Other claims from this paper (10)
- Observation Root distribution effects were mainly in the top 40-cm.
- Intervention effect Irrigation amount did not significantly affect average RLD.
- Intervention effect Water salinity below 3.2 dS m−1 stimulated root growth at heading in 10–40-cm soil.
- Intervention effect Salinity below 3.2 dS m−1 caused no obvious yield reduction.
- Intervention effect Salinity below 3.2 dS m−1 caused no obvious salt accumulation.
- Intervention effect Salinity of 5.2 and 7.1 dS m−1 decreased RLD in the 0–10-cm layer.
- Intervention effect Salinity of 5.2 and 7.1 dS m−1 decreased root biomass at maturity.
- Intervention effect Salinity of 5.2 and 7.1 dS m−1 significantly decreased yield in both years.
- Observation Irrigation amount by salinity interaction did not significantly affect roots or yield.
- Recommendation In no rainfall, irrigation of 205–355 mm and salinity of 0.65–5.2 dS m−1 can ensure 70% yield.
