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.
