Atriplex planting on March was woody despite of its shoot and root pruning on September. A field experiment was conducted at Khanasri Station to determine two nursery planting dates for three Atriplex species, and evaluate their grazing productivity. The results of current experiment indicated that survival % of A. halimus, A. nummilaria, and A. lecoculada were 95, 71 and 91 %, respectively. While, the planting dates survival % of March and November were 96 and 75 %, respectively. For

While, the interaction between species and planting date had significant differences in plant height, A. halimus, A. nummilaria and A. lecoculada planted on March recorded 55, 54 and 30 cm, respectively. While, on November they recorded 43, 29 and 25 cm, respectively. Also, allowable dry yield were 769, 511 and 287 kg/ha for A. halimus, A. nummilaria and A. lecoculada planted on March, respectively while, they were recorded 427, 224 and 211 kg/ha on November, respectively. We concluded that March planting date is recommended for Atriplex species. Further studies are needed to investigate Atriplex planting date in nursery.
