Fertilizer Microdosing and “Warrantage” or Inventory Credit System to Improve Food Security and Farmers’ Income in West Africa

摘要: The fertilizer microdosing technology deals with the application of small quantities fertilizers in planting hole, thereby increasing use efficiency and yields while minimizing input costs. In drought years, also performs well, because larger root systems are more efficient at finding water, it hastens crop maturity, avoiding late-season drought. Recent research found that solving soil fertility problem unleashes yield potential improved millet varieties, generating an additional grain nearly same quantity. Recognizing liquidity constraints often prevent farmers from intensifying their production system, warrantage or inventory credit system helps to remove barriers adoption restoration. Using a participatory approach through network partners National Agricultural Research Extension Systems (NARES), non-governmental organizations (NGOs), farmer groups other international agricultural centres, have been demonstrated promoted Burkina Faso, Mali, Niger during past few years encouraging results. Sorghum increased by up 120%, farmers’ incomes went 130% when was combined system. This chapter highlights outstanding results ongoing efforts further scale using Farmer field schools (FFS) demonstrations, capacity institutional strengthening, private sector linkages diversification amongst approaches.
