Abstract EN

A Field experiment was conducted in the Agricultural Research Station at Basrah governorate in Al-Burgisia site during the winter season of 2001-2002 to study the effect of five plant spacing (10, 20, 30, 40, 50) Cm and number of plant per hill (1, 2, 3) plant on growth and yield of safflower (Carthamus tinctorius L.

CV.

Gilla).

A Split plot design were used with four replicates and the result showed the following : Increase number of plant per hill reduced the the number of bells per plant, number of seeds per bell, weight of 1000 seeds and plant yield.

Increase the spacing between plants had significant effects on plant height, plant No.

of branch, number of bell per plant, number of seeds per bell, weight of 1000 seeds and plant yield.

Significant effect were found to the interaction of the two factor on all the studies characteristics excepted on number of branches per plant and bell diameter.
