ABSTRACT: Grapes are the main reason why the grapevine (Vitis vinifera L.) is cultivated. However, climate, soil conditions, vegetation and anthropogenic effects on the soil greatly affect grapevine production. The organoleptic properties of grape-derived products, such as wine, are influenced by these factors, which are becoming increasingly popular in Africa. Thus, grapevines, which are commonly grown in warm regions, are acclimatized in Africa using grapevine varieties that can adjust to tropical conditions. This study, which was carried out in 2019, aimed to promote grapevine cultivation in Côte d’Ivoire by examining the influence of pedoclimatic factors on the agro-physiological characteristics of grapevines. In Côte d’Ivoire, there were four distinct agro-ecological zones (North, South, Southeast and West) where three grapevine varieties, Bequignol, Muscat Rouge and Aleatico, were grown. Grapevine plants could grow robustly in morpho-physiological ways because the soils had sufficient fertility, as revealed by the analysis of experimental sites. Grapevine varieties have successfully adapted to different terroirs, with the exception of Muscat Rouge, which only displayed favorable morphological characteristics in the Man zone (West). Regardless of the grape variety, the regions with the best grapevine-growing conditions were Man (West), followed by Aboisso (Southeast). Consequently, grapevine development was less favorable in Korhogo (North) and Abidjan (South) zones. Thus, the cultivation of grapevine varieties in Côte d’Ivoire was greatly influenced by terroir.
