Abstract
This paper analyzes the impact of integrated soil fertility management (ISFM) on maize yield, yield gap and net income in northern Ghana using an inverse-probability-weighted regression adjustment (IPWRA). In this study, ISFM is restricted to the adoption of crop rotation (CR), inorganic fertilizer (FT), and farmyard manure (MN) either in isolation or in combination. We find a synergy in yield gain (86.52% increase in yield) and a decrease in yield gap (of 10.22%) with the adoption of all three technologies as a package (CR+FT+MN). The joint adoption of all three technologies is also associated with a 51.29% increase in net income from maize production and has a Benefit-Cost Ratio of 3.23.
