Other claims from this paper (7)
- Intervention effect Delaying first irrigation restricted corn root growth in some cases and had no influence in others.
- Intervention effect Delaying first irrigation increased corn water use during anthesis, especially at 2 to 3 feet depth.
- Intervention effect Delaying first irrigation delayed corn silking by approximately 3 days.
- Intervention effect Delaying first irrigation decreased corn dry matter accumulation rate.
- Intervention effect In 1990, delaying first irrigation past the 2 leaf stage reduced corn grain yield by 20% when irrigated at anthesis.
- Intervention effect In 1990, delaying first irrigation past the 2 leaf stage reduced total corn plant yield by 14% when irrigated at anthesis.
- Intervention effect First irrigation timing did not affect corn yield when irrigation was withheld at anthesis.
