Abstract : A study on the cultivation techniques on cassava has been carried out in Yangambi. Four cultivation practices: polling, thinning, combination of polling and thinning and the control (neither thinning nor polling), have been applied on four selected varieties of cassava namely: Nsansi, Zizila, Butamu and a local one called Mbongo. The results obtained revealed that there is no significant differences between these techniques precisely on the tuber production of these varieties which are differently produced. These yields have been of 21.7 t/ha for Butamu; 28.6 t/ha for Nsansi; 20.2 t/ha for Zizila and 13.5 t/ha for Mbongo (the local variety). The overall results of this study show that polling and thinning combined techniques can be used for the improvement of the cassava productivity in Yangambi city.
