Other claims from this paper (5)
- Intervention effect Hairy vetch living mulch in the no-treatment control or dead mulch in the mowed treatment improved weed control during the first 6 wk of the season in no-tillage corn.
- Intervention effect Weed control deteriorated after the first 6 wk in the hairy vetch living mulch and dead mulch treatments in no-tillage corn.
- Intervention effect Competition from weeds and uncontrolled vetch in treatments without herbicides reduced corn yield in three of four years by an average of 46% compared with a standard PRE herbicide treatment.
- Intervention effect Reducing atrazine and metolachlor to one-fourth the rate in the absence of cover crop reduced weed control in three of four years compared with the standard treatment.
- Intervention effect Hairy vetch had little influence on weed control or corn yield under any herbicide treatment.
