Other claims from this paper (14)
- Intervention effect Phosphorous, complete fertilizer, and manure plots produced higher corn yield than the check.
- Intervention effect Those corn fertilizer and manure plots had more marketable grain.
- Intervention effect Corn shelling percentage varied little among plots but was somewhat lower with nitrogen and floats.
- Intervention effect Nitrogen-phosphorous yielded the highest pounds of shelled corn per pound of stover.
- Intervention effect Complete fertilizer produced a high grain-to-stover percentage in corn.
- Intervention effect Nitrogen-phosphorous and manure plots increased corn mature-ear percentage.
- Intervention effect Corn developed earlier with manure and later on the check plot.
- Intervention effect Manured corn plants had greater circumference and height.
- Intervention effect Corn-character means were greater on fertilized than check plots.
- Association Corn-character means increased with productivity.
- Intervention effect Variation constants were generally greater on fertilized corn plots than checks.
- Intervention effect Corn-character correlations were generally greater on fertilized plots, without significant odds.
- Observation Wheat showed opposite, generally nonsignificant results.
- Association High corn yield was associated with favorable grain and maturity traits.
