California are required to use recycled water for irrigation when available ( Arizona Department of Water Resources, 2008 ; California State Water Resources Control Board, 2010 ). However, excessive salts in recycled water may cause salinity/sodicity damage

Salinity, drought, and heavy metal stresses are the major abiotic stresses affecting the crop production throughout the world ( Ali et al., 2017 ; Osakabe et al., 2014 ; Parihar et al., 2015 ; Rizwan et al., 2016 ; Saifullah et al., 2018

tolerance among these ornamental plants was observed. Depending on salt tolerance, some plants became more compact with little visual damage when irrigated with low to moderate salinity compared with nonsaline control ( Niu and Rodriguez, 2006a , 2006b

Soil salinization is a growing problem throughout the world, particularly in arid and semiarid regions such as the southwestern United States, where saline and/or sodic soils are a common occurrence of irrigated lands. Saline soils can negatively

Currently, salinity affects up to one-third of all irrigated agricultural land worldwide and the areas affected are increasing ( Carter et al., 2005 ; Cassaniti et al., 2009 ; Munns and Tester, 2008 ; Shibli et al., 2007 ). Salinity is
