The Effect of the Application Levels of Slurry and Urea on Productivity of Silage Corn

액상구비 및 요소의 시용수준이 Silage용 옥수수의 생산성에 미치는 영향

This experiment was conducted for the effects of application levels of slurry and urea on the production of silage corn. The result was as follows; 1. DM yield of silage corn was the highest in the 100kg/ha level of urea and 160kg/ha of slurry. 2. Crude protein content was increased with increasing slurry and urea. 3. Total N production was increased continuously with increasing slurry in the 100kg/ha of urea, however, it was not affected by 200kg of urea. 4. NDF content was not affected by an application levels of slurry and urea.
