AB Farming systems in the semi-arid Bugesera region of Rwanda combine crops and trees in an agroforestry-based intercropping system, with Grevillea robusta being a common tree species. The integration of trees on smallholder farmers’ fields has been reported to result in competition for resources. Pruning at 75% was used to manage the competition between G. robusta and maize. This study aimed to investigate the effect of pruning on water uptake in G. robusta and productivity of associated maize.
