The present study examines the need for irrigation in pear trees (Pyrus Communis, cv. ‘Conference’) under low evaporative demand conditions, like in Belgium, in order to maintain a consistent fruit yield and high fruit size. To determine the sensitivity of the pear yield under low evaporative demand conditions three different orchards were monitored. The study shows that a Ψ soil of −60kPa during shoot growth has no effect on fruit yield but lower Ψ soil values induced a decline in both fruit size and total yield. Just as for arid environments a Ψ stem of −1.5MPa is related to negative yield responses. In dry conditions lower Ψ soil and Ψ stem values were observed in root pruned trees compared to not root pruned trees in the same irrigation treatment, however without yield decline. In one orchard a biannual bearing tendency was observed after root pruning. Furthermore intensive Ψ soil measurements show a high variation in Ψ soil between orchards, and within an orchard. This underlines the need for irrigation management on a parcel level and the need for new irrigation scheduling techniques which take the spatial variation in the orchard into account.
