Step-by-Step Garlic Cultivation Guide
Planting Time
The ideal time for planting garlic is during the cool season, typically mid-October to early November. Planting during these months ensures that garlic establishes itself during cooler periods, reducing stress and enhancing growth.
Seed Rate
Approximately 2-3 kg of garlic cloves are required per 100 square meters, depending on the variety.
Planting Method
- Prepare the Bed:
- Create well-drained beds with raised furrows.
- Ensure the soil is rich in organic matter.
- Planting Cloves:
- Plant cloves 3-4 inches apart in rows spaced 4 inches apart.
- Plant cloves 1 inch deep with the pointed end facing upward.
- Cover with soil and ensure proper moisture.
- Post-Planting Care:
- Mulch with dry straw or grass to retain soil moisture and suppress weeds.
- Avoid waterlogging by ensuring proper drainage.
Fertilizer Management
Garlic requires a balanced supply of nutrients for optimal growth.
Fertilizer Schedule
| Fertilizer | Quantity per 100 kg Soil |
|---|---|
| Compost | 20 kg |
| Urea | 800 g |
| Triple Super Phosphate (TSP) | 1 kg |
| Potash | 1.5 kg |
| Gypsum | 400 g |
Application Steps:
- Initial Application:
- Mix compost, TSP, gypsum, and half the urea and potash into the soil during land preparation.
- Post-Transplanting:
- Apply the remaining urea and potash in two equal splits at 25 and 50 days after planting.
Irrigation
Proper irrigation is vital for garlic growth but must be managed to prevent waterlogging.
- Initial Watering: Light irrigation 3-4 days after transplanting.
- Regular Irrigation: Provide consistent moisture, especially after fertilization applications.
- Drainage: Ensure proper drainage using side canals to prevent waterlogging.
- Post-Irrigation Care: Break the soil crust to facilitate air circulation.
Weed Management
Effective weed control is crucial to reduce competition for nutrients and water.
- Thorough Weeding: Perform multiple weed removal sessions within 25-30 days of harvesting.
- Clean Practices: Use clean agricultural tools and disease-free seeds to minimize weed growth.
- Mulching: Apply organic mulch to suppress weed growth and retain soil moisture.

- Control Methods:
- Insecticides: Use imidacloprid-based insecticides.
- Natural Predators: Introduce beneficial insects like ladybugs.
2. Leaf Miners
- Description: Pests that create tunnels in leaves, reducing photosynthesis.
- Control Methods:
- Insecticides: Use emamectin benzoate or cypermethrin-based insecticides.
- Crop Rotation: Rotate crops to disrupt pest life cycles.
3. Mites
- Description: Microscopic pests that cause stippling and discoloration on leaves.
- Control Methods:
- Sulfur-Based Sprays: Effective against mites.
- Regular Monitoring: Inspect plants frequently to catch infestations early.
Common Diseases

- Fungicides: Use mancozeb + metalaxyl-based fungicides.
- Proper Spacing: Ensure good air circulation to reduce humidity.
2. Purple Blotch
- Cause: Fungal disease.
- Symptoms: Purple spots on leaves.
- Control Methods:
- Fungicides: Apply carbendazim or mancozeb-based fungicides.
- Sanitation: Remove and destroy infected plant parts.
3. Basal Rot
- Cause: Soil-borne disease.
