Abstract

Intensive production programs of Jatropha curcas L. have been initiated in several West African countries, in order to increase and stabilize farmers’ incomes and also to produce biofuel. However, serious gaps in scientific knowledge on this crop could put at risk the chances of success for these programs. Therefore, the present work was undertaken to help better understand the germplasm diversity, farming systems and productivity of J. curcas in the Sudano-Sahelian environment. Parameters related to morpho-metric and chemical characterization of local accessions, on-farm surveys and agro-morphologic characterization of J. curcas were assessed. The results show that at farmer level, J. curcas is planted to increase income, but its integration into the production systems is performed through association with food crops or as hedgerows to delineate and protect fields. Fields dedicated only to J. curcas are still scarce and farmers invest minimal time and efforts for crop maintenance. The results also revealed a high variability among accessions for morpho-metric traits and oil content of seeds. Seed yield of J. curcas was low compared to projections made by common reports so far. This underlines the need to initiate research programs for breeding and improvement of the germplasm of J. curcas as well as development of appropriate technical packages for production in order to initiate a sustainable introduction of this crop into the farming systems of the Sudano-Sahelian zone.
