The purpose of this book was to contribute to a better understanding of the problems related to cassava production in Nkolo on the one hand, and on the other hand to determine the cultivation system practiced, in order to identify the constraints related to the lack of technology transfer from Research in Nkolo. After conducting surveys among farmers, we are convinced that cassava producers are mostly adult women and that the most dominant age group is between 36 and 55 years old. The majority of producers have been growing cassava for 11 to 20 years and their main source of income is the field. Most producers have little knowledge of the main diseases of cassava, the majority of producers sell cassava after having transformed it into fufu or Chikwanges, then the producers of cassava of Nkolo in general are not affiliated in the development associations and they have a difficulty to work because the majority of the producers work manually because of the lack of working tools.
