Productive and vegetative tree responses were analyzed during 3 consecutive years in peach [ Prunus persica (L.) Batsch cv. Sudanell] plots subjected to three regulated deficit irrigation (RDI) strategies plus a control treatment. A postharvest RDI treatment (RDI-P) was irrigated at 0.35 of after harvest. Stage II (RDI-SII) 0.5 the lag phase fruit growth curve. The third (RDI-SII-P) applied control. treatment, like RDI-P RDI-SII-P when not receiving RDI, 100% water budget scheduling 1994 1996, full crop years, 80% 1995, an off year with very small crop. carry-over effect highly significant all parameters measured experiment. general stress did affect return bloom set, whereas apparently reduced both parameters. As consequence, counts load manifested marked differences between treatments, which also correlated changes size.
