Description and Ethnobotany
| Growth Form | Annual herb up to 2 m tall, but cultivars are commonly 0.3-0.9 m tall. |
|---|---|
| Foliage | The leaves are pinnately trifoliate and are alternately arranged along the stem. The leaflets are green and have net venation, an entire margin and a mucronate leaf apex. The leaves are covered with a thin layer of hairs. |
| Flowers | The white to purple flowers are borne on irregular racemes which originate from the axillary buds on the stems. |
| Fruit | The fruits are pods or legumes which turn from green to yellow-brown in colour when ripe. Each pod yields 2 to 3 seeds. When the ripe beans are ready for harvest, the leaves will start to fall off, leaving the brown stems and the pods. |
| Cultivation | It is ideally grown under full sun and in well drained fertile soil. It can also be grown in acidic soil. When grown in rows, a distance of 5cm to 2.5cm in between the seeds would be ideal. Close spacing encourages the growth of the plants and helps in the control of weeds. Harvest the pods by cutting of the plants at ground level. |
| Ethnobotanical Uses | Edible Plant Parts : Edible Seeds Food (Fruit & Vegetable): Soybean is one of the world's most important sources of food and protein. The processed seeds give soy milk, a valuable protein supplement as well as other soy food stuffs such as soy beancurd. Soy sauce is made from matured fermented beans. Soybean is also eaten cooked as a vegetable. Agriculture - Forestry: Soybeans are planted as a cover crop which suppresses weeds. Others: Soy meal is also used as protein-rich animal fodder. |
