e2“Two different DI strategies supplying 70 and 50% of crop evapotranspiration (ETc) were compared with irrigation at the full rate of ETc”
e4“Severe water restrictions (DI=50% ETc) reduced fruit weight and crop production every year, with water-use efficiency values similar to those of the moderate DI (70% ETc)”

Other claims from this paper (7)
- Intervention effect Moderate deficit irrigation at 70% of ETc saved approximately 80 mm of water per season.
- Intervention effect Moderate deficit irrigation at 70% of ETc had no significant impact on water status and agronomic performance.
- Intervention effect Severe deficit irrigation at 50% of ETc gave water-use efficiency similar to moderate deficit irrigation at 70% of ETc.
- Intervention effect Mild water reductions did not evidence crop mineral nutrition imbalances or yield decrease.
- Recommendation A moderate water restriction can be applied in commercial orange orchards.
- Intervention effect Moderate deficit irrigation increased total soluble solids and titratable acidity of the fruit.
- Intervention effect Moderate deficit irrigation delayed fruit maturity.
