Title
Effects of Water and Fertilizer on Nitrogen Use Effeciency and Balance in Lowland Rice Field
Pingcang Zhang Journal of Irrigation and Drainage 2009
Other claims from this paper (9)
- Observation About half of the total nitrogen in rice plants accumulated in the grain.
- Intervention effect Nitrogen accumulation differed between water saving and traditional flooding irrigation on stem, green leaves and grain.
- Intervention effect No significant difference in nitrogen accumulation between water saving and flooding irrigation on yellow leaves and unfilled grain.
- Method / resource The minus method gave higher nitrogen use efficiency in rice than the isotope tracer technique.
- Intervention effect Nitrogen use efficiency was higher under alternate wetting and drying irrigation than under continuous flooding irrigation.
- Intervention effect Nitrogen use efficiency was higher at low than at high nitrogen level.
- Observation Isotope tracer balance attributes 20.4% to 37.7% of nitrogen in lowland rice to soil residue.
- Observation Isotope tracer balance attributes 9.2% to 36.4% of nitrogen in lowland rice to crop utilisation.
- Observation Isotope tracer balance attributes 0.3% to 16.4% of nitrogen in lowland rice to leaching.
