Abstract

A cultivation trial of winged bean under its popularisation programme has been undertaken on marginal sodic soils. The study showed no abnormality at any stage of the culture and the food value of the produce was concurrent with those reported in literature. The seed production (0.7–1.56 tons/hectare) was in accordance with the average yield obtained in other tropical countries. The highest seed yield (2.199 tons/hectare) was obtained when the seeds were sown at 32.4 cm2 spacing. Staked crops yielded 73% more seeds. The oil (18%), free from parinaric acid, and protein (28.8% on the seed) contents of the seed tally with the values reported elsewhere. The seed oil can be stored for a longer time without any change in its quality.
