A study on reasoned mineral fertilisation has been carried out in the south-west of Côte d'Ivoire in order to ensure the sustainability of cocoa production. Specifically, the aim was to evaluate the effects of mineral fertilisers (PK) on soil fertility and cocoa production in Soubré, Méagui and Mayo. Thus, on each site, the experimental set-up was in Fisher block, with 4 replications for 4 treatments. The results showed that in terms of soil fertility, all the treatments favoured a good soil organic matter content (≥ 3%), a good pH (6.66-7.18), a good CEC (12 -1), an assimilable phosphorus content greater than 100 mg kg-1 and a ratio of (Ca/S) x100 ≥ 68%, which reflects a good balance between Ca and the sum of exchangeable bases (S). On the other hand, all the treatments had deficiencies in Potassium with (K/S) x100 < 8% and Magnesium with (Mg/S) x100 < 24. Finally, with the exception of the T2 treatment (NPK 0-15-15), the other treatments obtained a good balance between N and S, with (S+6.15) / N > (8.9). In terms of real yield, treatment T1 (NPK 0-23-19) had the best rate (1160.53 kgha-1), compared to T4 (NPK 0-18-9) and T2 (NPK 0-15-15) which had 951.92 and 730.59 kgha-1 respectively.
