The experiment was carried out during 1955-1958, in Northern Kanto district. The purpose of this trial was to determine the effect of late cutting on the production of Orchard grass, Ladino clover and Red clover mixtures. They were submitted to the following treatments; with interval of 15 days between 3rd or 4th cuts, the time of cuttings were varied from 1 Oct. to 15 Dec. The results of this experiment are as follows: 1. It is suggested that the influence of late cuttings till the middle of Dec. is not significant to yields of next year. 2. In this year, the yields of dry matter tended to increase till the middle of Nov. and were maintained at the same level in the late of Nov. At that time, average temp. and min. average temp. pointed at 4-5℃, and 0-1℃ respectively. 3. Fluctuation of plant communities were examined, that was gradually increased Orchard grass, and decreased Ladino clover to the contrary, but the botanical compositions of next year were not signified between different cutting times.
