| Abstract/Contents: | "Proper irrigation management requires knowledge of crop water use rates. Approximately 25% of turfgrasses are managed under some level of shade, suggesting knowledge of how species and their water use rates respond to various environments could be of importance when estimating water use rates at the landscape scale. A study was conducted at the Turf Research Station in Stillwater, Oklahoma to quantify the water use rate of five bermudagrasses (Cynodon spp.) and two zoysiagrasses (Zoysia japonica Steud.) under full sun and moderate shade conditions. The study was replicated three times in a randomized complete block design and the levels of each factor applied in factorial. Shade was applied by a horticultural shade fabric nominally rated to reduce incoming radiation by 44%. The fabric was suspended horizontally 0.5 m above the turf surface using a PVC frame. Within the center of each 2m x 2m plot, a mini lysimeter constructed of PVC pipe (15 cm diameter by 36 cm length by 30 cm depth) was installed inside a plastic sleeve onto a gravel sub-surface such that the canopy of the mini lysimeter was even with the canopy of the grass in the plot. Evapotranspiration data were collected on three to four consecutive days within a week using early morning measurements which consisted of weighing the mini lysimeters at field capacity the first day, then weighing each lysimeter before 9:00am on the second, third and fourth days. Preliminary results suggest water use rates under shade largely followed reductions in solar radiation. These findings will contribute to better understanding of irrigation water requirements for shaded landscapes." |
