Abstract: 

About 15% of Iranian lands are affected by salinity. Species of chenopodiacea family, such as Atriplex canescens is special for planting in this area. This study was conducted from 1993 to 2003 in Nowdehak rangeland station of Qazvin province. objectives of this research were planting density of Atriplex canescens. The statistic design was split split plot (using on CRBC) with three replication. Main plot were density (2x2, 4x4, 6x6 meter), sub plots were pruning period (annual, binnial, triennial) and sub sub-plot were hight pruning (control, complete pruning, 20, 40, 60 heights). Result showed that planting density and pruning had significant effect on forage yield (P<0.01). Planting density 2x2 m had higher yield than others treatments. Complete pruning and pruning 20 cm height had no different yield but produced forage were higher than other treatments. Triennial pruning period was better than anuual and binnial praning priod in respect of forage yield. Generally result showed that in this area and similar zone planting, distance (2x2m) with triennial pruning and complete pruning had maximum forage yield.
