‘Grasslands Roa’ tall fescue: Herbage dry matter production and quality under mowing

Abstract
In pure swards at sites in 4 regions of New Zealand, Roa and S170 tall fescue (Festuca arundinacea Schreb.) established slower than Ariki ryegrass (Lolium × hybridum Hausskn). Ariki ryegrass was generally superior to tall fescue at sites where soil moisture levels were maintained throughout the year (because of even rainfall or heavier soils), whereas tall fescue was more productive in areas prone to long periods of moisture stress (summer drought and/or light soils) particularly over the summer-autumn period. Roa tall fescue was better than S170 under frequent cutting but similar under infrequent cutting. Herbage of Roa tall fescue had a higher acceptability to sheep than S170.
