- Observation dry matter production decreased in summer under high and medium irrigation.
- Observation plant height at harvest decreased in summer under high and medium irrigation.
- Observation efficiency of water use decreased in summer under high and medium irrigation.
- Observation total water utilization per growth period decreased in summer under high and medium irrigation.
- Observation Daily water use increased in summer under high and medium irrigation.
- Intervention effect After irrigation resumed, dry matter production under low water was not significantly different from medium and high water.
- Intervention effect After irrigation resumed, harvest plant height under low water was not significantly different from medium and high water.
- Observation Alfalfa stand density declined across three production years.
- Intervention effect Water management did not significantly influence stand decline or root distribution.
- Observation Root morphology varied among genotypes, largely attributed to genetic expression.
- Intervention effect Water stress significantly increased root proline content.
- Intervention effect Water stress significantly decreased root arginine content.
- Intervention effect Water stress significantly increased root sucrose content.
