Farmers in the Northern Region of Ghana are mostly smallholder farmers. They are continuously confronted with erratic rainfall and land degradation as a result of poor agronomic practices. Soil and Water Conservation (SWC) methods are interventions that can be put in place to limit soil loss and sustain soil moisture in areas where there is inadequate moisture and the risk of losing the valuable topsoil. In the 2014 cropping season, an on-farm experiment was conducted in the Region to assess the effect of SWC methods [Contour Farming (CF), Half Moon (HM), Contour Ridges (CR) and Flat Land (FL)] on soil moisture content at the root zone, growth components and yield of maize. There was a significant effect of the SWC methods on soil moisture at the root zone of maize at a probability (P) value of 0.00181. The CF retained the most soil moisture at the root zone with an average volumetric soil moisture of 18.4%. This was followed in decreasing order by CR (18.1%), HM (17.8%) and the FL (16.8%). The SWC methods significantly affected maize height (P = 0.0112), stem (P = 0.0174), root biomass (P = 0.035) and grain yield (P = 0.00578). Considering the higher soil moisture retention and yield under CF, it is recommended as the best option among the studied methods for SWC in Northern Region of Ghana.
