NUTRITIVE VALUE OF SEDGE AND KENTUCKY BLUEGRASS HAYS GROWN IN ALBERTA

Measuring sod strength of Kentucky bluegrass and Supina bluegrass

The extent of root, rhizome, and/or stolon growth determines turfgrass sod maturity. In 1998, at Michigan State University, the Calrochan Sod Puller (CSP) was developed to measure the force necessary to tear a piece of sod. The CSP uses a battery powered hydraulic pulley to provide a consistent pulling force, and is attached to a load cell. In August 1999, sod strength measurements of different...

Heat Tolerance Screening of Field-Grown Cultivars of Kentucky Bluegrass and Perennial Ryegrass

The quality of cool-season turfgrasses frequently declines during periods of high temperature stress. Simple tests are needed to rapidly identify heat tolerant germplasm for incorporation into breeding pro­ grams. Facilitative screening tests have been devised, however, in the few studies that have been performed only immature and green­ house or growth chamber-grown plants have been evaluated....

Late Fall Fertilization of Kentucky Bluegrass

not result in higher color ratings in the spring and resulted in inefMany turfgrass managers apply a portion of the total yearly N to cool-season turfgrasses in the late fall (November). The purpose of this field study was to compare fertilization programs with and without N applications in November using both slow-release and soluble N sources. Turfs of two different cultivars of Kentucky blue...

Salinity Tolerance of Kentucky Bluegrass as Affected by Salicylic Acid

Salinity is one of the greatest environmental challenges facing plant growth and development in the 21st century. Salicylic acid (SA) is a phenolic compound and signal molecule involved in the regulation of plants responses to biotic and abiotic stresses. This greenhouse experiment was conducted to determine effects of SA application on Kentucky bluegrass (Poa pratensis L.) responses to salinit...
