Common Names

Tapura ivorensis has a range of common names including African walnut, Arere, Ijingaboom, and Mkpokonam.

Uses

The plant has important commercial and economic uses. The African walnut timber is highly valued for furniture making, as it is durable and attractive with a reddish-brown color. The nuts from the tree are edible and highly nutritious, containing high levels of protein and minerals, and are a staple food for many communities in the region. The bark is also used in traditional medicine for treating a range of ailments such as stomach disorders, coughs, and skin infections.

General Appearance

The African walnut tree has a tall and straight trunk, with a crown that is round or flattened. The leaves are simple and alternate, with a length of up to 30 cm and width up to 15 cm. The flowers are small and usually white, and the fruit is a woody capsule with several chambers. The nuts are contained inside the capsule and can vary in size and shape, with an average length of 3 - 5 cm.

Light Requirements

Tapura ivorensis Breteler, commonly known as the African rosewood, requires bright but indirect light conditions for optimum growth. Direct sunlight can cause damage to its leaves, while low light conditions slow down the growth process.

Temperature Requirements

The African rosewood thrives in warm temperatures ranging from 20°C to 30°C. Any temperature below 15°C can harm the plant, while temperatures above 35°C can cause leaves to wilt.

Soil Requirements

The soil for Tapura ivorensis Breteler should be well-draining, rich in organic matter, and slightly acidic with a pH range of 5.5 to 6.5. A good drainage system is important as the plant cannot tolerate waterlogged conditions, which can lead to root rot.

Cultivation methods

Tapura ivorensis Breteler is a tropical hardwood tree that typically grows in a wide range of soils. However, it prefers well-drained, moist, and sandy loam soils. It can be grown from seeds, which should be collected from mature trees. The seeds should be cleaned, dried, and stored before planting.

It should be planted in an area with adequate sunlight and sheltered from strong winds. The ideal temperature for the plant is between 20-35°C, and it can tolerate high humidity levels.

Watering needs

Tapura ivorensis Breteler requires moderate watering, especially during the growing season (spring and summer). Young trees should be watered more frequently than mature trees. It is essential to ensure proper drainage to prevent waterlogging. Watering should be reduced during the dormant season (fall and winter) to prevent root rot and fungal diseases.

Fertilization

The plant requires regular fertilization to stimulate healthy growth and development. Nitrogen, phosphorus, and potassium are essential nutrients required by the plant. The application of organic fertilizers, such as compost, manure, or leaf mold, can be beneficial. Fertilization should be done at the beginning of the growing season (spring) and repeated every four to six weeks until the end of summer. Avoid over-fertilization as it can lead to the accumulation of salts in the soil and damage the plant roots.

Pruning

Regular pruning is necessary to maintain the shape and size of the tree. It is best to prune the tree during the dormant season (late winter). Remove any dead, damaged or diseased branches, as well as any that are crossing or rubbing against each other. Cutting back one-third of the branches can rejuvenate the tree, but it is essential to avoid pruning too much or too often, as it can weaken the tree.

Propagation of Tapura ivorensis Breteler

Tapura ivorensis Breteler, also known as African walnut or Samba, is a tropical evergreen tree that belongs to the family of Dipentodontaceae. It is native to West and Central Africa and is widely cultivated for its edible nuts, timber, and medicinal properties. Propagation of Tapura ivorensis can be done through various methods.

Seed Propagation

Propagation through seeds is the most common method used for Tapura ivorensis. The seeds of the plant are large and distinctively shaped, with a hard outer shell. The seeds should be collected from mature and healthy trees during the fruiting season. The outer shell of the seed should be broken, and the seed should be soaked for 24 hours to soften the seed coat. Seeds should then be sown in a nursery bed or pot filled with well-draining soil and kept moist. Germination of seeds takes about 2-3 weeks.

Cuttings

Propagation of Tapura ivorensis can also be done through stem cuttings. Cuttings are taken from mature trees during the dormant season. The cuttings should be about 30-45 cm long and should have at least two nodes. The cuttings are then treated with a rooting hormone to stimulate root growth. The cuttings should then be planted in well-draining soil and kept moist. The success rate of propagation through cuttings is lower than that of seed propagation.

Air Layering

Air layering is another propagation technique that can be used for Tapura ivorensis. This method involves stripping away a section of bark from a mature branch and applying a rooting hormone to the exposed area. A ball of moist sphagnum moss is then wrapped around the area and covered with plastic. Roots should develop within 8-12 weeks. Once the roots are established, the branch can be cut from the parent tree and planted in a well-draining soil.

Grafting

Grafting can also be used to propagate Tapura ivorensis, but this method is less commonly used. The technique involves joining a stem or bud from a desired cultivar onto a rootstock of a closely related plant. Grafting is commonly used to produce trees that have the superior characteristics of both the scion and rootstock.

In conclusion, Tapura ivorensis can be propagated through seeds, cuttings, air layering, and grafting. The method chosen will depend on the resources available, time frame, and desired outcome.

Disease and Pest Management for Tapura ivorensis Breteler

Tapura ivorensis Breteler is a plant that is native to West Africa and is commonly used in reforestation projects, agro-forestry, and as an ornamental plant. While this species is generally hardy, it is not immune to various pest and disease problems. It is important to monitor the plant regularly to identify any issues and take appropriate measures to prevent further damage or spread of pests and diseases.

Common Diseases

Tamura ivorensis Breteler is known to be susceptible to various fungal and bacterial infections. Some common diseases that affect this plant include:

• Leaf Spot: Leaf spot is a fungal disease that results in the formation of small, circular spots on the foliage. The spots usually start on the lower leaves and progressively spread to the upper leaves. To control leaf spot, prune infected leaves and destroy them. Apply a fungicide if necessary.
• Anthracnose: Anthracnose is another fungal disease characterized by dark-colored lesions on the leaves. Infected leaves often turn yellow or brown and fall off prematurely. Remove infected parts and apply a fungicide to control the disease.

Common Pests

Various pests can also damage Tapura ivorensis Breteler, the most common ones being:

• Caterpillars: Caterpillars are known to feed on the leaves of Tapura ivorensis Breteler, causing serious damage to the foliage. Use pesticides or biological control agents such as parasitic wasps and predatory insects to control caterpillars.
• Scale Insects: Scale insects are common in Tapura ivorensis Breteler. These insects feed on the sap of the plant, causing yellowing, premature dropping of foliage, and death in severe cases. Use horticultural oil or insecticides to control scale insects.

Overall, it is important to maintain good plant health by providing the right environmental conditions and taking preventive measures. When pest or disease problems occur, early detection and prompt control measures are essential to prevent further damage and maintain the aesthetic and economic value of the plant.
