Day by day, the rational use of water is becoming more important in fruit production. The aim of this study was to evaluate the effect of using double drip line in pear (Pyrus communis) production, cv. Triunfo de Viena in comparison with the traditional system of one drip line per plant row. The research was based on the application of two specific processes, one consisting of a drip line per plant row with six emitters of 8 lt h-1 and another with two drip lines per plant row with three emitters of 8 lt h-1 each. Watermark sensors were used to measure and control soil matric potential. It covered 100% of potential evapotranspiration, which was 55.5 mm month-1. The results of the variables allow ground water irrigation scheduling and ensure adequate water supply during the period of water deficit. The double-line treatment did not differ significantly from the control in terms of production and fruit quality, which indicates that to use only one drip line will allow to get a similar yield and quality at a lower initial equipment cost.
