Propagation of Lonchocarpus goossensii Hauman
Lonchocarpus goossensii Hauman, also known as "dawa-dawa" in Nigeria, is a perennial plant commonly found in the West African region. The plant belongs to the family Fabaceae and is known for its economic and medicinal values. Lonchocarpus goossensii Hauman can be propagated by various methods, including:
Seed Propagation
Seed propagation is the easiest and most common method of propagating Lonchocarpus goossensii Hauman. The seeds of the plant are readily available and can be obtained from mature pods. The seeds are then sown directly into a well-prepared seedbed or potting soil. It is important to ensure that the soil is kept moist and well-drained to promote germination. Seed propagation is recommended during the rainy season when there is adequate moisture to support seedling growth and establishment.
Cuttings Propagation
Cuttings propagation involves the use of stem or shoot cuttings obtained from mature plants. The cuttings should be about 10-15 cm in length, and the leaves on the lower part should be removed. The cuttings are then dipped in rooting hormone and planted in well-drained soil or sand. The soil should be kept moist, and the cuttings should be protected from direct sunlight and strong winds until they develop roots.
Division Propagation
Division propagation involves the separation of the plant into smaller portions, each with its own root system. This method is suitable for mature plants that have developed a large root system. The plant is carefully dug up, and the root system is gently separated into smaller pieces with a clean and sharp knife. Each division should have at least one stem and a healthy root system. The divisions are then replanted in well-prepared soil and watered regularly until they are established.
Propagation of Lonchocarpus goossensii Hauman can be achieved using any of the above methods or a combination of all methods. It is important to note that the success of propagation depends on several factors such as soil type, moisture, temperature, and sunlight.
