- Method / resource The VO/SAT corn model predicted silking date more accurately than CORNF, with a bias of 1 d.
- Intervention effect A 50% reduction in light reduced simulated corn yield by 26% relative to actual conditions.
- Intervention effect A 50% reduction in light reduced simulated corn kernel weight by 16% relative to actual conditions.
- Intervention effect A 50% reduction in light reduced simulated corn kernel number by 16% relative to actual conditions.
- Intervention effect A 50% reduction in light reduced simulated leaf area index by 20% relative to actual conditions.
- Intervention effect A 50% reduction in precipitation reduced simulated corn kernel weight by 51% relative to actual conditions.
- Intervention effect A 50% reduction in precipitation reduced simulated corn kernel number by 1% relative to actual conditions.
- Intervention effect A 50% reduction in precipitation reduced simulated leaf area index by 1% relative to actual conditions.
- Observation The combined corn model shows adequate sensitivity to light and water and could be modified to mimic weed competition.
