| Abstract | ||||
| Various physical properties of radish seeds were determined as indicators during the hole design of the seeder bottom. The principal dimensions (thickness, width, and length), geometric mean diameter, arithmetic mean diameter, seeds surface area, bulk density, true density, sphericity, and porosity were recognized as physical parameters. The results showed that the average physical properties of radish seeds, principal dimensions, sphericity, geometric mean diameter, arithmetic mean diameter, seeds surface area, bulk density, and true density were 2.32±0.126mm, 2.55 ±0.160mm, 3.38±0.169mm, 0.81±0.03, 2.71 ±0.11mm, 2.75±0.11 mm, 54.10 ±4.17 mm2, 0.67 ±0.02g/cm3, and 1.265 ±0.16g/cm3, respectively. The regression analysis showed that the spherical seeds, geometric and arithmetic mean diameters were significant relationships on each seed's length, width, and thickness. The largest diameter and hydraulic areas of radish seeds were equal using holing coefficients K of 1.3 and 1.4 at the bottom open hole diameter of 10 mm, followed by 8.0 mm hole diameter with a coefficient of variation of 4.56 and 6.63%, respectively. | ||||
