| Abstract/Contents: | "A large portion of the water used by cities is for the maintenance of lawns, sports fields, parks, and grounds. Cultural systems which allow turfgrass to persist under limited water resources conditions will reduce the dependency on potable water supplies and cultural inputs. Objectives of this research were to develop more complete information on turfgrass growth and quality responses to levels of controlled soil moisture conditions. Replicated field plots of Tifgreen bermudagrass (Cynodon dactylon x C. transvaalensis) were evaluated for water use and quality response using daily irrigation with and without soil moisture sensor control. Irrigation frequency and application rates were recorded using a water meter, hour meters on each valve, and rain gauges. Turfgrass quality was measured with a 252 band spectroradiometer and visual inspection. Vegetative indices to determine turfgrass quality were calculated from the spectroradiometer reflectance data. Results indicate an average 40-percent reduction in water use relative to Class A pan evaporation for turfgrass plots where irrigation schedule and amounts were controlled with soil moisture sensors. There were no significant differences in vegetative indices and visual quality among the irrigation treatments during the first two years of an ongoing experiment." |
