Gambiaj.com – (DAKAR, Senegal) – Senegal has emerged as a leader in high-quality onion production in Africa, thanks to groundbreaking research by the Center for the Development of Horticulture of the Senegalese Institute for Agricultural Research (ISRA/CDH). By applying innovative scientific methods and best practices, Senegal has achieved self-sufficiency in onion production. In contrast, The Gambia, despite progress in its own production, continues to face significant challenges, including bulb rot and onion collar diseases.

Recognizing the need to enhance its agricultural practices, The Gambia’s National Agricultural Research Institute (NARI) sought the expertise of ISRA to improve onion cultivation conditions and strengthen the skills of Gambian researchers. With support from the Food and Agriculture Organization (FAO), a delegation from NARI visited Senegal from March 16 to 21, 2025, to study Senegal’s successful strategies firsthand.

Key Learnings from Senegal

During the visit, Gambian researchers engaged in extensive discussions and field visits to understand the various aspects of onion cultivation, including the specific requirements of onion farming, good production practices, techniques for maximizing yield and quality, fertilization and irrigation techniques, crop maintenance, phytotechnics, disease management, and the cultural calendar for optimal production.

The delegation toured ISRA’s research stations in Cambérène and Sangalkam, as well as the National Laboratory for Research on Vegetable Productions (ISRA/LNRPV), to observe advanced research in action. These visits provided valuable insights into cutting-edge techniques for improving onion yield and combating common diseases affecting crops in The Gambia.

Adaptability to The Gambia

Beyond agricultural techniques, the delegation studied Senegal’s onion production ecosystem, particularly the organization of the Onion Interprofessional Group of Senegal (IPOS). This structure functions as a commercial platform that streamlines production and storage processes. The Gambian researchers were particularly impressed by the efficiency of this system and its potential applicability in The Gambia, where onion farming remains largely fragmented.

To conclude their mission, the Gambian delegation met with ISRA’s Director General, Dr. Moustapha Guèye, who emphasized Senegal’s commitment to knowledge-sharing and research collaboration. He highlighted the importance of strengthening ties between the two countries in agricultural development.

Dr. Ismaila Mbenga, Head of NARI’s Integrated Pest Management Directorate, described the tour as “an eye-opener that showcased the immense potential of research-backed agricultural development.” He emphasized that adopting Senegal’s best practices could significantly enhance The Gambia’s onion output. “Senegal, as a model of success in onion production, plays a crucial role in training and support in this sector. We have discovered varieties that we want to introduce in The Gambia,” said Ismaila Mbenga of NARI. He noted that the partnership with ISRA is essential for supporting The Gambia’s horticultural sector and ensuring sustainable agricultural growth.

The visit not only helped Gambian researchers gain practical knowledge but also laid the foundation for a stronger research and development partnership between the two West African nations.

By adopting proven Senegalese techniques, The Gambia aims to overcome its production hurdles and move towards self-sufficiency in onion farming. This collaboration underscores the importance of regional cooperation in advancing food security and agricultural sustainability in West Africa.
