The use of industrial waste water for irrigation through drip system has emerged a very important way to utilize its nutrients and removal of its pollutants load by cultivating various crops (tomato, brinjal). An experiment was conducted to evaluate the impact of textile factory effluents (0, 10, 35, 75 and 100% concentration) on germination and some physiological parameters like biomass production, root development in vegetable crop. Plants were raised in small pots in triplicate and irrigated with various concentrations (0, 10, 35, 75 and 100%) of effluent. Germination %, biomass production and various attributes of root development were determined in plants grown under different treatments. Plants exhibited a reduction in percentage germination, root and shoot dry weight, number of root branches/plants grown with higher concentration (75 and 100% concentration) of textile effluents. However, the effect of textile effluents was promotive rather than inhibitory on these parameters when applied in low concentrations (10 and 35%). It was concluded that the effect of textile effluent was crop specific depending on the concentration and stage of growth. It was suggested that waste water from textile industry could be utilized for irrigation purposes through drip irrigation after proper treatment and may contribute, at least in part towards solving the problem of disposal of textile effluent. | Effect of textile waste water on seed germination and some physiological parameters in vegetable crop under drip irrigation
