Brinjal

Season

Soil

Well drained soil rich in organic matter with pH of 6.5-7.5.

Season of Sowing

December – January and May – June.

Field preparation

Plough the land to fine tilth. Thoroughly prepare the field with the addition of FYM @ 25 t/ ha and form ridges and furrows at a spacing of 60 cm. Apply 2 kg/ha of Azospirillum and 2 kg/ha of Phosphobacteria by mixing with 50 kg of FYM. Irrigate the furrows and transplant 25 days old seedlings on the sides of ridges. Life irrigation to be given on 3rd day of planting.

Nursery bed preparation

Apply FYM 10 kg, neem cake 1 kg, VAM 50 g, enriched super phosphate 100 g and furadon 10 g per square metre before sowing. Area required for raising seedling for planting 1.0 ha is 100 sq.m.

Irrigation

Irrigation

After establishment of seedlings, irrigate at weekly intervals.

Layout and planting for drip irrigation and fertigation

Apply FYM @ 25 t / ha as basal dose before last ploughing.
Apply 2 kg/ha of Azospirillum and 2 kg/ha Phosphobacteria by mixing with 50 kg of FYM.
Apply 75 % total recommended dose of superphosphate i.e. 703 kg / ha as basal.
Install the drip irrigation with main and sub main pipes and place lateral tubes at an interval of 1.5 m.
Place the drippers in lateral tubes at an interval of 60 cm and 50 cm spacing with 4 LPH and 3.5 LPH capacities respectively.
Form raised beds of 120 cm width at an interval of 30 cm and place the laterals at the centre of the each bed.
Before planting, wet the beds using drip system for 8-12 hrs.
Planting to be done at a spacing of 90x60x75 cm in the paired row system, using ropes marked at 75 cm spacing.
Spray Pendimethalin 1.0 kg a.i./ha or Fluchloralin 1.0 kg a.i/ha as pre-emergence herbicide at 3rd day after planting.
Gap filling to be done at 7th day after transplanting.

Protected cultivation

Protected nursery

Prepare the nursery area of 3 cents with slanting slope of 2 % for the seedling production to cover 1 ha.
Cover the nursery area with 50 % shade net and cover the sides using 40 / 50 mesh insect proof nylon net.
Form raised beds of 1 m width and convenient length and place HDPV pipes at 2m interval for further protection with polythene sheets during rainy months.
Mix sterilized cocopeat @ 300 kg with neem cake 5 kg along with Azospirillum and phosphobacteria each @ 1 kg. Approximately 1.2 kg of cocopeat is required for filling one protray. 200 protrays are required for the production of 18,700 seedlings, which is required for one hectare adopting a spacing of 90 x 60 x 75 cm in paired row system.
Sow the treated seeds in protrays @ 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.
After 6 days, place the protrays with germinated seeds individually on the raised beds inside the shade net.
Water with rose-can everyday and drench with 19:19:19 @ 0.5% (5g/l) at 18 days after sowing.
