Complete Guide for Turmeric Farming in India
Turmeric (Curcuma longa) is one of the most important spice crops of India and is deeply connected with Indian culture, cuisine, medicine, and agriculture. India is the largest producer, consumer, and exporter of turmeric in the world, contributing more than 75% of global production. For farmers, agriculture students, and agri-entrepreneurs, turmeric farming offers high demand, good price stability, and strong export potential.
This detailed guide explains everything you need to know about turmeric cultivation in India, from land preparation to marketing, in simple and practical language.
Introduction to Turmeric Farming
Turmeric is a long-duration, rhizomatous, herbaceous perennial crop, grown mainly as an annual. The edible part is the underground rhizome, which is processed into dry turmeric powder.
- Botanical name: Curcuma longa
- Family: Zingiberaceae
- Crop duration: 7–9 months
- Suitable for: Small, medium, and commercial farmers
Turmeric can be cultivated under irrigated, rainfed, and organic farming systems.

Lakadong turmeric is famous for very high curcumin content and export value.
Land Preparation
Proper land preparation ensures good rhizome development.
Steps
2–3 deep ploughings
Fine tilth preparation
Formation of:
- Raised beds (for heavy soils)
- Ridges and furrows (for irrigated areas)
Organic Matter Application
- FYM or compost: 10–15 tons per hectare
- Neem cake: 250 kg/ha (recommended)
Seed (Rhizome) Selection and Treatment
Seed Selection
- Use healthy, disease-free mother rhizomes
- Weight: 20–30 g per rhizome
- Avoid shriveled or infected rhizomes
Seed Rate
| Area | Seed Rate |
|---|---|
| Per acre | 800–1000 kg |
| Per hectare | 2000–2500 kg |
Seed Treatment
Organic Treatment
- Trichoderma viride: 10 g/kg seed
- Cow dung + cow urine slurry
Chemical Treatment
- Mancozeb 0.3% for 30 minutes
- Dry in shade before planting
Sowing Time and Method
Sowing Season in India
| Region | Sowing Time |
|---|---|
| South India | May – June |
| Central India | June – July |
| North India | June |
| Rainfed areas | With onset of monsoon |
Spacing and Planting
| Method | Spacing |
|---|---|
| Beds | 30 × 25 cm |
| Ridges | 45 × 20 cm |
- Plant rhizomes 5–7 cm deep
- Cover with soil and mulch
Nutrient Management
Organic Nutrient Management
| Input | Quantity (ha) |
|---|---|
| FYM/Compost | 15–20 tons |
| Vermicompost | 2 tons |
| Neem cake | 250 kg |
Biofertilizers:
- Azospirillum
- Phosphobacteria
Inorganic Fertilizer Schedule
| Nutrient | Quantity (kg/ha) |
|---|---|
| Nitrogen (N) | 120 |
| Phosphorus (P) | 60 |
| Potassium (K) | 120 |
Apply in 3 split doses:
- Basal
- 60 days after planting
- 120 days after planting
Irrigation Management
Irrigation Schedule
| Crop Stage | Interval |
|---|---|
| Initial stage | Every 7 days |
| Vegetative | Every 10–12 days |
| Rhizome development | Every 8–10 days |
| Maturity | Reduce irrigation |
Water-Saving Methods
- Drip irrigation
- Mulching with straw or leaves
- Raised beds for drainage
Weed Management
Weeds compete for nutrients and reduce yield.
Methods
Manual
- 2–3 hand weedings
- At 30, 60, and 90 days
Mulching
- Paddy straw
- Green leaves
- Plastic mulch
Chemical
- Pre-emergence: Pendimethalin (as per recommendation)
Pest and Disease Management (IPM)
Major Pests
| Pest | Symptoms | Control |
|---|---|---|
| Shoot borer | Drying of shoots | Neem oil, pheromone traps |
| Rhizome scale | Yellowing | Neem cake, systemic insecticide |
Major Diseases
| Disease | Symptoms | Control |
|---|---|---|
| Rhizome rot | Wilting, rotting | Trichoderma, good drainage |
| Leaf blotch | Brown spots | Copper fungicide |
| Leaf spot | Yellow patches | Mancozeb spray |
Integrated Pest Management (IPM) is recommended.
Intercultural Operations
