- Observation Moldboard plowing left 7 to 15% residue cover after planting.
- Observation No-till left 74 to 87% residue cover after planting.
- Intervention effect Soybean plants emerged slowest under no-till.
- Intervention effect Soybean plants emerged fastest under ridge-till.
- Intervention effect Tillage had no consistent soybean-yield effect, and differences were usually small.
- Intervention effect Early planting produced soybean yield equal to or above later planting, except once.
- Intervention effect Ten-inch rows yielded 8 to 14% more than 30-inch rows across tillage systems and planting dates.
- Observation Reduced tillage had less effect on soybean production than planting date or row spacing.
