Other claims from this paper (11)
- Observation T7 reached a highest grain-filling rate of 77.8% under field conditions.
- Association T7 had significantly lower grain yield than FLY4 under the same conditions.
- Mechanism T7 had lower grain filling, spikelets per panicle, panicle density and harvest index, which the authors attributed as reasons for its lower yield.
- Intervention effect Nitrogen application had little effect on grain yield in both rice genotypes.
- Intervention effect Planting density had little effect on grain yield in both rice genotypes.
- Intervention effect Higher planting density significantly increased leaf area index and biomass accumulation.
- Association FLY4 had significantly higher nitrogen use efficiency than T7.
- Mechanism FLY4 had higher straw nitrogen content, which the authors linked to its higher nitrogen use efficiency.
- Intervention effect Increasing nitrogen application significantly reduced nitrogen use efficiency.
- Intervention effect Increasing nitrogen application significantly increased nitrogen uptake.
- Recommendation The authors recommend improving T7 yield by enhancing grain filling, panicle density and spikelets per panicle through genotype improvement.
