Fertiliser microdosing (FM) is widely promoted in sub‐Saharan Africa as a means to improve fertiliser use efficiency in cereal crops. However, combining organic amendments with FM could further increase the agronomic efficiency of the latter because of possible synergies between both practices. This study therefore evaluated whether combining FM with organic amendments enhanced fertiliser use...
Abstract: Fertilizer microdosing (FM) is being promoted in sub‐Saharan Africa (SSA) to boost crop productivity on smallholder farms. However, yield response variability is a barrier to adoption. We conducted a meta‐analysis to analyze the variability in cereal crop yield response to FM and to determine the main factors associated with this variability. Thirty publications pertaining to millet...
