BRIEF DESCRIPTION A vigorous, twining vine reaching 6-9 m in length, with large deep tap roots, trifoliate leaves, and white to blue flowers. Variety lablab has long tapering pods, while variety lignosus has shorter pods. USES Grown for forage, green manure, and soil improvement. Young pods are eaten as snapbeans or cooked and eaten as vegetables. Dried seeds are edible. Fresh seeds contain poisonous prussic acid and must be thoroughly cooked before eating. KILLING T 0 to 3°C. Some early flowering varieties can be grown in frost-prone regions because the seeds mature before the onset of the frost in the fall. GROWING PERIOD Short-lived perennial often grown as an annual, in the the tropics it can persisting for two years or more, early cultivars may be harvested after 70-120 days and late cultivars after 140-210 or up to 300 days. A second crop may be obtained when the plants are treated as a short duration perennial.

FURTHER INF Scientific synonyms: L. niger, L. vulgaris, L. leucocarpus, L. mankinicus, L. perennans, Dolichos lablab, D. biflorus, D. purpureus, D. albus, D. cultratus. Hyacinth bean is native of India. It can in the tropics be grown at altitudes between sea level and 2100 m, but it perform best at lower elevations. Most cultivars are adapted to high temperatures and cool weather may adversely affect fertilization. The production extends south to beyond 30°S. Short day cultivars flower best with less than 11 hours of daylight, but also long-day cultivars exist. Photosynthesis pathway C 3 II. Hyacinth bean accept a wide range of humidity. Optimum yield is 2.5 t/ha of dry seed, while the average yield in India is about 1.4 t/ha. Optimum yield of green pods is 7.5 t/ha and the average yield in India is 2.6-4.5 t/ha. Fodder yields are about 25-40 t/ha of fresh material or 5-11 t/ha of dry matter.
