Effects of Vegetation Structure and Plant Height When Grazed on Persistency of Meadow Fescue Pasture
Description
An intensive grazing technique using meadow fescue (Mf) pasture has been developed in northern Japan, where soil freezes in winter. It has been shown that the appropriate plant height of Mf pasture when grazed for persistency is about 27 cm. When Mf and perennial ryegrass (Pr) pastures were grazed at the same plant height of 20 cm, vegetation of Mf pasture declined and plant length of Mf pasture was longer than that of Pr pasture (Sudo et al., 2002). These phenomena might be due to the effects of differences in grass species and plant height when grazed on vegetation structure, but the mechanisms are not clear. This study was conducted to elucidate the mechanisms of these phenomena. Data on plant height and length obtained in previous studies were reviewed, and pot tests were carried out to reproduce the phenomena.
