Description
Lolium perenne L. (PRG) is one of the promising species in the northern Japan. However, this species is utilized less widely due to short persistency. The study was conducted to clarify the proper conditions for maintenance of this species in the context of defoliation treatments. The grasslands mixed with Dactylis glomerata L. (OG), Festuca arundinacea Schreb. (TF), Poa pratensis L. (KBG) and PRG were established and botanical composition of this mixture were measured in terms of Summed Dominance Ratio (SDR) under grazing (3 Japanese Black Cattle per ha) and cutting (3 times a year) conditions. PRG were maintained well under grazing conditions of 435-600 cow days/ha. In cutting conditions, however, PRG disappeared in the 5th year. This results suggested that competitive ability of PRG was higher under grazing than under cutting. And grazing intensity of 300-600 cow days/ha/yr is favorable for maintaining this species in the mixture.
