Other claims from this paper (8)
- Intervention effect Combined 150 kg/hm2 nitrogen and 3 000 kg/hm2 organic manure improved rice yield by 9.8% to 17.7%.
- Observation Nitrogen use efficiency was 47.9% in rice.
- Intervention effect Nitrogen use efficiency with combined 150 kg/hm2 nitrogen and organic manure was 4.8% higher than with chemical fertilizers only.
- Intervention effect Combining 210 kg/hm2 nitrogen with 3 000 kg/hm2 organic manure decreased rice yield and nitrogen use efficiency.
- Observation Nitrate was the main type of nitrogen loss in paddy fields.
- Intervention effect Organic manure at 3 000 kg/hm2 reduced nitrogen loss through runoff from 0.85% to 0.70% at 150 kg/hm2 nitrogen.
- Intervention effect At 210 kg/hm2 nitrogen, organic manure had no remarkable effect on nitrogen loss.
- Recommendation A combination of 3 000 kg/hm2 organic manure with 150 kg/hm2 nitrogen is recommended for rice in the Hangjiahu area.
