Agriculture stays the main activity of the populations of the Township of Ouaké.

This rotation of yam culture in the township of Ouake follows itself on two to three years the insufficiency of the arable earths. The production of the yam is always superior to the other speculations of 2006 to 2017. The season (2010 - 2011) recorded the strongest output (1285kg/ha) on a surface cultivated of 4749 ha. The different cultivated varieties are: the precocious varieties (Aloupa, Ankploman, Ekpètilè, HèAbalo, Walassi, Wotanam, Abota, Lalboko, Gbèm, Katala) and the belated varieties (Alasola, Ewotolo, Kokopo, Kpassa, Wolouchahabim, Toufou, Yelian, Loli, Djadjabiou, Adè, Agbantao, Adjanfa).

Abstract
Agriculture stays the main activity of the populations of the Township of Ouaké. The yam, Dioscorea alata, a rustic plant to spilled vegetative multiplication of by the diversity of its cultivated shapes in the world, is the main culture of this township. This survey aims to analyze the systems of production of the yam in the township of Ouake. To reach this objective, the methodological gait supported on the documentary research, the interviews, the investigations by questionnaires, the treatment of the data and the analysis of the results. The sample is constituted of 189 chosen individuals of way reasoned and is distributed on 06 precincts of the township. The SWOT tool has been used for the analysis of the results.Of the results of the present survey, it comes out again among others, that the yam doesn't cultivate itself in a successive way on a same parcel and stand always at the head of rotation.

Abstract: (french)
L’agriculture demeure la principale activité des populations de la Commune de Ouaké. L’igname, Dioscorea alata, une plante rustique à multiplication végétative répandue de par la diversité de ses formes cultivées dans le monde, est la principale culture de cette commune. Cette étude vise à analyser les systèmes de production de l’igname dans la commune de Ouaké. Pour atteindre cet objectif, la démarche méthodologique s’est appuyée sur la recherche documentaire, les entretiens, les enquêtes par questionnaires, le traitement des données et l’analyse des résultats. L’échantillon est constitué de 189 individus choisis de façon raisonnée et répartis sur 06 arrondissements de la commune. L’outil SWOT a été utilisé pour l’analyse des résultats.Des résultats de la présente étude, il ressort entre autres, que l’igname ne se cultive pas de façon successive sur une même parcelle et se place toujours en tête de rotation. Cette rotation de culture d’igname dans la commune de Ouaké se fait sur deux à trois ans suite à l’insuffisance des terres cultivables. La production de l’igname est toujours supérieure aux autres spéculations de 2006 à 2017. La saison (2010 – 2011) a enregistré le plus fort rendement (1285kg/ha) sur une superficie emblavée de 4749 ha. Les différentes variétés cultivées sont: les variétés précoces (Aloupa, Ankploman, Ekpètilè, HèAbalo, Walassi, Wotanam, Abota, Lalboko, Gbèm, Katala) et les variétés tardives (Alasola, Ewotolo, Kokopo, Kpassa, Wolouchahabim, Toufou, Yelian, Loli, Djadjabiou, Adè, Agbantao, Adjanfa). Les techniques de cultures restent toujours traditionnelles. Ces techniques ont eu d’impacts négatifs sur l’environnement. Des mesures ont été proposée dans cette étude afin d’améliorer les systèmes de production et la commercialisation.
