The utilization of salt affected desert for growing some suitable halophytic forage plants irrigated with saline water may contribute in sustainable use of these natural resources as a creative solution to attain environmental sustainability. The chosen plant species were primarily investigated in the green house. They have already been selected for their adaptation features for stress condition such as salinity and drought as well as its nutritional values and palatability by different animal. To accomplish this aim, an experiment was conducted at the Model Farm of National Research Centre, El Tour, South Sinai, Egypt to evaluate the effect of foliar application with different sources of potassium KNO3 (1 g/L), K2SO4 (1 g/L), KH2PO4 (1 g/L) and KCl (1 g/L) in addition to tap water as control on fresh cuttings, total productivity, some physiological aspects and nutritional value of three halophytic plants Leptochloa fusca, Spartina patens, Sporobolus virginicus. grown under drip irrigation system with saline water (EC : 8.7 dSm-1). Significant differences were reported for fresh cuttings and total productivity as well as physiological aspects and nutritional values of the tested plants with superiority to plants sprayed with KNO3. Moreover, successive cuttings have positive impact on soil bioremediation process by decreasing of EC as well as the content of Na+ and Cl- in the soil. All the tested plants can tolerate cutting sex times per year and capable of recovering and maintaining a productive stand. It can be concluded that, Leptochloa fusca, Spartina patens and Sporobolus virginicus seemed to be promising halophytic plants for using not only as a tool for combating desertification in arid and semi-arid regions through depleting soil salts, but also offering a new salt-tolerant forage crops some in new reclaimed salt affected desert.
