Other claims from this paper (13)
- Observation Leaf nickel concentration was highest at 1.2 mg kg−1 dry weight in urea-fed plants receiving 1 mg L−1 Ni.
- Intervention effect Adding Ni up to 0.5 mg L−1 did not change fruit Ni concentration in nitrate-fed cucumber.
- Intervention effect Increasing Ni from 0 to 0.5 mg L−1 significantly raised yield by 10% in RS189.
- Intervention effect Increasing Ni from 0 to 0.5 mg L−1 significantly raised yield by 15% in Vikima.
- Intervention effect Yield decreased at 1 mg L−1 Ni in urea-fed cucumber.
- Intervention effect Nitrate-fed cucumber had higher total soluble solids than urea-fed plants.
- Intervention effect Fruit nitrate concentrations in urea-fed cucumber were about 50% below nitrate-fed plants in both cultivars.
- Association Increasing solution Ni made the reduction in cucumber fruit nitrate concentration more pronounced.
- Association Photosynthesis rate increased with Ni concentration in urea-fed cucumber.
- Observation Young-leaf N concentration was higher in urea-fed cucumber at 0.5 mg l−1 Ni.
- Observation Young-leaf nitrate reductase activity was higher in urea-fed cucumber at 0.5 mg l−1 Ni.
- Mechanism The authors attributed enhanced growth and yield under Ni supplementation in urea-fed cucumber to higher photosynthesis, nitrogen concentration and nitrate reductase activity.
- Recommendation The authors concluded that 0.5 mg l−1 Ni supplements improve yield, quality and nitrate reductase activity in urea-fed cucumber.
