This guide will cover all you need to know about growing brinjal. It will address climate, soil, pest control, and harvesting. Whether you’re a home gardener or a commercial farmer, ThinkFood is here to help you cultivate healthy and productive brinjal plants!
Climate Conditions for Growing Brinjal
Brinjal thrives in warm weather, requiring a long growing season. Ideal temperatures range from 13°C to 21°C; growth can stall if temperatures drop below 17°C. In India, brinjal is typically grown during the rainy and summer seasons, though it can be cultivated year-round in regions with milder winters.
Ideal Planting Seasons
- Rainy season: June to July
- Winter season: October to November
- Summer season: February to March
Brinjal can adapt to elevations up to 1,200 meters above sea level, making it suitable for diverse climates.
Soil Requirements for Brinjal Cultivation
Brinjal is a hardy crop that grows well in various soil types, but it prefers well-drained, fertile soil. Sandy soils often yield fruits earlier, while clayey soils can result in higher overall yields. The ideal soil pH for brinjal is between 5.5 and 6.6. Before planting, enrich the soil with organic matter, such as well-decomposed farmyard manure (FYM).

Seed Rate and Treatment
For planting one hectare of brinjal, you will need approximately 370–500 grams of seeds. To protect against fungal infections, treat seeds with Trichoderma viride or a Carboxyn + Thiram mixture.
Seed Treatment Steps
- Treat seeds with Trichoderma viride at 2g per 100g of seeds.
- Alternatively, use a mixture of Carboxyn 37.5% + Thiram 37.5% to protect against soil-borne diseases.
Nursery Preparation for Brinjal
Brinjal seeds are typically sown in a nursery before being transplanted into the field. To prevent waterlogging, create raised beds that are 10-15 cm high.
Key Tips for Nursery
- Use well-decomposed FYM in the beds.
- Sow seeds in thin rows, spaced 5-7 cm apart, and cover lightly with soil.
- Water gently until germination, and cover beds with dry straw or leaves to maintain moisture.
Seedlings are ready for transplanting after 4-6 weeks, reaching about 15 cm in height and developing 2-3 true leaves.
Field Planting and Spacing
Once seedlings are ready, it’s time for transplanting. Proper field preparation involves multiple plowings to achieve a fine tilth.
Spacing Guidelines
- Long-fruited varieties: 60 x 45 cm
- Round varieties: 75 x 60 cm
- High-yielding varieties: 90 x 90 cm
Transplanting Tips
- Transplant in the evening for better results.
- Dip roots in a Bavistin solution before transplanting.
- Water the field a few days before transplanting to ensure moisture.
Fertilizer and Manure Application
Brinjal is a nutrient-demanding crop. For high yields, it is crucial to apply well-decomposed FYM (15-20 tonnes per hectare) along with fertilizers.
Fertilizer Schedule
- Apply half of the Nitrogen (N) and all of the Phosphorous (P2O5) and Potassium (K2O) at planting.
- Divide the remaining Nitrogen into three equal parts and apply it 1.5, 2.5, and 3.5 months after transplanting.
Irrigation and Water Management
Brinjal requires consistent moisture, particularly around the root zone.
Irrigation Schedule
- In winter: every 8-10 days.
- In summer: every 5-6 days.
Avoid waterlogging, as it can lead to root diseases.
Weed Control and Intercultural Operations
Weeds can hinder brinjal growth by competing for nutrients. Keeping the field weed-free, especially early on, is essential.
Weed Control Tips
- Use shallow cultivation to avoid damaging roots.
- Hoeing and earthing up can assist in weed control.
- Fluchloralin at 1.5 kg/ha is effective as a pre-emergence herbicide.
Pest and Disease Management
Brinjal is susceptible to pests like fruit and shoot borers, jassids, mites, and diseases such as bacterial wilt and Phomopsis blight.
Integrated Pest Management (IPM) Practices
- Set up bird perches to attract predatory birds.
- Use pheromone traps for monitoring pests.
- Spray neem oil (2%) or NSKE (5%) to control sucking pests.
- Rotate crops to prevent pest and disease build-up.
Harvesting and Yield
Brinjal fruits are typically ready for harvest about 120-130 days after sowing, depending on the variety.
Harvesting Tips
- Harvest every 8-10 days for continuous yield.
- Always leave part of the calyx on the fruit during harvest.
Under optimal conditions, farmers can expect yields of 25–30 tonnes per hectare for regular varieties, with hybrids producing even more.
Conclusion
Growing brinjal is a rewarding endeavor for both home gardeners and commercial farmers. Follow best practices for soil prep, planting, fertilizing, and pest control. This will ensure a healthy, abundant harvest. Whether in the plains of India or at higher elevations, with the right techniques, you will enjoy the fruits of your labour!
