The technologies under investigation is an integration of soil fertility and soil and water conservation practices (Table 1). Soil fertility inputs include mineral fertilizer and animal manure at different rate, while soil and water conservation practices include tied ridges, minimum tillage with crop residue, and Managing Beneficial Interactions in Legume Intercrops (MBILI).
