Winged Bean

Psophocarpus tetragonolobus

Belongs to family fabaceae. This crop can be grown in areas up to 2000m from mean sea level. Even though local selections of winged bean produced fruit in Maha due to photo sensitivity, new varieties have been developed to give yield throughout the year

Released Varieties

Climatic requirements/ Areas suitable for cultivation

Temperature range from 18 – 32 oC is suitable for better performance.

Can be grown in any area up to 2000m from mean sea level.


Well-draining sandy loam or clay loam soil with organic matter is ideal. But can be grown in sandy soils as well as clay soils

Seed requirement

21-23 kg /ha

Nursery Management

Direct seeding

Plant seeds at the onset of rainy season or can do planting if there is enough irrigation facility.

Land preparation

Harrow the soil deeply and break soil. If water retains in soil, prepare high beds or ridges to plants seeds. Mark pits according to given recommendations.


Soak seeds in water for about 24 hours before planting for better germination. Better if can apply a fungicide like “Captan” as a seed treatment. Plant 3-4 seeds per pit.

After 2 weeks of seedling emergence, keep 2 healthy plants and remove the rest


Plant 7 ft. poles near pits for support of vines.

Train the vines to poles


75 cm x 60 cm between rows and plants respectively.


Add 10t/ha of well decomposed organic matter. Additionally apply chemical fertilizer as recommended. Apply basal fertilizer 2-3 days before planting

Pest Management

Disease Management

Causal Organism : Ralstonia solanacearum


Instant wilting can be seen in the plant even at the optimum level of water in the field. Oozing can be observed when stem part ( near to the root) dipped in water


  • Remove infected plants with soil.
  • Improve water drainage system
  • There is no chemical treatment for bacterial diseases
  • Have to improve sanitary condition in the field


Harvest pods every 3-4 days

First harvest of recommended varieties can be taken in 70-75 days. But most cultivated local varieties, this can take up to 90-100 days.

Harvesting can be done 6-7 weeks from first harvesting.
