e0“The purposes of this study were to investigate the effects of wheat straw incorporation to soil and site-specific nitrogen management(SSNM) on the growth and grain yield of rice”
e5“The agronomic efficiency,recovery efficiency and physiological efficiency of nitrogen fertilizer under wheat residue incorporation were higher than those under the residue-removed”

Other claims from this paper (7)
- Intervention effect SSNM reduced nitrogen application in rice (40.0%41.7% as written) relative to farmers fertilizer-N practice.
- Intervention effect SSNM increased rice grain yield by 3.81% on average relative to farmers fertilizer-N practice.
- Intervention effect Wheat residue incorporation increased rice grain yield by 2.49% on average relative to residue removal.
- Intervention effect Wheat residue incorporation and SSNM increased nitrogen harvest index and agronomic and recovery efficiency of nitrogen in rice.
- Intervention effect Wheat residue incorporation and SSNM increased physiological efficiency and partial factor productivity of nitrogen in rice.
- Intervention effect Stems and tillers, leaf area index and biomass accumulation of rice were less or lower under residue incorporation and SSNM than under residue removal and FFP in the early growth period.
- Intervention effect Residue incorporation and SSNM increased the percentage of productive tillers, photosynthetic rate of flag leaves and root activities of rice during grain filling.
