- ... Separate field trials were conducted in 2007 and 2008 to investigate the effects of increasing densities of common ragweed or common cocklebur on total yield and forage nutritive values in tall fescue pastures. Common ragweed densities ranged from 0 to 188 plants m⁻⁻², and common cocklebur densities ranged from 0 to 134 plants m⁻⁻². Total biomass yields (weeds plus tall fescue) were determined in ...

- ... Common cultivars of tall fescue [Schedonorus arundinaceus (Schreb.) Dumort = Lolium arundinaceum (Schreb.) Darbysh.] host a fungal endophyte that produces ergot alkaloids. These alkaloids are linked to fescue toxicosis, a serious livestock disorder in the United States. This study was conducted to determine how ergot alkaloid concentrations fluctuate throughout the growing season in tall fescue re ...
