- BARI Turmeric-3: Yields 10,121–12,145 kg/acre.
These varieties feature:
- High Resistance: Resistant to leaf blotch and rhizome rot.
- Vibrant Rhizomes: Deep yellow rhizomes with high curcumin content.
- Adaptability: Suitable for diverse climates and soil types.
Climate and Soil Requirements
Ideal Conditions for Cultivation
- Temperature: Warm and humid climates are ideal.
- Rainfall: Requires consistent rainfall or adequate irrigation.
- Soil Type: Well-drained sandy or clay loam soils.
- pH Level: Maintain a pH of 5.5–6.5 for optimal growth.
Land Preparation
- Plowing: Plow the land 4–5 times to loosen the soil.
- Furrows: Create furrows 20 inches apart to ensure adequate drainage.
- Organic Compost: Add organic compost and adjust soil pH if necessary.
Planting and Seed Management
Planting Season and Preparation
- Best Time: March to April (spring).
- Seed Selection: Use disease-free rhizomes weighing 15–20 grams each.
Seed Treatment and Planting Method
- Fungicide Soak: Soak seeds in fungicide (Bavistin) for 30–40 minutes to prevent fungal infections.
- Planting Depth: Plant rhizomes 5–7 cm deep in rows spaced 50 cm apart.
- Soil Covering: Cover with soil and apply mulch to conserve moisture.
Fertilizer and Irrigation Management
Fertilizer Application Schedule
Per Hectare:
- Compost: 5 tons
- Urea: 220 kg
- TSP (Triple Super Phosphate): 120 kg
- Potash: 220 kg
- Gypsum: 100 kg
- Boron: 2 kg
- At Planting: Apply all compost and half the potash.
- Subsequent Doses: Divide remaining urea and potash into two doses, applied at 70 and 120 days.
Irrigation Techniques
- Soil Moisture: Maintain soil moisture without waterlogging.
- Irrigation Schedule: Provide irrigation during dry periods and ensure proper drainage to prevent water accumulation.
Pest and Disease Management
Common Pests and Control Methods
- Shoot Borer: Damages stems and reduces growth.
- Control: Use Sumithion 50 EC (20 ml/10 liters of water) to manage infestations.
- Thrips: Suck sap from leaves, causing discoloration.
- Control: Employ sticky traps and encourage natural predators.
Common Diseases and Solutions
- Leaf Blotch Disease:
- Symptoms: Dark lesions on leaves.
- Solution: Spray Dithane M-45 (20 gm/10 liters) to prevent damage.
- Rhizome Rot:
- Symptoms: Rotting of rhizomes.
- Solution: Use fungicide-treated seeds and improve drainage.
Harvesting and Post-Harvest Handling
Harvesting Techniques
- Time: 9–10 months after planting.
- Method: Uproot rhizomes gently using tools to prevent damage.
Curing, Drying, and Storage
- Sweating: Pile cleaned rhizomes under shade for 2–3 days to initiate curing.
- Boiling: Boil rhizomes for 45–60 minutes to kill pathogens.
- Drying: Sun-dry rhizomes for 10–15 days until moisture content reduces to 5–10%.
- Storage: Store in well-ventilated spaces with layers of sand or straw to prevent moisture accumulation.
Comprehensive Modern Innovations in Turmeric Grow
Mulching and Mechanization
- Mulching: Use dried leaves or straws to conserve soil moisture and suppress weeds.
- Mechanization: Utilize mechanized tools for planting and harvesting to save time and labor.
Organic Farming Practices
- Vermicompost: Replace chemical fertilizers with vermicompost to enhance soil fertility naturally.
- Bio-Pesticides: Use bio-pesticides to manage pests sustainably, reducing chemical usage.

Eco Grow Tips
Integrating eco-friendly practices into your turmeric cultivation can significantly enhance sustainability and promote environmental health. Here are some eco grow tips to optimize your farming methods:
1. Use Sustainable Enclosures
- Materials: Choose reusable and durable materials such as wood or recycled plastic for constructing enclosures for your turmeric plants.
- Design: Ensure proper ventilation and moisture control within the enclosures to create an ideal growing environment.
2. Recycle Organic Waste
- Kitchen Scraps: Compost kitchen waste such as vegetable peels, coffee grounds, and eggshells to provide additional nutrients for your turmeric plants.
- Garden Waste: Utilize fallen leaves, plant trimmings, and other garden debris to enrich your soil and reduce waste.
3. Maintain Optimal Conditions
- Moisture Levels: Keep the soil consistently moist but not waterlogged to ensure healthy root development and prevent diseases.
- Temperature Control: Protect your turmeric plants from extreme temperatures by providing shade during hot periods and using covers during cold spells.
