Abstract:

In order to assess the subsurface drip irrigation (SDI) system on growth and yield components of grape, field experiment was designed with five treatments and three replications. The same irrigation set time and irrigation frequencies were used for each treatment, but different irrigation water volumes were measured due to use of different manifold pressures head compared to the field system pressure. Growth parameters and yield data were collected during the experimental period. Based on the results of this research, application of SDI caused better condition for grape growth parameters, especially compared to bubbler irrigation and surface drip irrigation (DI). Furthermore, application of SDI in 60 cm depth caused highest yield component and therefore highest water use efficiency compared with bubbler, DI, furrow irrigation and SDI in 30 cm depth.
