Other claims from this paper (7)
- Intervention effect Nitrogen rates increased biomass production and leaf N content in the absence of Mo supply.
- Intervention effect Mo supply did not affect NR activity in leaves.
- Intervention effect Mo supply increased nitrogen use efficiency by 48% at the lowest N rate.
- Association Mo uptake increased with N doses.
- Association Mo-leaf contents reached a maximum of 17.5 mg kg−1 at the 151.2 mg kg−1 N rate.
- Intervention effect Mo supply increases Mo-leaf content in sugarcane.
- Mechanism Mo application may increase NUE by affecting other N-metabolism processes rather than NR activity.
