Other claims from this paper (5)
- Association Soybean nitrogen-fixing ability decreased linearly with increasing soybean looper defoliation.
- Intervention effect Control soybean plants had fivefold greater acetylene reduction than plants with 77% defoliation.
- Intervention effect Defoliation reduced soybean nodule number and weight.
- Intervention effect Defoliation reduced soybean nodule-specific activity.
- Intervention effect Nodule-specific activity was unaffected below 47% defoliation.
