Other claims from this paper (8)
- Intervention effect Seeding rate did not affect cereal rye biomass or corn growth and development.
- Intervention effect Broadcast cereal rye produced about 3.5 times more biomass than drilled cereal rye under three locations in Iowa.
- Intervention effect Broadcast cereal rye reduced corn yield by 7.2% compared with drilled cereal rye under three locations in Iowa.
- Intervention effect Late termination (3 days before planting) produced 2.1 times more cereal rye biomass than early termination (14 days before planting).
- Intervention effect Late termination of cereal rye reduced corn yield by 4.1% compared with early termination.
- Intervention effect Broadcast cereal rye was associated with greater corn root rot incidence than drilled cereal rye, and Pythium spp. are pathogens that increase with cover crops.
- Intervention effect Late termination of cereal rye greater radicle rot incidence in corn in one year.
- Recommendation Farmers should be careful using broadcast seeding and late termination of the cereal rye cover crop before planting corn.
