Other claims from this paper (13)
- Intervention effect Plant density 6.75 per m2 with 210 kg N ha-1 can maintain high cotton yield compared with the local farmers combination.
- Intervention effect Plant density 6.75 per m2 with 105 kg N ha-1 achieved high cotton yield only in the first year.
- Association Biological yield of cotton increased with higher N rate and plant density.
- Intervention effect D6.75N210 increased N agronomic efficiency by 30.2 compared with D5.25N315.
- Intervention effect D6.75N210 increased N recovery efficiency by 54.1% compared with D5.25N315.
- Intervention effect D6.75N105 increased NAE by 104.8 compared with D5.25N315.
- Intervention effect D6.75N105 increased NRE by 88.1% compared with D5.25N315.
- Intervention effect Soil inorganic N decreased sharply under 105 kg N ha-1 in cotton stubble fields.
- Intervention effect Soil inorganic N showed no change under 210 kg N ha-1 at 6.75 plants per m2.
- Intervention effect N deficit occurred under 105 kg N ha-1 in cotton stubble fields.
- Intervention effect No N deficit occurred under 210 kg N ha-1 at 6.75 plants per m2.
- Intervention effect Net photosynthetic rate and leaf N concentration of cotton were higher under 210 to 420 kg N ha-1 than under 0 or 105 kg N ha-1 at all three densities.
- Recommendation D6.75N210 is a superior combination for cotton stubble retaining fields in the Yellow River Valley and similar ecologies.
