Other claims from this paper (12)
- Intervention effect Nitrogen application timing varied rice total dry weight at ear emergence and maturity.
- Intervention effect Early nitrogen application increased rice total dry weight and straw weight more than late application at ear emergence and maturity.
- Association Rice ear dry weight at maturity and grain yield had no definite relation to nitrogen application timing.
- Association Rice ear dry weight at maturity was not consistently related to dry weight produced after ear emergence or spikelet number across nitrogen timings.
- Association Rice ear dry weight at maturity correlated positively with dry weight produced after ear emergence except under the stated nitrogen treatment.
- Mechanism Rice ear dry weight at maturity was determined by the joint relation of spikelet number and postemergence dry weight.
- Mechanism Rice spikelet number was determined by the relation between nitrogen uptake before late spikelet initiation and subsequent uptake until ear emergence.
- Association Rice dry weight produced after ear emergence correlated positively with the product of ripening solar radiation and leaf nitrogen plus subsequent uptake.
- Method / resource Rice ear and shoot weights and their ratio at maturity could be represented as a function of nitrogen uptake at different stages.
- Association Rice ear-to-shoot dry weight ratio had no definite relation to grain yield, ripened-grain percentage, or shoot carbohydrate amount.
- Recommendation Rice ear-to-shoot dry weight ratio was unsuitable as a diagnostic index for yield, ripening percentage, or carbohydrate translocation.
- Recommendation Rice ear-to-shoot dry weight ratio could diagnose relations among dry weight production, spikelet number, and stage-specific nitrogen uptake.
