Improving yam production by mineral fertilisation in the savanna zone of Cote d'Ivoire


, : Improving yam production by mineral fertilisation in the savanna zone of Cote d'Ivoire. Savanes africaines: des espaces en mutation, des acteurs face a de nouveaux defis Actes du colloque Garoua, Cameroun, 27-31 mai 2002: 5-26

Cote d'Ivoire is the second producer of yam after Nigeria with 2.8 millions tons produced per year. Though its farmers are still looking for 'virgin' soil to increase their yields. Mineral fertilizer application study led in the savanna zone has as objective to determine the response of local yams to mineral fertilizers. Thus, four local varieties (Bete bete, Gnan, Krengle and Wacrou) were tested with two fertility levels.
