Irrigation with undiluted textile wastewater retards growth and imbalances the ion homeostasis in Amaranthus tricolor
The release of textile effluent into aquatic environments and its subsequent application in agriculture as irrigation water eventually create significant environmental concerns. The study aimed to find potential utilization of textile wastewater (TW) for irrigating red amaranth. The plants were irrigated with undiluted and diluted (50%) TW, and plant growth and nutrient contents were compared with ground water irrigation as a control. The results revealed a notable inhibition in red amaranth growth with undiluted TW application by reducing plant height, fresh weight, and dry weight by 37.03%, 44.83%, and 55.27%, respectively, compared to the control. However, the diluted TW treatment showed no significant alterations in plant height and fresh biomass. Total chlorophyll was reduced by 13.43% and 7.04%, and total antioxidants were reduced by 53.84% and 26.67% in undiluted and -diluted TW-irrigated plants, respectively, compared to the control. The TW irrigation resulted in elevated levels of nitrogen and magnesium in the shoot while concurrently diminishing the concentrations of phosphorus, potassium, and zinc in both root and shoot, as well as reducing calcium content specifically in the shoot. When shifting from control to 50% diluted TW and undiluted TW irrigation, the translocation factor (TF) showed a trend of increasing Mg-TF but a decreasing Ca-TF, combined with a declining K+/Na+ ratio in red amaranth, resulting in an imbalance in ion homeostasis. Therefore, it could be concluded that undiluted textile wastewater is unsuitable for irrigation, but 50% dilution with groundwater minimized the adverse effects of growth and nutrients in red amaranth. Further studies are required to assess the effect of higher dilutions of textile wastewater on crop growth and nutrient acquisition when used for irrigation.
