Abstract	The present study deals with the effect of sugar mill effluent on seedling growth of Acacia ferruginea DC. The sugar mill effluent was collected near Sakthi Sugars and Chemicals Limited, Padamathur, Sivaganga district, Tamil Nadu. The effect on various growth and biochemical parameters have been estimated at different concentrations of sugar mill effluent (10%, 20%, 30%, 40% and 50%). The results showed that the application of different concentrations of sugar mill effluent on the 45th day of treatment resulted in a significant decrease in growth characteristics of Acacia ferruginea DC compared with the control. The physico-chemical parameters of sugar mill effluent indicated that some parameters, such as pH, EC, acidity, TDS, TS, BOD, COD, sulphate, magnesium, nitrogen, zinc, iron, copper, lead, manganese and oil and grease exceeded the permissible limit compared to Tamil Nadu Pollution Control Board (TNPCB), and then germination and growth parameters increased in lower (10%) concentration of sugar mill effluent, and these morphological parameters gradually decreased with increasing effluent concentration. But the sugar mill effluent affected the plants on the 45th day the plants of Acacia ferruginea DC seedling growth of shoot length, root length, fresh weight, dry weight, vigor index and biochemical contents viz., pigment content carbohydrates, and protein were significantly decreased compared with the control. The sugar mill effluent leads to a decrease in the various growth parameters such as the root and shoot of the seedlings. The reduction in all growth characteristics and biomass accumulation was parallel to a decrease in carbohydrate, protein and nucleic acid, peroxidase, catalase and leaf nitrate activity of the leaf and an increase in the anthocyanin and L-proline. Finally, it was observed that the effluent can be used for irrigation purposes after appropriate dilution with groundwater.
