다국어 초록 (Multilingual Abstract)

Orchardgrass, tall fescue, ladino clover, and alfalfa were sown on the plowed native grasslands of 600 to 900m altitude in the Mt. Chiri on September 10, 1970. Germinating date, winter survival ratio, plant length at each time of 5 successive cuttings, and the pasture yield through October, 1971 were observed. The soil properties of the fields were characterized as pH: 5.5 and loamy, and O.M. : 13.3%. The fertilizers such as N, P₂O_5, K₂O, lime, and borax were applied on the fields. And yield of native grasses, which were fertilized or not, was determined. 1. The germinating dates were ranged from September 19 to September 26 and were 2 to 3 days later on the upper lands. Tall fescue was germinated 2 to 4 days earlier than other pasture species and alfalfa was the latest germinating pasture species of them. 2. Orchardgrass showed the highest winter survival ratio (58.6 to 72.2%) and alfalfa showed the lowest (31.6 to 64.5%). The winter survival ratio of alfalfa and tall fescue decreased critically in the fields of 700 to 900 and 900m altitude, respectively. 3. The average plant length of 5 cuttings was ranged from 31.6 to 37.3 ㎝ in the 3 field locations. The shorter pasture grew in the higher altitude. The orchardgrass was longest in all the fields (45.0 to 58.2 ㎝). 4. Orchardgrass showed the most highest hay yield (719 to 825 ㎏/10a) and alfalfa showed the least (645 to 725 ㎏/10a). The native grasses showed the hay yield of 803 to 825㎏/10a in the non-fertilized plot and 877 to 829㎏/10a in the fertilized plot in the first year.
