Agricultural underproduction in our country is largely linked to a lack of adequate structural organization of peasant farmers of food crops. This insufficiency plunges our especially rural environments into an almost chronic undernourishment. This study deals with the cassava sector in the Groupings of Irhambi-Katana and Bugorhe, in the territory of Kabare, Province of South Kivu in DR Congo. These two Groups produce a lot of cassava grown and consumed by almost all households but which is sold at a low price and only traders and processors derive a good profit from it in our communities to the detriment of producers. The data for this study were collected using the techniques of simple and participatory observation, the questionnaire, survey, documentation, and the chi-square test. The methods used are: the statistical method, the analytical, the descriptive and the synthetic method. This work responds to the questions and research objectives formulated in advance. We used Microsoft Word and Excel to enter the texts and process the data. Our hypotheses were tested by the statistical results of Chi-square. The study identifies and analyzes the main difficulties of cassava related to production, marketing and its by-products. These difficulties handicap the socio-financial profitability of this product, which penalizes their poorly or unorganized producers. To make it profitable, it is necessary to organize their producers in a promising sector so that they are able to improve farming techniques and transform this cassava into high quality flour. The success of this strategy is possible if our development partners adheres and and that they strongly support the organization and proper functioning of promising agricultural sectors.
