Smallholder farmers widely use nitrogen, phosphorus and potassium fertilizers for maize production in northern Ghana and Benin. Using those fertilizers, the yield increases appears to have plateaued, making it necessary to reevaluate other soil nutrients for their potential to boost crop yield. This poster presents the evaluation of  Zn and B on maize grain yield in atypical open parkland systems dominated by shea trees.
