Partial rootzone drying does not affect fruit yield of raspberries

Pot experiments with split-root plants and two years of ®eld experiments with manipulation of soil water content have shown that partial rootzone drying (PRD) does not affect yield in raspberries, Rubus idaeus L. `Glen Ample' and `Glen Prosen'. In some cases PRD can reduce stomatal conduct...

Description
Summary:Pot experiments with split-root plants and two years of ®eld experiments with manipulation of soil water content have shown that partial rootzone drying (PRD) does not affect yield in raspberries, Rubus idaeus L. `Glen Ample' and `Glen Prosen'. In some cases PRD can reduce stomatal conductance, thus reducing water loss. This results in a higher water use ef®ciency. Partial rootzone drying may be an ef®cient irrigation strategy where raspberries are produced under shelter.
