Other claims from this paper (6)
- Observation Corn and medic intercrops in 1992 had land equivalent ratios no greater than one.
- Intervention effect Medics at 260 seeds m− 2 reduced weed dry weight by 41% at Rosemount relative to corn monoculture.
- Intervention effect This seeding rate reduced weed free corn grain yield by 21% at Becker versus monoculture.
- Intervention effect This seeding rate reduced weed free corn grain yield by 15% at Rosemount versus monoculture.
- Intervention effect Medic smother plants reduced weed dry weight more at zero nitrogen than at 168 kg ha− 1 nitrogen.
- Intervention effect Corn yield losses were less severe with 168 kg ha− 1 nitrogen than with zero nitrogen.
