Salinity is one of the major environmental stresses which restricted the plant growth especially in arid and semiarid zones. The effect of saline soil levels stresses on the fodder value of Atriplex leucoclada L. (Chenopodiaceae) determined by growing of plants in the 3 levels of salinity including low, medium and high levels salinity in three replications from 2009 to 2011. The combined statistical analysis results showed that salinity had no effect on phonological stages but had effect on fresh weight fodder, dry weight fodder, seed weight, ash, fat, protein, calcium, phosphor and nutrient unit, so the plant sample in experimental site produced 3735 kg fresh weight and 2058 kg dry weight forage and 4015 Kg seed in the high salinity location. Fresh weight fodder, dry weight and seed weight for three locations was significantly different and reduced the rate of 25 to 40% in the high salinity. Ash, fat and calcium increased in the high salinity location including protein, phosphor and nutrient unit reduced in the high salinity location. Finally, the results disclosed that A. leucocladahas the ability to produce suitable fodder under very high saline media, and considered as highly tolerant halophyte.
Key words: Atriplex leucoclada, saltbush, salinity, fodder value, salt tolerant.
