Pourquoi le ma\u00efs hybride est important<\/span>\u00a0<\/span><\/h3>\nEn Afrique, le ma\u00efs est plus qu'une simple culture. C'est un aliment de base pour des millions de m\u00e9nages et reste central pour la s\u00e9curit\u00e9 alimentaire, les moyens de subsistance et la stabilit\u00e9 \u00e9conomique sur tout le continent. Alors que l'Afrique de l'Ouest est l'une des plus grandes r\u00e9gions productrices de ma\u00efs du continent, avec des pays comme le Nigeria produisant plus de 10 millions de tonnes m\u00e9triques par an, les rendements par hectare restent relativement faibles en raison de la d\u00e9pendance continue vis-\u00e0-vis des vari\u00e9t\u00e9s \u00e0 pollinisation libre (VPL).\u00a0<\/span>\n\nLire la suite<\/a>","protected":false},"excerpt":{"rendered":"
