The current survey form of grassland has not played its role in managing the grassland effectively because of the ambiguous questionnaire items and the absence of method and time of the investigation. Therefore, this study was conducted to clarify and add the items for effective of grassland management. The survey form of grassland was regulated in Article 16 of the Enforcement Rules of the Grassland Act (Survey on Grasslands Management Status, etc.). The five contents that needed improvement were the grassland owner, the survey timing and method of established grassland, grassland used livestock, grassland usage condition, and grassland grade. In the improved survey form of grassland, the grassland owner was changed to the grassland manager. In addition, 'Survey by each land' was added to the improved survey form in which the managers can survey each land. The dimension of each grassland establishment method was deleted in the grassland establishment time and method. In the livestock using grassland, the number of livestock and the area where livestock are used were added, and the number of other livestock was added, too. The grassland grade was decided as the combined score by three evaluation categories; grassland usage, the ratio of forage production in grassland and kinds of forage. The high, middle, and low grades were over 8, 6~7, and under 5 points in the combined score, respectively. The results show that the changed survey form of grassland can make grassland management more efficient by materializing the subject of grassland management and the survey terminology and methods.

A study was conducted to provide direct comparisons of the effect of variations in herbage use, grazing and social behaviour upon the flat, slope and forest grassland with a total 30 Korean Native Cattle and 5 Korean Native Goats under 4-year old grassland established by intensive sowing method in Daecheon. The results obtained are summarized as follows; 1. Relative intake index, dry matter intake per animal and dry matter digestibility by Korean Native Goats in flat, slope and forest grassland were 35.2%-462g-63.7%, 35.0%-459g-63.0% and 29.8%-391g-62.1%, respectively. 2. Grazing time by Korean Native Cattle was not different among the grassland types, but ruminating time was increased in slope grassland, whereas in forest grassland was decreased. Resting time was increased in forest grassland, whereas in slope grassland was decreased. Walking time was increased in flat grassland, but loafing time was increased in forest grassland. The number of rumination, chews per bolus and defecation number were decreased in forest grassland. The number of drinks, total drinking water and walking distance were increased in slope grassland. 3. Animal distance, occupied area per animal and sub group formation by Korean Native Cattle in flat, slope and forest grassland were $3.4m-11.9m^2-3.6head$, $3.56m-11.0m^2-3.7head$ and $3.70m-14.6m^2-3.4head$, respectively. The order of grazing movement was similar to the pear-shaped grazing formation, but the relations of dominance between first grazer and last grazer upon different grassland types was not clear.

목초생육이 왕성한 시기(spring flush기)에 있어서 방목용 초지의 지나친 성장은 제상이나 불식초 증가로 방목초의 섭취량이 저하하므로, 이 시기에 적절한 초지상태를 유지하여 방목초나 섭취량의 저하를 억제해야 한다. 본 연구에서는 spring flush기에 있어서 윤환방목에 의한 초지의 이용에 대하여 검토하였다.(중략)

충청남도 내 초지 가운데 68%가 황무지화(중앙일보, 91년 6월 8일), 강원도 횡성군 내 초지의 64%가 부실초지(강원일보, 91년 12월 14일), 강원도 평창군 내 초지 대리관리 증가(도민일보, 93년 7월 27일), 강원도 홍천군 내 부실초지의 대부분은 외지인 소유(도민일보, 93년 7월 28일)라는 기사를 각 신문이 게재하고 있다. 아마 정부기관의 조사료관련 부서가 없어지기 시작한 것도 이때부터인 것 같다. 농후사료는 물론 조사료까지도 전화 한 통으로 해결하던 양축가가 많았던 것도 불과 몇 개월 전의 일이다. (중략)

