Tree-crop interactions: recommendations for including trees in cropland


Date: 17/12/2013


J. Bayala, ICRAF-WCA, Mali and colleagues in West Africa carried out an experiment in Burkina Faso to characterise crop-tree interactions under a series of tree maintenance regimes. The treatment included root trenching and crown pruning of two tree species Parkia biglobosa and Vitellaria paradoxa, known to improve soil fertility and redistribute water, in a sorghum field. The results show that sorghum yield vary significantly depending on the treatment and the species used. An implication of this is that recommendations for including trees in cropland, or for management of existing trees within cropland, must be context and species specific.
