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
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

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
|Time of application||Urea kg/ha||TSP kg/ha||MOP kg/ha|
|Basal (02 days before planting)|
|Top Dressing One (4weeks after planting)|
|Top Dressing One (10 weeks after planting)|
Irrigate crops once a week in dry weather. In sandy soils irrigate the crops less frequency

- Improve water drainage system
- There is no chemical treatment for bacterial diseases
- Have to improve sanitary condition in the field
