Title
Effects of Nitrogen Management on Yield and Quality of Late Rice and Nitrogen-use Efficiency
Xiangming Zhang T'u Jang T'ung Pao 2008
Other claims from this paper (13)
- Intervention effect Postponed nitrogen fertilization maintained suitable NH4+-N concentration.
- Intervention effect Postponed fertilization promoted late rice growth, yield, dry matter and nitrogen accumulation.
- Observation Rice yield was maximal with 53.8% of nitrogen as basal fertilizer.
- Association Milling quality improved as the panicle fertilizer ratio increased.
- Association Appearance quality worsened as the panicle fertilizer ratio increased.
- Intervention effect Postponing nitrogen fertilization improved nitrogen-use efficiency.
- Observation At 40.3% basal nitrogen, late rice nitrogen uptake was maximal.
- Observation At 40.3% basal nitrogen, nitrogen-use efficiency was maximal.
- Association Soil nitrogen dependency had a parabolic relationship with basal fertilizer ratio.
- Observation Soil nitrogen dependency was lowest at a 40.0% basal fertilizer ratio.
- Association Nitrogen harvest index increased as basal fertilizer application decreased.
- Association Nitrogen requirement per 100 kg grain increased as basal fertilizer application decreased.
- Recommendation The authors recommend 40%-50% basal, 20%-30% tiller and 20%-30% panicle fertilizer.
