| Abstract/Contents: | "Tall fescue (Festuca arundinacina Schreb.) is generally less productive, persistant, and competitive under stress after removal of its fungal endophyte, Neotyphodium coenophialum (Morgan-Jones & W. Gams) Glenn, Bacon & Hanlin (syn. Acremonium coenophialum Morgan-Jones & W. Gams). Our objectives were to compare endophyte-infected (E+) and endophyte-free (E-) tall fescue for (i) forage yield and tiller response at different cutting frequencies and heights and (ii) competition with no-till seeded alfalfa (Medicago sativa L.). Factorialized combinations of 3-wk and hay-stage harvest intervals with clipping heights of 3.8 cm (low) and 7.6 cm (high) were used with E+ and E- tall fescue in a 4-yr study. 'Alfagraze' alfalfa was no-till seeded into E+ and E- 'Kentucky 31' tall fescue, E- 'AU Triumph' tall fescue, orchardgrass (Dactylis glomerata L.), reed canarygrass (Phalaris arundinacea L.), and Kentucky bluegrass (Poa pratensis L.) in each year of 3 yr. Forage yield of E+ and E- Kentucky 31 was similar (P>0.05) within a cutting treatment. When cut at 3-wk intervals, a low as compared with a high clipping height had no effect (P>0.05) on total forage yield of E+ Kentucky 31 tall fescue, but forage yield of E- Kentucky 31 and E- AU Triumph were reduced by 23 and 28%, respectively, in the fourth year. Both E+ and E- tall fescue cut every 3 wk during a dry, hot summer at a low clipping height had autumn forage yields only 20 to 25% of that at a high clipping height. Tiller poplulations declined more on AU Triumph that E- Kentucky 31 in response to cutting. Cutting height had a minor effect on yield with hay-stage harvest. Endophyte infection had no effect on stands or forage yield of no-till seeded alfalfa. Alfalfa forage yields were lower with tall fescue than with the other grass species. AU Triumph, a winter-productive tall fescue, was the grass most competitive with alfalfa." |
