Description

In perennial ryegrass (Lolium perenne L.) swards large numbers of new tillers are produced shortly after flowering. This high tiller appearance rate is balanced by a high death rate of tillers produced in early spring so that relatively little change in sward tiller numbers occurs (Colvill and Marshall, 1984, Korte, 1986). Tallowin (1982) showed, however, that differences in grazing management can affect the percentage of early spring tillers surviving, and so result in different tiller age profiles in the following summer. This paper reports the results of an investigation of the effects on tiller age profiles and subsequent pasture production, of different late-spring grazing managements.

Effects of Late Spring Grazing Management on Tiller Age Profiles and Summer Autumn Pasture Growth Rates in a Perennial Ryegrass (Lolium perenne L.) Sward
