Other claims from this paper (9)
- Intervention effect Nitrogen fertilization increased plant height of early rice by 16.07% relative to the no-nitrogen treatment.
- Intervention effect Nitrogen fertilization increased effective panicles of early rice by 28.76% relative to the no-nitrogen treatment.
- Intervention effect Nitrogen fertilization increased total grain number per panicle of rice by 12.54% relative to the no-nitrogen treatment.
- Intervention effect Nitrogen fertilization increased seed setting rate of rice by 1.34% relative to the no-nitrogen treatment.
- Intervention effect Nitrogen fertilization increased average rice yield by 41.26% relative to the no-nitrogen treatment.
- Intervention effect Grain number per panicle of rice decreased when fertilizer dosage was raised above 330 kg/ha N.
- Intervention effect Seed setting rate of rice decreased when fertilizer dosage was raised above 330 kg/ha N.
- Intervention effect Yield of rice decreased when fertilizer dosage was raised above 330 kg/ha N.
- Recommendation Applying 165-330 kg/ha nitrogen fertilizer is suitable for high rice yield and high N fertilizer efficiency in middle Guangxi.
