Other claims from this paper (9)
- Association A simulated increase in maximum temperature had a negative impact on potential and rain-fed potential maize yield.
- Association A simulated increase in minimum temperature produced no significant change in potential or rain-fed potential maize yield.
- Association The increase in minimum temperature had a positive impact on on-farm maize yield.
- Observation Farmers adopted longer season maize hybrids.
- Association The gap between potential and rain-fed potential yields is larger at locations with lower seasonal precipitation (<500 mm).
- Observation The largest yield gaps between rain-fed potential and on-farm maize yields are in the southeast of NEC.
- Observation On-farm maize yields in NEC averaged only 51% of potential yields.
- Recommendation Effective irrigation, fertilization, herbicide use and planting density are suggested to raise maize production in NEC.
- Observation Maize growing seasons in NEC show a warming trend from 1981 to 2010.
