The possible fertilizer reductions and cost savings for other major crops cultivated in the study area are also computed (Table 8). For mango and chilli, the amount of nitrogen required can be supplemented by the TWW itself. In addition to these macronutrients, TWW also supplements micronutrients such as zinc and iron to the plants, which in turn can increase the crop yield. However, it is necessary to have the proper treatment and monitoring of TWW quality to ensure the required irrigation water quality standards.
