- Observation Medium-maturing rice fruit-bearing percentage was usually finalized 33-38 days after heading, 20 days before maturity.
- Observation The final determination period varied considerably across varieties and years.
- Observation Fruit-bearing percentage was destined around day 17 after heading in the early variety.
- Observation Fruit-bearing percentage was destined 22-27 days after heading in medium and late varieties.
- Observation Across cultivation and cutting conditions, the medium variety was destined around day 21 after heading.
- Observation The percentage of grains above a specific-gravity standard increased with maturity.
- Association At the critical period, percentage of grains above standard specific gravity was highly correlated with final fruit-bearing percentage.
- Method / resource The correlation could serve as a rice fruit-bearing forecast criterion.
- Recommendation The authors recommend a specific-gravity standard of 1.00 for the most exact forecasts.
