Other claims from this paper (17)
- Intervention effect Reclaimed water without water restriction increased olive fruit yield by 35% compared with control trees.
- Intervention effect Reclaimed water without water restriction did not result in higher olive oil yield.
- Intervention effect Regulated deficit irrigation did not decrease olive fruit yield.
- Intervention effect Regulated deficit irrigation tended to decrease olive weight.
- Intervention effect Regulated deficit irrigation increased olive oil yield by about 14.5%.
- Intervention effect Combined reclaimed water and deficit irrigation did not decrease olive fruit yield.
- Intervention effect Combined reclaimed water and deficit irrigation strongly reduced oil content per fruit dry weight by 40%.
- Intervention effect Both RDI treatments lowered acidity levels in olive paste compared with full irrigation treatments.
- Intervention effect Both RDI treatments reduced oil extractability and fatty yield.
- Intervention effect Reclaimed water exposure decreased olive oil quality.
- Intervention effect Reclaimed water exposure reduced oleic acid in olive oil.
- Intervention effect Reclaimed water exposure increased the C18:2/C18:3 ratio in olive oil.
- Intervention effect Reclaimed water exposure increased peroxides in olive oil.
- Intervention effect Reclaimed water improved total polyphenols in olive.
- Intervention effect Regulated deficit irrigation improved total polyphenols in olive.
- Observation In all cases the olive oil parameters met the legislation.
- Recommendation Reclaimed water and regulated deficit irrigation have potential to manage olive oil production.
