Other claims from this paper (15)
- Intervention effect Higher nitrogen rates increased tomato nitrogen uptake at some point in the season.
- Intervention effect Higher nitrogen rates increased snap-bean nitrogen uptake at some point in the season.
- Intervention effect Higher nitrogen rates increased sweet-corn nitrogen uptake at some point in the season.
- Intervention effect Higher nitrogen rates increased broccoli nitrogen uptake at some point in the season.
- Intervention effect Higher nitrogen rates increased collard nitrogen uptake at some point in the season.
- Intervention effect Higher nitrogen rates increased pumpkin nitrogen uptake at some point in the season.
- Observation Tomato final nitrogen accumulation exceeded fertilizer nitrogen applied at one or more rates.
- Observation Snap-bean final nitrogen accumulation exceeded fertilizer nitrogen applied at one or more rates.
- Observation Sweet-corn final nitrogen accumulation exceeded fertilizer nitrogen applied at one or more rates.
- Observation Broccoli final nitrogen accumulation exceeded fertilizer nitrogen applied at one or more rates.
- Observation Collard final nitrogen accumulation exceeded fertilizer nitrogen applied at one or more rates.
- Intervention effect Higher nitrogen rates increased final nitrogen accumulation only in the tomato/broccoli sequence.
- Intervention effect Lower planting density generally increased nitrogen accumulation per plant, whereas high density increased uptake per hectare across the vegetable crops.
- Intervention effect In 1984, pumpkin following tomato accumulated more nitrogen than in other sequences, the greatest preceding-crop effect.
- Mechanism The authors suggest cultural practices probably caused the previous-crop differences in pumpkin nitrogen accumulation.
