Faecal sludge recovery, an option that is increasingly being explored in the context of faecal sludge (BV) management. This study is part of this framework and tests the effect of BV scum compost, ash from BV incineration and NPK fertilizer (10-10-20), on cabbage. For the methodology, a Fischer block culture device was set up with 6 treatments (T0, T1, T2, T3, T4 and T5). These treatments are organised in 4 replicates, with three factors (dose of compost, compost plus ash and NPK fertiliser) in 24 elementary plots of 4 m2. The parameters for monitoring vegetative growth are: leaf height, number of leaves, crowding, diameter at the neck, nitrogen content. And the production parameters are: the average weight of the fruit, the diameter of the fruit and the yield. For cabbage, chemical fertilizer (2.61 t/ha) is better in terms of size, number of leaves and nitrogen content with 54.37 cm respectively; 19,12; 0.64. The best yield is obtained with the dose of chemical fertilizer at a rate of 31.59 t/ha. As fertilisers, BV scum compost alone and BV scum compost plus ash are beneficial for plants, but for crops such as cabbage, they cannot replace chemical fertiliser (NPK).
