“…In order to account for percolation, soilwater balance was calculated using moisture measurements for the 0.6 m soil profile. Doty et al (1990) noted that a large portion of grass water uptake occurs at the 0-25 cm soil profile; therefore, effective rooting depth was assumed to be 0.3 m.…”

This study examined the effects of different irrigation levels and nitrogen rates on perennial ryegrass (Lolium perenne L.) evapotranspiration and quality in a sub-humid climate over a two-year period (2007)(2008). Nitrogen treatment (25 kg N ha -1 ; N 1 and 50 kg N ha -1 ; N 2 ) varied among main plots and irrigation levels (25%; I 1 , 50%; I 2 , 75%; I 3 , 100%; I 4 and 125%; I 5 of the Class A pan evaporation) by subplot. Irrigation was performed at 3-day intervals during May-September using a pop-up sprinkler irrigation system, and N applied as a monthly rate during the irrigation period. Seasonal turfgrass evapotranspiration was found to vary by treatment from 309-1178 mm in 2007 and from 379-1097 mm in 2008. Turfgrass visual color, quality and clipping yield were shown to decrease significantly with decreases in irrigation water and N fertilizer. The study findings demonstrated that under a non-limiting water supply, irrigation could be decreased by adjusting N fertilizer rates according to turfgrass visual color and quality and that N 1 I 4 or N 2 I 3 treatments can maintain acceptable turfgrass visual color and quality under sub-humid climatic conditions.

“…For the calculation, I was measured using water meters, and P was observed at the meteorological station. Doty et al (1990) noted that a large portion of grass water uptake (approximately 60%) was in the upper 0-0.25 m soil profile, while the rest was at the depth of 0.25-0.75 m. Therefore, the effective rooting depth was regarded as 0.30 m in our calculations. In the study, it is assumed that the soil water Figure 2 Change in color scores of eight bermudagrass cultivars over 16 weeks in response to three irrigation treatments, I 1 = 0.50 evaporation from class A pan (Epan) (a), I 2 = 0.75 Epan (b) and I 3 = 1.00 Epan (c).…”

This study was carried out to determine the effects of deficit irrigation on evapotranspiration and quality of bermudagrass (Cynodon dactylon L.) turfgrass cultivars under Mediterranean conditions. Eight bermudagrass turf cultivars ‘Blackjack’, ‘Mohawk’, ‘Princess’, ‘Riviera’, ‘Sahara’, ‘Sultan’, ‘Swi–1044’ and ‘Swi–1045’ were used. Irrigation experiments were conducted from June to October 2008. Experimental plots were irrigated at 7 days intervals, at three levels of irrigation based on the potential evaporation as measured by a Class A pan (Epan) as follows I1 = 0.50 Epan, I2 = 0.75 Epan and I3 = 1.00 Epan. Volumetric soil water content was measured using soil moisture meter before and after irrigation. It was found that the irrigation levels affect sward color, visual quality and leaf firing. Among the cultivars, ‘Swi–1045’ and ‘Princess’ showed the best color and quality while ‘Mohawk’ and ‘Sultan’ gave the poorest color and quality in all irrigation levels. No statistically significant differences between I1 and I2 irrigation treatments were obtained in terms of color, quality and leaf firing for bermudagrass cultivars. It is concluded that when the amount of water is limited in arid and semiarid regions such as the Mediterranean, the bermudagrass can be irrigated at a level of 50% of pan evaporation to get an acceptable visual quality with improved water conservation.
