- Intervention effect Drought reduced growth across all bean lines.
- Intervention effect Drought decreased chlorophyll content, especially in DOR 364-NN and BAT 477-NN.
- Intervention effect Drought reduced nodule size most in DOR 364, by 21.6%.
- Association Loss of nitrogen fixation during drought was associated with lower shoot nitrogen percentage.
- Association Loss of symbiotic nitrogen fixation in DOR 364-NN and BAT 477-NN negatively affected root architecture during drought.
- Observation Under drought, BAT 477-NN had about 50% lower root architectural trait values.
- Association Nitrogen fixation capability was associated with better harvest index and seed yield.
- Association Well-watered nitrogen-fixing lines had higher harvest index than nonfixing lines.
- Association Well-watered fixing lines yielded 2.6–2.8 t/ha versus 1.4 t/ha in nonfixing lines.
- Intervention effect Drought lowered harvest index in all tested lines, significantly only in DOR 364-NN.
- Intervention effect Drought lowered seed yield in all tested lines, significantly in DOR 364-NN and BAT 477-NN.
