358Following the unplanned urbanization, industrialization, and global population burst, natural water storage is day-by-day experiencing critical crisis worldwide. The generation of contaminated water and its proper treatments has become a major environmental issue. In India, a major agriculture region utilizes wastewater or contaminated water for the irrigation of agricultural lands due to shortage of available fresh water. Present chapter mainly concentrated on the availability and utilization dynamics of wastewater/contaminated water in Indian agricultural sectors. Furthermore, the impacts of wastewater/contaminated water on agriculture crops were catalogued. As the wastewater is a rich source of plant’s requisite organic matter, in many cases wastewater irrigated crops showed higher vigor and yield; but with anomalous physiological and biochemical response. We believe the information catalogued in present chapter should be useful for working in this specific sphere.
