Determination of Some Characteristics Properties of Oil Sunflower Seed

Sunflower seed properties are closely related to yield and quality. therefore, these properties are under the common interaction of genotype and environment, especially affected by factors such as climate and soil structure. the parameters were examined length, width, thickness, 1000-seed weight, the ratio of dehulled/hulledseed weight, ratio of peel, moisture content and oil content of oil sunflower seeds, obtained from commonly oil sunflower produced locations, samsun (bafra, vezirköprü and havza), amasya (merzifon), çorum (center) and tokat (turhal), in central black sea region in 2015 year. the average length, width, thickness, ratio of hull, 1000-seed weight, the ratio of dehulled/hulledseed weight, moisture content and oil content ranged from 10.6 to 11.4, 4.9 to 5.4, 2.6 to 3.3 mm, 12.7 to 26.1%, 49.0 to 65.0 g, 58.7-77.5%, 7.0-8.7% and 41.57-45.67%, respectively. according to these results, oil sunflower seeds produced in samsun-bafra and tokat-turhal locations of the region were found to be better than oil sunflower seeds produced in the other locations in terms of the investigated properties.
