Other claims from this paper (8)
- Intervention effect Irrigation cutoff 40 to 50 days preharvest significantly reduced brix yield relative to the standard grower cutoff.
- Intervention effect Deficit irrigation significantly increased fruit SSC compared with the standard practice.
- Intervention effect Deficit irrigation caused no significant loss of brix yield compared with the standard practice.
- Intervention effect Fruit SSC rose with soil moisture stress from deficit irrigation, with late-maturing fruit up to 1.6 °brix higher than fruit maturing before significant stress.
- Intervention effect Once fruit reached the pink stage, its SSC was not affected by later soil moisture stress.
- Observation Applying 20% to 60% of reference evapotranspiration over the fruit ripening period gave acceptable SSC without significant brix yield reduction.
- Recommendation Brix monitoring of the earliest ripening fruit can help classify fields by the severity of irrigation deficit needed for desirable SSC.
- Recommendation Deficit irrigation started during early fruit ripening is a flexible tool for SSC management.
