Research was conducted in Burkina Faso, Mali and Niger for determination of response functions for fertilizer nutrients. Trials had similar basic treatment structures for determination of response functions for N, P, and K, and a diagnostic treatment for resposne to Mg, S, Zn and B. Most treatments in Niger were intercroped with groundnut and had 2.5 Mg ha-1 yr-1 manure applied but had additional treatments for determination of the effect of manure and/or intercropping on yield and response. Treatments in Mali were sole crop sorghum, all with no manure applied. In Burkina Faso, all treatments were with sorghum sole crop with or without 5 Mg ha-1 manure applied in 2014 and evaluating the residual effect of manure in 2015.
