What it needs

Soil, sun and warmth

  • Soil pH2,3Part of this comes from the sources cited. The rest is an AI suggestion.

    5.5 to 7

    Well drained, medium to deep loam or clay loam. Lime acid soil before sowing. It does not stand waterlogging.

  • Sunlight3Part of this comes from the sources cited. The rest is an AI suggestion.

    At least 6 hours a day

    Full sun in an open field. In places where the sucking bug is common, avoid sowing in shade.

  • Temperature2,3Part of this comes from the sources cited. The rest is an AI suggestion.

    Grows best at 15 to 25 °C

    Frost: none tolerated.

Water and feeding

WateringNo published guide covers this for the North-west plains, so this is an AI suggestion. Check it with local advice before you rely on it.

Water lightly after sowing if the soil is dry, then every two to three weeks. Rajma roots shallowly and needs more water than gram. Do not let it go dry at flowering and pod filling, and never let water stand in the field.

WeedingNo published guide covers this for the North-west plains, so this is an AI suggestion. Check it with local advice before you rely on it.

Keep the field clean for the first six weeks. Hand weed or hoe about three and six weeks after sowing, and earth up lightly at the second weeding.

Pests and diseasesNo published guide covers this for the North-west plains, so this is an AI suggestion. Check it with local advice before you rely on it.

Organic and cultural controls only.

  • Pest

    Aphids

    Signs

    Small soft insects in groups on young shoots, leaves and pods. They suck sap and spread mosaic virus.

    What to do

    • Pull out and destroy badly infested shoots early
    • Encourage ladybird beetles, which feed on aphids
  • Pest

    Pod borer

    Signs

    Caterpillars bore into pods and eat the seeds, leaving round holes.

    What to do

    • Hand pick and destroy caterpillars and bored pods
    • Set up bird perches in the field
  • Pest

    Bean stem fly

    Signs

    Young plants wilt and die; the stem near the soil is swollen and tunnelled.

    What to do

    • Pull out and destroy wilted seedlings
  • Disease

    Anthracnose

    Signs

    Sunken dark spots with reddish margins on pods, stems and leaf veins; worse in wet weather.

    Prevention

    • Sow seed saved from a healthy crop
    • Rotate with cereals and do not grow beans in the same field every year
    • Destroy diseased plant remains after harvest
  • Disease

    Bean common mosaic

    Signs

    Light and dark green mottling and puckering of leaves; plants stay small and bear few pods.

    Prevention

    • Sow seed from a healthy crop
    • Pull out mottled plants early
  • Disease

    Root rot

    Signs

    Plants yellow and wilt; roots and the stem base turn brown and rot.

    Prevention

    • Sow on well drained land and avoid standing water
    • Rotate with cereals

Seed and the season's end

Saving seed1,3

Save seed from a healthy crop grown where anthracnose and bacterial blight do not occur.

When the seed is ready

Pods turn yellow, then brown and crisp, and most leaves fall. Early pods split if left too long.

Cleaning the seed

Pick early pods by hand as they ripen. Sun the plants for three or four days and thresh on a dry day by treading or beating the pods on a tarp.

Dry the grain again for three or four days, sort out damaged seed and store in a cool, dark, dry place. Watch for bean weevils.

After the last pickingNo published guide covers this for the North-west plains, so this is an AI suggestion. Check it with local advice before you rely on it.

Plough the roots and leftover stalks back into the soil after threshing; they add some nitrogen for the next crop. Follow with a cereal.

Destroy or deep plough the crop remains after harvest; they carry rust and root rot.

Rotation

Do not grow beans after beans. Rotate with cereals, and leave three years between bean crops where bacterial blight has shown up.
