Abstract/Contents:"Studies of the effect of irrigation frequency on the water requirements and quality of an established bermudagrass lawn were continued in 1982. High, medium and low frequencies with application rates of 0.9, 2.5 and 4.7 inches per application, respectively, were compared. The initial irrigation treatments were withheld until most of the available soil water was extracted. Soil water, prior to imposing the irrigation treatments, was extracted 1.5 to 2 feet deeper in the soil profile in the low frequency treatment compared to the high frequency treatment imposed in 1981. Apparently, more precipitation was stored in the wetter soil profile of the infrequent heavy irrigations. In 1982, high frequency (0.9 inch) irrigations were found to wet the soil profile to only 18 inches compared to 42 inches for medium frequency (2.4 inch) and 72 inches for a low frequency (4.7 inch) irrigations. Soil water was extracted 6-24 inches deeper in the medium and low frequency treatments compared to high frequency treatment. Frequent irrigations resulted in steady turf growth, but the poorest turf quality, as indicated by the number of days the turf was green to light green in color (97 days). Turf color was best for the longest period of time (125 days) in the low frequency treatment, but more mowing was required. The medium frequency irrigation resulted in a steady turf growth with good quality turf (110 days)."
