Other claims from this paper (12)
- Observation T3 soil water stayed near field capacity and did not differ from T2.
- Observation Soil moisture decreased during summer under T0 and T1, reaching 20.8% in T0 on 12 August before rainfall restored field capacity.
- Intervention effect Irrigated olive leaves had higher relative water content than rain-fed controls.
- Intervention effect T1 increased Nocellara del Belice olive yield by 200% versus rain-fed control.
- Intervention effect T2 increased Ascolana tenera olive yield by 233% versus control.
- Intervention effect T2 increased Kalamata olive yield by 47% versus control.
- Intervention effect Irrigated olives had higher oil yield, mainly because fruit yield increased.
- Observation Pulp-stone ratio and fruit triglyceride quantity were similar across irrigation treatments.
- Intervention effect Irrigation did not affect olive oil fatty acid composition.
- Intervention effect Irrigation decreased olive oil polyphenolic substance content.
- Mechanism The authors attribute the polyphenol decrease to water-deficit-related enzymatic activity rather than fruit ripening.
- Association The polyphenol decrease did not affect organoleptic oil quality or shelf-life.
