Nursery Raising
 Seed Rate: 8 – 10 Kg/Ha
 Proper nursery management and transplanting are
important operations in the onion crop.
 About 0.05 hectare nursery bed area is enough for getting
seedlings to transplant in one hectare.
 Field should be ploughed 5-6 times to break clods and well
pulverized to hold water.
 The debris of previous crops, weeds and stones should be
removed before bed preparation.
Main Field Preparation
 Prior to transplanting, field should be ploughed & disked properly
to eliminate debris and soil clods.
 Organic manures equivalent to 75 kg nitrogen/ha should be
incorporated at the time of last ploughing and beds with
appropriate size should be prepared after levelling.
 Water logging favours Anthracnose which is a devastating
disease thus flat bed should be avoided.
 Broad bed furrow (BBF) is best method for onion production as
excess water can be drained out through the furrow.
 BBF of 15 cm height and 120 cm top width with 45 cm furrow are
best to achieve proper spacing and population density. It is
suitable for drip and sprinkler irrigation as well.
Transplanting
 Proper care should be taken while selecting seedlings for transplanting.
 Over and under aged seedlings should be avoided for better establishment.
 At the time of transplanting, one third of the seedling top should be cut to
get good establishment.
 Before transplanting, roots treatment should be done with a good systemic
fungicide to reduce incidence of fungal diseases during establishment.
 The optimum spacing is 15 cm between the rows and 10 cm between plants.

Nutrient Management
 One third of recommended N and full dose of P2O5 and K2O
are applied at the time of planting while remaining two
third N is applied in two equal splits at 30 and 45 days after
planting.
 In addition to NPK, sulphur & Zinc are also essential plant
nutrients important for onion crop.
 Application of 15-30 kg S/ha as basal dose at the time of
transplanting is sufficient for optimum production of onion.
 Foliar application of Zn @ 0.5% at 45 and 60 days after
transplanting improves nutritional quality of onion bulbs.
Weed management
 Onion is infested with diverse flora of weeds.
 Onion crop has very poor competitive ability with weeds.
This is due to
 slow initial growth;
 lack of adequate foliage to smother weeds.
 Weeds have the ability to reduce bulb yield by 49-86%
depending on severity of infestation.

Weed Control
• Pre Emergence Herbicide –
1. Pendimethalin 30 % EC @ 1 – 1.5 L/Acre
2. Pendimethalin 37.8 % CS @ 700 ml/Acre
 Apply the Herbicide with 3 Days of Transplanting
 Prevent the crop from weeds by making a protective layer on the
soil surface thus inhibit the weeds from Germination.
Weed Control
• Post Emergence Herbicide
1. Propaquizafop 10% EC @ 250 ml/Acre
2. Quizalafop 5 % EC @ 400 ml/Acre
3. Quizalafop 10 % @ 200 ml/Acre
 An excellent systemic selective, post emergence herbicide for control of
annual and perennial grassy weeds in broadleaf crops.
 Recommended for post emergent use at 2 to 3 leaf stage of weed
growth
 One hour rain fastness and enhanced activity on target weeds.
4. Oxyfulorfen 23.5 % EC @ 100 – 150 ml/Acre
 An excellent pre-emergence and directed post-emergence contact
herbicide.
 It provides selective control of most annual broad-leaf weeds and some
grassy weeds.
 Sunlight is essential for performance of Oxy Gold.
Insect Pest Management
Onion Thrips (Thrips tabaci)
With continuing leaf growth, these feeding
points elongate to give the typical onion
thrips symptoms: whitish spots & streaks on
the leaves.
Intensive feeding results in silvery-white
stippled appearance referred as white blast
or silver top.
Seedlings may be killed if large numbers of
thrips are present.

Basal rot can continue in storage.
Sometimes the bulb appears healthy from
outside, but inner side sheaths are rotten.
Management
 Saaf 500 g/Acre
 Sprint 500 g/Acre
 Full stop 250 g/Acre
 Folicur 250 ml/Acre
 Mix Activator 5 ml/15 litre for better control
Disease Management
 Neck Rot (Botrytis allii)
 Decay of bulbs from the neck downwards
 Scales of diseased bulbs become soft & brown, giving

  • 7. Nursery Raising  Seed Rate: 8 – 10 Kg/Ha  Proper nursery management and transplanting are important operations in the onion crop.  About 0.05 hectare nursery bed area is enough for getting seedlings to transplant in one hectare.  Field should be ploughed 5-6 times to break clods and well pulverized to hold water.  The debris of previous crops, weeds and stones should be removed before bed preparation.
  • 8. Main Field Preparation  Prior to transplanting, field should be ploughed & disked properly to eliminate debris and soil clods.  Organic manures equivalent to 75 kg nitrogen/ha should be incorporated at the time of last ploughing and beds with appropriate size should be prepared after levelling.  Water logging favours Anthracnose which is a devastating disease thus flat bed should be avoided.  Broad bed furrow (BBF) is best method for onion production as excess water can be drained out through the furrow.  BBF of 15 cm height and 120 cm top width with 45 cm furrow are best to achieve proper spacing and population density. It is suitable for drip and sprinkler irrigation as well.
  • 9. Transplanting  Proper care should be taken while selecting seedlings for transplanting.  Over and under aged seedlings should be avoided for better establishment.  At the time of transplanting, one third of the seedling top should be cut to get good establishment.  Before transplanting, roots treatment should be done with a good systemic fungicide to reduce incidence of fungal diseases during establishment.  The optimum spacing is 15 cm between the rows and 10 cm between plants.
  • 10. Nutrient Management N P2O5 K2O Kharif onion (Yield potential – 25-30 t/ha) Basal 25 kg 40 kg 40 kg organic manure equivalent to 75kg N (FYM – Approx. 15 t/ha or Vermicompost – Approx. 7.5 t/ha) Starter 10 Kg/Ha 30 DAT 25 kg - - Humino 5 – 7.5 Kg/Ha 45 DAT 25 kg - - - Total 75 kg 40 kg 40 kg - Late Kharif and Rabi onion (Yield potential- 40-50 t/ha) Basal 40 kg 40 kg 60 kg organic manure equivalent to 75kg N (FYM – Approx. 15 t/ha or Vermicompost – Approx. 7.5 t/ha) Starter 10Kg/Ha 30 DAT 35 kg - - Humino 5 – 7.5 Kg/Ha 45 DAT 35 kg - - Total 110kg 40 kg 60 kg
  • 11. Nutrient Management  One third of recommended N and full dose of P2O5 and K2O are applied at the time of planting while remaining two third N is applied in two equal splits at 30 and 45 days after planting.  In addition to NPK, sulphur & Zinc are also essential plant nutrients important for onion crop.  Application of 15-30 kg S/ha as basal dose at the time of transplanting is sufficient for optimum production of onion.  Foliar application of Zn @ 0.5% at 45 and 60 days after transplanting improves nutritional quality of onion bulbs.
  • 12. Weed management  Onion is infested with diverse flora of weeds.  Onion crop has very poor competitive ability with weeds. This is due to  slow initial growth;  lack of adequate foliage to smother weeds.  Weeds have the ability to reduce bulb yield by 49-86% depending on severity of infestation.
