Other claims from this paper (7)
- Intervention effect Irrigation improved lettuce establishment, especially with Alcosorb.
- Observation Alcosorb avoided increased soil impedance associated with irrigation.
- Intervention effect Alcosorb was a more effective seed cover than peat and vermiculite mix.
- Observation Alcosorb was better suited for mechanical metering.
- Recommendation The dibber drill was considered a realistic and cheaper alternative to transplanting for later season lettuce establishment.
- Intervention effect Dibber drilling reduced calabrese seedling emergence percentage relative to coulter drilling.
- Mechanism Seed coat damage during dibber sowing may explain lower calabrese emergence.
