Evaluación de dos sistemas de riego por goteo en la producción y la calidad de la fruta de pera (Pyrus communis L.) variedad Triunfo de Viena

The rational use of water becomes every day ever more important in fruit production. The aim of this study was to evaluate the effect of the use of double drip line from a line by line plant in pear (Pyrus communis) production, cv. Triunfo de Viena. The research was based on the application of two specific processes, one consisting of a drip line per row of plants with six emitters of 8 1t h^-1 and another with two drip lines per row of plants with three emitters of 8 1t h^-1 each. Watermark sensors were used to measure and control the soil matric potential. It covered 100% of potential evapotranspiration, which amounted to 55.5 mm month^-1. The results of the variables permitted 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 permit to get a similar yield and quality at a lower initial equipment cost.
