Using an integrated genetic and natural resource management (IGNRM) approach, this project aims at enhancing adaptation of pearl millet [Pennisetum glaucum (L.) R. Br.] and sorghum [Sorghum bicolor (L.) Moench] to low-phosphorus (P) soils and water stress in the Sahelian zone of West Africa (WA). A combination of physiological experiments, classical and marker-assisted breeding research, and agronomic studies is used to tackle the combined effects of low soil P and droughts on pearl millet and sorghum growth in West Africa’s smallholder cereal production systems. In a step-wise approach the studies will unravel available genetic diversity for low-P tolerance and enhance the understanding of the relative importance of low soil P and water stress, and their interaction, for cereal productivity in the Sahel. New crop management techniques beyond fertilizer micro-dosing will be developed and tested, such as seed coating with P, promotion of symbiosis with vesicular-arbuscular mycorrhiza (VAM) and on-farm processing of rock phosphate (RP), to help enhancing productivity under Sahelian abiotic stress conditions. A strong focus on farmer experimentation with adapted cereal cultivars and new crop management options will help validating these techniques and contribute to early adoption and project impact.
