How To Plant Velvet Tamarind (Nchichi)
Velvet tamarind, locally known as nchichi in Nigeria, is a valuable fruit tree rich in vitamins, minerals, and antioxidants.
It’s celebrated for its distinct sweet-tart flavour, medicinal properties, and various culinary uses.
Cultivating velvet tamarind can be a rewarding endeavour, both for home gardens and commercial farming.
Here’s a comprehensive guide on how to plant, care for, and harvest velvet tamarind in Nigeria.
Description of a Velvet Tamarind (Nchichi) Plant
The velvet tamarind (Dialium guineense), commonly known as nchichi in Nigeria, is a small to medium-sized tree with dark brown to black bark and delicate foliage.
It produces small, round fruits with a velvety outer shell and an inner pulp that is orange and tangy-sweet in taste.
Velvet tamarind trees thrive in tropical regions and are drought-tolerant, making them well-suited to Nigeria’s varied climate zones.
The tree’s wood is valuable for timber, and its leaves, bark, and fruit have been traditionally used in African medicine to treat various ailments, including malaria, wounds, and digestive issues.
Planting Season for Velvet Tamarind (Nchichi)
In Nigeria, the optimal time to plant velvet tamarind is at the onset of the rainy season, typically between April and June.
The rains provide adequate moisture for seed germination and young plant establishment.
Planting at this time also ensures that the trees will benefit from consistent rainfall, which helps them grow robustly during their initial stages.
Planting Nchichi (Velvet Tamarind)
Step 1: Choose a Location
Select a well-drained, sunny location for planting velvet tamarind.
The tree grows best in sandy-loamy soils with good drainage, as waterlogged conditions can damage roots.
Additionally, the site should have adequate sunlight to encourage healthy growth and fruit production.
Step 2: Land Clearing and Preparation
Before planting, clear the land of weeds, stones, and debris.
Properly loosen the soil by tilling it to a depth of at least 30 cm.
This will promote root penetration and aerate the soil, making it easier for young plants to establish themselves.
Add organic compost or well-rotted manure to enrich the soil with nutrients.
Step 3: Means of Propagation
Velvet tamarind can be propagated through seeds or vegetative methods, such as stem cuttings.
However, seed propagation is the most common and reliable method in Nigeria due to its simplicity and effectiveness.
To grow trees that closely resemble the parent plant in quality, it’s essential to select healthy, mature seeds for planting.
Step 4: How to Plant Velvet Tamarind (Nchichi) from Seed
- Soak the Seeds: Begin by soaking the seeds in water for 24 hours to soften their hard outer shells and enhance germination.
- Prepare Nursery Beds: Sow seeds in nursery beds or pots filled with loose, nutrient-rich soil. Plant the seeds about 2 cm deep and water lightly.
- Transplanting: When seedlings reach about 20–30 cm in height, transplant them to the prepared field. Maintain a spacing of approximately 5 meters between trees to allow for their spread and optimal sunlight access.
Step 5: Watering
While velvet tamarind is drought-tolerant, young plants require regular watering to establish strong roots.
Water the plants once or twice weekly during the dry season.
Avoid over-watering, as excessive moisture can lead to root rot.
Step 6: Apply Manure
Organic manure or compost should be applied around the base of the young trees to boost nutrient levels.
Adding a balanced fertilizer can also support growth, especially during the first two years.
Apply manure at the beginning of the rainy season, and follow up with a smaller amount toward the end of the rain.
Maturity and Harvest
Velvet tamarind trees typically begin to bear fruit after 4–5 years, depending on soil quality, care, and climate conditions.
The fruits mature from October to March when they are harvested.
Harvesting involves picking the fruits from the tree or collecting them as they naturally fall.
Each mature tree can yield between 40–100 kg of fruit per season, depending on the tree’s age, health, and environmental factors.
Pest and Diseases
While velvet tamarind is relatively resistant to pests and diseases, certain issues can occasionally arise, including:
- Fungal Infections: Common in humid conditions, they can cause leaf spots and root rot.
- Insect Pests: Sap-sucking insects like aphids and leafhoppers may infest young plants, hindering growth.
- Nematodes: Soil-borne pests that can affect the roots, leading to stunted growth.
Regular monitoring and maintenance of the plantation can help detect and manage these issues early.
Pest and Disease Control
- Fungal Infections: Prevent fungal growth by ensuring proper spacing between plants to promote airflow. Use copper-based fungicides if symptoms of fungal infections appear.
- Insect Pests: Natural predators, like ladybugs, can help control aphids. Alternatively, neem oil or mild insecticides can be used to manage insect infestations.
- Nematodes: Rotate crops if nematode infestation is severe, or apply organic matter like neem cake, which helps deter nematodes naturally.
How Many Velvet Tamarind (Nchichi) Plants Can I Grow on an Acre of Land, and What Quantity of Velvet Tamarind Can I Harvest?
On an acre of land, you can grow approximately 160–180 velvet tamarind trees, assuming a 5-meter spacing between each tree.
With an average yield of 40–100 kg per mature tree per season, an acre of velvet tamarind plantation could potentially produce 6,400 to 18,000 kg of fruit per season, depending on tree health, age, and care practices.
Conclusion
Velvet tamarind, or nchichi, is a rewarding crop to cultivate in Nigeria, both for its economic value and environmental benefits.
By carefully following these steps selecting a suitable location, preparing the soil, planting and watering, managing pests, and harvesting you can establish a thriving velvet tamarind plantation.
