Rapeseed Production Technology

Rapeseed (Brassica napus), also known as Canola, is a high-value oilseed crop rich in healthy fats and proteins. With advanced farming techniques and scientific management, farmers can achieve higher yields, better oil quality, and increased profitability while improving soil fertility.

 Key Steps for Profitable Rapeseed Cultivation

Ideal Climate & Soil Conditions

Temperature: 15-25°C – Thrives in cool and moist conditions

 Soil Type: Well-drained loamy or sandy loam soil (pH 5.5-7.0)

Water Requirement: Moderate irrigation, critical at flowering & pod formation

High-Yielding Rapeseed Varieties

Popular varieties: GSC 6, Pusa Bold, NRCDR 2, RH 749, Kranti

Disease-resistant types: Canola-quality varieties with low erucic acid & glucosinolates

Early-maturing varieties: Suitable for intercropping & short-season cultivation

Smart Sowing & Seed Treatment

Seed rate: 4-6 kg/ha for line sowing, 8-10 kg/ha for broadcasting

Best sowing time: Mid-September to early November (Rabi season)

Seed treatment: Treat with Azotobacter & PSB (Phosphate Solubilizing Bacteria) for enhanced nutrient uptake

Nutrient & Water Management

Balanced fertilization:

• Nitrogen (N): 60-80 kg/ha
• Phosphorus (P): 40-50 kg/ha
• Potassium (K): 25-30 kg/ha

Irrigation schedule: Essential at pre-flowering, flowering, and pod-filling stages

 Weed, Pest & Disease Control

Weed management: Use Pendimethalin (pre-emergence herbicide) for effective weed control

Common pests: Mustard aphids, flea beetles, sawflies – Managed using Neem-based biopesticides & IPM practices

Disease control: White rust, Alternaria blight – Prevent with crop rotation & fungicide applications

Harvesting & Post-Harvest Management

Harvest when pods turn golden yellow & moisture content drops below 10%

Proper drying ensures higher oil content & better market value

Average yield: 1.5-2.5 tons per hectare
