Abstract

ABSTRACTThis experiment was carried out to know adaptability and forage production and quality of sorghum,sorghum×sudangrass and sudangrass hybrids depend on drained condition at paddy field from 2007 to2008 at Chungnam province. Growth, forage production and quality of sorghum, sorghum×sudangrass andsudangrass hybrids showed more well drained condition than poorly drained condition at paddy field.Among growth characteristics, ‘SS405’ hybrids were somewhat strong for waterlogging, then and good atstem diameter, disease resistance. The dry yield of ‘SS405’ hybrid at poorly drained paddy field was thehighest as 12,938kg per ha. Fresh yield of poorly drained paddy field was 52.7% compared to that ofwell drained paddy field. The dry matter yield of poorly drained paddy field was the lower as 66.4% thanthat of well drained condition. ADF(acid detergent fiber), NDF(neutral detergent fiber), CP(crude protein)and IVDMD(in vitro dry matter digestibility) in poorly drained paddy field were 90.3%, 100.6%, 85.7%and 89.6% level compared to well drained paddy field.(Keywords: Sorghum, Sorghum×Sudangrass and Sudangrass Hybrids, Yield, Dry matter, TDN, Forage)
