germination rate was poor with 20, 50 and100% waste water concentration as compared to control and the seeds germination was slow at 3rdand 5th day with higher textile waste water. The effect of different levels of textile wastewater under pot house conditions have shown that lower concentrations (10 and 20%) of waste water were not inhibitory to plant growth when irrigated with after germination. However, plant growth was affected drastically at higher concentration of waste water when applied after germination, while with more than 20% waste water concentration, growth was suppressed in both after and regular germination throughout the experiment. |
