Filter cake is a by-product commonly used as organic fertilizer in sugarcane on plant crop for the whole plantation cycle. The study was carried out over three cropping seasons (2014-2016) on Borotou sugarcane plantations in northwestern Côte d’Ivoire, following a split-plot design involving 9 treatments and 4 replicates. Filter cake, as main factor involved 3 application rates (0 t/ha, 15 t/ha and 30 t/ha), whereas NPK mineral fertilizer stood as sub-factor with 3 application rates (0 kg/ha, 350, kg/ha and 700 kg/ha). The objective of experiment was to determine the effect of filter cake and mineral NPK fertilizer on soil cation exchange capacity and sugarcane yields. It came out that soil CEC, sum of bases (S) and base saturation ratio (V) were significantly improved with increasing rates of filter cake. Although cane and sugar yields obtained increased slightly with fertilizer rates, differences observed on each yield variable were not significant.
