Nutritional Value of Warm- and Cool-Season Grasses for Ruminants
… 4)orchardgrass (Dactylis glomerata L.). The warm-season grasses (bermudagrass and bluestem) were higher (P < .01) in fiber components than the cool-season grasses (tall fescue and orchardgrass). Bluestem was lower (P < .001) in CP, hemicellulose, and ash, and higher in NDF (P < .001), ADF (P < …

Growth analysis and regrowth potential of three cool season grasses in spring
… showed that there was no difference among the grasses in CGR when averaging all weekly samplings. The non-structural carbohydrates in the stubble generally showed an inverse relation with the CGR. There were differences in total LAI among grasses when averaging the weekly cuts. The regrowth in …

Phenotypic Plasticity of Native and Invasive Cool-Season Grasses in Response to Frequency of Moisture Availability
<p>Phenotypic plasticity, the ability of an individual to alter its growth in response to environmental conditions, is an attribute that is considered a likely invader attribute, as it provides the opportunity to expand its ecological niche breadth. Adaptive phenotypic plasticity can affect not …

Developing Techniques to Quantify Phenological Development of Smooth Brome (Bromus inermis Leyss.): Sampling Variability
Management of invasive grasses such as smooth brome (Bromus inermis Leyss.) and Kentucky bluegrass (Poa pratensis L.) is a critical issue for land managers in the Northern Great Plains. Recent surveys of US Fish and Wildlife Service (USFWS) grasslands revealed fragments of native prairie and …

Evaluation of Mixed-Vegetation Plantings As Avian Nesting Habitat in Eastern South Dakota
Mixtures of legumes and non-native cool-season grasses have long been planted as avian nesting cover on wildlife management units. However in the recent past, there has been a trend toward planting native warm-season grasses. In 2000, South Dakota Game, Fish and Parks (SDGFP) began planting …

Effects of Altered Growing Season Precipitation and Management History on Aboveground Biomass Production in Tallgrass and Mixed Grass Prairie of South Dakota
… prairies effects vegetative production for cool season and warm season plants. Ranchers and farmers livelihoods are dependent on adequate annual precipitation and vegetation for cattle production. Historically, in South Dakota drought has occurred in northern mixed grass prairie one out of …

Denitrification and organic carbon in a series of riparian buffers in the Bear Creek National Demonstration Watershed
… controlling factors were different under warm season grasses and introduced cool season grasses at different depths. Denitrification potential measured by the Denitrifier Enzyme Activity Assay (DEA), Total Organic Carbon (TOC), Total Nitrogen (TN), Dissolved Organic Carbon (DOC), Bioavailable …

Assessing the costs and benefits of native plant species for electric transmission line right-of-way revegetation within the Tennessee Valley Authority power service area
… on associated rights-of-way (ROWs). Native warm season grasses (NWSG) are more expensive for ROW revegetation compared to typical exotic cool season grasses (ECSG), but they may alter the successional trajectory such that long-term maintenance costs are reduced. I conducted a cost-benefit …

Biomass assessment in the U.S. midwest using MODIS time-series
… in the United States. Switchgrass, a type a Warm Season Grasses, has been regarded as alternative resources instead of annual crops for obtaining the bioenergy. The study is to delineate annual crops and perennial crops (Warm-Season Grasses and Cool-Season Grasses) in the U.S. Midwest based on …

Establishment of native plant species for livestock forage in silvopasture systems
… to: determine success of establishment of native cool and warm season grasses, and native forb and legume species in two different existing silvopasture systems -- pitch pine (Pinus rigida Mill.) x loblolly pine (Pinus taeda L.) hybrid and eastern American black walnut (Juglans nigra L.) -- with …

Yield and quality of cool-season perennial grasses for forage and biomass feedstocks in Northeast Colorado
… regions. Yield potentials are often lower for cool-season grasses, but for warm-season grasses like switchgrass difficult establishment and winter stand loss from extreme conditions can be a problem for production. There are many C3 species utilized in the Northeastern and the Western of the …

Lateral Movement of Herbicides on Golf Course Fairways and Effects on Bentgrass Greens
… herbicides recently registered for use in warm-season turf to control perennial ryegrass could be dislodged from treated areas and deposited on neighboring cool-season grasses. In a field study, rimsulfuron was applied at 17.5 or 35 g ai/ha to perennial ryegrass in the afternoon; the following …

Evaluation of alternative forage species to reduce risk for cow-calf production systems in the Appalachian region
… productivity is essential to reduce pasture seasonality and ensure available forage to meet the nutritional needs of livestock. This study explores the risk-buffering ability of warm-season forages to fill the summer slump gap in production of cool-season grasses. Small plot experiments were …

Analysis of the role of velvet and laeA in the molecular interactions between grass and Epichloë fungal symbionts
… agriculturally important symbioses with many cool season grasses. However, little is known about the molecular details of the interaction and the key regulatory systems involved. VelA and LaeA are two wellknown regulators of different fungal development and metabolic processes. Some of these …

Sprinkler system performance and irrigation scheduling effects on turfgrass quality
… (L.) Pers. (Common Bermudagrass). Data for cool season grasses were obtained from literature. The data were analyzed and a relationship between turfgrass quality and water application depth/evapotranspiration was developed for each turfgrass type. The results of the investigation show that …

Competitive Effects of Perennial Ryegrass and Chewings Fescue on Bermudagrass Seed Establishment
… and subtropical climates, where neither warm season nor cool season grasses are well adapted. The late-spring establishment of seeded bermudagrass could potentially enhance summer quality of a perennial ryegrass fairway during periods of extreme summer stress. Studies were conducted over two …

Avian Nesting Densities and Success in Introduced Cool-Season Grass-Legume Plantings Versus Warm-Season Native Grass Planting in South Dakota 2002-2003
… and idle grassland. Studies indicate that warm-season native grass plantings (WSN) generally provide good winter cover. Recently a trend favoring WSN has emerged, but limited information exists on nesting density and success of cool-season grass-legume plantings (dense nesting cover [DNC]) …

Modeling the Impacts of Rangeland Management Practices on Flow and Sediment Using SWAT
… Scenario 2 was performed using a mix of warm and cool season grasses to symbolize a range seeding BMP. Rangeland management BMPs were simulated by altering the runoff curve number to represent areas of poor, fair, and good ground cover. Implementation of stream BMPs, such as riparian zone …

Improved Strategies for Dollar Spot Suppression Using Ferrous Sulfate
… is one of the most common diseases of warm- and cool-season turfgrass stands and is especially devastating on creeping bentgrass (Agrostis stolonifera L.). The fungus Sclerotinia homoeocarpa degrades the foliage by creating silver, dollar-sized depressions of dead and bleached turf. Frequent …

Assessing Drift and Lateral Mobility of Flazasulfuron and Trifloxysulfuron Sodium
… weeds. In fine turf, flazasulfuron controls cool-season grasses such as tall fescue (Festuca arundinacea) and perennial ryegrass (Lolium perenne) without harming warm-season grasses. Although SU herbicides like flazasulfuron bring several potential benefits to turfgrass markets, there are …
