Other claims from this paper (10)
- Intervention effect On alluvial soil, deep planting often gave the most uniform and timely emergence compared with shallow planting
- Intervention effect Shallow planting gave the least uniform emergence, especially on fine-textured soil under warm conditions
- Intervention effect Under the warm, fine-textured conditions, grain yield for one site-year was 2.8 Mg ha –1 less with shallow than with deep planting
- Intervention effect During warm conditions, deep planting enhanced emergence uniformity compared with shallow planting
- Intervention effect During warm conditions, deep planting enhanced emergence rate, reaching 90% emergence 1.1 days sooner than shallow planting
- Intervention effect Planting depth did not affect yield at any site-year of the landscape position study
- Association Stand establishment was affected by warm and cool growing conditions during emergence
- Recommendation The results suggest that certain soil textures and landscape positions require greater attention to planting depth for optimum stand establishment
- Observation Stands can often compensate for early establishment differences and maintain similar yield
- Recommendation Differences in emergence could be used in on-the-go planter prescriptions
