• Cereal-legume intercrops overlay doubled-up legumes in biological nitrogen fixation (BNF), water use efficiency (WUE) and crop productivity: A meta-analysis (2026) · African Journal of Agricultural Research · doi

  Further research is needed to investigate the effects of other factors such as pest and disease management on BNF, WUE, and yield. Further research is needed to investigate the potential of cereal-legume intercropping to increase crop productivity in other regions. Further research is needed to develop more efficient and effective cereal-legume intercropping systems.

• Yield and quality of maize crop under mono- and binary cropping (2026) · Bioenergy · doi

  The study identifies a gap in knowledge on the effect of fertiliser systems on the yield and quality of maize and soybean under mono- and binary cropping. The research aims to fill this gap by examining the productivity and nutrient content of maize and soybean under different fertiliser systems.
