- Association Grain yield with no N application was significantly lower at Chibi than at Jingmen in 2008 and 2009.
- Intervention effect modified farmers' fertilizer practice(FFP) increased grain yield over FFP at Chibi by 10.0% in 2008.
- Intervention effect super high yield(SHY) increased grain yield over FFP at Chibi by 2.3% in 2008.
- Intervention effect modified farmers' fertilizer practice(FFP) increased grain yield over FFP at Chibi by 16.6% in 2009.
- Intervention effect super high yield(SHY) increased grain yield over FFP at Chibi by 11.8% in 2009.
- Intervention effect modified SHY increased grain yield over FFP at Chibi by 22.6% in 2009.
- Intervention effect Modified FFP, SHY and modified SHY gave lower grain yield than FFP at Jingmen in 2008.
- Intervention effect modified FFP gave slightly higher grain yield than FFP at Jingmen in 2009, with a yield increase of 2.0%.
- Intervention effect SHY gave slightly higher grain yield than FFP at Jingmen in 2009, with a yield increase of 6.7%.
- Intervention effect modified SHY gave slightly higher grain yield than FFP at Jingmen in 2009, with a yield increase of 1.7%.
- Intervention effect Nitrogen agronomic efficiency and partial factor productivity of modified FFP and modified SHY were higher than FFP at Chibi.
- Intervention effect Partial factor productivity of N was significantly higher for the two modified treatments than FFP at Jingmen.
- Intervention effect Agronomic efficiency of N was slightly higher for the two modified treatments than FFP at Jingmen.
- Intervention effect N-use efficiency of SHY was far lower than that of other treatments at two sites over two years.
- Intervention effect Modified FFP and modified SHY achieved higher grain yield.
- Intervention effect Modified FFP and modified SHY achieved higher NUE.
- Intervention effect A 20% reduction of nitrogen relative to FFP could increase grain yield as well as NUE.
- Intervention effect Too much N application would not increase and would even reduce grain yield.
- Intervention effect Optimized nitrogen management could also improve the grain quality of rice.
