Given the need to improve the efficiency of water use, in this work a technique applied irrigation water intake to decrease with respect to the needs of the peach crop irrigation, for which the effect of the application of assessed Partial Rootzone Drying (PRD) by the production yield and the volume of water used by the crop to apply the PRD, which was to consider a sheet supply to 50% of evapotranspiration was determined crop (ETc) in non critical to the development of production phenological periods.The trial was conducted at the experimental plot to install a drip irrigation system, Faculty of Agricultural Engineering – UNALM, on 28 trees or experimental units of the Canary and Florida 39 varieties, in which two irrigation treatments were applied: PRD (in non-critical development of fruit) and the irrigation control (which consisted of a sheet supply to 100% of the ETc). Regarding the volume of water consumed in the evaluation period, the variety Florida 39, had a consumption of 498 m3/ha treatment PRD (T1) and 783,22 m3/ha in the control treatment (T2), T1 thus obtaining water saving irrigation of 36,35%, in the case of Canary variety volume of irrigation water with PRD (T1) was 683,11 m3/ha and control treatment (T2) was 990,81 m3/ha, T1 achieving a reduction in 31,05% of irrigation water compared to T2. The production values such as performance, average weight, average size and quantity of fruit between the two irrigation treatments applied PRD and control were statistically similar, so there was no significantly negative effects of the application the PRD on production. Canario variety performance with T1 was 22,91 Kg/tree and T2 of 20,76 Kg/tree; and in the case of the Florida variety T1 5,53 Kg/tree was obtained and T2 was 6,41 Kg/tree. PRD treatment application showed greater water use efficiency (WUE) compared to control treatment in the canary variety, as with the WUE T1 was 18,27 Kg/m3 and T2 was 10,99 Kg/m3 (60% less), having statistically significant difference. Florida 39 variety, the WUE was also higher in T1 with 4,4 Kg/m3 compared to T2 with 3,39 Kg/m3, although this difference was not statistically significant.
