This experiment was carried out to investigate the sowing amount of Bromus spp. per 10a. The results obtained were as follows; 1. Shoot length of Bromus spp. for 1st cutting was long in proportion with the increase of sowing amount of Bromus spp. However, shoot length of Bromus spp. for 2nd cutting did not recognize the difference by the increase of sowing amount of Bromus spp. 2. Yield of Bromus spp. for 1st cutting was generally increased in proportion with the increase of sowing amount. However, yield of Bromus spp. for 2nd cutting cannot found the difference by the increase of sowing amount of Bromus spp. 3. According to this experiment, it was found that 3㎏ for 10a was fit for the sowing amount of Bromus spp.
