Wheat is the main cultivated crop in the LKRB (mainly the Dashte- Azadegan plain). Its average yield is 1500 kg/ha (Agricultural Statistics 2004). Irrigation management practices are traditional and the region suffers from poor water management, which is partly due to lack of modern irrigation infrastructure and improved on-farm activities. Therefore, sound and adoptive solutions are necessary to ameliorate this condition.

Salt-prone land and water resources are major impediments to the optimal utilization of crop production systems in many arid and semi-arid regions of the world, including Iran (Alizadeh et al. 2004; Moghaddam and Koocheki 2004). The salinization of land and water resources has been the consequence of both anthropogenic activities (causing human-induced or secondary salinity and/or sodicity) and naturally occurring phenomena (causing primary fossil salinity and/or sodicity) (Ghassemi et al. 1995).
