Image 1 shows soybeans dried on the stalk.  Soybeans are a palatable high protein, fat and energy feed used for oil production and livestock feed.  Images 2 and 3 show mature soybeans, which occurs when the plant and seed turn a brown color.  Once the plant is mature, 5 to 10 days are needed to dry the seeds to less than 15 percent moisture (>85% DM) for storage.  Image 4 shows the emergence stage of soybean development.  This stage takes approximately 5-10 days.  Soy beans are dicotyledonous, meaning that two leaves emerge during germination.  This occurs when the seed has absorbed at least 50 percent of it weight in water.  The primary root is the first to emerge, and then the stem emerges and grows toward the surface of the soil.  Root hairs are visible; their purpose is to absorb water and nutrients.
