Abstract
The objective of this study was to determine which mixture types are suitable for maintaining grazing pasture at alpine area. The mixtures types were evaluated by the botanical composition and dry matter (DM) of forage. The experiment was carried out on the grazing pasture at Daekwanryeong area (altitude ; 840m) from 1991 to 1993. Treatments were composed of seven mixture types made of both different components and amounts of sowing. The components of each mixture were Orchardgrass (OG), Tall fescue (TF), Timothy (TI). Kentucky bluegrass (KBG), Reed cannarygrass (RCG), Red clover (RC) and Ladino clove. (LC). The seeding .ate of OG, TF, TI, KBG and LC in control(C) was 18:9:8:3:2 kg/ha, respectively and those of treatments of T1 (OG:TF:KBG:LC), T2 (OG:TF:KBG:RC), T3 (OG:TI:KBG:LC), T4 (OG:TF:KBG:LC), T5 (OG:TI:KBG:LC) and T6 (OG:RCG:KBG:LC) were 24:8:2:2, 24:8:2:2, 26:8:2:2, 8:28:2:2, 5:24:2:2 and 8:26:2:2 kg/ha, in seeding rate. respectively. The plant heights of mixtures in 1991, 1992 and 1993 were 33, 37, and 33 cm on average of before and after grazing, respectively. The 12cm of stubble height was left after grazing during 3 years which can result in the reduction of forage intake and utilization. This result indicates the grazing period will be needed to adjust. The proportions of TI, OG, KBG and LC in mixtures were increased constantly, and the proportions of weeds and bare lands were little. The T5, in which the smaller amounts of seeds were sown, is considered as proper mixture type for Alpine pasture. The DM yield tended to increase with the increased grazing period, and the highest DM yield was occurred in 1993. No significant difference among treatments was observed for the DM yield, however the 75 was highest (9,344 kg/ha) in the DM yields which is $5.7\%$ greater than the C (8,840 kg/ha). This result indicates that T5 (OG:TI:KBG:LC : 8:24:2:2 kg/ha) is considered to be proper mixture type at alpine pasture considering the botanical composition and forage yield.
