Factors Affecting Seedling Emergence of Blackwell Switchgrass1
- E. B. Hudspeth and
- H. M. Taylor2
Switchgrass seedlings emerged from 3 ¼ inch depth of loose soil. However, when compaction pressure or surface slaking caused drying soil to develop considerable rigidity, emergence was hindered. With static medium to high available-moisture levels, pressures of 1 psi on loose soil caused significantly greater emergence than no pressure. Greatest emergence through a depth of ½ inch of loose soil occurred at about ⅓ atmosphere soil moisture tension.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
