It is native to Chad and can also be found in other African countries such as Nigeria and Cameroon. It is a small herbaceous species that has several benefits and is used for various purposes.
Common Names
Aeschynomene tchadica A.Chev. is commonly known as Chad jointvetch or simple joint-vetch. In Nigeria, it is referred to as “Yanyima” in Fulfulde, while in Chad, it is called “Ndoro”.
Appearance
Aeschynomene tchadica A.Chev. is a small herbaceous plant that can reach up to 60cm in height. It has thin stems and leaves that have a greyish-green color. The leaves are pinnately compound and usually have five to eight pairs of leaflets. The flowers are small and yellow and grow in clusters. The fruit is a flattened pod that is about 10cm long and contains several seeds.
Uses
Aeschynomene tchadica A.Chev. has several benefits and is used for various purposes. In Chad, the leaves are cooked as a vegetable and are used to flavor soup and sauces. The stems and leaves are also used as forage for livestock. The plant is also used in traditional medicine to treat various ailments such as diarrhea, dysentery, and respiratory infections. In addition, Aeschynomene tchadica A.Chev. has the potential to be used as a cover crop due to its ability to fix nitrogen in the soil and to improve soil fertility.
Light Requirements
Aeschynomene tchadica A.Chev. requires full sunlight exposure in order to grow optimally. It is a sun-loving plant and does not grow well in shaded or partially-shaded areas. The plant can tolerate some level of shading, but this is not recommended for optimal growth and yield.
Temperature Requirements
The plant is native to West Africa and grows well in tropical and subtropical regions. It requires warm temperatures around 25°C to 35°C (77°F to 95°F) for optimal growth and yield. This temperature range is suitable for the plant during both the day and night. However, the plant can tolerate temperatures up to 45°C (113°F) during the day. Temperatures below 18°C (64°F) are not suitable for its growth.
Soil Requirements
The plant grows well in various soil types such as sandy, loamy or clayey soils. It grows best in well-drained soils with a pH range of 5.0 to 7.5. The plant is tolerant of soil salinity, making it a good candidate for cultivation in arid, semi-arid or saline areas. It is capable of nitrogen fixation through its symbiotic relationship with bacteria, making it suitable for low fertility soils.
Cultivation of Aeschynomene tchadica A.Chev.
Aeschynomene tchadica A.Chev. is a tropical legume that grows in sandy soils. It requires a lot of sunlight. The plant can be grown in pots as well as in a garden. It is frost-sensitive, so in areas where the temperature goes below 5 degrees Celsius, it should be grown in a greenhouse.
Watering Needs
Aeschynomene tchadica A.Chev. requires moderate watering. The soil should be moist, but not water-logged. The plant requires watering once or twice a week in dry weather. Overwatering can lead to problems with the roots, so make sure the soil has good drainage.
Fertilization
Aeschynomene tchadica A.Chev. requires fertilization for optimal growth. The plant requires a well-balanced fertilizer with a ratio of 3:1:2 or 4:1:2 (NPK). Fertilize the plant before flowering and again after the first harvest to encourage regrowth. Too much fertilizer can lead to excessive vegetation and low yields.
Pruning
Aeschynomene tchadica A.Chev. requires pruning to prevent it from becoming too bushy. Follow the one-third rule, which is to remove one-third of the plant's height and width. Cut the branches off above the leaf scar, which is the small ring left behind after a leaf falls off. Also, remove any dead, damaged or diseased branches and stems that may inhibit the growth of the plant.
Propagation of Aeschynomene tchadica A.Chev.
Aeschynomene tchadica A.Chev. is a leguminous plant that can be propagated through both sexual and asexual methods.
Sexual Propagation
The plant produces seeds that can be used for propagation. To obtain seeds, the plant should be allowed to flower and produce seeds naturally. The pods should be left on the plant until they turn brown and dry, at which point they can be harvested and stored until ready for planting.
Before planting, the seeds should be soaked in warm water overnight to soften the hard coat and facilitate germination. The seeds can then be planted directly in well-drained soil or in containers filled with a mix of soil and compost.
Germination usually takes place within one to three weeks, and the seedlings should be watered regularly and kept in a sunny location until they are large enough to be transplanted.
Asexual Propagation
Aeschynomene tchadica A.Chev. can also be propagated through cuttings and division.
Cuttings should be taken from healthy, mature plants during the growing season. The cuttings should be at least 10 cm long, taken from a stem that is not flowering. The cut should be made just below the node, and all leaves except the top two should be removed.
The cuttings can then be dipped in rooting hormone and planted in well-drained soil or in a soilless mix such as perlite or vermiculite. The cuttings should be watered regularly and kept in a warm, humid location until they root.
Division is another option for asexual propagation. This involves dividing the plant into smaller sections, each with its own set of roots. This should be done in early spring when the plant is just beginning to grow. The sections can be planted directly in the soil or in containers filled with a mix of soil and compost.
Overall, Aeschynomene tchadica A.Chev. is a hardy plant that can be easily propagated through both sexual and asexual methods.
Disease and Pest Management for Aeschynomene tchadica A.Chev.
Aeschynomene tchadica A.Chev. is generally considered to be a hardy plant that can withstand various environmental stressors, including pests and diseases. However, there are still some common diseases and pests that can affect the plant. Here are some of the most common ones:
Diseases
Bacterial blight and fungal diseases are some of the most common diseases that affect Aeschynomene tchadica A.Chev. Bacterial blight is caused by the bacterium Xanthomonas axonopodis pv. vignicola and generally affects the leaves, causing them to turn yellow, wilt, or die. Fungal diseases, on the other hand, can cause similar symptoms but are caused by various fungal pathogens such as Fusarium oxysporum or Sclerotinia sclerotiorum.
To manage bacterial blight, infected plants should be removed from the field and destroyed to prevent further spread. Follow a strict crop rotation scheme and make sure to use healthy seed material. For fungal diseases, consider using fungicides that are safe and effective for the plant.
Pests
The most common pests that affect Aeschynomene tchadica A.Chev. are aphids, cutworms, and stem borers. Aphids are small, soft-bodied insects that feed on the plant sap. Cutworms are the larvae of various moth species and can cause damage to the stem by cutting it at the base. Stem borers, on the other hand, are moth larvae that bore into the stem and can cause significant damage to the plant.
To manage these pests, consider using insecticides that are safe and effective for the crop. The use of biocontrol agents such as ladybugs or parasitoid wasps can also be effective. Practice good field hygiene, such as removing crop residues after harvest, and monitor the field regularly for signs of pest infestation.
Overall, proper management of pests and diseases is crucial to the successful cultivation of Aeschynomene tchadica A.Chev. By following proper prevention and control measures, farmers can minimize the impact of these threats and ensure a healthy crop yield.
