Mitigating the III Effects of Wastewater on Environment in a Profitable Manner

A pot experiment was carried out in the green house to investigate the effect of thermal power plant wastewater (TPPW), sewage wastewater (SW) and ground water (GW) on Vigna mungo (L.) Hepper (Black gram) cv, PU-19. In addition, its requirement of inorganic fertilizer dose was also evaluated to ascertain the feasibility of fertilizer economy under wastewater application. Wastewaters met the irrigational quality requirements, as most of the chemical characteristics were within the permissible limits. Both TPPW and SW proved equally beneficial for vegetative growth, physiological characteristics and yield attributes including seed yield as compared to GW. Significantly the effect was more pronounced when wastewater grown plants were supplemented with low fertilizer levels. However, seed protein content remained unaffected under the wastewater application.
