Effect of farmland trees Terminalia brownie and Vitex doniana on soil physicochemical properties and maize yield

This study was focused on evaluating maize yield and soil fertility improvement under the canopy of retained farmland tree species, particularly Terminalia brownie Vitex doniana in parkland Agroforestry. The area suitable for cropping mature species exist area. result showed that Maize decreased understory studied tee compared with open field due to shading effect crop performance. On other hand, parameters near trunk/under cover terms pH level, total nitrogen, phosphorus, organic carbon obtained except available potassium. trees supply quantified amounts important nutrients through addition biomass modifying microclimate ease decomposition, so resource poor farmers had shortage replenishing soils mineral fertilizer application. present concluded multipurpose agroforestry have potential improved farming system these could be promoted smallholder farms by using appropriate above ground management options.
