General Nutrient Management

Fertilizer Application

• Nitrogen: 80-150 kg/hectare (varies by crop)
• Phosphorus: 40-60 kg/hectare
• Potassium: 60-80 kg/hectare
• Organic Matter: 10-15 tons FYM/hectare
• Micronutrients: Zinc, boron, iron if deficiency observed

Split Application

• Apply organic manure and P, K at field preparation
• Apply nitrogen in 2-3 splits during growing season
• Foliar spray micronutrients if deficiency signs appear
• Drip irrigation facilitates fertigation (fertilizer through irrigation)

Water Management

• Requirement: Most vegetables need 30-60 cm water annually
• Frequency: Light, frequent irrigation better than heavy, infrequent
• Critical Stages: Seedling, flowering, and fruit development
• Method: Drip irrigation ideal for vegetables; flood irrigation common
• Drainage: Ensure proper drainage to prevent root rot
• Summer: Irrigation every 3-5 days; winter every 7-10 days

Pest & Disease Management

Common Pests in Vegetables

• Aphids: Use neem oil or insecticidal soap
• Leaf Hoppers: Spray thiamethoxam or imidacloprid
• Whiteflies: Yellow sticky traps; spray insecticides
• Caterpillars: Use Bt formulations or carbaryl
• Spider Mites: Spray dicofol or hexythiazox

Common Diseases

• Damping Off: Use fungicide-treated seeds; avoid waterlogging
• Powdery Mildew: Apply sulfur or systemic fungicides
• Leaf Spots: Use copper fungicides; remove affected leaves
• Bacterial Wilt: Control insect vectors; use resistant varieties
• Root Rots: Ensure proper drainage; use resistant varieties

Harvesting & Post-Harvest

Harvesting Guidelines

Fresh vegetables at harvest time ready for market

• Tomato: Pick when fully colored but slightly firm
• Cucumber: Pick when 15-20 cm long and tender
• Leafy Vegetables: Pick outer leaves continuously; harvest before bolting
• Beans/Peas: Pick green pods when tender; harvest regularly
• Onion: Harvest when tops dry; cure for storage

Storage

• Refrigeration: Most vegetables store better in cold storage
• Temperature: 5-10°C for most vegetables
• Humidity: 85-95% humidity required
• Duration: Varies by crop (2-3 weeks to several months)
• Avoid Mixed Storage: Some crops release ethylene affecting others

Profitability & Economics

• Vegetables offer 3-4 times higher returns than cereal crops
• Short duration allows 2-3 crops per year in many cases
• High market demand ensures good price realization
• Suitable for small and marginal farmers
• Create employment opportunities in production and marketing
• Export potential for quality vegetables
