e0“In plants grown under both the high and medium water treatments it was found that dry matter production, plant height at harvest, efficiency of water use, and total water utilization per growth period decreased during the summer months while the daily rate of water utilization increased.”

- 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 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.
- Intervention effect Water stress did not affect root fructose and glucose levels.
- Observation Water-insoluble N was lower at midsummer than at the start and end of the season.
- Observation Water-soluble protein was lower at midsummer than at the start and end of the season.
- Intervention effect Total available carbohydrates and water-soluble protein decreased after harvest.
- Observation Water-insoluble N, soluble N, protein amino acid composition and free sugar did not change during regrowth.
- Observation TAC decreased in midsummer under medium and high irrigation each year.
- Observation TAC remained relatively constant in unharvested summer-stressed low-water plants unless rainfall stimulated growth.
