“…Like other vegetative propagated crops, yams are cultivated and maintained by farmers for their agrobotanical, taxonomic or gastronomical characteristics, and because of that, several names are assigned to new local varieties when they are introduced in the homegardens (Chair et al, 2010). Some authors (Asemota et al, 1996;Dansi et al, 1999;Pedralli et al, 2002) observed a considerable variation in linguistic terms in the nomenclature of the local yam varieties, where each location has its own variable names for different cultivars.…”

Widely spread in the tropics, yams were introduced into Brazil during the colonial period and are currently grown throughout the country. Despite its importance as a pharmacological and food source, there is a lack of studies describing how and where this tuber is grown in Brazil. The aim of this study was to provide an overview of the cultivation and distribution of Dioscorea alata in different Brazilian regions. A total of 63 farmers were visited in different municipalities and communities in four regions in the country: South, Southeast, Northeast and Midwest. Semi-structured interviews were conducted to collect socio-economic, use, management and diversity data for this crop. The majority of interviewers were men, married, with children, using retirement benefits and agriculture as income and family labour as the main support in the yam cultivation. A wide distribution of this species was found, with the occurrence of D. alata in the four sampled regions. A variety of vernacular names for this species was collected, differing according to the region where it is cultivated. Most farmers cultivate yams in fields, however an increased usage of home gardens for the cultivation of this tuber was found. Also, most farmers cultivate yams in association with other crops in areas of different sizes and slash and burn practices, although mostly disappearing, are still being used by many farmers. The results of this study provide more concrete data on the distribution and diversity of this important crop.Keywords: agroecological diversity, Dioscorea, ethnobotany, in situ conservation, tubers. Distribuição, manejo e diversidade de variedades locais de inhame no Brasil:um estudo em Dioscorea alata L. ResumoAmplamente difundido nos trópicos, o inhame entrou no Brasil na época da colonização e atualmente é cultivado em todo o país. Apesar de sua importância como cultura alimentícia e farmacológica, são raros os estudos que identifiquem como e onde esse tubérculo está sendo cultivado no Brasil. Este estudo teve como objetivo apresentar um panorama do cultivo e distribuição da espécie Dioscorea alata L. em diversas regiões do Brasil. Para tanto, foram visitados 63 agricultores em diferentes municípios, distribuídos entre o Sul, Sudeste, Nordeste e Centro-Oeste do país. Foram realizadas entrevistas semi-estruturadas, nas quais foram levantados dados socioeconômicos, bem como sobre o uso, manejo e diversidade dessa espécie. A maioria dos entrevistados eram homens casados, com filhos, que possuíam aposentadoria e a agricultura como principais fontes de renda. Constatou-se que a mão-de-obra familiar está bastante envolvida com o cultivo de inhame. Uma ampla distribuição da espécie foi observada, com a ocorrência de D. alata nas quatro regiões amostradas. Grande diversidade de nomes populares foi observada para a espécie neste estudo, com diferenças na nomenclatura popular em função das diferentes regiões onde a mesma é cultivada. A maioria dos agricultores cultiva inhame em roças, no entanto a importância dos quintais fo...

The genus Dioscorea comprising over 650 species distributed throughout the World's tropical, subtropical and temperate regions [2][3]. The Dioscorea genus includes an important group of tropical food yams, the edible portion of which is the tuber, and occasionally the bulbil.…”

Objective: Protection from oxidative damage to the tissues is provided by natural or synthetic antioxidants. Because of the multiple mechanisms of actions and presence of various phytochemicals, plant-based antioxidants are preferred. Dioscorea is well known as a traditional edible tuber. The present study was undertaken to explore and highlights the nutritional benefits and to evaluate the in vitro antioxidant and free radical scavenging capacity of ethanolic extract of three different underutilised Dioscorea species (D. alata, D. pentaphylla and D. oppositifolia) with a common cultivated crop, Plectranthus rotundifolius.Methods: Different processing methods are adopted to assess their influence on nutritive value and antioxidant properties. Tubers were studied for proximate composition using standard analytical methods. Mineral elements were analysed using ICP-MS (Inductively Coupled Plasma-Mass Spectrometer). Antioxidant potential of raw and processed samples was determined using a range of in vitro models. Results:The presence of essential minerals such as Na, K, Ca, P, Zn and Mn were observed. High radical scavenging activity was observed in the tubers of Dioscorea. Results indicated that phenolic compounds are the significant contributors to the antioxidant activity. Conclusion:Current study suggests that Dioscorea might be a promising natural antioxidant and could be very useful health food, as they enhance the antioxidant defence system. It also proposes that underutilized tubers can efficiently contribute to the nutritional requirement and food security.

“…More than 800 species of Araceae have economic (ornamental, edible or medicinal) or ethnobotanic importance, and about 10% of the world population use as food ingredient the taro rhizome Colocasia esculenta (L.) Schott, popularly known in most countries like "taro" (Pedralli et al 2002). Due to peculiar characteristics such as rusticity and nutritional values, taro is a tuberous species suggested by FAO (Food and Agriculture Organization) as an alternative crop to increase the food base in developing countries .…”

The experimental studies were conducted in 2007-2008, 2008-2009 and 2009-2010 crop seasons, in order to know the agro-economic yield of 'Chinês' and 'Macaquinho' taro clones, propagated using huge, extra, large, medium, small and tiny cormels. The harvest was done on average on 202 days after planting, in three crop seasons. Based on the joint analysis of variance carried out, it was observed that taro clones showed signifi cant differences in the yield of fresh and dry weight of leaves, cormels, and commercial and non-commercial comels; besides, there were signifi cant differences in yield of a crop season to another and the size of the cuttings induced signifi cant differences in yield. In the conditions that the experiments were conducted, and considering the highest average yield of fresh weight of commercial cormels (28.69 t.ha -1 ) and highest net income (US $14,741.14) correspondent to the three crop seasons, it is recommended to cultivate 'Macaquinho' clone using small cuttings in propagation.
