الملخص EN

Field experiment was carried out at in Basrah governorate at Abu-Alkaseb site During 2011- 2012 season to investigate the effect of seeding rates (100,120,140,and 160 Kg.ha-1 ) and number of cutting ( uncut , cut once and cut twice ) and their interaction on some growth characteristics, yield and yield components of Barley.

The experimental design was split- plots to use R.C.B.D design with three replicates, where seeding rates occupied the main plots, while number of cutting Occupied the sub- plots.

The Results was:Number of cutting caused significant increase in all studied characteristics except number of grains per spike.

Cut once caused significant increase in grain yield (261.00 Kg m-2).

Seeding rates showed significant differences in all studied characters except weight of 1000 grain .Seeding rate 120 gave the highest grain yield (237.00 Kg m-2).Interaction between seeding rates and number of cutting was significant in all characters,Cut once with seeding rate120 Kg ha-1 gave the highest grain yield (443.50Kg m-2).
