ABSTRACT
The population of the world is projected to reach 9.7 billion by 2050 from the current 7.3 billion. Most of this increase is expected to occur in the developing world (UN, 2015) and this requires increase in food production (FAO, 2014). Sustainable intensification is crucial in areas of high population densities where land expansion is limited (Pretty et al., 2011; Vanlauwe et al., 2014; Cook et al., 2015). Integration of grain legumes in farming systems in the context of integrated soil fertility management offers a potential pathway for sustainable intensification as they are vital for improving soil fertility.
