Abstract:

Cassava (Manihot esculenta Crantz) is an important food crop in Democratic Republic of the Congo. It is a tuberous crop that produces long and tapered storage roots that are a major source of energy and carbohydrates. Depending on the cultivars and growing conditions, these large storage roots are harvested 6 to 24 months after planting. The present study was conducted under agro-ecological conditions of Gbadolite city during 12 months in order to evaluate the effect of cassava sample cuttings area on the yields of tuber roots. The results revealed that the yields were 15.33; 16.40 and 15.60 t/ha for the base cuttings, middle and top cuttings respectively. This indicates that the sampling area does not affect cassava tuber roots production (p>0.05), and means that all the cassava stems can be used as propagating material in the District of Nord Ubangi. For the best of our knowledge, this is the first time report on such research in the District of Nord Ubangi.
