In South Kivu, and particularly in Kabare territory, cassava plays an important role in the diet of the population and is considered a staple crop. This study was undertaken to characterize cassava farms and to evaluate different elements of farmer characteristics influencing the adoption of improved cassava varieties in Kabare territory. To achieve this, data collected from 150 cassava producers were processed and analyzed. Using the Probit model, the factors influencing the adoption of improved cassava varieties were determined. Emphasis has been placed on the characteristic factors of the producer himself. The results obtained show that adoption rate of improved varieties is low overall (34.6%). Only the improved varieties Sawa sawa (25.9%) and Liyayi (7.9%) and Mayombe (0.7%) are adopted in the area. Among the reasons influencing the non-adoption of these varieties, agricultural producers mention roots rot, lack of cassava cuttings and theft of plants. Most adopters of these varieties, however, do not recognize the true tolerance of these varieties to the African mosaic of cassava. Variables such as level of education, length of service in cassava cultivation, age, sex, membership of a peasant organization are those that determine the adoption of these varieties. Only the first 2 variables proved to be more important. Thus, taking these factors into account as well as accompanying measures and appropriate extension techniques would improve the household food supply in the territory of Kabare.
