Abstract Three trickle irrigation schedules, two of which were scheduled according to soil water potential (ψ soil) (tensiometer method) and daily stem contraction (DSC) (dendrometer method) respectively and the other one was a schedule of restricted water supply, were applied to a mature peach orchard. The annual water application based on ψsoil was greater than that based on DSC. However, tree growth, fruit size and leaf water potential (ψleaf) on the trees in the dendrometer scheduling plot did not differ from those in the tensiometer scheduling plot while the premature fruit drop and fruit bud initiation were greatly different. The restricted water supply treatment limited significantly both tree and fruit growth. In addition, the lower ψleaf was observed on the trees in this plot. Further study shows that use of the dendrometer method for scheduling irrigation satisfies the water needs of the plant and that the tensiometer method is less accurate.
