Other claims from this paper (9)
- Intervention effect Irrigation and tillage significantly affected grain and silage yield each year except grain in 1986.
- Intervention effect Mean four year dryland grain yield was 4.45 Mg ha −1.
- Intervention effect Mean four year grain yield with limited irrigation was 8.00 Mg ha −1.
- Intervention effect Mean four year grain yield with full irrigation was 10.77 Mg ha −1.
- Intervention effect Mean four year grain yield under no tillage was 8.01 Mg ha −1.
- Intervention effect Grain water use efficiency was similar under both tillage treatments at 217 kg ha −1 cm −1.
- Intervention effect Silage water use efficiency under conventional tillage was 277 kg ha −1 cm −1.
- Intervention effect Silage water use efficiency under no tillage was 381 kg ha −1 cm −1.
- Recommendation The authors conclude irrigation has potential in Piedmont areas with limited water supplies alongside no tillage.
