Abstract

: Nigeria is a country endowed with enormous food and agricultural resources such as yam, cassava, cocoa, rice, sugar cane, maize and millet. In the early years of Nigeria’s independence, cash crops such as rubber, cashew, groundnut and oil palm were the major crops around which the economy revolved. Today, there is a shift to alternatives for biofuel, pharmaceutical starch and derivatives using root and tuber crops, which have continued to play a significant role in the agricultural revolution of the country. The current agricultural transformation agenda in Nigeria is intended to engineer the bulk of root and tuber crops in the country into value-added products to match the increasing new tastes and demands for products across the globe. It is also intended to provide job opportunities and to generate additional income for low-income earners, especially in the rural areas. There is, therefore, the need to intensify research efforts aimed at exploring the potentials of major and minor root and tuber crops to ensure food security. In this review, six (6) major root and tuber crops, namely cassava ( Manihot esculenta Crantz), yam ( Dioscorea spp.), sweet potato ( Ipomoea batatas (L.) Lam), potato ( Solanum tuberosum L.), cocoyam ( Xanthosoma sagittifolium Schott) and ginger ( Zingiber officinale L . ) as well as three (3) minor ones, namely the Hausa potato ( Solenostemon rotundifolius (Poir) J. K. Morton), Livingstone potato ( Plectranthus esculentus N.E.Br.) and the Polynesian arrowroot ( Tacca leontopetaloides (L.) Kuntze) were examined. In spite of the numerous benefits derivable from these crops in terms of nutrition and medicinal values, some have been neglected to the extent that they are classified as orphan crops. Therefore, much more attention should be accorded to these crops, which have the potentials to contribute to food security in Nigeria.
块根和块茎作物对粮食安全的贡献
尼日利亚是一个粮食和农业资源丰富的国家,如山药、木薯、可可、大米、甘蔗、玉米和小米。在尼日利亚独立的早期,经济作物如橡胶、腰果、花生和油棕是经济的主要作物。如今,生物燃料的替代品、药用淀粉和使用块根和块茎作物的衍生物正在转变,这些作物在该国的农业革命中继续发挥着重要作用。尼日利亚目前的农业转型议程旨在将该国的大部分块根和块茎作物改造成增值产品,以满足全球对产品日益增长的新口味和需求。它还旨在提供就业机会,并为低收入者创造额外收入,特别是在农村地区。因此,有必要加强研究工作,以探索主要和次要块根和块茎作物的潜力,以确保粮食安全。本文综述了六种主要的块根和块茎作物,即木薯(Manihot esculenta Crantz),山药(薯蓣属),甘薯(Ipomoea batatas (L.))。红薯(Solanum tuberosum L.)、椰子树(Xanthosoma sagittifolium Schott)和姜(Zingiber officinale L.)还有3种较小的品种,即豪萨马铃薯(Solenostemon rotundifolius (Poir) J. K. Morton)、利文斯通马铃薯(Plectranthus esculentus N.E.Br.)和波利尼西亚芋(Tacca leontopetaloides (L.))。Kuntze)进行了检查。尽管这些作物在营养和药用价值方面有许多好处,但有些作物被忽视了,以至于被归类为孤儿作物。因此,应该更加重视这些作物,因为它们有可能促进尼日利亚的粮食安全。
