Brinjal Grafting Technology

Well drained soil rich in organic matter with pH of 6.5-7.5.
December – January and May – June

Thirty days old brinjal seedlings of desirable variety/hybrid are used as scion and grafted on fifty five to sixty days old Solanum torvum seedlings by cleft grafting method.
Rootstock – Non bitter Solanum torvum
Scion          – COBH 2
Method of grafting – Cleft grafting

The grafted plants are to be placed in the mist chamber for 15 days and in the shade net for 15 days for hardening.

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
The established grafts are to be planted in the main field at a spacing of 1.0 x 1.0 m.

10000 grafts are required for one ha.

The recommended fertilizer dose of NPK @ 125:175:125 kg/ha has to be applied as basal and125 kg N/ha as top dressing on 30th day of planting.
Mulch with black LDPE sheets of 25 micron thickness and bury both the ends into the soil to a depth of 10 cm
Apply Pendimethalin 1.0 kg a.i. / ha or Fluchloralin 1.0 kg a.i / ha as pre-emergence herbicide, followed by hand weeding once at 30 days after planting.
After establishment of seedlings, irrigate at weekly intervals
Spray 2 ppm (1 ml in 500 lit) Triacontanol plus Sodium Borate or Borax 35 mg/l of water 15 days after transplanting and at the time of full bloom to increase the yield.
Hand weeding, top dressing and earthing up on 30th day of planting.
First ratoon crop can be retained for four months. The fertilizer dose of 100:150:200 kg NPK / ha has to be applied for ratoon crop. In the same manner second ratoon crop can also be raised. The crop can be retained for 6 months and after that ratooned by cutting back of main branches to 20 cm height from the base.
The yield for hybrids in the main crop will be 70 t/ ha. First ratoon crop will be 45 t/ha and second ratoon crop will be 40 tonnes/ ha by adopting this technology.
