In Côte d'Ivoire, since 1980, coffee cultivation has experienced a decline in production due to drought, deforestation and the aging of the orchard. In order to revive this production, practices of replanting and regeneration by coppicing are adopted. The objective is to sustainably improve the production of coffee trees in order to generate added value. Specifically, it is a question of researching the effect of peasant practices on floristic diversity and determining coffee production according to these practices. A study on the effect of cultural practices on floristic diversity and coffee yield was carried out in Kéibla. The practices are: T0 (farmer practice), T1 (replanting + good agricultural practices without fertilization), T2 (replanting + good agricultural practices + fertilization) and T3 (replanting + good agricultural practices + fertilization). Following surface and itinerant surveys, the floristic diversity was determined. Quantitative dendrometric measurements allowed the structural-agronomic characterization. The results showed that the flora is rich with 66 species, 58 genera and 32 families. The analyzes showed that the T1 treatment recorded the best results with a density of 1259 plants/ha, a yield reaching 1041.07 kg/ha, a low mortality rate (23%) and a basal area of ​​33.70 m2. /Ha. In the T1 treatment, the species are diversified and better distributed. Taking peasant farming practices into account makes it possible to improve the production of coffee orchards.
