Abstract: 
Regarding to the importance of Pistatia atlantica in Zagros forests and its various usages this study was established to improve the ecological knowledge of this species in Garize nursery in Sanandaj. In this experiment completely randomized with factorial design with three treatments include sowing time (January 9th, January 29th and February 19th), sowing depth (surface, 4 cm depth, 8 cm depth) and weed (weed and non weed) with three replicates and five seedling in each row were used. In the end of first growing season determined that January 9th and January 29th sowing times increased the collar diameter whereas did not have any significant influences on survival, height, shoot/root length ratio and shoot/ root dry weight ratio. 4 cm sowing depth treatment increased collar diameter and survival and decreased stem to root dry weight ratio whereas did not have any influence on other parameters. Weed treatment only have the significant influence on stem to root dry weight ratio and it could reduce this parameter. Interactions of three treatments indicate that the usage of weed, 4 cm sowing depth and January 29th sowing time result in the best results.
