Soybean germination begins with the seed imbibing (absorbing) approximately 50% of its weight in water followed by the development of the radicle (primary root) and emergence of the cotyledons (seed leaves). Planting into a moist seedbed with good seed-to-soil contact is important for optimal germination.
