Abstract: 

Post harvesting processes such as cleaning, washing, handling, weighing and complementary and conversion processes carried out base of mechanical and physical properties of product. In this research determined dimensional characteristics and components such as arithmetic diameter, geometric diameter, sphericity, bulk density and angle of repose of six varieties of cotton seed. Studied varieties included Sahel, Sephid, Golestan, Armaghan, 43200 and B-557. The data was analyzed by JMP software in CRD, and the graphs were drawn by Excel software. The largest and the smallest arithmetic and geometric diameter were belonged to 43200 and Armaghan respectively. Armaghan cultivar had a biggest sphericity (0.63). Golestan cultivar had the thickest skin, and the highest density was belonged to 43200. Maximum angle of repose (22o) was shown in Sephid cultivar, and the lowest angle of repose (18o) was measured in Armaghan cultivar.
