Maize Yield Growth Lagging Behind Food Security Demand

In recent years, the annual growth in maize yield has been limited to approximately 1.6% globally and less than 2.0% in China. This falls short of the increased demand of 2.4% required to ensure food security by the mid-century. (Shiferaw et al., 2011; Tilman et al., 2011; van Dijk et al., 2021)
