Abstract
Root competition (tree density), summer pruning, and regulated irrigation were studied to determine whether they can be used to control tree vigor and productivity in ultra-dense orchards of peach [Prunus persica (L.) Batsch]. All methods appeared to inhibit tree growth, but regulated irrigation combined with root competition generated from high tree density was most effective. Fruit yields and fruit growth were significantly increased (up to 30%) by high tree density combined with low rate of water application when water stress limited shoot growth but stimulated subsequent fruit growth. Periods of low rate of water application are specified.Keywords
