Intervention effect Main spike grain yield decreased slightly at 0.2 x HS under low to medium salinity.
Intervention effect Main stem grain yield decreased more at 0.04 x HS.
Intervention effect High salinity caused larger decreases in main stem grain yield.
Observation High-salinity yield loss was more marked at 0.2 than 1 x HS.
Intervention effect Increasing salinity strongly decreased plant yield components other than thousand grain weight.
Observation A 50% grain yield decrease occurred at about 84 mM NaCl with 1 x HS.
Observation A 50% grain yield decrease occurred at about 72 mM NaCl with 0.2 x HS.
Observation Salt tolerance was higher at full macronutrient concentration.
Association Grain yield declines were closely related to declining leaf number.
Association Grain yield declines were closely related to declining tiller number.
Mechanism The authors infer salinity mainly affects early growth stages.
Recommendation The authors recommend increasing nutrient supply in nutrient-poor saline soils.
Recommendation The authors recommend salt elimination around roots during early wheat development.
Recommendation The authors recommend increasing main stem density by seeding more densely.
Recommendation Early salt elimination and increased seeding density were expected to raise yield more than added nutrients at moderate and sufficient nutrient levels.
