et al., 2005b ; Parsons, 2000 ). Horticultural crops, especially cut flowers, are ideal for use with saline or wastewater reuse irrigation because they are not used for consumption and they are high-value crops. In 1998, 431 operations in the United

Salinity stress is considered one of the most important abiotic factors that limits the productivity of crop plants ( Flowers and Yeo, 1995 ), and the estimated global cost due to salinity is more than $12 billion annually ( Qadir et al., 2008

industry, especially greenhouse growers, has been to use lower quality water and/or greenhouse effluents to irrigate their crops. Many growers have also found applications for saline or degraded wastewaters in their own operations that continue to allow
