Item Underexploited tuber crops in Zimbabwe:(Horticultural Research Centre, 2002-01-01) Dhliwayo, Patient D.The Livingstone Potato iPlectranihus esculentus) is one of the edible indigenous tuber crops commonly grown under both dryland and wetland conditions in parts of the eastern districts of Zimbabwe. AIr" though the crop could be considered of minor importance globally in terms of total production and commercial value, it plays a significant role in human nutrition in different communities of some countries including Zimbabwe. In addition to its acceptance and nutritional value, the Livingstone Potato has been associated with certain therapeutic properties. A study was carried out on P. esculenius in the major producing areas of Zimbabwe to investigate the extent and importance of production of this crop. At least 15 varieties of the Livingstone Potato are currently grown under the farmers' traditional practices in the country. Scientific recommendations on the agronomy of this crop have neither been developed nor disseminated to growers-This lack of mechanisms for promoting and investigating this little known but potentially useful indigenous crop has constrained r-"improved production and utilization. ':;radual depletion of varieties is being ex- -:»:perienced and a massive effort isrequired to safeguard the survival of this orphaned genetic resource. The Livingstone Potato could become an important complement for other root and tuber crops if essential research needs, development and policy issues are addressed and satisfied. This report challenges researchers, policymakers and other related disciplines to assist in achieving a more efficient and balanced exploitation of P. esculentus.
