Other claims from this paper (17)
- Intervention effect Wet seeding in spots raised grain yield by 11.8% versus transplanting.
- Observation Higher tillering, more panicles and better grain filling accompanied the WSS yield advantage.
- Intervention effect Weed population under wet broadcast seeding was four times that under transplanting.
- Intervention effect Weed population under spot wet seeding was twice that under transplanting.
- Observation Transplanting required 1041.2 ha-mm of water.
- Observation Wet seeding required 941.5 ha-mm of water.
- Observation Dry seeding required 915.0 ha-mm of water.
- Observation Water use efficiency was lowest under dry seeding.
- Observation Water use efficiency was highest under spot wet seeding.
- Intervention effect Line wet seeding had 9.7% higher water use efficiency than transplanting.
- Intervention effect Spot wet seeding had 24.0% higher water use efficiency than transplanting.
- Intervention effect Broadcast wet seeding had 10% less water use efficiency than transplanting.
- Intervention effect Wet seeding reduced labor requirements by 5-20% versus transplanting.
- Observation Line and spot seeding required more sowing labor.
- Observation Weeding was easier and less labor intensive with line and spot seeding.
- Observation Wet and dry seeding required less labor during the peak transplanting period.
- Recommendation The authors identify spot wet seeding as an improved rice planting method with higher yield, lower water and labor needs, and easier weed management.
