Abstract
Increasing population growth along with the freshwater resources global crisis necessitates the use of unconventional water resources in agriculture, as the largest freshwater consumption, especially in the arid and semiarid areas. In this study, Four Quality of water is evaluated on morphological properties and water productivity of Radish (CV. Cherry Bell). the research was done based on a completely randomized design including 3 replications as pot planting in the Ferdowsi University of Mashhad in Greenhouse conditions, during 2017-2018. In this study, four irrigation regimes existed (freshwater, urban treated wastewater, half alternate, and alternate urban treated wastewater and freshwater). The results showed that effect of different quality of water on a shoot and root fresh weight and Water productivity was significant at 1 percent level (P<0.01), but plant height, root length, root volume, root diameter, and root area was significant at 5 percent level (P<0.05). in this study, all of this parameter increased significantly with irrigation by urban treated wastewater. Half alternate, alternate of urban treated wastewater and freshwater and wastewater has resulted to increase of yield (12.1, 24.9, and 33.7 percent), tuber fresh weight (117.2, 96.6, and 90.6 percent), shoot fresh weight (40.3, 12.7, and 63.5 percent), physical water productivity (70.7, 45.6, and 74.0 percent), but in this treatment, firmness has a decreased (6.6, 2.1, and 14.6 percent), respectively.
