Crotalaria basipeta is a shrub that reaches a height of about 1-2 meters when fully grown. The plant has several branches and is covered with fine, soft hair on the stems and leaves. The leaves are alternate and about 8-14 cm long with a lanceolate shape. The flowers are yellow with black dots and are borne on erect racemes at the end of the branches. The fruit is a cylindrical pod 2-4 cm long and containing many small seeds.
Common names
Crotalaria basipeta is known by several common names, including African rattlebox, yellow rattlebox, and African laburnum. The name African rattlebox is derived from the sound the seeds make when shaken inside the pod, similar to a baby's rattle.
Uses
Crotalaria basipeta has a wide range of applications in traditional medicine. The plant has been used to treat various human ailments, including fever, respiratory problems, and gastrointestinal disorders. The bark of the plant has also been used to relieve pain. Research has shown that the plant contains several bioactive compounds, including alkaloids, flavonoids, and saponins, that could account for its medicinal properties. Apart from its medicinal use, the plant also has ornamental value and is often used in landscaping.
General appearance
Crotalaria basipeta is an attractive plant with bright yellow flowers that bloom from spring to summer. The plant has a slender, upright growth habit and is covered with soft hair that gives it a velvety appearance. The leaves are green and have a lanceolate shape that tapers at the end. The plant's height, coupled with its bright yellow flowers, makes it an eye-catching addition to any garden.
Light Requirements
Crotalaria basipeta requires full sun to grow properly. It can also tolerate partial shade, but for optimal growth, it is recommended to grow it in direct sunlight.
Temperature Requirements
The plant thrives in warm climates with temperatures ranging from 18 to 32 °C (64 to 90 °F). It can grow in a range of soil temperatures, but temperatures above 40 °C (104 °F) can be harmful to its growth.
Soil Requirements
Crotalaria basipeta prefers well-drained sandy or loamy soil with a pH range of 6.5 to 7.5. It also grows well in rocky or gravelly soils. It is tolerant of moderately saline soil conditions but does not grow well in waterlogged or poorly drained soils.
Cultivation methods
Crotalaria basipeta R.Wilczek is a perennial plant that grows well in tropical and subtropical regions. The plant can tolerate a wide range of soil types, but it prefers well-drained soils with a pH range of 6.0 to 7.5. The plant should be grown under full sunlight and protected from strong winds.
Propagation of the plant can be done by seed or stem cuttings. Seeds should be sown during the rainy season in the nursery bed and transplanted after four to six weeks. Stem cuttings should be taken from mature plants and treated with rooting hormones before planting.
Watering needs
Crotalaria basipeta R.Wilczek requires regular watering, especially during the growing season. The plant should be irrigated once or twice a week, depending on the weather conditions. The soil should be kept moist but not waterlogged. Overwatering can lead to root rot and other diseases.
Fertilization
The plant responds well to organic and inorganic fertilizers. The application of fertilizers should be done at the beginning of the growing season and during the flowering period. Organic fertilizers such as farmyard manure should be used at a rate of 5 to 6 kilograms per square meter. Inorganic fertilizers such as NPK 10:10:10 should be used at a rate of 100 grams per square meter.
Pruning
Pruning of Crotalaria basipeta R.Wilczek is necessary to promote bushy growth and prevent legginess. The plant should be pruned during the early stages of growth to encourage branching. Pruning should be done after the flowering period to remove dead or damaged parts of the plant.
Overall, with proper care and management, Crotalaria basipeta R.Wilczek can thrive and produce bright yellow flowers that add color and beauty to any garden.
Propagation of Crotalaria basipeta R.Wilczek
Crotalaria basipeta R.Wilczek, commonly known as Basiped crotalaria, is a flowering plant from the Fabaceae family. It is native to Nigeria and Cameroon, but it can also be found in other African countries. The plant is known for its yellow flowers and its ability to fix nitrogen in the soil.
There are different methods of propagating Crotalaria basipeta R.Wilczek, including:
Seeds
The most common method of propagating Basiped crotalaria is by using seeds. The seeds should be sown in a well-draining soil mix, with a pH of 6.5-7.5. The best time to sow the seeds is during the rainy season, as the plant requires a lot of water to establish itself. The seeds should be sown at a depth of approximately 1-2 cm and space apart to prevent overcrowding. Germination usually takes 1-2 weeks, and the seedlings should be thinned out once they are a few inches tall.
Cuttings
Basiped crotalaria can also be propagated by stem cuttings, although this method is less common. The cuttings should be taken from mature plants during the growing season. The cuttings should be about 3-4 inches long and should be taken from the top of the plant. Remove the lower leaves and dip the end of the cutting in a rooting hormone. Plant the cuttings in a well-draining soil mix and keep the soil moist until the cuttings establish roots.
Division
Dividing the plant is another method of propagation that can be used for Basiped crotalaria. The plant should be divided during the dormant season, after the flowers have faded. Carefully dig up the plant, and separate it into smaller sections, making sure each section has roots attached. Replant the sections in well-draining soil and water thoroughly.
Regardless of the propagation method used, it is important to provide the plant with adequate water and nutrients to ensure its growth and development. With proper care, Basiped crotalaria can be a beautiful addition to any garden.
Disease Management
Crotalaria basipeta R.Wilczek is susceptible to several diseases, including:
- Root rot: This disease targets the roots resulting in stunted growth and plant death. It can be caused by a fungal or bacterial pathogen. To manage root rot, avoid waterlogged soils and ensure the plant has good drainage.
- Leaf spot: This disease manifests as black spots on leaves and can lead to defoliation. Leaf spot can be caused by bacterial or fungal pathogens. To manage leaf spot, remove infected leaves and ensure adequate ventilation around the plant. Also, avoid watering the plant from above.
- Powdery mildew: This fungal disease presents as a white, powdery coating on leaves and flowers. It can cause distortion of plant tissues and eventual death. To manage powdery mildew, ensure good air circulation and avoid overcrowding of plants. Use a fungicide if necessary.
Pest Management
The following pests may attack Crotalaria basipeta R.Wilczek:
- Aphids: These sap-sucking insects can cause stunted growth, curled leaves and distorted flower buds. To manage aphids, spray the affected plant with a strong jet of water to knock them off. Alternatively, use an insecticidal soap solution.
- Caterpillars: These larvae can defoliate the plant and cause severe damage. To manage caterpillars, pick them off manually if possible. Use a biological control method such as Bacillus thuringiensis (Bt) or a chemical insecticide if necessary.
- Thrips: These small insects can damage the flowers by feeding on their tissues. To manage thrips, remove any infected flowers and use a systemic insecticide if necessary.
