Other claims from this paper (8)
- Intervention effect Ammonium sulfate gave the best plant growth and nitrogen accumulation in tomato.
- Intervention effect Manure significantly enhanced pak-choi growth and nitrogen accumulation relative to no nitrogen.
- Intervention effect Tomato growth and nitrogen accumulation did not differ between manure and no nitrogen.
- Intervention effect Rhizosphere protease activity was highest with manure in both species.
- Intervention effect Rhizosphere protease activity was highest with manure in tomato.
- Association Rhizosphere protease activity correlated positively with total nitrogen accumulation only in pak-choi.
- Observation Excised pak-choi roots absorbed glycine significantly faster than tomato roots.
- Mechanism The authors propose rhizosphere protease activity and amino acid uptake capacity as two factors in organic nitrogen acquisition.
