- Intervention effect Potassium increased grain yield.
- Intervention effect Lodging resistance did not differ significantly between 90 and 120 kg ha −1 potassium.
- Intervention effect Grain yield did not differ significantly between 90 and 120 kg ha −1 potassium.
- Intervention effect Potassium increased soybean stem diameter by 17.8% in intercropping.
- Intervention effect Potassium increased soybean stem diameter by 15.5% in monoculture.
- Intervention effect Potassium reduced L/D by 27.2% in intercropping.
- Intervention effect Potassium reduced L/D by 26.8% in monoculture.
- Observation At high potassium inputs, phenylalanine ammonia‐lyase was 2.6% higher in intercropping than monoculture.
- Observation At high potassium inputs, cinnamyl alcohol dehydrogenase was 3.9% higher in intercropping than monoculture.
- Association Lodging resistance index depended on stem enzyme activity at 93.5% in intercropping.
- Association Lodging resistance index depended on stem enzyme activity at 75.3% in monoculture.
- Association The L/D relation with lodging resistance index was −81.0% in intercropping.
- Association The L/D relation with lodging resistance index was −83.8% in monoculture.
- Mechanism The authors conclude potassium improves lodging resistance and yield through stem diameter, lignin synthesis and L/D.
