sativa) and sorghum (Sorghum × drummondi) that although not typically recommended for VFS can represent potential extra income if harvested. It is worth mentioning that although these plants are not native, they can be established successfully under these arid conditions if supplementary irrigation is applied during the crucial establishment phase (germination and seedling) ( Bodah, 2013). During the summer, when evapotranspiration is at a maximum and precipitation is negligible, the VFS receives enough water from the irrigation return flows exiting the field to support vegetation maintenance ( Bodah, 2013).
