Can you plant cabbage and corn together?

It depends. The sources disagree about cabbage and corn. A field trial found no clear difference to competition for light and water, while a shared bed gave about 15% more harvest than separate beds in one field trial.

Sweet corn gains more. Partial LER is each crop's share of the yield it would give alone.

1 field trial. Published LERs lean high.

Harvest from the same space compares a bed with both crops against the same area split into single-crop beds, counting the harvest of both crops (the land equivalent ratio in yield trials).
