Ryegrass Overseed Trials for 1986-1987Kopec, D. M., Mancino, C. F., Terrey, A., Gomperts, S. January 1988 (has links)
Ryegrass cultivars, experimental accessions, blends and composite mixtures were tested for overall adaptation to overseeded turfgrass management practices under desert conditions. Entries were significantly different from each other for color and overall turfgrass quality. Gennplasm for overseeding differs for tolerance to close mowing under desert conditions. In most cases, the better adapted entries had superior scores in two years of testing.

Effect of Salinity Stress on Development of Pythium Blight of Agrostis palustrisRasmussen, S. L., Stanghellini, M. E. January 1988 (has links)
Salinity stress predisposed cultivar Penncross creeping bentgrass to cottony blight caused by Pythium aphanidennatum at two temperature regimes. At 25-32 C, complete necrosis of all inoculated plants occurred at electrical conductivity (Ec) levels from 4.3-7.1 ds/m in 2 days, whereas at Ec levels of 0.5-2.8 ds/m death occurred within 3 days. At 25-27 C, complete necrosis of all inoculated plants occurred at Ec levels from 4.3-7.1 ds /m within a period of 5 days; no death was observed in control or inoculated plants at an Ec level of 0.5 ds/m. Increased salinity levels apparently affected the bentgrass rather than P. aphanidermatum. Mycelia' growth rate of the fungus was increased only slightly by salinity levels up to 7.1 ds/m. Zoospore production of P. aphanidermatum and two other species of Pythium decreased with increasing salinity levels up to 7.1 ds/m; production was completely inhibited at 14.2 ds/m.

Estimating Turfgrass Water Use with AZMETBrown, P., Kopec, D., Mancino, C. January 1988 (has links)
The Arizona Meteorological Network provides weather-based estimates of reference evapotranspiration (ETo) for much of southern, central and western Arizona. A simple 3-step procedure to convert ETo data into reliable estimates of turfgrass water use is described The procedure requires that AZMET ETo values be multiplied by a correction factor known as a crop coefficient (Kc). The selection of the Kc depends on the type and height of the turfgrass as well as desired turf quality. The procedure is well adapted for use on computers.
