In addition to its medicinal value, the seeds are used as a source of food. They are roasted and ground to produce a snuff-like powder that is inhaled through the nose. The powder is said to have a calming effect and is used in traditional ceremonies.
The Latisepala Bean is also used in the preparation of food. The seeds are boiled and added to stews and soups to add flavor and nutrition.
The plant has also been found to have an environmental benefit. The roots of Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc. fix nitrogen, which is an essential nutrient for plants. This helps improve the fertility of soils in areas where the plant is grown.
Light Requirements
Rhynchosia procurrens subsp. latisepala typically grows in areas with partial shade to full sun. It can tolerate some shade, but to produce the best growth and flowering, it requires full sun exposure.
Temperature Requirements
This plant thrives in warm weather conditions. It can grow in a range of temperatures from 25°C to 35°C. However, it cannot tolerate frost or extremely cold temperatures, which can kill the plant.
Soil Requirements
Rhynchosia procurrens subsp. latisepala prefers well-drained soil with a slightly acidic to neutral pH level. It can also tolerate a range of soil types, including sandy soils and clay soils. However, it cannot tolerate waterlogged soils, which can lead to root rot and eventually kill the plant.
Cultivation methods
Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc. is a tropical plant that thrives in warm regions with high humidity. It grows well in full sunlight and well-drained soils. The plant requires a lot of space to maximize growth and require support to climb on.
Watering needs
When cultivating Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc., it is important to water it regularly. The plant needs a lot of water to grow well, especially during hot and dry periods, but avoid over-watering as this could cause root rots. Ensure you water the plant at the base to avoid wetting the leaves.
Fertilization
To improve the growth and flowering of the plant, you need to fertilize it regularly. Apply a balanced fertilizer monthly during the growing season to encourage healthy growth. Use well-rotted organic matter, such as compost or manure, and mix this well into the soil before planting. Fertilizer can be broadcasted after planting spearing it away from the stem of the plant.
Pruning
Pruning is essential to eliminate dead and damaged parts of the plant. Cut the stems and branches that are no longer producing leaves or those damaged by pests or diseases. This helps to encourage new growth, bushiness and to increases flowering. Once the plant is established and growing vigorously, it will need a bit of training, this can be supported with sticks and wires.
Propagation Methods for Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc.
Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc. commonly referred to as Wild kidney bean is a woody vine that belongs to the family Fabaceae. The plant is native to Africa, where it grows in woodland and savannah vegetation.
There are two common methods used to propagate Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc.
1. Seed propagation
Seed propagation is a common method used to propagate Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc. The seeds of the plant are easily obtainable and readily available. The seeds can be sown in seedbeds or directly on the ground. To increase the germination rate, pre-soak the seeds in water overnight before planting them in the soil.
The best time to plant Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc. is at the beginning of the rainy season. Germination takes place between 7-14 days after planting. After germination, the seedlings can be transferred to pots or nurseries and nurtured until they reach maturity and are ready for transplanting in the field.
2. Vegetative propagation
Vegetative propagation is another method used to propagate Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc. The woody vine can be propagated through hardwood cuttings. Take cuttings of approximately 30-40 cm in length and remove all the leaves except the top two. Dip the cuttings in rooting hormones and plant them in pots or nurseries. Keep the soil moist and warm after planting to increase the growth rate. Roots will start developing in 3-4 weeks, and the cuttings can be transplanted in the field after 3 months of planting.
Both methods of propagation can be used to propagate Rhynchosia procurrens (Hiern) K.Schum. subsp. latisepala (Hauman) Verdc. However, seed propagation is the most common method used to propagate the plant due to its ease of use and low cost of production.
Disease Management
Rhynchosia procurrens subsp. latisepala is generally a hardy plant that can withstand various diseases. However, some common diseases that may affect the plant are:
- Root Rot: This disease is caused by the fungus Fusarium sp. which causes the plant to wilt and eventually die. To prevent root rot, avoid over watering and poorly drained soil.
- Bacterial Leaf Spot: This disease is caused by the bacteria Xanthomonas campestris. It causes the appearance of small, water-soaked spots on the leaves, which eventually turn yellow and die. Avoid overhead watering and remove infected leaves to prevent the spread of the disease.
- Virus Infections: The mosaic virus and the bean yellow mosaic virus are common viral infections that may affect the plant. These viruses cause distinct mottling and yellowing of the leaves. Unfortunately, there is no known cure for viral infections, so focus on planting disease-resistant varieties or removing infected plants to curb further spread.
Pest Management
Rhynchosia procurrens subsp. latisepala may also be vulnerable to pest attacks. The most common pests that affect the plants are:
- Aphids: These pests feed on the sap of the plant, causing the leaves to curl and appear distorted. To manage aphids, introduce natural predators such as ladybugs or lacewings. You can also use a solution of soapy water to wash the aphids off the plant.
- Spider Mites: These pests suck the sap from the plant's leaves and can cause discoloration and deformation. To prevent spider mites from attacking your plants, ensure a humid environment around your plant by regularly misting the plant. You can also use insecticidal soap or neem oil to manage spider mites.
- Cutworms: These are the larvae of various species of Noctuidae moths. They cut seedlings at the base, causing them to wilt and eventually die. To manage cutworms, make a collar around the base of the plant using cardboard or newspaper. You can also use biological controls such as Steinernema carpocapsae which is a nematode that parasitizes the larvae of the moth.
