Other claims from this paper (8)
- Intervention effect Yield was highest at the lowest soluble-fertilizer application rates.
- Intervention effect Root rot was greatest at the highest fertilizer rates.
- Intervention effect Root corkiness was greatest at the highest fertilizer rates.
- Association Ammonium accumulation in fumigated, urea-fertilized soil reduced early yields.
- Intervention effect Fumigated plots had more severe root rot than non-fumigated checks.
- Intervention effect Fumigated plots had more severe root corkiness than non-fumigated checks.
- Observation The observed root symptoms resembled symptoms attributed elsewhere to fungal attack.
- Mechanism The authors infer that several causes, separately or together, can produce the root-rot symptom complex.
