Other claims from this paper (11)
- Intervention effect Severe nitrogen stress produced fewer, smaller and thicker tomato leaves.
- Intervention effect Tomato leaf area index rose from about 0.75 to about 3 with increasing nitrogen.
- Intervention effect Tomato radiation use efficiency rose by less than 30% with increasing nitrogen.
- Intervention effect Nitrogen limited tomato leaves had lower nitrogen concentration, from 40 to as little as 15 mg per g.
- Observation Well fertilized tomato leaf nitrogen concentration fell from 55–65 mg per g initially to 20–35 mg per g at harvest.
- Observation Tomato fruit nitrogen concentration was 30–35 mg per g.
- Observation Tomato stem nitrogen concentration was 15–25 mg per g.
- Intervention effect Severe nitrogen stress affected tomato leaf and stem nitrogen concentrations most, while fruit nitrogen varied less.
- Observation Under nitrogen supply below 180 kg per hectare, tomato nitrogen use efficiency was about 0.4 Mg fresh fruit per kg nitrogen.
- Observation Nitrogen fertilizer recovery in drip irrigated tomato was 0.36–0.74.
- Observation Nitrogen fertilizer recovery in subirrigated tomato was 0.61–0.96.
