Abstract

This experiment was carried out to know adaptability and forage production and quality of corn hybrid for silage at paddy field from 2007 to 2008 at Chungnam province. Growth, forage production and quality of silage corn showed more well drained condition than poorly drained condition at paddy field. Among growth characteristics, 'Kwangpyongok' and 'DK697' hybrids were somewhat strong for waterlogging, then and good at stay green, lodging, disease and insect resistance. Fresh yield of 'DK697' hybrid at poorly drained paddy field was the highest as 32,610 kg per ha among corn hybrids. The dry yield of 'P32P75' hybrid at poorly drained paddy field was the highest as 14,910 kg per ha The result of this study showed that 'P32P75', 'DK697', 'Kangdaok' and 'Kwangpyongok' hybrids had good growth characters and forage productivity at poorly drained paddy field and dry matter yield at poorly drained paddy field was 65.6% level compared with well drained paddy field.
