Other claims from this paper (9)
- Observation The photosynthesis rate of sugar beet follows a single-peak curve over time.
- Observation NRA, NiRA and total chlorophyll content of sugar beet change along double-peak curves over time.
- Observation The chlorophyll content peaks earlier than NRA, and NRA peaks earlier than NiRA in sugar beet.
- Intervention effect Under 120 kg/ha nitrogen, photosynthesis rate and total chlorophyll content of sugar beet significantly increased.
- Intervention effect Under 120 kg/ha nitrogen, NRA and NiRA of sugar beet significantly increased.
- Intervention effect Under 180 kg/ha nitrogen, photosynthesis rate of sugar beet was not obviously changed compared with 120 kg/ha.
- Intervention effect Under 180 kg/ha nitrogen, NRA and NiRA of sugar beet improved to some extent compared with 120 kg/ha.
- Intervention effect Sugar beet yield increased with increasing nitrogen level.
- Intervention effect Highest sugar yield of sugar beet was obtained under 120 kg/ha nitrogen.
