The research work was accomplished at the laboratories of the Field Crops Department, Faculty of Agriculture and Forestry, University of Duhok during the 2013-14 Season. An equation utilizing the Microsoft Excel Program was used to estimate seeding rate based on fixed number and test weight by displacement method in comparison to the common method by Hectoliter apparatus. The results show that 414/m2 are sufficient for most evaluated varieties as compared to Abu Ghraib3 variety which was considered as a check variety; the final seeding rate and seeds number was adjusted according to the actual germination and purity percentages. Results also showed high correlation (r=0.885) and close relationship between both common test weight measurement method and the suggested method by displacement for small samples.
Key words: Wheat, seeding rate, population, test weight.
