Impact of Dye Effluent on Seed Germination, Seedling Growth and Chlorophyll Content of Soybean (Glycine max L.)

Textile dyeing industry is one of the major water consuming and high polluting industries in India. Untreated industrial effluent discharged into ecosystem pose a serious problem to the aqua living organisms, plants and human being. Effluent in higher concentration affects the soil and causes heavy damage to crop growth. In the present study effects of dyeing effluent on seed germination and seedling growth of soybean ( Glycine max L. ) has been carried out at different concentration (20, 40, 60, 80, 100 %) of the effluent collected from dyeing industries at Kaithun region, Kota and control was maintained. Seed germination percentage of Glycine max was not significantly affected at 20 % treatment level where as higher concentration of dyeing effluent negatively affects the germination percentage of seeds. Seeding growth (Shoot and Root lengths) and Chlorophyll content (Chlorophyll a and b) have found to increase at 20 % and 40 % of treatment level. The root length was found to increase 4.4 % and 2.2 % and shoot length was found to increase 1.5 % and no change at treatment level 20 % and 40 % respectively than control. Due to increase in concentration of effluent at 60 % treatment level and above a gradual decline of seedling growth was observed. At 100 % treatment level root length and shoot length were decrease 57.7 % and 58.7 % respectively in comparison to control. Chlorophyll content was also adversely affected due to higher concentration of dyeing effluent. The present study revealed that Glycine max L. (soybean) is susceptible to dyeing industrial effluent.
