This experiment was canied out to determine the effects of nitrogen (N) fertilization level (0, 70, 140, 280 and 420 k a a ) on the grass growth, dry matter (DM) production, numtive value, and botanical composition in reed canarygrass (Phalaris ancndinacea L.) pasture. \ulcornerhe cultivar used in this study was Palaton, and the grass was harvested at soiling-hay stage (3 times per year) in 1992 and 1993. As the N level was increased, the plant height, DM produdion, and crude protein (CP) content were significantly increased (P<0.05). When the N was applied at the levels of 0, 70, 140, 280, 420 kg, DM yields were 4,540, 5,316, 6,060, 7,923 and 9,960 kgha, and CP contents were 17.6, 17.4, 17.4, 18.4 and 19.8%, respectively. However, as the N level was increased, DM percentage, total digestible nutrients, and relative feed value were decreased, while the contents of neutral detergent fiber and acid detergent fiber, and bareland were continuously increased, particularly in the plot of N 420 kg fdzation. From the above results, it is suggested that reed canarygrass was one of the sensitive pasture grasses to N fertilizer, and the proper amount of N application was 280 kg/ha/yr for desirable production, nutritive value, and botanical composition in r e d conarygrass pasmre.
