Other claims from this paper (13)
- Intervention effect Narrow rows improved corn emergence by 12% compared with wider rows.
- Intervention effect Narrow rows improved corn yield by 15% compared with wider rows.
- Intervention effect Higher population density increased grain yield by up to 28% in site years with normal to high precipitation.
- Intervention effect Seeding rate had no significant effect on grain yield under low precipitation.
- Observation Nitrogen fertilization rate and application timing had marginal effects on corn yield.
- Intervention effect Fertilizer rates above 113 kg N ha −1 reduced seedling emergence and development.
- Intervention effect Fertilizer rates above 113 kg N ha −1 reduced grain yield by up to 6%.
- Intervention effect Zero tillage reduced plant establishment by up to 25%.
- Intervention effect Earlier seeding did not affect grain filling or yield.
- Observation The late maturing variety was 10 cm taller.
- Observation The late maturing corn variety took 6 days longer to reach tassel and silking.
- Observation The late variety traits had no impact on grain yield.
- Recommendation The authors indicate that seeding above 60 000 seeds ha −1 with 113 to 169 kg N ha −1 fertilization can produce yields above 4.24 Mg ha −1.
