Other claims from this paper (9)
- Intervention effect Compaction impaired agronomic traits of soybean cultivars.
- Observation The medium-cycle soybean cultivar performed better under compaction.
- Intervention effect Stomatal conductance fell by up to 50% under compaction.
- Intervention effect Transpiration rates fell by up to 50% under compaction.
- Observation The three gas-exchange traits were not influenced by cultivar.
- Intervention effect Lower-maturity soybean cultivars had lower plant height, shoot and root dry mass, pod number, and grain yield under compaction.
- Intervention effect Lower-maturity soybean cultivars had fewer pods under compaction.
- Intervention effect Lower-maturity soybean cultivars had lower grain yield under compaction.
- Recommendation The authors suggest choosing longer-cycle soybean cultivars to reduce compaction damage.
