Other claims from this paper (5)
- Observation On-farm maize yield gains slowed to 54 kg ha⁻¹ y⁻¹ since 2000 versus 135 kg ha⁻¹ y -1 in 1970–1999.
- Observation Modeled yield potential declined by -142 kg ha −1 y -1 since 2001 because of warming.
- Mechanism Agronomic and genetic adaptation offset negative climate impacts on maize yield.
- Observation Average farmer yield was 32% below estimated yield potential.
- Recommendation Further maize yield gains are possible through improved agronomic management.
