**6. Conclusion**

Onions and potatoes are market garden produce that are produced mainly during the dry season. The production of these two crops has increased sharply in recent years as it represents a major source of income for rural populations in Burkina Faso who are mostly poor. The current situation of the local market for these products characterized by a single production cycle makes it difficult to offer products throughout the year. A large part of the production is put on the market of the harvest to avoid the losses postharvest due to the lack of adapted storage infrastructures. To improve farmers' profit margins and maintain product quality throughout the year, local innovators have created new conservation technologies. These new technologies need to be valorized because they are not sufficiently known by the users who are the producers and the sellers. The valorization of technological innovations must aim for a structural transformation of the economy. The analysis of the national environment shows in a general way an environment favorable to the valorization of the innovations. The results of the surveys show that many agricultural producers are not yet aware of the technological innovations of onion and potato conservation. These producers are weakly alphabetized. The lack of training of many producers and the high cost of innovations can limit the use of innovative technologies. Econometric estimation of the determinants of the farmers' perception of Tilgr-Baore technology indicates that educational level and information availability have a positive and significant influence on the perception of Tilgr-Baore, while farm size negatively influences the probability of a very good perception of technology.

For a better dissemination of new technologies for onion and potato conservation, public policies must revitalize the partnership between ministerial departments involved in the promotion of innovations and innovators. In addition, public policies should encourage the promotion of innovation protection and speed up the process of obtaining patents to ensure the transfer of technological innovations. The adoption of innovations requires an improved perception of innovation. To do this, it is necessary to improve the level of education of farmers and make available information on innovations. Farmers' organizations are the main channel for transmitting information on the existence of innovations. It is an element of the social capital of the farmer that needs to be strengthened. Our results also imply that policies to promote new technologies adoption (mainly the Tilgr-Baore) should target small farms as a priority.
