• High market demand during festivals and weddings
• Suitable for open field and protected cultivation
• Continuous flowering and harvesting
• Low risk compared to many horticultural crops

Marigold farming in India is practiced commercially in states such as:

• Andhra Pradesh
• Telangana
• Karnataka
• Tamil Nadu
• Maharashtra
• West Bengal

4. Climate and Soil Requirements

Climate

Marigold grows well under tropical and subtropical climates.

Ideal conditions:

• Temperature: 18°C – 30°C
• Requires full sunlight
• Sensitive to frost and heavy rainfall

Best seasons in Andhra & Telangana:

• Kharif: June–July planting
• Rabi: September–October planting

Soil Requirements

• Well-drained loamy soil is ideal
• Soil pH: 6.5 – 7.5
• Avoid waterlogged soils

6. Land Preparation and Field Layout

Proper land preparation ensures healthy root growth.

Steps:

1. Deep ploughing 1–2 times.
2. Remove weeds and crop residues.
3. Add well-decomposed FYM during last ploughing.
4. Prepare raised beds or ridges.

Recommended layout:

• Raised beds improve drainage.
• Irrigation channels every 3–4 meters.

7. Nursery Raising and Seed Rate

Marigold is usually transplanted through nursery seedlings.

Seed Rate

• African marigold: 400–600 g per hectare
• French marigold: 150–200 g per hectare

Nursery Preparation

• Prepare raised nursery beds (1 m width).
• Mix FYM and sand.
• Treat seeds with biofungicide (Trichoderma).

Steps:

• Sow seeds in rows 5 cm apart.
• Cover lightly with soil.
• Provide light irrigation.

Seed germination: 5–7 days
Seedling age for transplanting: 25–30 days

8. Transplanting Method and Spacing

Healthy seedlings ensure uniform crop stand.

Transplanting Tips

• Transplant during evening hours.
• Irrigate immediately after planting.
• Avoid root damage.

9. Nutrient Management

Balanced nutrition is essential for commercial marigold production.

Organic Manure

• FYM: 8–10 tons per acre

Recommended Fertilizer Dose (per acre)

Application Schedule

Full FYM + phosphorus + potash at planting.

Nitrogen in two splits:

• 30 days after transplanting
• 45 days after transplanting

10. Irrigation Management

Marigold requires moderate irrigation.

Irrigation Schedule

• Immediately after transplanting
• Every 5–7 days in summer
• Every 7–10 days in winter

Important:

Avoid waterlogging — it causes root rot.

Drip irrigation improves:

• Flower quality
• Water efficiency
• Fertigation management

11. Intercultural Operations

Weeding

• First weeding: 20 days after transplanting
• Second weeding: 40 days after transplanting

Pinching (Very Important)

Pinching means removing the terminal shoot.

Benefits:

• More branching
• Increased flower yield
• Uniform flowering

Timing: 30–35 days after transplanting.

Staking

Required for tall African varieties to prevent lodging.

Pruning

Remove dried flowers and diseased branches regularly.

12. Plant Growth Regulators (Optional)

Growth regulators improve flowering.

Use only under expert guidance.

13. Pest and Disease Management (IPM Approach)

Integrated Pest Management ensures sustainable marigold farming.

Major Pests

Aphids & Thrips

Symptoms: Leaf curling and sucking damage.

Management:

• Neem oil spray (5 ml/L)
• Yellow sticky traps
• Recommended insecticides if severe.

Caterpillars

• Hand picking
• Pheromone traps

Major Diseases

1. Damping Off

• Occurs in nursery stage.
• Avoid excess watering.
• Seed treatment with Trichoderma.

2. Leaf Spot

• Remove infected leaves.
• Spray suitable fungicides.

3. Powdery Mildew

• Improve air circulation.
• Sulfur-based sprays.

14. Flowering and Harvesting Stage

• Flowering begins 45–50 days after transplanting.
• Peak flowering: 60–90 days.

Harvesting Method

• Harvest fully opened flowers.
• Pick early morning or evening.
• Harvest every 2–3 days.

15. Yield Expectations

Yield varies depending on management practices.

16. Post-Harvest Handling and Storage
