초록
This experiment was canied out to select the optimum utilization method by various pasture types at National Livestock Research Institute, Suwon in 1992 and 1993. Tne main plot was two pasture types. wfiich were mainly top-grass(orchardgrass dominated pasture) and mainly bottom-grass(perennial ryegrass dominated pasture), and the subplot was three pasture utilization methods (grazing, grazing after the 1st cutting, and alternate utilization of cutting and grazing). Average dry matter yields of pasture were not affected by pasture types, but there was significant difference(p <0.05) by pasture utilization methods. Daily DM production of pasture was increased with alternate utilization of cutting and grazing at two pasture types. Also, pasture availability is increased by mainly top grasses and alternate utilization of cutting and grazing. Soil phsical chracteristics are improved by alternate utilization of cutting and grazing. According to the results obtained from this experiment, it is suggested that alternate utilization of cutting and grazing is effective for dry matter yield, pasture availability and soil phsical characteristics regardless of pasture types in Korea.
