📕 This book is made up of seven chapters following the introductory chapter. The chapter two reviewed the main developments in soil fertility management for increased yields in low-input millet-based cropping systems in Sahelian areas. Chapter three discusses the determinants of fertilizer micro-dosing induced yield increment of pearl millet. Chapter four addresses the potential of combined application of fertilizer micro-dosing and manure to improve millet yield and water use efficiency. Chapter five deals with the nutrient balances under fertilizer micro-dosing while the potential of Acacia tumida mulches for increasing millet yield and water use efficiency under fertilizer micro-dosing is presented in Chapter six. Chapter seven provides the general discussion of the main findings described in the different sections of Chapter four and finally Chapter eight provides the conclusions and recommendations emanating from the study.
