J. A. Stecker; D. D. Buchholz; P. W. Tracy jpa 1995. doi:10.2134/jpa1995.0061
Other claims from this paper (14)
- Observation Corn grain yields exceeded 175 bu/acre at 29 of 47 site-years.
- Intervention effect Sulfur fertilizer increased grain yield at three of 47 harvested sites.
- Intervention effect Sulfur fertilizer decreased grain yield at five sites.
- Observation Leaf sulfur concentrations were above prior critical levels.
- Intervention effect Fertilizer sulfur increased leaf sulfur concentrations at 36% of sites at six-leaf stage.
- Intervention effect Fertilizer sulfur increased leaf sulfur concentrations at 38% of sites at anthesis.
- Intervention effect Fertilizer sulfur increased grain sulfur concentrations at 15% of sites.
- Association Leaf sulfur concentration correlated poorly with relative yield.
- Association Grain sulfur concentration correlated poorly with relative yield.
- Association Tissue nitrogen-to-sulfur ratios correlated poorly with relative yield.
- Method / resource Soil sulfate recommendations were wrong at only three sites.
- Intervention effect Fertilizer sulfur did not affect grain crude protein.
- Association No tested site factor was linked to yield loss without sulfur fertilizer.
- Recommendation The authors recommend against routine sulfur fertilizer for Missouri corn on medium to fine soils.
