Other claims from this paper (8)
- Intervention effect Later sowing dates increased final maize emergence.
- Observation Northern flint varieties had better final emergence than southern dent varieties.
- Observation Flint-by-dent hybrids had intermediate final emergence.
- Observation The lower final emergence of southern dent maize was most marked at early sowing dates.
- Observation Open-pollinated varieties usually emerged more slowly than flint-by-dent hybrids.
- Intervention effect Low-quality seed greatly reduced final emergence.
- Recommendation The authors recommended a standard cold test for maize seed in northwestern Europe.
- Recommendation The authors concluded that sowing before late April in Britain would give little advantage in emergence timing until low-temperature-tolerant varieties are available.
