.) ( Jiang and Fry, 1998 ), and simultaneous drought and heat stresses in creeping bentgrass ( McCann and Huang, 2007 ). Ervin and Koski (2001) reported that TE resulted in lower evapotranspiration (ET) rates and reduced clipping yield in kentucky bluegrass

ryegrass and tall fescue that resulted in an increase of color ratings and clipping yields when treated with plant growth-promoting rhizobacteria. Several studies have been performed on perennial ryegrass for salt tolerance enhancement by applying

an indirect measure of the plant biomass produced from that plot. SAS Institute (1999) Proc Mixed was used to perform analysis of variance for turfgrass cover, quality, and clipping yield. All data were checked for equal variance and arcsine square

other cultivars. Herbicide treatment had no effect on clipping yield 4 WAT (data not shown), whereas only treated ‘TifEagle’ and ‘FloraDwarf’ bermudagrass had 32% and 25% reduced clipping yield 8 WAT from that nontreated, respectively. Table 5

compared with soil without CB ( Schnell et al., 2009 ). Similarly, incorporation of a 1.3-cm layer of CB within a 10- to 15-cm depth of excavated soil enhanced visual assessments of percent cover and clipping yields of seeded cool-season turfgrasses

and lower clipping yield as compared to foliar fertilization alone. Tank mixing organic amendment in liquid fertilizers resulted in an average increase of root/shoot biomass ratio from 0.62 to 0.65 grown in the 100% sand root zone. The effect of

establishment and use than traditional species. The objectives of this experiment were to determine if N levels affected turfgrass color, quality, clipping yield, and disease incidence of ‘Apollo’ Kentucky bluegrass, ‘Dura Blue’ and ‘Thermal Blue’ hybrid

( Poa pratensis L.). Fitzpatrick and Guillard (2004) noted that kentucky bluegrass showed inconsistent response to K fertilization. Across varying N rates and clipping management, K application had no effect on clipping yields and turf quality

and the second in the fall of 2006. Plant measurements included visual percent green ratings taken weekly, clipping yields taken biweekly, and shoot and root weights, which were taken at the conclusion of the 10-week study. Visual percent green ratings

understood. The application of PGRs has become a conventional golf course turf management practice for the regulation of turfgrass growth; suppression of certain weeds; reduction in mowing frequency and clipping yield; and enhancement of turfgrass color
