Analysis of wheat yield gaps in Ethiopia

Wheat field
Copyright Silva et al.

In Ethiopia, wheat yields must increase substantially to accommodate population and dietary changes. Scientists Vasco Silva et al. measured the influence of water, suboptimal inputs, crop management, and technology on yield gaps. They attributed 50% of the yield gap to a lack of technology. They estimated, however, that if more inputs were added and used more efficiently, fine-tuning current management practices could double yields and achieve wheat self-sufficiency without increasing crop area.
