In order to increase the quantity and quality of rice straw, experiments were conducted with six types of fertilizers with elemental sources (N-P-K-Ca-Mg-Zn) in Dabou, a locality located in the south of Côte d’Ivoire in the Grand Pont region. Examination of the results showed that fertilisers significantly improve the yield and straw quality of Nerica L 14 rice. However, better yields were obtained with nitrogen (1048.275 kg.ha-1) and phosphorus (810.55 kg.ha-1) as major elements while calcium and zinc as trace elements boosted yields to 763.65 kg.ha-1 and 810.25 kg.ha-1 respectively. As for the mineral content of the straw, only calcium and magnesium had a high influence.
