Résumé
Due to high demand for food resources as a result of increasing population, the promotion of large-scale crops such as wheat has become essential. Unfortunately, soil infertility and a lack of improved seed are major constraints on the expansion of this crop in Kaziba, a mountainous rural area in South Kivu. The productivity of seven wheat varieties (Farari, Kayira, Kima, Lokale, Mbega, Nyumbu and Popo) was evaluated under organic and mineral fertilizer during the 2013-2014 crop season on poor soil in South Kivu (DR Congo). NPK 17-17-17, farmyard manure and their combination were applied as fertilizers in a split-plot trial design with three replications. The observations focused on the growth and yield parameters, and the results revealed differences between varieties, treatments and interactions. The NPK + farmyard manure treatment gave the highest mean yield (1317.2 kg), Kayira was the most productive variety (1584.2 kg), and the interaction Kayira X farmyard manure was the most effective (2874.9 kg). The variety Kayira would seem to be indicated, with farmyard manure as the recommended fertilizer, being locally accessible and easily usable for promoting wheat in the region.
