Production et coûts des semences utilisées pour l'amélioration des jachères et des aménagements antiérosifs : "Le cas des zones de savane du Nord Cameroun"
Abstract
Seeds Production for Fallow and Anti-Erosion Management : "The Case of the Savannah Areas in North Cameroon". The maintenance of cultivated soils' fertility in North Cameroon relies on the extension of the techniques of water erosion control and improved legume crop fallows. These innovations require that seeds must become available to farmers. These seeds are legume seeds (Calopogonium mucunoides, Stylosanthes hamata, Mucuna pruriens, Cajans cajan) or perennial grasses (Panicum maximum, Andropogon gayanus, Cenchrus ciliaris). On station research has developed the techniques of seeds production which can be introduced in the farmer's environment on the one hand, and on the other hand can be used to evaluate the cost of legumes seeds production. Depending on the species, the total price of seeds production varies from 250 to 1160 FCFA/kg (0, 5 U$ to 2 U$/kg). Based on these prices, it seems possible in the first step to diffuse these seeds varieties. The diffusion of the vegetal material depends firstly on the interest that farmers attach to techniques of soil restauration which are proposed to them. If they adopt these innovations, they can easily produce seeds that they need after been trained to the techniques developed by research.
