The study was conducted to investigate some physical properties of soybean at various moisture levels. The dependence of physical properties of soybean on moisture content was determined. In the moisture range from 9.98- 27.10% (wb).The soaked soybean size increased linearly in length (6.34 - 8.95 mm), width (5.42 -6.50 mm), and thickness (4.23 - 5.35 mm) according to final moisture content. In this study, length, width and thickness models based on moisture content are defined as linear models and the regression coefficients (R2 ) related to these models are found between 0.84, 0.72 and 0.
