INTRODUCTION
The recommended biofertilizer for grapes are
Azotobacter in combination with PSB.
Mycorrhizal inoculation gives additional benefit
for mobilizing nutrients.
Biofertilizers are applied as set treatment
method as well as soil application in standing
crop.

SET TREATMENT
This method is recommended for treating the sets
of sugarcane, cut pieces of potato, banana
suckers, hard wood cuttings of grape vines. Grape
vines are used for biofertilizer treatment using
hardwood cuttings. Healthy pencil-thick stems
bearing few buds and the ripened vine should be
selected for propagation and biofertilizer
application.

SET TREATMENT
Prepare culture suspension by mixing 1 kg each of
nitrogen and phosphatic biofertilizer packets in
40 - 50 litres of water. Immerse the hard wood
cuttings of grape vine planting material required
for one acre in the suspension for 30
minutes. Bring and dry them in shade for some
time before planting. Irrigate the field within
24 hours. For set treatment, the ratio of
biofertilizer to water is approximately 150.

SOIL APPLICATION METHOD
Mix 2 3 kg each of the Azotobacter and PSB
culture packets with 100 kg of well decomposed
cattle manure/ compost for one acre of land and
Sprinkle water to the mixer. Keep the mixer
overnight for curing. Broadcast into soil at the
time of planting or at the time of irrigation
For long duration crop 20-30 packets of
biofertilizer (200g) are mixed with 80-120 kg
Cattle manure or soil for one acre land.

Mycorrhizal Application in Grape

• Apply mycorrhizal culture in the grape nursery _at_
  100 gm per sq.m. three centimeter below the soil.
• For out planting, apply 20 gm mycorrhizal culture
  per seedling into the planting pit and cover
  with soil.
• For existing plant, apply mycorrhizal culture _at_
  200 gm near the root zone along with other
  fertilizers.
