Other claims from this paper (10)
- Observation Midday stem water potential in the 100% and 115% irrigation treatments generally stayed above the stress threshold.
- Intervention effect Dense planting under 100% of the baseline irrigation dose caused transient severe summer water stress in trees, coinciding with reduced productivity in D. lotus.
- Intervention effect Yield was largely unaffected by increasing the irrigation dose.
- Intervention effect D. virginiana rootstock induced greater vigour than D. lotus.
- Intervention effect D. virginiana gave no consistent yield advantage over D. lotus.
- Association The lack of a yield advantage for D. virginiana was partly associated with lower crop load and greater physiological fruit drop.
- Intervention effect At the hectare scale the denser planting layout tended to improve productivity.
- Intervention effect Sustained deficit irrigation reduced fruit abscission relative to flowering by about 14% against a D. lotus control at 100% BID.
- Intervention effect Sustained deficit irrigation maintained yield relative to the control.
- Intervention effect Sustained deficit irrigation maximised irrigation water productivity.
