It is difficult to save seed in the wet tropics. If plants are planted in a hole 10-15 cm deep they develop long white edible stalks. The soil should be mounded up around the base of the plant. A spacing of 15-20 cm between plants and in rows 30-36 cm apart is suitable,

Production

Plants are ready for harvest after 16-20 weeks. A yield of 20 kg per 10 metres square is average.
