The main objective of this research to determine of physical properties of seed related to help in safe passage for seed through cleaning and separation processes. Also investigate some seed properties can be used in design and development of multi-seed planting machine. Soya Bean, Wheat, Corn, Cotton Faba Bean and Sunflowers were tested at department of agriculture engineering, faculty of agriculture, Tanta university, Egypt. through 2022. From the results, it is clear that the little differences in the maximum of Length dimensions between Soya Bean and Wheat were 7.62 and 8.72 mm., it increased between Corn and Cotton to 15 and 10.12 mm. and Faba Bean and Sunflowers were 11 and 19 mm. the maximum of Geometric mean diameter recorded little differences between Soya Bean and Wheat were 2.76 and 2.81 mm., it increased between Corn and Cotton to 4.83 and 5.13 mm. and Faba Bean and Sunflowers were 8.47 and 6.86 mm.
