Other claims from this paper (5)
- Intervention effect Without NBPT, no simulated rainfall gave greater rice yield than rainfall after or before nitrogen application.
- Intervention effect NBPT-treated urea raised rice yield by 6.9 to 21.3% within each rainfall timing.
- Intervention effect Nitrapyrin rate had no yield effect in 2013.
- Intervention effect NP-treated urea reduced rice yield by 5.6% against untreated urea in 2014.
- Intervention effect Applying urea to moist soil followed by drying or dry soil followed by rain yielded less rice than dry soil remaining dry until flooding.
