ABSTRACT: The search for a solution to the decline in cocoa bean yields in Côte d’Ivoire remains a preoccupation. This study was carried out to evaluate the combined effects of the mineral fertilizer NPK 0-23-19 + TE and the liquid fertilizer NPK 11-9-41 on cocoa yield parameters in the locality of Divo, specifically in the villages of Troucasso and Gazaville. The experimental set-up was a Fisher block design, with 4 replications for 11 treatments. Results showed that treatments receiving mineral fertilizer combined with liquid fertilizer improved cocoa yields. Treatments T4 (300 g NPK 0-23-19 + TE + 0.045 L NPK 11-9-41) and T5 (300 g NPK 0-23-19 + TE + 0.09 L NPK 11-9-41) were more effective at Troucasso. They had actual yields of 1627.36 kg∙ha−1 and 1836.61 kg∙ha−1 respectively, and potential yields of 1886.62 kg∙ha−1 and 2032.08 kg∙ha−1. In Gazaville, on the other hand, treatments T4 (1788.68 kg∙ha−1), T5 (1923.25 kg∙ha−1) and T9 (150 g NPK 0-23-19 + TE + 0.18 L NPK 11-9-41) with 1642.41 kg∙ha−1 had the best actual yields. The same applies to potential yield, with these treatments achieving 1920.37 kg∙ha−1, 2141.21 kg∙ha−1 and 1829.14 kg∙ha−1 respectively. As for wilted cherelles, treatments T4, T5 and T9 had the highest values on both experimental sites.
