Abstract

Monitoring soil and tree water status continuous ly and in real time using sensor networks allowed regulated deficit irrigation (RDI) ma nagement in sweet cherry trees. Two deficit treatments were imposed, regulated deficit irrigation RDC 100-55 and sustained deficit irrigation RDS 85 , they saved 41% (2812 m 3 ·ha -1 ) and 23% (1612 m 3 ·ha -1 ) of the water amount applied during the first year of work compared to control treatment, CTL, watered to 110% of the ET cg . These savings did not cause midday stem water potentials lower than -0.7 and -1.5MPa during pre and postharve st, respectively. Moreover, there were no differences in production or per cherry unitary weight between treatments.
