Description
Knotgrass(Paspalum distichum L.), one of native grasses grown wild in swamps of warmer region of Japan, has an attention as a forage crop adapted to lowland paddy fields. Surveys were conducted during 1982 to 1983 to investigate the production of Knotgrass pastures including Italian ryegrass established on a swamp in ldogawa Farm, Kunitomi,Miyazaki. In 1982, slurry alone was applied at a rate ofN ,P205, K20; 60, 60, 75 kg/lOa/year and in 1983, 15 kg urea/lOa(N: 7 .5 Kg/lOa) ware added after each harvest, six times a year. Fresh yields of Knotgrass and Italian ryegrass in 1982 were 7.06 kg and 5.22 kg/m2, respectively. However, yield of Knotgrass in 1983 reached as much as 13.31 kg/m2, compared with 6.75 kg/m2 of Italian ryegrass. Annual total yield of Knotgrass and Italian ryegrass in 1982 was 12.28 kg/m2, less than 20.06 kg/m2 in 1983, suggesting that both species, especially Knotgrass responded to fertilizer N. From these findings, under fertilized and intensive management, Knotgrass was suggested to be an adaptive and productive species for swamp pastures in warmer region.
