Abstract:Yam production is encouraged in Cameroon to meet with demands and stop importation. This study, initiated to guide farmers, resulted in a local collection of 114 'types' within nine yam species from which, using the classification characters of Lawton (1967) for species and Martin (1973) for cultivars. 68 cultivars including 10 elites adapted to different agricultural zones, were selected. Agronomic work contains information on optimum planting density, sett weight on the advantage of staking, responses to fertilisers, and the effect of seedbed. Economically, a yield of 10.87 tons/ha, was necessary to break even. Labour inputs were 390 mandays plus 24 tractor hours per hectare with harvesting (32%) and hand-hoe weeding (30.8%) as the main components. Fig., notes, ref., French sum.
