Advisory for the Month of November 2026

This is time for harvesting kharif onion crop. Late kharif onion crop is presently standing in farmers’ fields. The farmers also have 10-15 days old rabi onion seedlings in nursery and garlic and onion seed crop in their fields.

A. For harvesting kharif onion crop

  1. Kharif onion crop should be harvested at 100-110 days after transplanting depending on variety. Neck fall need to be created by using empty barrels two or three days before harvesting.
  2. Harvested bulbs may be left in the field for three days for curing.
  3. After three days of field curing, the tops should be removed leaving 2 - 2.5 cm stalk above the bulbs and bulbs should be shade cured for 10-12 days.
  4. If there is a likelihood of rains for 2-3 days, the crop may be harvested at 90-100 days after transplanting and sold in market immediately.

B. For standing late kharif onion crop

  1. If there is excess water due to rain, drain it out.
  2. First top dressing of nitrogen @ 35 kg/ha may be applied at 30 days after transplanting.
  3. Hand weeding should be done at 40-60 days after transplanting.
  4. Second top dressing of nitrogen @ 35 kg/ha may be applied at 45 days after transplanting.
  5. Foliar application of micronutrient mixture (5 g/L) is recommended at 30, 45 and 60 days after transplanting.
  6. If there is a forecast for two-three days rainfall, more than 85% relative humidity and cloudy condition, the farmers are advised to give first prophylactic spray with benomyl @ 0.2% to control anthracnose disease.
  7. Second spray with methomyl (0.8 ml/L) along with mancozeb (2.5 g/L) after 15 days of benomyl spray is recommended, if required. This will take care of foliar diseases and thrips incidence.

C. For rabi onion nursery

  1. Hand weeding is recommended 20 days after sowing.
  2. 2 kg N /500 m² should be applied after hand weeding.
  3. Application of water through drip or micro sprinkler irrigation system is recommended.
  4. Drenching of metalaxyl @ 0.2 % is recommended to control soil borne diseases.
  5. When the severity of thrips infestation is high, foliar application of fipronil/profenophos @ 1 ml/L is recommended.
  6. Foliar application of mancozeb/tricyclozole/hexaconazole @ (0.1%) is recommended to control foliar diseases.

D. For standing garlic crop

  1. First top dressing of nitrogen @ 25 kg/ha may be applied at 30 days after planting.
  2. Second top dressing of nitrogen @ 25 kg/ha may be applied at 45 days after planting.
  3. Hand weeding should be done at 40-60 days after transplanting.
  4. Foliar application of micronutrient mixture (5 g/L) is recommended at 30, 45 and 60 days after planting.
  5. First prophylactic spray with carbosulfan (2 ml/L) along with tricyclazole (1 g/L) is recommended.
  6. Second spray with methomyl (1 ml/L) along with mancozeb (1 g/L) is recommended after 15 days of first spray, if required.
  7. Third spray with profenophos (1 ml/L) along with hexaconazole (1 g/L) is recommended after 15 days of second spray, if required.

E. For standing onion seed crop

  1. Hand weeding should be done at 40-60 days after planting.
  2. First top dressing of nitrogen @ 30 kg/ha may be applied at 30 days after planting.
  3. Second top dressing of nitrogen @ 30 kg/ha may be applied at 45 days after planting.
  4. First prophylactic spray with meyhomyl (1ml/L) along with tricyclazole (1 g/L) is recommended.
  5. Second spray with profenophos (1 ml/L) along with mancozeb (1 g/L) is recommended after 15 days of first spray, if required.
  6. Third spray with carbosulfan (1 ml/L) along with hexaconazole @ (1 g/L) is recommended after 15 days of second spray, if required.

F. For stored rabi onion and garlic bulbs

  1. Monitor stored bulbs regularly for sprouting and rotting. Rotted and bruised bulbs if any should be removed immediately. Make sure that ventilation is proper.
  2. Onion bulbs should be spread properly with heap height up to 4-5 feet only.
  3. Garlic bulbs with leaves should be stored in ventilated storage structure by hanging or in circular heaps tapering towards top.
Note: Carbosulfan, profenophos, fipronil and methomyl are recommended only when the thrips damage is visible. Mancozeb, hexaconazole, propiconazole and tricyclozole are recommended only when the disease incidence is visible.
