Other claims from this paper (7)
- Intervention effect Withholding irrigation before or after veraison imposed significant water deficits.
- Intervention effect Doubling irrigation increased fruit growth, cluster initiation, and bud differentiation.
- Intervention effect Increasing irrigation above standard practice raised yield by 30% to 40%.
- Observation Treatment differences in vine water status emerged only after fruit set.
- Intervention effect Preveraison or postveraison deficits inhibited yield, fruit expansion, and bud development, with earlier deficits more inhibitory.
- Intervention effect All water deficits depressed second crop development.
- Association Variation in berries per cluster explained the greatest amount of yield variation.
