Other claims from this paper (10)
- Observation A within-year yield range above 25% occurred in one-fourth of seasons for continuous corn.
- Observation A within-year yield range above 25% occurred in one-fourth of seasons for continuous soybean.
- Observation Ten-year average yield ranges among continuous soybean plots were below 10%.
- Observation Five of six plot-yield comparisons showed no significant difference.
- Observation Across locations, corn yield range averaged at least 20 bu/acre.
- Observation Across locations, soybean yield range averaged at least 6 bu/acre.
- Observation Between-year soybean yield variability was about three times between-plot variability.
- Observation Between-year corn yield variability was about four times between-plot variability.
- Observation Corn-soybean rotation plots showed similar yield variability.
- Recommendation Producers should wait for persistent yield differences before changing management for small low-yielding areas.
