A. Olness; S. D. Evans; J. F. Moncrief Journal of Agronomy and Crop Science 1995. doi:10.1111/j.1439-037x.1995.tb01113.x
Other claims from this paper (9)
- Intervention effect With only starter fertilizer, maize grain yield increased with tillage intensity from NT through MP.
- Intervention effect With at least 55 kg total applied Nha −1, six-year average grain yields were unaffected by tillage.
- Observation Annual grain nitrogen removal with starter fertilizer ranged from 25–85 kg ha −1.
- Observation Maximum grain nitrogen removal was about 145 kg N ha −1 with 100–145 kg applied N ha −1 in favorable conditions.
- Association Several grain-yield interactions appeared sensitive to climate except tillage by fertilizer nitrogen interactions.
- Association Fertilizer nitrogen was associated with greater relative yield loss from planting delay than starter nitrogen only.
- Association MP tillage was associated with greater relative yield loss from planting delay than other tillages.
- Observation Yield loss from delayed planting ranged from 0.0–275 kg ha −1 day −1.
- Association Early spring soil temperatures gave MP tillage grain yield gains of 16.0–21.8 kg ha −1 index‐degree −1.
