Other claims from this paper (10)
- Intervention effect Cyanobacterial inoculation slightly raised rice yield, without a significant difference from non-inoculated treatments.
- Intervention effect Applying 60 kg Nha-l as urea or Azolla had similar effects on rice grain yield.
- Intervention effect Yield under combined urea and Azolla was not significantly different from 60 kg Nha-l urea alone.
- Intervention effect Yield under combined urea and Azolla was significantly higher than under 60 kg Nha-l Azolla alone.
- Intervention effect Azolla did not affect rice harvest index.
- Intervention effect Cyanobacteria did not affect rice harvest index.
- Association Rice nitrogen use efficiency decreased as nitrogen level increased.
- Intervention effect The highest rice plant nitrogen uptake occurred with Azolla and urea at 30 kg Nha-l each.
- Recommendation The authors considered Azolla alone or with urea more beneficial to rice than cyanobacterial inoculation.
- Intervention effect Azolla significantly increased soil organic carbon content.
