- Observation Eyespot and lodging were prevalent in 1946.
- Observation Weeds were prevalent in the second year.
- Observation Eyespot, lodging, take-all and weeds occurred in the third year.
- Intervention effect Acid spraying reduced eyespot, lodging and weeds.
- Intervention effect Acid spraying raised grain yield on ammonium sulfate plots by 2.2 cwt./acre in the second year.
- Intervention effect Acid spraying raised grain yield on ammonium sulfate plots by 10.0 cwt./acre in the third year.
- Intervention effect Ammonium sulfate increased eyespot at harvest.
- Intervention effect Ammonium sulfate increased lodging at harvest.
- Intervention effect Ammonium sulfate reduced take-all.
- Intervention effect Ammonium sulfate consistently increased straw yield.
- Association Eyespot and lodging reduced the fertilizer effect on grain yield.
- Association Take-all increased the fertilizer effect on grain yield.
- Intervention effect Higher seed rate increased severe eyespot and take-all.
- Intervention effect Higher seed rate increased lodging unless take-all dwarfed the plants.
- Association Straw weight and severe eyespot jointly explained 51% of lodging variance at harvest.
- Association Straw weight and severe eyespot jointly explained 64% of earlier lodging variance.
- Observation Untreated grain yields declined across successive years.
- Observation Treated plots maintained grain yields across successive years.
- Association Spraying boosted grain similarly to a year of fallow, with larger benefits at high nitrogen.
