Intervention effect Cover crops did not decrease corn grain yield at the AONR.
Intervention effect Cover crops did not increase the AONR compared with the no-cover crop treatment.
Observation In 2021, with near-normal precipitation, corn yield at the AONR and the AONR were the highest of the three years.
Observation In 2022, with about half the 30-year average rainfall, yield at the AONR decreased across treatments.
Intervention effect In 2023, cover crop treatments had no significant effect on the AONR.
