This study was conducted in the winter season 2012-2013at Ba'shiqah / Tobzawh village (25 km) east of Mosul and farm of the Colleg of Agriculture and Forestry University of Mosul, and both regions are located within the semi-arid areas belt ran where 300-350 mm per year. The study included experiment at each To study the effect of sowing rates 120 and 140 kg / ha in holds pills five varieties of oats (ICARDA Tall ,Possum ,Mitika ,Kangaroo and ICARDA Short, The experiment carried out according to the system of split plot desing in Randomized Complete Blok three replicates The most important results, including the following: more The two varieties Kangaroo and ICARDA Short surpes other varietis grain and straw at both Locations percentage of crude protein in the grain and straw varieties of oats did not differ significantly with each other in this study Seeding rates significantly. affected and flag leaf area number of spike / m2 and number of grains spike thousandth Grain weight at college Lacation only. While the number of days from sowing to maturity yield grain and straw yield percentage of protein in the grain and straw were not significantly affected at both Locations this interction between varieties and seeding rates significantly affected all studied characters except the percentage of protein in the straw in my study and number of spikes/ m 2 and the percentage of protein in the grain at college Location.
