Other claims from this paper (18)
- Observation Control of eight major weeds reached at least 82% across planting systems.
- Intervention effect NR-HD soybean had 65% less weed biomass than MR-MD 10 weeks after planting.
- Intervention effect NR-HD soybean had 78% less weed biomass than WR-LD 10 weeks after planting.
- Intervention effect NR-HD soybean yielded 8% more than MR-MD.
- Intervention effect NR-HD soybean yielded 27% more than WR-LD.
- Intervention effect Net returns were similar for NR-HD and MR-MD.
- Intervention effect Net returns for NR-HD and MR-MD exceeded WR-LD.
- Observation Control of weed species other than yellow nutsedge was at least 90% across herbicide programs.
- Observation Yellow nutsedge control ranged from 85% to 91% among herbicide programs.
- Intervention effect PRE + POST reduced weed biomass relative to PRE alone.
- Intervention effect PRE + POST reduced weed biomass relative to POST alone.
- Intervention effect PRE + POST produced higher soybean yield than single-timing herbicide programs.
- Intervention effect PRE alone reduced soybean yield by 9% to 10% relative to PRE + POST.
- Intervention effect POST alone reduced soybean yield by 9% to 10% relative to PRE + POST.
- Intervention effect PRE + POST had lower net returns than PRE only.
- Intervention effect PRE + POST had lower net returns than POST only.
- Intervention effect CT and NT had similar weed control and weed biomass.
- Mechanism Improved weed control partly explained the NR-HD yield advantage.