This study was conducted to find out the changes of the botanical composition, ecological behaviour and forage value of vegetation in abandoned hilly pasture, in Yeoju, Kyonggi Province from April, 1993 to October, 1996. This experiment was arranged as a vegetation survey(Pflanzenaufnahme) with two different pastures ((1) with forkcrane planed pasture and (2) forest pasture). After the abandoned management of pasture, wild grasses and shrubs of the botanical composition were gradually increased and pasture plants tended to decrease rapidly in the two different hilly pasture. In abandoned management of planed and forest pasture, moisture figure, reaction figure and nitrogen figure of the ecological behaviour were greatly decreased and also the forage value of standing crop was greatly decreased in three years (from 7.06 to 4.60 in planed pasture and from 6.81 to 4.38 in forest pasture). After abandon of two different hilly pastures, fresh weight of standing crops in flowering stage was greatly decreased 48.5~54.1% in three years than that of the vegetation at the pasture management.

This experiment was carried out to study the effects of different environmental conditions and cultivation techniques on productivity of grasslands in central and southern area of Korea on 2017 and 2018. Average dry matter yield of grasslands at 10 actual production sites was 7,496 kg/ha. that was ranged from 4,652 to 13,292 kg/ha with least significant difference(LSD) of 1,577kg/ha between grasslands (p<0.05) on 2017. Average dry matter yield of grasslands at 10 actual production sites was 7,914 kg/ha. that was ranged from 3,927 to 12,372 kg/ha with LSD of 1,577kg/ha between grasslands(p<0.05) on 2018. Dry matter(DM) yield of grasslands have positive correlation with soil fertility (p<0.01) but not correlated with rainfall and air temperature among cultivation environments. And also DM yield of grasslands have positive correlation with grassland management techniques(p<0.01). These results suggest that practices of grassland management techniques and improvement of soil fertility are more important than cultivation environments by climate change for increasing the DM yield of grassland in central and southern area of Korea.

The object of this experiment was to investigate the effect of mixture which consist of different seeding rates and species on dry matter yield and quality in Daejon area. The field trials were conducted from 2003 to 2005 at Chungnam National University in order to evaluate the dry matter yield and quality of different mixture. The experimental design includes three mixture types: Conventional mixtures, CM{orchardgrass(Potomac) 50% + tall fescue (Fawn)20% + Kentucky bluegrass(Kenblue) 20% + white clover(Regal) 10%}, red clover + mixtures, RM{orchardgrass(Potomac) 40% + tall fescue(Fawn) 20% + Kentucky bluegrass(Kenblue) 10% + red clover(Kenland) 30%) and Turf type grass + mixtures, TM {orchardgrass (Potomac) 50% + turf type grass (tall fescue, Millennium 20% + Kentucky bluegrass, Midnight 10% + perennial ryegrass, Palmer III 10%) + white clover(Regal) 10%}. The average DM yield for 2 years of red clover+mixture(11,656kg/ha) was higher than those of the other mixtures(p<0.05). The content of crude protein and dry manu digestibility were higher in red clover+mixture than in other mixtures(p<0.05). but, the content of fibrous compounds like as NDF, ADF, cellulose and lignin were lower in red clover+mixture than in other mixtures(p<0.05). The crude protein dry matter(CPDM) yield was higher in red clover + mixture(2,832kg/ha) than in conventional mixture(2,372kg/ha) and turf type + mixture(2,266kg/ha)(p<0.05). The digestible dry matter (DDM) yield was higher in red clover + mixture(8,881 kg/ha) than in conventional mixture(8,255kg/ha) and turf type + mixture(7,314kg/ha)(p<0.05). In botanical composition at last cutting time in 2005, conventional mixture were maintained orchardgrass 45%, tall fescue 22%, Kentucky bluegrass 5% and white clover 24%. Red clover + mixture were maintained orchardgrass 40%, tall fescue 22%, Kentucky bluegrass 4% and red clover 31%. turf type + mixture were orchardgrass 37%, tall fescue 23%, Kentucky bluegrass 6%, perennial ryegrass 8% and white clover 24%, respectively. As summary, DM yields and quality of mixture species and seeding rates were observed significant difference. The results of this experiment indicated that red clover + mixture was more effective in enhancing the DM yield and forage quality in Daejon area.
