  • Brinjal (Solanum melongena) is a widely grown vegetable in India.
  • It is cultivated for its edible fruit, rich in vitamins and minerals.
  • Suitable for both small-scale and commercial farming.
Climate and Soil Requirements
  • Grows best in warm, humid climates (21–30°C).
  • Requires well-drained, fertile loamy soils with pH 6.0–7.0.
  • Cannot tolerate frost or waterlogging.
Recommended Varieties
  • Pusa Purple Long, Pusa Purple Cluster, Arka Keshav, Arka Nidhi, Punjab Bahar, and Bhagyamati are popular varieties.
  • Hybrid varieties offer higher yield and disease resistance.
Seed Rate and Sowing
  • Seed rate: 400–500 g/ha for open-pollinated, 200–250 g/ha for hybrids.
  • Sow seeds in raised nursery beds; transplant 4–6 week-old seedlings.
  • Spacing: 60 x 45 cm (varietal), 75 x 60 cm (hybrid).
Field Preparation and Transplanting
  • Plough field thoroughly and incorporate organic manure (20–25 t/ha FYM).
  • Apply basal dose of fertilizers before transplanting.
  • Transplant healthy seedlings with adequate root ball.
Nutrient Management
  • Recommended dose: 100–120 kg N, 60–80 kg P2O5, 50–60 kg K2O per hectare.
  • Apply half N and full P, K as basal; remaining N in two splits after transplanting.
  • Micronutrients (Zn, B) may be supplemented if deficient.
Irrigation Management
  • Requires regular irrigation, especially during flowering and fruiting.
  • Frequency: 7–10 days in winter, 4–5 days in summer.
  • Avoid waterlogging to prevent root diseases.
Weed and Intercultural Management
  • Keep field weed-free for first 30–40 days after transplanting.
  • Hand weeding or hoeing recommended at 20 and 40 days after transplanting.
  • Mulching helps conserve moisture and suppress weeds.
Major Pests and Their Management
  • Fruit and shoot borer: Remove infested shoots/fruits; spray insecticides (e.g., Emamectin benzoate 0.002%).
  • Jassids, aphids, whiteflies: Use neem-based products or recommended insecticides.
  • Practice crop rotation and use resistant varieties.
Major Diseases and Their Management
  • Bacterial wilt: Use resistant varieties; avoid waterlogging.
  • Phomopsis blight: Remove infected plants; spray fungicides (e.g., Mancozeb 0.25%).
  • Alternaria leaf spot: Apply appropriate fungicides and maintain field hygiene.
Harvesting and Yield
  • Harvest fruits when they are glossy and tender, before seeds harden.
  • Harvesting starts 60–80 days after transplanting, continues for 2–3 months.
  • Average yield: 25–35 t/ha (varieties), 40–50 t/ha (hybrids).
Summary of Package of Practices
  • Select suitable variety and prepare nursery.
  • Follow recommended nutrient and irrigation schedule.
  • Implement integrated pest and disease management.
  • Harvest at proper stage for best quality and yield.
