Despite its cultivation in Côte d’Ivoire, the unavailability of edible mushrooms limits its promotion in human food. The objective of this study was therefore to find solutions to the productivity problems of the mushroom Pleurotus geesteranus on a mycicultural farm. To this end, a SWOT diagnostic study of the mushroom production system was carried out on the FESAAP farm in order to identify the causes of the lack of production and to provide solutions. This enabled corrective measures to be implemented. Production performance was then assessed. The SWOT diagnosis indicated a number of problems, including management, production knowledge, good farming practices... It also revealed strengths such as the proximity of the company to its customers and low production costs... The analysis of the external environment also showed opportunities such as a non-competitive local market and a diverse customer base... On the other hand, the lack of technical support, the absence of bank financing and the unavailability of inputs were mentioned as threats to the existence of this activity. The implementation of corrective actions such as the establishment of an operating organisation chart, the establishment of a relationship of trust between the staff and the executive office, etc., has enabled a substantial resumption of production with an efficiency level of 68.5%. However, efforts still need to be made regarding the yield per log, which for 600 g expected, only 190.3 g were obtained.
