i. Quality Seedling Production

Protected nursery

The nursery area is covered with 50 per cent shade net

The raised beds of 1 m width and convenient length are formed

The seedlings are raised in portrays

The sterilized cocopeat is used for raising seedlings @ 300 kg /ha is mixed with 5 kg of neem cake along with Azospirillum and Phosphobacteria each @ 1 kg.


About 200 g of brinjal seeds is required to produce seedlings for 1 ha.

The seeds are mixed with Azospirillum @ 200 g/kg and are shade dried for half an hour.

After 6 days, the germinated portrays are individually placed on the raised beds inside the shade net.

Watering is done by rose can everyday (twice/day) up to seed germination.

Panchakavya spray @ 3% (30 ml/l) is done at 15th day of sowing.

19:19:19 + MN @ 0.5% (5g/l) solution is drenched at 18 days after sowing.

The brinjal seedlings of 35 days old are ready for transplanting.

ii. Planting

The main field is ploughed 4 times. Chisel and disc plough each one time and cultivator twice.

FYM @ 25 t /ha is applied before the last ploughing.

75 % of the total recommended dose of super phosphate i.e. 703.13 kg/ha is applied as basal dose.

Azospirillum and Phosphobacteria each @ 2 kg / ha along with FYM 50 kg and Neem cake @100 kg is applied before last ploughing.

Pseudomonas fluorescens or Trichoderma viridi @ 2.5 kg/ha along with 100 kg of FYM is applied before last ploughing.

Raised beds of 120 cm width (4 feet) are formed at an interval of 30 cm (1 feet)and the laterals are placed at the center of each bed.

Before planting, the beds are watered using drip system for 8 to 12 hours.

Pre-emergence weedicide spray of pendimethalin (Stomp) is applied @ 3 lit/ ha(1 kg a.i./ha) just before transplanting.

35 days old seedlings are dipped in 0.5% solution of Pseudomonas fluorescens for30 minutes and are transplanted at a spacing of 90 x 60 x 75 cm in the paired row system in the main field.

One row of African marigold seedlings of 40 days old are planted simultaneously for every 16 row of brinjal seedlings.

Gap filling is done at 7th day after transplanting.

iii. Fertigation techniques

For brinjal F1 hybrid, a dose of 200: 150: 100 kg of NPK/ ha is applied throughout the cropping period through split application. The split dose is applied once in every three days through fertigation.

iv. Intercultivation

Foliar spraying with Pseudomonas fluorescens 0.5 % at 15 days interval for 6 times.

Triacontanol 625 ml is mixed with 500 l of water (1.25 ppm), is sprayed on 15th and 30th days after planting.

Planofix @ 125 ml in 500 l of water (0.25ppm) is sprayed at 45, 60 and 90th DAP.

Micronutrient mixture @ 1 g/lit (0.1%) is sprayed for 2 times at 40th and 80th days after planting.

19:19:19: + MN @ 1 % (10 g/lit) is sprayed at 60 days after planting.

v. Harvesting and Post Harvest management

Harvesting of brinjal fruits is carried out at fully matured stage.

The fruits are graded based on the size. The damaged and pest affected fruits are sorted out and then packed in the crates for market.
