Other claims from this paper (7)
- Association Dense corn population was associated with a 26.2% loss in pigweed leaf area index (LAI).
- Association Dense corn population was associated with a 16% loss in pigweed total dry matter accumulation (TDM).
- Intervention effect Zigzag twin row corn reduced pigweed LAI by 7.9% more than rectangular twin row at the highest pigweed density.
- Intervention effect Zigzag twin row corn reduced pigweed TDM by 4.1% more than rectangular twin row at the highest pigweed density.
- Intervention effect Zigzag twin row corn reduced pigweed WGR by 6.1% more than rectangular twin row at the highest pigweed density.
- Association The effect of corn planting pattern on pigweed growth indices was lower than the effect of corn density.
- Recommendation The authors recommend extending twin row patterns with increased corn density to suppress pigweed growth without chemical herbicide.
