how to plant achi

Achi (Brachystegia eurycoma), a leguminous tree native to tropical Africa, is a valuable plant used for its seeds in traditional soups and dishes. 

Known for its thickening properties and nutritional benefits, 

This article will guide you on how to successfully plant Achi, from selecting a location to managing pests and diseases.

Description of the Achi (Brachystegia Eurycoma) Plant

Achi (Brachystegia eurycoma) is a perennial, medium-to-large tree that thrives in the tropical regions of West Africa. 

It can grow up to 30 meters in height with a large, spreading canopy. 

The tree produces flat, pod-like fruits that house several round, hard seeds. 

These seeds, once dried and processed, are widely used as food thickeners.

Achi trees are drought-resistant and well-suited to Nigeria’s climate, particularly in the southeastern regions. 

In addition to culinary uses, the tree also offers ecological benefits like soil improvement due to its nitrogen-fixing properties.

Planting Season for Achi (Brachystegia Eurycoma)

The ideal planting season for Achi in Nigeria is during the early rainy season, typically between April and June. 

This period ensures that young seedlings benefit from consistent rainfall, which is essential for germination and early growth. 

Avoid planting during the dry season, as water scarcity may hinder successful establishment.

Planting Achi (Brachystegia Eurycoma)

Step 1: Choose a Location

Select a location with the following characteristics:

  • Climate: Achi thrives in tropical climates with moderate to high rainfall.
  • Soil: Choose well-drained, loamy soils rich in organic matter. The soil pH should range between 6.0 and 7.0.
  • Space: Ensure ample space for the tree to grow, as it requires an extensive root system and canopy.

Step 2: Land Clearing and Preparation

  • Clear the land of weeds, shrubs, and debris to minimize competition for nutrients.
  • Use organic manure or compost to enrich the soil and improve fertility.
  • Create planting holes about 30-50 cm wide and deep to accommodate the seeds or seedlings.

Step 3: Means of Propagation

Achi can be propagated through seeds or seedlings. 

Seed propagation is more common as the seeds are readily available. 

However, ensure you use mature and viable seeds for better germination rates.

Step 4: How to Plant Achi (Brachystegia Eurycoma) from Seed

  1. Seed Preparation:
    • Harvest mature Achi pods and extract the seeds.
    • Soak the seeds in warm water for 24-48 hours to soften the hard seed coat and enhance germination.
  2. Planting:
    • Place each seed in a prepared hole, ensuring it is about 5-10 cm deep.
    • Cover the seed lightly with soil and press gently to secure it.
  3. Spacing:
    • Space the seeds or seedlings at least 7-10 meters apart to accommodate the tree’s size and prevent overcrowding.

Step 5: Watering

  • Water the seeds immediately after planting to aid germination.
  • During the early growth stage, water regularly, especially in the absence of rainfall. Mature Achi trees require less frequent watering as they are drought-tolerant.

Step 6: Apply Manure

  • Use organic manure, such as compost or poultry droppings, to enrich the soil. Apply the manure around the base of the seedlings, avoiding direct contact with the stem to prevent rot.
  • Repeat the application every 3-6 months during the first two years of growth.

Maturity and Harvest

Achi trees typically take 5-7 years to reach maturity, depending on growing conditions and care. The fruits (pods) are harvested when they turn brown and start to dry.

Harvesting Steps:

  1. Collect the pods manually or use tools to cut them from the tree.
  2. Dry the pods under the sun to make it easier to extract the seeds.
  3. Store the seeds in airtight containers to preserve their quality.

On average, a mature Achi tree can produce 10-20 kilograms of seeds annually.

Pests and Diseases

Achi trees are relatively hardy but can be affected by pests and diseases such as:

  • Insects: Termites, beetles, and aphids may attack young seedlings or leaves.
  • Fungal Infections: Root rot and leaf spot diseases can occur in poorly drained soils.
  • Animals: Rodents and birds may feed on seeds or young pods.

Pest and Disease Control

  1. Preventive Measures:
    • Use pest-resistant varieties of Achi seeds.
    • Keep the planting area weed-free to reduce pest habitats.
    • Ensure proper drainage to prevent fungal infections.
  2. Biological Control:
    • Introduce natural predators, such as birds and beneficial insects, to manage pests.
  3. Chemical Control:
    • Apply neem oil or mild insecticides to combat severe pest infestations.
    • Use fungicides to treat fungal infections, but ensure minimal environmental impact.

How Many Achi (Brachystegia Eurycoma) Plants Can I Grow on an Acre of Land, and What Quantity Can I Harvest?

Number of Plants Per Acre

Given the recommended spacing of 7-10 meters between Achi trees, you can grow approximately 100-150 Achi plants on one acre of land.

Expected Harvest Quantity

Each mature Achi tree produces 10-20 kilograms of seeds annually. 

On an acre of land, you can expect to harvest 1,000-3,000 kilograms of Achi seeds per year, depending on the trees’ health and environmental conditions.

Conclusion

Planting Achi (Brachystegia eurycoma) in Nigeria is a rewarding venture with significant economic and ecological benefits. 

By following proper planting and care practices, you can establish a thriving Achi plantation and enjoy abundant harvests for years to come. 

Whether for personal use or commercial purposes, investing in Achi farming is a step toward sustainability and food security.
