Other claims from this paper (11)
- Intervention effect Ni up to 0.5 mg L-1 did not change fruit Ni concentration under either nitrogen source.
- Intervention effect 0.5 mg L-1 Ni increased yield by 10% in urea-fed RS189.
- Intervention effect 0.5 mg L-1 Ni increased yield by 15% in urea-fed Vikima.
- Intervention effect Nitrate-fed plants had more total soluble solids than urea-fed plants.
- Intervention effect Fruit nitrate concentration was approximately 50% lower in urea-fed plants than nitrate-fed plants.
- Association Increasing Ni concentration further reduced fruit nitrate concentration.
- Association Photosynthesis increased continuously with Ni concentration in urea-fed plants.
- Observation Young-leaf N concentration was higher in urea-fed plants at 0.5 mg L-1 Ni.
- Observation Young-leaf nitrate reductase activity was higher in urea-fed plants at 0.5 mg L-1 Ni.
- Mechanism Authors attribute enhanced growth and yield under Ni to higher photosynthesis, N concentration and nitrate reductase activity.
- Recommendation Authors conclude 0.5 mg L-1 Ni improves yield, quality and NR activity in urea-fed cucumber.
