Now, new research from the University of South Australia shows that water quality and deficit irrigation schemes each have significant effects on crop development, yield and water productivity – with recycled wastewater achieving the best overall results.
Testing different water sources on greenhouse-grown tomatoes, recycled wastewater outperformed both groundwater, and a water mix of 50 per cent groundwater and 50 per cent recycled wastewater.
