Turmeric (Curcuma longa) is a bright yellow spice from the ginger family known for its colour, flavour, and healing power. People across the world use it in food, textile dye, cosmetics, and herbal medicine.

Nigeria’s climate in Benue, Kaduna, Niger, Nasarawa, Oyo, and Ondo States provides excellent soil and rainfall for turmeric farming.

Why it matters:

• Rising global demand for natural colourants and organic health products.

• Nigerian turmeric is organic, less chemically treated, and preferred in international markets.

• A hectare can yield 15-20 tons of fresh rhizomes, which can become about 3-4 tons of dry turmeric after curing.

• Processed turmeric powder sells for N3,000-N5,000 per kg locally and fetches higher prices in export markets.

Health Benefits at a Glance:

Turmeric has both antioxidant and anti-inflammatory properties, which make it suitable for supporting kidney health, reducing inflammation, and managing degenerative eye conditions, as well as metabolic syndrome. See Johns Hopkins Medicine for the health benefits of turmeric.

It is either in a raw or powdered form when processed. According to Business Insider, India produces 80% of the world’s turmeric. 

Follow this step-by-step guide on land preparation, planting, curing, and export readiness.

Tip 1: Choose the Right Land and Climate

• Best soil: loamy, well-drained, rich in organic matter.

• Avoid waterlogged areas.

• Turmeric grows well where rainfall is 1000-1500 mm annually.

• Suitable states include Benue, Kaduna, Kogi, Oyo, and Ondo.

 Startup estimate:

To start small on one acre, you may need between N300,000 and N450,000, covering land clearing, rhizomes, fertiliser, and labour.

Tip 2: Get Improved Rhizomes

Use clean, high-yield turmeric sets (rhizomes).

Buy from reputable sources like:

• NRCRI Umudike

• IAR Zaria

• Value Seeds Ltd. or Premier Seeds

 Note: Certified seeds yield 20-30% more and resist common diseases.

Tip 3: Prepare and Plant

• Plough or till the land and make ridges 30 cm apart.

• Cut rhizomes into pieces with 1-2 buds each.

• Plant at 30 × 30 cm spacing and cover lightly with soil.

• Mulch with dry grass or leaves to conserve moisture.

• Planting season: Early April-May (just before the rains) is ideal.

Tip 4: Crop Care and Fertilisation

• Weed regularly (every 3-4 weeks).

• Apply organic manure or NPK 15:15:15 after two months.

• Use irrigation during dry spells.

• Apply mulch again after weeding to prevent soil erosion.

Turmeric takes 7-9 months to mature, depending on the variety and region.

Tip 5: Harvesting

• When the leaves turn yellow and dry, the crop is ready.

• Carefully uproot the rhizomes to avoid bruising.

• Clean off soil and separate mother rhizomes (for replanting) from finger rhizomes (for curing).

Tip 6: Curing and Drying

Curing transforms fresh turmeric into the dry, golden spice used in food and medicine.

1. Boil: Boil rhizomes for about 45 minutes until they soften and emit a strong aroma.

2. Dry: Spread on clean mats or trays under sunlight for 10-15 days until fully dry.

3. Polish: Rub or use a polishing drum to remove the outer skin.

4. Grind: Crush into fine powder and sieve.

5. Store: Keep in airtight, moisture-free containers.

 From one ton of fresh turmeric, expect about 200-250 kg of dry turmeric after curing and drying.

Tip 7: Packaging and Value Addition

To sell or export turmeric:

• Pack the food in 25 kg moisture-proof bags.

• Label with batch number, origin, and date.

• For added profit, process into powder, spice blends, or capsules.

Note: Processed turmeric fetches 40-60% more profit than raw roots.

Tip 8: Export Readiness

Nigeria’s turmeric is gaining traction in India, the UAE, the Netherlands, Germany, and the U.S.

To export successfully:

1. Register with the Nigerian Export Promotion Council (NEPC).

2. Get a Phyto-Sanitary Certificate from the Federal Department of Agriculture and Food Safety.

3. Comply with the Standards Organisation of Nigeria (SON) and NAFDAC requirements for quality and safety.

4. Partner with the Kalabah Export Network to access verified global buyers.

One ton of processed turmeric powder can sell between $1,200 – $1,800, depending on purity, packaging, and quality.

Tip 9: Funding and Support

You don’t have to start alone; several government and financial programs can help:

• Central Bank of Nigeria’s (CBN) Anchor Borrowers’ Programme (ABP)

• Bank of Agriculture (BOA) Agribusiness Loans

• Nigeria Incentive-Based Risk Sharing System for Agricultural Lending (NIRSAL)

Tip 10: Network and Market Access

To stay informed and grow your turmeric business:

• Join the Turmeric Growers Association of Nigeria (TGAN).

• Register with the All Farmers Association of Nigeria (AFAN).

• Attend NEPC export training for packaging and certification guidance.

You can also connect with the Kalabah.com Export Network to reach international spice buyers directly.
