The farmer of KANKU lives on agriculture and is disadvantaged by the institutional context, the lack of support infrastructure for his activity and finds himself in difficulty to manage and market his production. This study was carried out in order to evaluate the management and marketing mode of this KANGU farmer's harvest products in order to identify the factors that can enable him to better manage this production and make better use of it. A structured survey was carried out in 5 localities of the KANGU group. This survey used simple and statistical random sampling methods, accompanied by empirical analysis for data collection. A statistical analysis was carried out for the processing of the raw data. After this analysis, it appears that this farmer produces for two purposes in particular self-consumption and marketing. A large proportion, more than 59% of the production of basic commodities, is destined for marketing and barter with 76.1% is the mode of marketing most practiced in this environment by the farmer despite being unfavorable for the farmer. The lack of support infrastructure (specific market, evacuation routes, etc.) is what compels the producer to resort to this mode of exchange.
