This study was carried out to determine the effects on the forage productivity when 5 different herbage species (orchardgrass, tall fescue, perennial ryegrass, redtop and ladino clover) were grown individually in pots with lime (0 or 300 ㎏/10a) and phosphate (0, 20, 40, 8O ㎏/10a) on black (B) and very dark brown (VDB) volcanic ash soil of Cheju island. plant height was taller in VDB than in B. I he lime application increased only the height of ladino clover, but phosphate application increased the height of all 5 species (p$lt;0.01). Dry matter (DM) yield of orchard-grass was not different between B and VDB. but was increased (p$lt;0.0l) by lime (23.63 vs 25.32 g/pot) and phosphate (4.38, 26.42. 31.01 and 36.08 g/pot for 0, 20, 40, and 80 ㎏/10a, respectively). DM yield of tall fescue was not different between the soil types but was increased by lime or phosphate application (p$lt;0.01). DM yield of perennial ryegrass was not influenced by the soil types or lime application but was increased by phosphate application (p$lt;0.01). DM yield of redtop was higher in VDB than B and was not influenced by lime application but was increased by phosphate application (p$lt;0.01). DM yield of ladino clover was higher in VDB than in B and was increased (p$lt;0.01) by lime (27.20 vs 21.33 g/pot) or phosphate application (1.62, 23.51, 30.86 and 41.08 g/pot for 0, 20. 40, and 80 ㎏/10a, respectively)
