Other claims from this paper (8)
- Intervention effect Increased irrigation and prilled urea application increased grain yield of aerobic rice.
- Intervention effect Increased irrigation and prilled urea application promoted higher GHG emission in aerobic rice.
- Intervention effect Irrigation at 1.0 IW/CPE increased water use efficiency (WUE) of aerobic rice with 10% less water.
- Intervention effect Irrigation at 1.0 IW/CPE gave 12.08% lower GWP than irrigation at 1.2 IW/CPE in aerobic rice.
- Intervention effect Two foliar sprays of nano urea in place of 25% PU-supplied RDN significantly reduced GHG emission by about 6.5% in aerobic rice.
- Observation The nano urea and PU strategy gave the highest eco-efficiency of rice production (Rs. 12.26 kg-1 CO2 eq).
- Observation The nano urea strategy gave no significant yield reduction in aerobic rice.
- Recommendation Irrigation at 1.0 IW/CPE and 75% RDN through PU plus two NU sprays at 30 and 60 DAS is recommended for higher grain yield of aerobic rice.
