The effects of deficit irrigation on turfgrass quality

Abstract

This study was carried out to determine the effects of deficit irrigation on water consumption and visual quality of some turfgrass at the Batı Akdeniz Agricultural Research Institute in 2008. In the study, two different turfgrass, Seaspray and TifBlair, varieties were used. Three different irrigation treatments were examined: 50% (I1), 75% (I2), and 100% (I3), of the evaporation measured in the Class A Pan, seven day intervals. Changes in the color and quality properties were monitored between June-October, 2008, depending on the irrigation levels. According to the results, seasonal evapotranspiration was ranged from 422.7-774.0 mm for Seaspray and 422.0-779.4 mm for TifBlair. The best visual quality was obtained from the I3 irrigation treatments.
