Claim · model-written summary
Nitrogen application from before cold exposure through five days after it reduced fertile grain number, especially with early application.
Glycine maxVerbatim
e0“N supply from before the low temperature treatment, till five days after the end of the treatment, resulted in a decrease in grain number, particularly, before the period of treatment and during the earlier period of N application, caused the greater decrease.”

Other claims from this paper (9)
- Association Nitrogen supply and temperature interacted significantly for pod set, ovule fertility and ovules per pod.
- Intervention effect Nitrogen improved grain yield at normal temperature relative to no nitrogen.
- Intervention effect Nitrogen at low temperature tended to reduce pod setting rate.
- Intervention effect Nitrogen at low temperature tended to reduce ovule fertility.
- Association Pod setting under low temperature was closely related to nitrogen application timing.
- Intervention effect Nitrogen before or during the first five low temperature days significantly reduced pod setting relative to no nitrogen.
- Observation Later nitrogen application caused less pod setting damage.
- Intervention effect Pod setting did not differ between 100 ppm and 40 ppm nitrogen.
- Intervention effect Nitrogen application reduced ovule fertility under low temperature.
