Effects of Organic and Mineral Fertilization, and Mycorrhizal Inoculation on the Growth and Agronomic Performance of Two Taro (Colocasia esculenta (L.) Schott) Varieties in Bamendjou, Western Highlands of Cameroon

Abstract Taro (Colocasia esculenta (L.) Schott) is an essential tuber crop contributing to food security and rural livelihoods in tropical regions, particularly in the Western Highlands of Cameroon. However, declining soil fertility severely restricts its agricultural productivity. This study evaluated the individual and synergistic effects of organic fertilization, mineral fertilization, and arbuscular mycorrhizal fungal (AMF)

Seasonal and habitat-dependent variation in the survival time of antelope, buffalo, and gorilla dung in the Congo Basin Rainforest of South-East Cameroon

Abstract: Dung-based surveys are widely used to estimate the abundance and population density of elusive forest mammals. The accuracy of these survey depends on reliable estimates of dung density, defaecation rate, and dung survival (decay) time, which may vary with season and habitat. This study evaluated the survival time of dung from antelopes, buffaloes, and

Non-linear soil health trajectories in smectitic Vertisols : Coupling sedimentary inheritance to long-term intensive cultivation in Am-Timan, South eastern Chad

Abstract: Long-term cultivation can substantially reorganize soil physicochemical functioning in semi-arid agroecosystems, particularly in smectitic Vertisols developed from fine-grained alluvial deposits. This study assessed depth-dependent soil quality trajectories and the influence of sedimentary inheritance along a cultivation chronosequence in Southeastern Chad, comprising an uncultivated reference and fields cultivated for approximately 25, 35, and 50 years

Soja : utiliser les ressources génétiques locales pour améliorer la productivité

Des chercheurs de l’IRAD valorisent les accessions locales (Glycine max) afin d’obtenir des variétés performantes, résilientes et adaptées aux conditions agroécologiques de l’Adamaoua.  La productivité du soja reste faible, malgré son importance économique et nutritionnelle, en raison de contraintes telles que le manque de variétés adaptées, la dégradation des sols, le stress hydrique et l’accès

La farine de banane plantain pour réduire la dépendance au blé

Un projet implémenté par des chercheurs de l’IRAD dans le Littoral et le Sud-Ouest mise sur la valorisation des technologies post-récolte pour augmenter la part de farine locale en boulangerie. L’un des objectifs du Plan intégré d’import-substitution agropastoral et halieutique (PIISAH) est d’atteindre un quota de 15% de farine locale dans la production des produits
