Edible Uses

Edible Parts: Leaves; Root; Stem.

Edible Uses: Condiment.

Tuber - cooked[22, 46, 61, 97, 171]. Very palatable and easily digested[1, 196], it is used as a staple food in some parts of S. America[2]. The root contains 10 - 25% starch, it is high in calcium and vitamin A[196]. It is used as a potato substitute, its flavour is between that of parsnips and sweet chestnuts with a hint of sweetness[2, 183]. The sweetness increases in storage[196]. The root is also used as the source of starch used in other foods[183]. The roots are harvested in the autumn and have a relatively short storage life[196]. Leaves. Used as a flavouring[177]. Young stems - raw or cooked as a vegetable[183, 196]. The stems are sometimes blanched and used like celery in salads[196].

Cultivation details

Prefers a good loam. Grows best in a sandy loam with a pH in the range of 5 to 6, in areas with about 1000mm of rain a year, requiring a minimum rainfall of about 600mm[196]. Tolerates a pH in the range 6.3 to 6.8. This species is not very hardy in Britain but it can be grown here as a half-hardy perennial, the roots being harvested in the autumn, stored overwinter in a cool frost-free place and planted out in the spring[1]. This species is often cultivated for its edible root in S. America, where there are many named varieties[2, 46, 61, 177]. Attempts in the 19th century to cultivate it as a commercial crop in Europe, however, were unsuccessful[2]. Plants take about 120 - 240 days from planting to produce a crop and 300 - 400 days to produce a crop of mature tubers[196]. At harvest time there can be as many as 10 tubers each the size of a carrot formed around the central root196]. One plant can yield 2 - 3 kg of edible roots, total yields of 40 tonnes per hectare are possible[196]. Preventing the plant from flowering can increase yields[196]. Plants might be sensitive to daylength, possibly requiring short days to initiate tuber production, and so may not be suitable for temperate climates. They also have a longer growing season than potatoes and are frost-tender so need a relatively long growing season[196]. Plants do not always produce viable seed in S. America[196].

Propagation

Seed - sow spring in a greenhouse and only just cover the seed. Do not allow the compost to dry out. Germination is often poor, less than 50%[196]. Since this species is believed to be a hybrid it will probably not breed true from seed. When large enough to handle, prick the seedlings out into individual pots and grow them on for the first year in a greenhouse and plant out in late spring after the last expected frosts. Division. Harvest the roots in the autumn, store overwinter and plant out in the spring. The plant forms a clump of tubers around a central root, each tuber can be used to grow a new plant. Traditionally the base of the tuber is repeatedly slashed to stimulate shoots to form and encourage a uniform arrangement of lateral roots. They are then left for a few days to heal before planting them out[196].

Seeds are not used for commercial production. The sprouts in the top of the roots must be used. The roots do not produce a new plant, as carrots also do not. I am a researcher of arracacha at Brazil. mariajbsgsmm@yahoo.com.br
