Favourable Climate

Climate
  • Brinjal is a warm season crop and requires a long warm growing season. 
  • It is very susceptible to frost.
Temperature
  • Requires day temperature below 35℃ and night temperature of above 16℃.
  • Temperature below 15℃ will affect the growth of the plant as well as fruit quality.
  • A temperature ranging from 13-21℃ is ideal for Brinjal.
  • Low humidity and high temperature can cause heavy flower drop and poor fruit set.
Crop Water Requirements
  • Water requirement – Equivalent to 600-1000 mm of rainfall.
  • It cannot withstand excessive rainfall especially during flowering and fruit set.
  • Excessive rainfall brings defoliation, wilting and rotting of the plant.

Favourable Soil

Type
  • Sandy loam soil and heavy clay soil with good water holding capacity.
  • Well drained and fertile soil is preferred for the crop.
pH
  • Required range – 6.5-7.5
  • If pH is < 6.5 add Lime
  • If pH is > 7.5 add Gypsum

Nursery Preparation

Nursery Preparation

Method- 1

  • For transplanting in 1 acre area, 0.1 acre (4 Guntha) nursery is required.
  • Prepare four beds of size 7.2 m length X 1.2 m width X 10cm height.
  • Sow the seeds in line at 5 cm apart and cover with soil.
  • Water the nursery beds daily twice till germination and once after germination.
  • Ten days before transplanting, reduce the quantity of water application to the nursery beds to harden the seedlings.
  • After 3 days of seed germination drench the seedbed with Ridomil @ 20 gms. in 10 lit of water, to protect the seedlings from damping-off disease.
  • Spray 19:19:19 @ 5 gm + Thiamethoxam @ 0.25 gm per lit water at 25 days after sowing.

Method- 2

  • Fill the pro trays with Cocopeat @ 1.2 kg Cocopeat per tray. 
  • Sow the treated seeds in pro trays @ 1 seed per cell.
  • Cover the seed with cocopeat and keep the trays one above the other and cover with a polythene sheet till germination starts (5 Days).
  • After 6 days, place the pro trays with germinated seeds individually on the raised beds inside a shade net.
Nursery Duration
  • 30-35 days
  • The seedlings are ready for transplanting when they attain a height of 15 cm with 2-3 true leaves.
Seed Rate
Varieties
160 gram seeds for transplanting 1 acre area
Hybrids
80 gram seeds for transplanting 1 acre area

Seed Treatment

   Treat the seeds with

  • Imidacloprid – 4 ml

Instructions – Mix the above quantity in two L of water for one kg of seeds. Dip the seeds in solution for 10 min & then shade dry for 15 min.

  • Carbendazim- 2 gram

Instructions – Above treated seeds are to be again treated with the Carbendazim 2 gram for 1 kg of seeds.

 

Land Preparation

Land Preparation
  1. Ploughing method – Plough the land 1 or 2 times based on soil type.
  2. Mix the following in field, and keep it in open air for 10 days for proper decomposition – 

                FYM – 2 tons

                Composting Bacteria – 3 kg

           3. Spread the above mixture over soil and run rotavator to the entire field making the soil as a fine tilth.

Bed Preparation
  1. Bed preparation- Prepare ridges and furrows 2 ft or 3 ft apart with the help of tractor.

Root Dip Treatment

  • Take 20 liter water in a flat container.
  • Mix 40 gm Carbendazim + 40 ml Imidacloprid. 
  • Dip the roots in solution for 5 minutes before transplanting.
  • For plants in pro trays – Dip the pro trays in container for 5 min. 

Transplanting

  • Transplant the seedlings on the ridges 60 cm apart. 
  • Press the soil firmly around the roots to eliminate air pocket.
  • It is advisable to transplant the seedlings preferably during the evening hours to protect from hot sun.

Nutrient Management

  • Total Requirement 100:50:30 N:P:K kg per acre. 
  • At sowing apply-

               Urea – 109 kg

               Single Super Phosphate – 308 kg

               Muriate of Potash – 50 kg

  • 30 Days after transplanting – 

                Urea- 54 kg 

  • 45 Days after transplanting – 

               Urea- 54 kg 

Irrigation
