Eggplant is the third most cultivated member of the Solanaceae family after tomato and potato. It is widely consumed in Nigeria, particularly Southern Nigeria, for its nutritious, medicinal fruit, leaves and seeds. The crop plays a significant role in improving socioeconomic lives. The choice and use of eggplants by the indigenous people are need-based and driven by cultures and specific characteristics of the plant. This study aims to delineate indigenous knowledge in Southern Nigeria for the continued use and conservation of eggplants. The study shows that the variation in indigenous knowledge is attributed to the preferences of locals and the significance of the crop. The outcome of this study may enhance the sustainable utilisation and conservation of eggplant.
