• Can withstand heat but is sensitive to frost.
• Varieties available for year-round cultivation in different regions.
• Plays an important role in smallholder resilience against climate change.

Health Benefits

• Improves digestion due to its rich fiber content.
• Supports heart health by lowering cholesterol levels.
• Antioxidants present fight harmful free radicals in the body.
• Good for diabetic patients because of low glycemic index.
• Helps in weight management due to very low calorie count.
• Boosts brain function and reduces stress.
• Consuming regularly helps reduce the risk of obesity.

Key Features of Brinjal (Eggplant) Cultivation

Climate and Soil Requirements

• Requires warm and humid climate for best growth.
• Optimal temperature: 20°C to 30°C.
• Cannot tolerate frost conditions.
• Requires at least 6–8 hours of direct sunlight.
• Best suited soil: sandy loam or clay loam.
• Soil pH: 5.5 to 6.6 for ideal growth.
• Soil must be rich in organic matter for higher yield.
• Avoid waterlogged soils as roots are sensitive to standing water.

Land Preparation

• Land should be ploughed 2–3 times until fine tilth is achieved.
• Remove all weeds, stones, and debris for smooth planting.
• Prepare raised beds in low-lying areas to avoid root rot.
• Mix 20–25 tons of farmyard manure (FYM) or compost before final ploughing.
• Ensure proper leveling for uniform irrigation flow.
• Deep ploughing helps expose soil pests and larvae to sun.
• Line and peg system recommended for accurate spacing.
• Maintain soil moisture during preparation.

High-Yielding and Hybrid Seed Selection

• Choose seeds from reliable agricultural firms.
• Local, improved, and hybrid varieties are available.
• Select based on regional climate and market demand.
• Popular hybrids: Pusa Purple Long, Arka Navneet, Pusa Shyamala.
• Hybrids provide higher yield per acre.
• Selection depends on resistance to pests/diseases.
• Small, uniform, and certified seeds should be preferred.
• Availability of seeds from government-certified outlets recommended.

Seed Treatment

• Treat seeds with fungicides like Captan/Thiram (2–3 g per kg seed).
• Bio-fungicides like Trichoderma also protect against soil diseases.
• Soak seeds in warm water to improve germination.
• Use neem cake extract to reduce nematode infestation.
• Sometimes hot water treatment is used before sowing.
• Treated seeds show higher germination and healthy seedlings.
• Reduces chances of damping-off disease in nurseries.
• Encourages uniform sprouting and stronger early growth.

Sowing and Planting Methods

• Seeds first raised in nursery beds for 5–6 weeks.
• After healthy seedlings appear, transplant them into the field.
• Spacing: 60 x 45 cm for normal varieties, 75 x 60 cm for hybrids.
• Transplant seedlings during evening hours to reduce stress.
• Light irrigation immediately after transplanting.
• Square planting helps utilize land effectively.
• Ensure seedlings are free from pests before transplanting.
• Grown both in open fields and polyhouses.

Nutrient and Fertilizer Management

• Apply FYM at 20–25 tons/acre during land prep.
• Use recommended dose of NPK: 100:50:50 kg per acre.
• Top dressing of urea after 30 days and again after 60 days.
• Zinc and boron sprays boost brinjal flowering.
• Foliar spray of micro-nutrients enhances fruit quality.
• Organic fertilizers ensure long-term soil fertility.
• Avoid excessive nitrogen (causes excessive leaves, poor fruits).
• Balanced nutrition increases yield and uniform fruit size.

Irrigation and Water Management

• Brinjal (Eggplant) requires regular irrigation.
• First irrigation immediately after transplanting.
• Subsequent irrigation every 7–12 days depending on soil type.
• Drip irrigation is best for high efficiency and reduced water loss.
• Avoid water stagnation to prevent root diseases.
• Moisture is most critical at the flowering and fruiting stage.
• Mulching conserves soil moisture.
• Overwatering reduces yield and causes wilt.

Intercultural Operations

• Weeding should be done 2–3 times during early stages.
• Use a hand hoe or tractor cultivator for weeding.
• Earthing up provides plant support and prevents lodging.
• Mulching controls weeds and conserves soil moisture.
• Remove diseased or damaged plants early.
• Intercropping with onion, garlic, or coriander helps pest control.
• Thinning of excess plants for uniform spacing.
• Crop monitoring at least once a week is essential.

Pest Management

• Major pests: Fruit and shoot borer, aphids, jassids, whiteflies, mites.
• Use pheromone traps to control fruit borers.
• Neem oil sprays help reduce sucking pests.
• Avoid excessive pesticide use to prevent resistance.
• Pruning infested shoots improves crop health.
• Introduce natural enemies like ladybird beetles for aphid control.
• Maintain proper spacing to reduce pest spread.
• Use IPM (Integrated Pest Management) practices regularly.

Disease Management

• Common diseases: Bacterial wilt, damping-off, leaf spot, little leaf disease.
• Seed treatment prevents early-stage fungal diseases.
• Use resistant varieties whenever possible.
• Crop rotation reduces soil-borne infections.
• Roguing (removing infected plants) reduces spread.
• Spray fungicides as recommended for specific problems.
• Maintain field hygiene by removing plant debris.
• Proper drainage avoids fungal root diseases.

Harvesting and Post-Harvest Management

• Brinjal (Eggplant) fruits ready in 60–80 days (depending on variety).
• Harvest when fruits are glossy, firm, and tender.
• Mature but overripe fruits lose market value.
• Harvest at regular intervals to increase productivity.
• Handle fruits carefully to avoid bruising.
• Pack in bamboo baskets or crates with soft lining.
• Store at cool temperature (10–12°C) for longer shelf life.
• Transport carefully to markets for best prices.
