Description
Since summer growth of forage crops limits cattle grazing and hay production in Korea, it is important to exploit the natural resources which are suitable for forage production. A series of experiments to establish cultural management practice for Panicum dichotomiflorum MICHX. were carried out at the Experimental Farm of Chungbuk National University from 1993 to 1995. Stratification of seed promoted emergence and plant establishment. Although fresh and dry yield at the 1st harvest were closely related with number of plants established per unit area, total yield was less affected by number of plants at the early stage. P. dichotomiflorum MICHX. could be harvested 3 times beginning 40~50 days after planting and fresh and dry matter yields were 90~120 tons• ha -1 and 14~18 tons• ha -1, respectively. Fresh and dry matter yields were significantly influenced by growth duration. The optimum seeding rate was 15 kg• ha -1 when considering the 1st and 2nd harvest yields. Applications of nitrogen between 150kg•ha -1 and 300 kg•ha -1 did not affected fresh and dry matter yield significantly. Contents of crude protein, crude oil and crude ash were 16.3%, 20.0% and 11.5%, respectively.
