The experiment was carried out in agricultural research center in Dier Ezzor (Sello Research station) during 2011 growing season to study effect of three different sources of irrigation (river water, well water and alternant irrigation) and three nitrogen fertilization levels (0, 30 and 60 Kg N/ha) on some growth and productivity characters of two atriplex species (A.halimus and A. Numularia). Experimental / design. split-split plots design with three replications. The spices allocated main plots, irrigation resources distributed in sub plot and the nitrogen levels occupied in sub-sub plots. The results showed that atriplex halimas surpassed in most of studied characteristics (plant height , number of shoots per plant, yield of green forage (9.57 to/ha), well irrigation surpassed in (plant height), number of shoots per plant, yield of green forage (9.57 ton/ha) irrigation with river water significantly surpassed in productivity of seeds (1.96 t/ha). While alternitirrigation surpassed in plant height, yield of green forage (7,80 t/ha). number of bads and weight of 1000 seeds. The level of nitrogen fertilization (60 Kg/ha) gave the highest values of plant height, number of shoots per plant, yield of green foraye (8.52 ton/ha), number of bads per plant and seed A yield (1.86 ton/ha) Key words: irrigation source, nitrogen fertilizer, Atriplex.
