Other claims from this paper (14)
- Intervention effect Direct seeding increased rice vegetative growth.
- Intervention effect Direct seeding shortened rice crop duration by more than one week.
- Intervention effect Broadcast seeding produced the highest tiller number, followed by row seeding and hill-wise dibbling.
- Association Relative tillering rate correlated significantly with relative growth rate.
- Association Greater growth in direct-seeded rice decreased tissue nitrogen concentration.
- Mechanism Lower tissue nitrogen concentration impeded sink formation.
- Association In direct-seeded rice, grain yield correlated significantly with spikelet number per panicle.
- Association In direct-seeded rice, grain yield did not correlate significantly with panicle density.
- Association In transplanted rice, grain yield correlated with panicle density but not spikelet number.
- Intervention effect Band fertilizer placement significantly increased rice grain yield.
- Intervention effect Band placement enabled split nitrogen application and increased reproductive-stage plant nitrogen concentration.
- Intervention effect Leaf area index was higher in direct-seeded than transplanted rice.
- Association Vegetative-stage canopy photosynthesis was limited by leaf area index.
- Association Reproductive-stage canopy photosynthesis was limited by foliage nitrogen concentration.
