TURMERIC: DO NOT JUST PLANT IT — DECIDE WHAT INDUSTRY YOU ARE PLANTING FOR
When a farmer sees turmeric, he may see a rhizome.
When an industrial strategist sees turmeric, he should see:
Seed rhizomes → farms → curing → drying → polishing → powder → oil → oleoresin → curcumin → foods → beverages → cosmetics → nutraceutical ingredients → exports.
This is why I keep arguing that Africa must stop measuring agriculture only in hectares.
We should also measure:
How many products?
How many processors?
How many factories?
How many export markets?
How much value remains in the country?
🇮🇳 INDIA'S TURMERIC SCALE
India produced approximately 1.063 million tonnes of turmeric from 293,000 hectares in 2023–24, according to the Government of India.
Evidence:
Government of India — turmeric production and National Turmeric Board Commerce Department
That already tells us something: this is not simply a kitchen spice. It is a significant agricultural commodity.
🌍 INDIA ACCOUNTED FOR ABOUT 66% OF WORLD TURMERIC EXPORT VALUE IN 2024
Government figures based on Spices Board data report:
World turmeric exports, 2024: approximately US$502.74 million
India's exports: approximately US$333.25 million
India's share: approximately 66%
Evidence:
Press Information Bureau / Spices Board — India's contribution to world turmeric exports Press Information Bureau
That is what happens when a country does not merely grow a crop — it develops a market position around it.
📦 INDIA EXPORTED 176,325 TONNES OF TURMERIC IN 2024–25
Official Spices Board figures reported by the Government of India show exports increasing from 162,019 tonnes in 2023–24 to 176,325 tonnes in 2024–25.
Evidence:
Government of India — turmeric export volumes Press Information Bureau
The same source reports approximately US$341.54 million in turmeric export value through the major ports reported for FY2024–25.
Evidence:
Government of India / Spices Board — state-wise turmeric export value Press Information Bureau
🌱 BUT BEFORE EXPORT COMES FARM MANAGEMENT
Tamil Nadu Agricultural University recommends commercial turmeric on friable, well-drained loamy soil and identifies propagation using mother and finger rhizomes.
Its production guidance gives a finger-rhizome seed rate of approximately 2,000 kg/ha, with a cited spacing of 45 × 15 cm for the production system described.
Evidence:
Tamil Nadu Agricultural University — turmeric production technology Agritech TNAU
This does not mean every Botswana farm should mechanically copy those rates.
Our soil, temperature, irrigation regime, cultivar and buyer specifications must determine our final protocol.
That is what professional agronomy means.
💧 WATER AND NUTRITION MUST BE MANAGED AS A SYSTEM
TNAU describes drip irrigation and staged nutrient management extending through establishment, vegetative growth, rhizome initiation and rhizome maturation.
Evidence:
TNAU — turmeric fertigation and crop-stage management Agritech TNAU
A commercial turmeric farmer should therefore record:
Planting date
→ cultivar
→ seed-rhizome source
→ block number
→ irrigation
→ fertilisation
→ crop protection
→ harvest date
→ post-harvest batch
That becomes the beginning of traceability.
⏱️ TURMERIC IS NOT A QUICK CROP
India's Department of Commerce states that turmeric cultivars can take approximately 180–280 days from planting to harvest, depending on variety.
Evidence:
Government of India — turmeric crop duration and sector development Commerce Department
TNAU advises harvesting when the crop reaches maturity and the plants begin lodging, yellowing and drying.

🏭 THEN COMES THE REAL MONEY: VALUE ADDITION
Do not think only:
Fresh turmeric → powder.
ICAR researchers identify value-added turmeric pathways including:
essential oils
oleoresins
nutraceuticals
golden-milk products
turmeric flakes
cosmetics
Evidence:
ICAR — Turmeric: Golden spice to value-added treasure Indian Agricultural Research Journals
🟠 TURMERIC OLEORESIN
India's Ministry of Food Processing Industries identifies turmeric oleoresin as a value-added extract used for colour and aroma in beverages and processed foods.
Evidence:
Ministry of Food Processing Industries — Value Added Turmeric Products pmfme.mofpi.gov.in
🧪 CURCUMIN
The Spices Board identifies curcumin among India's value-added spice products and separately lists turmeric powder, turmeric oleoresin and turmeric oil.
Evidence:
Spices Board India — value-added spice products Indian Spices
This is precisely why choosing the right variety matters.
Some turmeric genetics are developed not merely for tonnage but also for curcumin and oleoresin content.
🌱 HIGH-VALUE VARIETY EXAMPLE
ICAR-IISR's Pragati turmeric is reported at approximately:
38–52 t/ha fresh rhizomes
5.02% curcumin
15.29% oleoresin
about 180 days crop duration
under its stated characteristics.
Evidence:
ICAR-Indian Institute of Spices Research — turmeric varieties and technologies ns1.kvkcalicut.gov.in
Again, Africa's lesson is not to copy a yield figure blindly.
The lesson is:
Breed and select the crop according to the industry you intend to supply.
A buyer wanting high-curcumin raw material may value a crop differently from someone buying ordinary culinary turmeric.
🇧🇼 MY QUESTION FOR BOTSWANA
Why should we stop at:
Turmeric farmer → dried turmeric → exporter?
Why not build:
Nursery / seed-rhizome enterprise
↓
Commercial production clusters
↓
Washing and grading
↓
Curing
↓
Controlled drying
↓
Polishing
↓
Powder milling
↓
Laboratory
↓
Curcumin testing
↓
Oleoresin extraction
↓
Turmeric oil
↓
Food ingredients
↓
Cosmetics
↓
Nutraceutical formulations
↓
Packaging
↓
Export
Now we are no longer discussing turmeric farming.
WE ARE DESIGNING A TURMERIC BIO-INDUSTRY.
That is where I believe Africa must go.
Do not plant a crop and then search for its purpose.
Decide the industry first — then design the crop to feed it.
