Other claims from this paper (7)
- Intervention effect Only plant emergence variability significantly affected corn plant height, leaf area index and dry matter accumulation.
- Intervention effect Compared with uniformly early emerged plants, one in six plants with a four-leaf stage delay in emergence reduced corn yield by 8%.
- Observation Corn plants next to a gap demonstrated compensatory growth.
- Observation Corn plants adjacent to a late emerging corn plant did not exhibit compensatory growth.
- Intervention effect Variation in within-row spacing did not affect corn yield.
- Intervention effect Interactions between plant spacing variability and emergence variability were not significant for corn yield.
- Intervention effect Corn is more responsive to plant emergence variability than to plant spacing variability.
