Determination of irrigation efficiency of barrier use in subsurface drip irrigation systems

This study was carried out to determine the effects of physical barriers on irrigation efficiency in subsurface drip irrigation systems. In the study, six growing plots (0,5 x 1,5 x 2,0 m) were prepared and grass was planted in these plots. Subsurface drip irrigation pipes were placed at different depths (10 and 15 cm) and different widths (20 and 30 cm) and physical water barriers were placed under pipes. The effects of using physical water barrier on water consumption of grass grown in sandy soil conditions were investigated and their performance on water saving was determined. At the end of study; it has been determined that water conservation was nearly 78% in the barrier used in cultivation areas as compared to those where the barrier was not applied.
