e0“Over the 4-wk harvesting period, the DM content of the grain increased, on average, at a rate of 4% per week whereas the DM content of the stover increased by about 1% per week; shoot DM content increased at 2% per week.”

Other claims from this paper (16)
- Intervention effect Early planting increased leaf area per plant in mid-July.
- Intervention effect Early planting produced shorter plants at maturity.
- Intervention effect Early planting yielded smaller maximum leaf areas.
- Intervention effect Early planting changed dry matter (DM) yields of shoots by 1.0.
- Intervention effect Early planting changed grain by 1.9 t/ha.
- Intervention effect Early planting changed stover (stem + leaf + husk) DM yield by 0.9 t/ha.
- Observation The hybrid with the highest grain yield and grain DM share had lower shoot DM yield than a lower grain-yielding hybrid.
- Observation Shoot DM yields did not increase with later harvest.
- Observation grain DM yield increased with later harvest.
- Observation proportion of shoot DM as grain increased with later harvest.
- Observation DM content of the stover increased by 1% per week during harvest.
- Observation shoot DM content increased by 2% per week during harvest.
- Association Shoot DM content rose linearly with heat units accumulated since silking, requiring 41 CHU per 1% gain.
- Observation The hybrids formed two pairs with significantly different y-intercepts.
- Recommendation The authors suggested exploiting genetic differences in heat-unit requirements to improve forage maize productivity without lowering dry matter content.
- Recommendation The authors emphasized appropriate hybrid maturity and full use of the growing season for high-quality forage.
