Other claims from this paper (8)
- Observation Nitrogen release from controlled release urea closely matched rice nitrogen requirements.
- Intervention effect Commingling controlled release urea with rice seeds increased root-zone nitrogen concentration.
- Intervention effect Commingling controlled release urea with rice seeds enhanced leaf glutamine synthetase, GOGAT, and nitrate reductase activities.
- Intervention effect At the same nitrogen rate in 2008, apparent nitrogen use efficiency with CRU at 300 kg N ha −1 was 22.9% higher than with conventional urea.
- Intervention effect CRU at 200 kg N ha −1 produced 3 to 5.9% more grain than urea at 300 kg N ha −1.
- Intervention effect Placing CRU with rice seeds significantly increased soil nitrogen availability.
- Intervention effect Placing CRU with rice seeds improved rice growth.
- Intervention effect Placing CRU with rice seeds allowed less nitrogen fertilizer for greater rice grain yield.
