Citrus is a magnificent crop fruit globally known for its nutritional, industrial and medical properties. The crop is characterized by an abundant yield and is then a consistent cash provider around the world. Unfortunately, the crop fruit has been facing increasing biotic, abiotic and technical constraints in Benin Republic. Citrus production is in jeopardy in the country. This situation may turn into a nightmare if no actions are undertaken to mitigate those constraints. This paper provides an overview of the past and current research and knowledge linked to citrus production in the Benin Republic in order to point out gaps that should be filling-up for its sustainable production. It also intends to stimulate future research activities for better citrus production.
