Other claims from this paper (11)
- Observation Mean dry matter yield declined from first to final year.
- Intervention effect Annual yield declined from 1.53 under irrigation to 0.43 kg m-2 rainfed.
- Association Water use efficiency declined as irrigation decreased and over time.
- Association Plant stand declined as irrigation decreased and over time.
- Association Regression of yield on evapotranspiration gave R2 of 0.90.
- Observation Yield response was nearly linear in years two through four and linear in year five.
- Observation Middle-year yield–irrigation regressions overlapped an earlier study at the same location.
- Association Previous season water availability influenced starting soil water.
- Observation Plant-available water was depleted to at least 2.4 m in the first season.
- Observation Plant-available water was partially restored in only one dormant season.
- Observation Rainfed soil water content fell to 0.1 in all years.
