e1“alfalfa (Medicago sativa L.)”
e0“Increased salinity (0–100 mM NaCl) substantialy reduced the dry weight of roots and shoots, relative growth rate (RGR) of the plant, relative multiplication rate of root, mean extension rate of root, number of root branches, and root length.”

- Intervention effect Increased salinity reduced dry weight of roots and shoots in alfalfa.
- Intervention effect Increased salinity reduced relative growth rate (RGR) of the plant in alfalfa.
- Intervention effect Increased salinity reduced relative multiplication rate of root in alfalfa.
- Intervention effect Increased salinity reduced mean extension rate of root in alfalfa.
- Intervention effect Increased salinity reduced number of root branches in alfalfa.
- Intervention effect Additional nitrogen moderated the salinity effects on alfalfa growth and roots.
- Intervention effect Nitrate nitrogen promoted shoot and root dry weight and root lengths more than ammonium nitrogen.
- Intervention effect Ammonium nitrogen increased root tip number more than nitrate nitrogen at all salinity levels.
- Intervention effect Salinity affected root length more than root tip number per alfalfa plant.
- Observation Alfalfa plants at the second harvest were relatively tolerant of salinity and nitrogen levels.
- Recommendation The authors suggest nitrate supply to improve alfalfa vegetative growth under salinity.
- Observation Alfalfa plants did not require excessive nitrogen for further shoot regrowth during vegetative growth.
- Association Moderation of salinity effects depended on nitrogen form, concentration and growth stage.
