Taux et déterminants de l’adoption des technologies agricoles : cas des

In spite of the socio-economic importance of yam, his production is still facing serious constraints as no availability and inadequacy of seed tubers. In order to cope with these constraints, International of Tropical Agriculture (IITA) has developed improved varieties of which we have TDrs’ varieties. Many years after their extension in Benin, it’s then important to evaluate their adoption rate and identify factors which determine this adoption. This study’s aim is to contribute to this evaluation. Data used came from 202 yam producers randomly selected in villages pertain to Borgou and Collines’s regions. The framework developed by Reed et al. (1991) and the counterfactual outcomes framework estimating the Average Treatment Effect have been respectively used to analyze on the one hand yam producers’ perceptions and on the other hand the rate and determinants of the TDrs varieties’ adoption. Results indicate that the information rate is 44 % and the main factors determine information access are the participation on trials activities, being member of yam producers’ association, contact with extension agents and the revenue proving by yam production. The results also reveal that aptitude to a good pounded yam, yield, markets value and aptitude to be consumed as boiled yam are the main criteria that yam producers are looked for when choosing any yam varieties. Aptitude to a good pounded yam remains the only criterion not met by the TDrs varieties promoting. The adoption of theses varieties is influenced by producers’ access to information, their age and their perception about aptitude to be transformed in chips and markets value. The TDrs population adoption rate is estimated to be 37 % in 2007 and is projected to reach up to 65 % in the long term.
