Soil fertility depletion ranks as the most important drawback to crop productivity in Sub-Saharan Africa. On-farm experiments were conducted during the 2014/2015 and 2015/2016 seasons to explore the effect of nitrogen (N), phosphorus (P) and rhizobia inoculation on biological nitrogen fixation, yields, nutritional and mineral components of common bean in smallholder farming areas of Eastern Zimbabwe. Two improved common bean cultivars (Gloria and NUA45), widely grown in Zimbabwe were tested in a split-plot arranged in randomized complete block design.
