Brinjal — Package of Practices
A hardy, long-season relative of tomato that keeps bearing for months when it is fed steadily, mulched, and protected early from shoot-and-fruit borer.
Overview
Brinjal (eggplant) is a warm-season Solanaceae crop grown for its glossy fruits, which range from long and slender to oval or round depending on the type. It adapts to many soils, crops over a long period with repeated pickings, and responds strongly to drip fertigation and plastic mulch.
Its biggest challenge is the shoot-and-fruit borer, so an IPM-first routine — clean fields, traps and prompt removal of bored shoots — matters more than any single spray.
Climate & season
Brinjal likes warm, bright weather around 25–32 °C and tolerates heat better than tomato, but it is frost-sensitive and very long, hot, dry spells cause flower drop.
- Time the crop so the long fruiting period avoids frost and peak heat.
- Steady warm weather gives continuous flowering and fruiting.
- Hot dry winds at flowering shed flowers — keep soil moisture even.
Soil & land preparation
Well-drained, fertile sandy loam to clay loam is ideal, with a pH of 5.5–6.6. Avoid waterlogging, which invites wilt.
- Plough to a fine tilth and remove residues and weeds.
- Incorporate 25 t/ha of farmyard manure before the last ploughing.
- Mix in Azospirillum and Phosphobacteria (2 kg/ha each) with 50 kg of manure.
- For drip, form raised beds and lay black LDPE mulch (25 micron); bury the edges.
- Rotate 2–3 years away from other Solanaceae (tomato, chilli, potato).
Choosing a type & seed
Pick a type by your market and conditions — long, oval or round fruit; purple, green or white — and prefer types with tolerance to the problems common in your area (bacterial wilt, little leaf, heavy borer pressure). Hybrids give higher, more uniform yields; open-pollinated types let you keep seed. No specific cultivar is named here.
Seed rate
- Hybrid: 150–200 g/ha
- Open-pollinated: 300–400 g/ha
- Raise seedlings in pro-trays for clean, uniform plants.
Seed treatment
- Treat seed with Trichoderma viride 4 g/kg or Thiram 3 g/kg against damping-off.
- Then treat with Azospirillum before sowing.
Nursery, transplanting & spacing
- Raise a healthy nursery in pro-trays or on raised beds; keep moist and lightly shaded.
- Harden seedlings for 4–5 days before lifting.
- Transplant at 25–30 days (4–5 true leaves) in the evening and water in.
- Spacing: rows 60 cm apart, plants 35–40 cm within the row.
- Gap-fill missing plants about 7 days after transplanting.
Nutrient management
The figures below follow a standard recommendation for brinjal (F1 hybrid), rewritten as plain steps. The dose is N–P–K 200 : 150 : 100 kg/ha, delivered through drip fertigation. Fine-tune to your soil test and local advisory.
Apply as basal (before planting)
- Farmyard manure 25 t/ha, worked in before the last ploughing.
- Azospirillum 2 kg/ha + Phosphobacteria 2 kg/ha, mixed with about 50 kg of manure.
- 75% of the phosphorus as single superphosphate (≈ 703 kg/ha) — phosphorus is given mostly basal.
Give through the drip (fertigation)
Deliver the rest with water-soluble fertilizers, split once every three days through the crop, building up through flowering and the long fruiting period. Inject fertilizer mid-irrigation and flush the lines afterwards. Over the season the water-soluble fertilizer need works out to roughly:
| Fertilizer | Approx. season total |
|---|---|
| 19:19:19 | 79 kg/ha |
| 12:61:0 (MAP) | 37 kg/ha |
| 13:0:45 (potassium nitrate) | 189 kg/ha |
| Urea | 340 kg/ha |
Irrigation
- Irrigate immediately after transplanting to settle the seedlings.
- Furrow: about every 7 days; drip: short, light irrigation often (also carries the fertigation).
- Flowering and fruiting are the critical stages — never let the crop dry out then.
- Avoid waterlogging, which triggers wilt and root rot.
Weeds & special care
- Keep the crop weed-free for the first 30–45 days.
- Weed and earth-up around 30 and 60 days after transplanting.
- Mulch (plastic or organic) suppresses weeds and keeps moisture even.
- A pre-emergence herbicide (e.g. pendimethalin/fluchloralin) is an option — follow the label.
Plant protection
Work the IPM way — healthy plants, clean fields, traps and weekly scouting, with a chemical only when a pest crosses the level that causes real loss. The shoot-and-fruit borer is the key target.
Major pests
| Pest | Damage | Manage with |
|---|---|---|
| Shoot & fruit borer (Leucinodes) | Bores into shoots (they droop) then into fruit, filling it with frass | Clip and destroy bored shoots/fruit weekly, pheromone traps, release Trichogramma, neem; need-based chlorantraniliprole / spinosad use sparingly |
| Whitefly & jassids | Suck sap, cause leaf curl/yellowing, spread viruses | Yellow sticky traps, neem oil, remove badly infected plants |
| Epilachna beetle (hadda) | Adults and grubs skeletonise leaves | Hand-pick beetles and egg masses, neem; spot-spray only if severe |
| Mites | Bronzing and curling in hot, dry weather | Keep moisture even, spray wettable sulphur or a recommended miticide |
| Root-knot nematode | Galled roots, stunting, wilting | Neem cake in the pit, resistant rootstock, rotation |
Major diseases
| Disease | Signs | Manage with |
|---|---|---|
| Damping-off | Seedlings rot and topple in the nursery | Treated seed, raised beds, Trichoderma, avoid overwatering |
| Little leaf (phytoplasma) | Tiny, bunched leaves and no fruit; spread by leafhoppers | Rogue out infected plants early, control leafhoppers |
| Bacterial wilt | Sudden wilting with green leaves; ooze from a cut stem | Resistant types, rotation, raised beds, good drainage |
| Phomopsis blight & fruit rot | Leaf/stem spots and soft, rotting fruit | Clean seed, remove rotten fruit, protectant fungicide as needed |
| Fusarium / Verticillium wilt | Yellowing and wilting, often one side first | Resistant types, rotation, Trichoderma, soil health |
Use chemicals safely
The products above are examples, not a prescription. Doses, approved crops and pre-harvest intervals differ by country and change over time. Always read the label, wear protective gear, use the correct dose, observe the waiting period before harvest, protect bees, and confirm with your local agriculture officer.
Harvest & yield
- First picking comes about 55–60 days after transplanting.
- Pick tender, glossy fruit every 4–5 days, before the skin dulls and seeds harden.
- Cut (don't pull) the fruit with a short stalk; handle gently.
- Typical yield: 40–60 t/ha, and more from good hybrids under drip.
Post-harvest handling
- Brinjal bruises easily — handle and pack with care.
- Grade by size, colour and soundness; discard cracked or dull fruit.
- Pack in ventilated crates, not overfilled.
- Store around 10–12 °C with high humidity; colder causes pitting.
Field tips that pay off
- Clip borer-hit shoots the moment they droop — it breaks the pest cycle cheaply.
- Drip + plastic mulch gives even moisture, fewer weeds and cleaner fruit.
- Pheromone traps and weekly scouting beat calendar spraying.
- Don't over-fertilise nitrogen — lush plants set less fruit and pull in more pests.
