The experimental work was carried out through 2018 at laboratory of agriculture engineering department, faculty of agriculture Tanta University, Egypt to investigate physical properties of the American soybean seeds and Ambrosia weed were imported to Egypt. These properties can be used in design and development of handling, transporting storage and separating equipment. The seeds dimensions tested under four different moisture content 10, 12, 14, and 16% (wet basis). The results showed, the change in moisture content from 10 to 16% the average dimensions of soybean seeds were changed respectively, the length from 5.60 to 6.57 mm, width from 4.91 to 5.73 mm, thickness changed from 4.11 to 4.73 mm, volume from 62.13 to 96.13 mm3, geometric mean diameter from 4.83, to 5.62 mm and the arithmetic mean diameter changed from 4.9 to 5.7mm. The differences on sphericity altered from 86.27 to 85.12%. Similarly surface area changed from 21.99 to 29.95 mm2. Also, the average dimensions of ambrosia weed ranged according imported place the length ranged from 5.20 to 7.53mm, width from 2.46 to 4.00 mm, thickness from 1.57 to 2.97 mm, volume from 11.05 to 41.72 mm3, geometric mean diameter from 3.10 to 4.70 mm, the arithmetic mean diameter from 3.10 to 4.70 mm, and sphericity from 50.16 to 70.14 %. Also, surface area ranged from 23.9 to 57.99 mm2. This results revealed the dissimilarities between soybean and ambrosia physical properties that appear in length, width and thickness, this case lead to obstructing separation processes.
