A study was carried out in the plastic houses Hort.

Land scape Dept.

college of Agriculture / Tikrit university during growth season 2015-2016 to know effect the date of cuttings olive c.

v Ashrasi on four dates ( 1/11, 15/11, 1/12, 15/12 ).

and three medium growth (sand built, peatmoss and mixed of peatmoss and sand ratio of (1: 1)) in rotting and growth olive cutting, Length of root 7-10 cm.

with two leaves and using concentration of (IBA)( 3000 mg.

Liter-1 ) powder Experiment designed was randomized complete block design (R.

C.

B.

D) as factorial experiment including two factor (12 factorial treatment) with four replication.

Result revealed that The second date of cutting collected as significantly in 15/11 gave highest percentage success of rooting (70.00 % ), and as significantly the four date average rate roots number the in 15/12 (5.64 root /plant-1), average root length root (5.23 cm/root-1), average rate length growth vegetative in 15/12 (3.85cm.

/plant-1) and average rate of leaves number in 1/12 (8.64 leaf/plant-1).

The medium consisting of peatmoss effect as significantly to characteristics studied percentage success of rooting 72.38 % , number of roots5.03 rot/plant-1, length of roots 5.67 cm.

/root-1, length growth vegetative 4.28 cm/plant-1 and number of leaves 9.17 leaf/plant-1.

Therefore, does the overlap between the date of taking the cutting and the type of medium has shown moral influence in the studied traits
