Other claims from this paper (15)
- Intervention effect By the first season end, blueberry plants were largest with drip, intermediate with microsprays, and smallest with sprinklers.
- Observation The first-season size ranking did not persist in the second season.
- Intervention effect Drip-irrigated plants had lower pruning weights than sprinkler or microspray plants.
- Intervention effect Drip-irrigated plants had half the shoot and root dry weight of sprinkler or microspray plants.
- Observation The field was infested by root rot.
- Association Lower drip-associated growth was associated with higher Phytophthora cinnamomi infection.
- Association Phytophthora infection increased with water application regardless of irrigation method.
- Observation Phytophthora infection averaged 14% under drip irrigation.
- Observation Phytophthora infection averaged 7% under sprinklers and microsprays.
- Observation Blueberry roots were infected by Pythium species.
- Association Pythium infection increased with total water applied.
- Association Pythium infection was similar across irrigation methods.
- Intervention effect Drip irrigation maintained higher soil water content near plant bases than sprinklers and microsprays.
- Mechanism Higher soil water under drip was interpreted as favoring root rot.
- Recommendation Sprinklers and microsprays may be better than drip at sites prone to root rot.
