🌾 Wheat Cultivation Guide
Overview
Wheat is a cool-season cereal crop and one of the world's most important staple foods. It's grown in the Rabi (winter) season in tropical regions and provides essential nutrition through high protein and carbohydrate content. Wheat is less water-demanding compared to rice.

Climate & Season Requirements
Ideal Season
- Season: Rabi (Winter) crop
- Sowing Time: October-November
- Harvesting Time: March-April
- Duration: 120-140 days depending on variety and location
Climate Requirements
- Temperature: 10-25°C optimal, with winter cooling beneficial
- Minimum Temperature: 0°C at germination
- Rainfall: 40-100 cm annually
- Humidity: Moderate humidity (50-70%)
- Sunlight: Requires good sunlight 6-8 hours daily
Water Requirements
- Total water requirement: 400-600 mm
- Critical stages: Tiller initiation and grain-filling
- Relies on winter rainfall; supplementary irrigation often needed
Soil Requirements
Soil Type
- Suitable: Loamy, clay loam, and well-drained soils
- pH Level: 6.0-7.5 (neutral to slightly alkaline)
- Fertility: Moderate to good fertility
- Drainage: Good drainage essential (intolerant to waterlogging)
Soil Preparation
- Plow field 2-3 times to achieve good tilth
- Break soil clods for uniform germination
- Add organic manure 3-5 tons per hectare
- Create slight raised beds to prevent waterlogging
- Conduct soil test for nutrient deficiency
Seed Selection & Sowing
Seed Rate
- Seed rate: 100-125 kg/hectare
- Use certified variety seeds with germination >90%
- Treat seeds with fungicide for disease protection
Sowing Method
Young wheat plants at early growth stage
- Method: Broadcast or line sowing
- Row Spacing: 22-25 cm apart for better management
- Depth: Sow 4-5 cm deep
- Seed Treatment: Use fungicides like trichoderma
Nutrient Management
Fertilizer Recommendations
| Nutrient | Recommended Dosage (kg/hectare) | Application Method |
|---|---|---|
| Nitrogen (N) | 80-120 | Split: 50% at sowing, 50% at tillering |
| Phosphorus (P) | 40-60 | Apply entire dose at sowing |
| Potassium (K) | 30-40 | Apply at sowing in K-deficient soils |
| Sulfur | 15-20 | If soil test indicates deficiency |
Micronutrients
- Zinc is critical for wheat productivity
- Apply zinc sulfate at 25 kg/hectare if deficiency observed
- Boron deficiency may require foliar spray
Water Management
- Pre-sowing: Field should have adequate moisture
- Post-sowing: Light irrigation if moisture is low
- 1st Irrigation: At 20-25 days after sowing (CRI - Crown Root Initiation)
- 2nd Irrigation: At 40-45 days (Tillering stage)
- 3rd Irrigation: At 60-70 days (Boot stage)
- 4th Irrigation: At 80-90 days (Milk stage)
- Total Irrigations: 3-4 depending on rainfall and soil
Weed Management
- Pre-emergence: Use pendimethalin at 1 kg a.i./hectare
- Post-emergence: 2,4-D sodium salt for broadleaf weeds at 25-30 days
- Manual Weeding: Hand weeding at 45-60 days
- Mechanical Weeding: Use hoeing tools for mechanical control
- Mulching: Organic mulch suppresses weeds
Pest & Disease Management
Major Pests
- Armyworm: Control with quinalphos or cypermethrin
- Sawfly: Monitor and treat at early infestation stages
- Termites: Treat soil with appropriate insecticides
Common Diseases
- Rust: Apply propiconazole or hexaconazole; use resistant varieties
- Powdery Mildew: Apply sulfur or systemic fungicides
- Leaf Spot: Use fungicides and maintain field sanitation
- Karnal Bunt: Use clean seed and manage crop rotation
See our Pesticides Guide for detailed recommendations.
Harvesting & Storage
Harvesting Time
Mature golden wheat field ready for harvesting
- Harvest when grain moisture is 12-15%
- Grain should be hard and golden yellow in color
- Complete harvesting before monsoon rains
- Use combine harvester or manual harvesting
Yield
- Average yield: 30-40 quintals/hectare
- High-yielding varieties: 40-50 quintals/hectare
- Yield depends on variety, management, and weather
Post-Harvest
- Dry grains to 12% moisture for storage
- Clean and remove impurities
- Store in aerated structures with temperature control
- Use hermetic storage for long-term preservation
Popular Wheat Varieties
- High-yielding Varieties (HYV): HD 2967, PBW 343, WH 1105
- Bread Wheat: Good for flour production
- Durum Wheat: For pasta production
- Disease-resistant Varieties: To combat rust and other diseases
💡 Key Success Tips:
- Sow at optimal time (October-November)
- Use certified quality seeds
- Practice crop rotation with legumes
- Apply irrigation at critical stages
- Monitor and manage pests and diseases
- Harvest at proper grain moisture
- Store with proper moisture and pest control
