Abstract Population growth, urbanisation, better housing conditions, and economic growth have all contributed to a rise in the volume of wastewater produced by home, industrial, and commercial sources. Millions of small-scale farmers in urban and peri-urban areas of developing countries rely on wastewater or wastewater-polluted water sources to irrigate crops. A pot experiment with sunflower and toria crops under different wastewater and freshwater ratios was studied with two methods viz cyclic and mixing irrigation methods. Results showed that in sunflower head diameter, 1000 achene weight, number of achenes per head and head weight and test weight was 13.6%,22.7%,6.3%,55.2% and 52.4% higher in T5 (100% wastewater irrigated) than T1 (100% freshwater irrigated). A similar trend was observed in toria where yield under T5 was 35% higher than T1. Water productivity and other yield attributes were also higher under T5 treatments. The result indicates that in peri-urban areas wastewater can be used as an alternative source of irrigation but an analysis of wastewater for its safety must be done before using it for irrigation purposes.
