    Last picking3

Water before sowing if the soil is dry, and lightly two or three days after sowing. With irrigation, water first about 25 days after sowing and then about every 25 days, six or seven times in all. Do not let the crop go dry before and during flowering and while pods fill, and never let water stand.3

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

Watering3

Water before sowing if the soil is dry, and lightly two or three days after sowing. With irrigation, water first about 25 days after sowing and then about every 25 days, six or seven times in all. Do not let the crop go dry before and during flowering and while pods fill, and never let water stand.

Weeding3

Weed 20 to 25 days and 40 to 45 days after sowing, and earth up the plants after each weeding. The first weeks matter most.

Good neighbours1,3

Pests and diseases1,3

Organic and cultural controls only.

  • Pest

    Aphids

    Signs

    They suck sap from leaves and pods and carry mosaic virus from plant to plant.

    What to do

    • Grow a tall border crop such as mustard around the field
    • Put up yellow sticky traps, four to five an acre
    • Rotate with cereals rather than other legumes
  • Pest

    Pod borer

    Signs

    Caterpillars bore round holes in the pods and eat the seeds; they often hang half out of the holes.

    What to do

    • Grow marigold along the field edges as a trap crop
    • Release Trichogramma egg cards during flowering, one card for 200 m², three or four times, 7 to 10 days apart
    • Set pheromone traps, 12 a hectare
    • Put up 15 to 20 bird perches a hectare
    • Spray 5% neem seed kernel extract on young caterpillars
  • Pest

    Leaf miner

    Signs

    Grubs tunnel inside the leaves and leave white winding lines; badly mined leaves fall.

    What to do

    • Put up yellow sticky traps for the adult flies
    • Pick and destroy mined leaves early
  • Pest

    Blister beetle

    Signs

    Beetles eat flower buds and flowers, and sometimes young pods.

    What to do

    • Hand pick the beetles into a bucket of water, wearing gloves
  • Pest

    Whitefly and thrips

    Signs

    Whitefly sucks sap under the leaves and spreads virus. Thrips scrape young leaves and tips, which turn silvery and boat shaped.

    What to do

    • Put up yellow sticky traps (blue ones also catch thrips)
    • Protect ladybird beetles, which eat whitefly
  • Pest

    Cutworms

    Signs

    Caterpillars cut young plants at ground level at night and hide in the soil by day.

    What to do

    • Keep the field and bunds clean of grass and rubbish
    • Use only well rotted, dry farmyard manure
  • Pest

    Bihar hairy caterpillar

    Signs

    Hairy caterpillars feed in groups after rain and leave the leaves papery.

    What to do

    • Pick off egg masses and groups of young caterpillars with the leaves
  • Disease

    Anthracnose

    Signs

    Water soaked marks on pods turn into sunken brown or black spots with dark centres and red, yellow or orange edges. Pink spore masses show in wet weather. Young pods shrivel.

    Prevention

    • Sow healthy seed from places where the disease does not occur
  • Disease

    Angular leaf spot

    Signs

    Many small angular brown spots on leaves and pods give a checkerboard look; leaves yellow and drop early, and pods may be misshapen.

    Prevention

    • Sow healthy seed
    • Rotate crops where the disease has been seen
  • Disease

    Floury leaf spot

    Signs

    White, flour-like growth under the lower leaves at flowering; affected leaves drop early.

    Prevention

    • Sow healthy seed
  • Disease

    Bacterial blight

    Signs

    Appears early. See-through water soaked spots on leaves that turn yellow and die; reddish brown sunken spots on pods.

    Prevention

    • Get seed from an area where the disease does not occur
    • Rotate crops over three years
    • Grow rajmash with maize, which lessens the disease
    • Water at the base of the plants, not over them
    • Bury crop debris in the soil
  • Disease

    Rust

    Signs

    Small raised yellow spots, mostly under the leaves, grow into reddish brown pustules with a yellow ring.

    Prevention

    • Do not grow beans after beans; intercrop with cereals
    • Destroy crop remains after harvest
  • Disease

    Root rot

    Signs

    Long reddish purple marks on roots and the stem base turn black; plants stay small, wilt and die.

    Prevention

    • Sow early, on ridges, and drain the field well
    • Plough bean debris deep after harvest
    • Coat the seed with the bio-agent Trichoderma harzianum, 10 g per kg of seed

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 picking3

Destroy or deep plough the crop remains after harvest; they carry rust and root rot. Follow with a cereal, not another bean.

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.
