Abstract
Rise in population and urbanization increased the fresh water demand and waste water generation. and large gap exist between natural water demand and supply of fresh water. Due to water scarcity and in order to ensure food safety it became important for farmers to search alternate source for irrigation. Efficient use of waste water generated can reduce the stress of water scarcity face by farmers. In this study a pilot field experiment was conducted in which an impact on alteration of micronutrients and heavy metals intake by crops was studied by irrigating Spinach (Spinacia oleracea) and Fenugreek (Trigonella foenum-graecum) with freshwater and treated waste water. The concentrations of micronutrients :- Zinc (Zn),Iron( Fe),Copper( Cu), and Manganese (Mn) and heavy metals :- Cobalt(Co),Cadmium (Cd),Chromium (Cr),Lead (Pb) in spinach & Fenugreek irrigated with domestic treated sewage water was observed below the critical limits. Waste water application showed increased in the yield of crops compared to irrigation with fresh water. If treated properly waste water can encounter the problem of water scarcity and fertilizers. Findings indicate that waste water treated by giving tertiary treatment using phytorid treatment plant can be used for irrigation
