        The winged bean can be grown in poor, sandy or clay soils without added fertilizer. The plant is one of the best nitrogen fixers ie, it has an ability to fix nitrogen from the atmosphere and improves fertility of the soil. The plant requires very little or no fertilizers.

The seeds have a hard coat and it helps to soak them before planting to hasten germination. The plant grows very quickly. After sowing, it takes 8 to 10 days to sprout. After 8 to 10 weeks, the creeper will bear flowers, violet in colour. Within 4 weeks, tender beans will grow. Pod-bearing will last for 2 to 3 months. One creeper will bear 4 to 5 kilos of beans. The creeper has a well-developed root system. From it, the plant will sprout again in the next season. Yields of fresh pods are normally between 10-15 tons per hectare.

FOOT NOTE:-
According to Duke, 1981; and Oomen and Grubben 1977, winged bean leaves can produce about 8,000 kg/ha in 60 days or less. This comes to 135 kg/ha per day. This comes to about 63,500 calories; 6.75 kg of protein; 108 grams of calcium; 2.7 grams of iron; 4.1 grams of b-carotene; and 39,150 mg of vitamin C per hectare per day.
