Other claims from this paper (7)
- Observation Cover crop biomass ranged from 430 to 3,440 kg ha −1 across sites, with cereal rye generally producing the most consistent high biomass.
- Intervention effect All cover crops reduced rice emergence by up to 30% in one site-year.
- Intervention effect Cereal rye reduced rice groundcover by 13% in one site-year two weeks before heading.
- Intervention effect Cereal rye reduced Palmer amaranth emergence by 19% relative to no cover crop for April planted rice at Marianna.
- Intervention effect Cereal rye reduced Palmer amaranth emergence by 35% relative to no cover crop for May planted rice at Fayetteville.
- Intervention effect In most trials a cereal cover crop did not reduce Palmer amaranth emergence.
- Intervention effect Legume cover crops generally produced less Palmer amaranth emergence than no cover crop.
