Highlights • Productivity of different intercropping patterns was tested in Guinea savanna of northern Ghana.• Land Equivalent Ratios in intercropping systems are greater under low soil fertility conditions.• Competitive balance between intercrops in poor fields leads to greater Land Equivalent Ratios.• Within-row maize-legume intercropping is more productive than distinct row systems.• Radiation use efficiency is higher in intercrops than in sole crops.
