What it needs

Soil, sun and warmth

  • Soil pH1,2,4,13

    5.8 to 7.5

    Light, deep, friable and fertile soil with good drainage: sandy loam to clay loam rich in organic matter. Waterlogging, a high water table, and strongly alkaline or saline soils do not suit it. Sandy soil needs more frequent watering and extra manure.

  • Sunlight4,15

    At least 10 hours a day

    Needs good light: at least 10 hours a day for growth and bulbing. The kharif crop bulbs with 11 to 12 hour days, and clear sunny weather at harvest helps curing.

  • Temperature1,2,4,16

    Grows best at 13 to 25 °C

    Takes light frost.

    Monthly temperatures for the Arid west aren't in the library yet.

Water and feeding

Watering15

Little water just after establishment, rising to a peak about 3 months after transplanting. Water every 8 to 10 days early on, then every 4 to 6 days under drip; 8 to 12 waterings in a dry spell. Too much water, or water after a long dry spell, splits bulbs and causes bolting.

Weeding15

Weeds are a serious kharif problem while the crop is young. Do one or two hand weedings with light hoeing, which also loosens the soil and covers exposed bulbs.

Pests and diseases15

Organic and cultural controls only.

  • Pest

    Onion thrips

    Signs

    Spotted leaves that turn into pale white blotches; early attack can stop bulbing.

    Prevention

    • Intercropping, enough soil calcium, less nitrogen and sprinkler irrigation keep numbers down.
  • Disease

    Damping off

    Signs

    Delayed emergence; roots and stem base go water-soaked and thin, and seedlings rot.

    What to do

    • Mix Trichoderma viride into the nursery soil at 4 to 5 g per m².

    Prevention

    • Make nursery beds 15 cm high with good drainage; keep them moist, not soggy.
    • Solarise the bed under 250 gauge polythene for 30 days before sowing.
  • Disease

    Anthracnose (Colletotrichum gloeosporioides)

    Signs

    Pale yellow water-soaked spots spread along the leaf, with raised black dots; leaves shrivel and droop.

    Prevention

    • Destroy infected debris, keep the field clean, rotate for long periods and drain well.
    • Plant on raised beds, not flat beds, in kharif.
  • Disease

    Purple blotch (Alternaria porri)

    Signs

    Small white sunken spots that turn purple and eye-shaped with a yellow margin.

    Prevention

    • Avoid excess nitrogen and do not crowd the plants.
  • Disease

    Black mould

    Signs

    Black powdery spores on bulbs stored in hot weather.

    Prevention

    • Leave bulbs in the field for 2 to 5 days, then dry them in shade for 10 to 15 days.

Seed and the season's end

Saving seed1,2,5

Onion takes two seasons to make seed. Raise bulbs from seed in the first year, then plant these mother bulbs 45 x 20 cm apart in October; the seed crop is ready in April or May. Keep at least 1,000 m between varieties and pull out off-type and sick plants. Sun the mother bulbs for about 12 days before planting to kill downy mildew.

Onion seed stays viable for only about one year.

After the last picking15

Use long rotations away from onion: the anthracnose fungus survives on crop refuse.

Clear and destroy crop residues after harvest: the blight and anthracnose fungi survive on them.

Rotation

Do not grow onion on the same land year after year; keep 2 to 3 years between onion crops. As a winter crop it can follow cereals, groundnut or cowpea, and it does well after cauliflower, tomato or potato that got plenty of manure.
