Propagation of Aeschynomene hockii De Wild.
Aeschynomene hockii De Wild., commonly known as Hock's joint-vetch, is a herbaceous plant species that is native to tropical Africa. The plant is a member of the Fabaceae family and is known for its nitrogen-fixing capabilities, which make it a valuable plant in agroforestry systems. There are several methods that can be employed for the propagation of Aeschynomene hockii De Wild. which are discussed below:
Seed propagation:
Aeschynomene hockii De Wild. can be propagated through seeds. The seeds of Aeschynomene hockii De Wild are small and can be sown directly on the soil surface. Before sowing, it is essential to prepare the site by removing any weeds and loosening the soil to enable the seed's root system to penetrate easily. The seeds should be sown at a depth of 1-2 cm and spaced at least 10 cm apart. After sowing, the site should be watered lightly.
Vegetative propagation:
Aeschynomene hockii De Wild. can also be propagated vegetatively. The plant can be propagated through stem cuttings from the parent plant. The stem cuttings should be taken from healthy plants and should be at least 12 cm long. The cuttings should be planted in a well-prepared site that is free of weeds and debris. The cutting should be inserted into the soil to a depth of approximately 2-3 cm. The site should be watered lightly after planting to ensure the cutting's survival.
Root cuttings:
Aeschynomene hockii De Wild. can also be propagated through root cuttings. This method is commonly used when there is a shortage of seeds or when seed germination rates are low. The root cuttings should be taken from healthy plants, and they should be at least 5 cm long. The cuttings should be planted in a well-prepared site and inserted into the soil at a depth of approximately 2-3 cm. The site should be watered lightly after planting.
Inoculation:
Another method that can be used for propagating Aeschynomene hockii De Wild. is by inoculation. This method involves the use of specific bacteria that form nodules on the plant's roots. The nodules contain bacteria that can fix nitrogen from the air and convert it into a form that is easily absorbed by the plant. The use of inoculation in propagating Aeschynomene hockii De Wild. can increase the plant's yield and improve soil fertility.
