Other claims from this paper (6)
- Intervention effect Emergence variability significantly affected corn height, leaf area index, dry matter accumulation, and grain yield.
- Intervention effect A two-leaf emergence delay for one of six plants reduced corn yield by 4% relative to uniform early emergence.
- Observation Corn adjacent to a gap showed compensatory growth.
- Observation Corn beside a late-emerging plant showed no compensatory growth.
- Intervention effect Within-row spacing variation did not affect corn yield.
- Association The interaction between emergence and spacing variability was not significant.
