The left image is of soybeans at the early pod stage of growth, when the plant can be used as forage.  Soybean hay can be produced from both oil and hay strains of soybeans, and is a palatable feed adaptable to many growing factors including climate, soil type, and planting date.  Both the pods and forage section of the plant provide digestible protein, which increases as the plant matures.  For maximum energy and protein it should be harvested when there is 90% pod fill or about 1/3 of the plant is in seed.  Soybean forage can be ensiled at these stages, but when ensiled alone it tends toward a butyric fermentation.  To prevent this soybean forage should be ensiled in combination with a readily fermentable carbohydrate source such as corn or molasses.  The middle image is a close up of the flowers, which are very small and located at the junction between stems, 2-4 seeds are produced in the pods.  The right image is the harvesting of soybeans using a combine, which harvests and threshes in one machine.  The combine consists of reels that keep the grain standing up then a cutter bar that cuts the plant stems, which are then fed into the threshing machine.  The grain then enters a hopper to be unloaded directly into a truck.
