Early Cabbage Variety Trial (1984)
February 1, 1985

Research report from OSU's North Willamette Agricultural Research and Extension Center

Delbert Hemphill and N. Mansour
OSU Dept of Horticulture, NWREC

The purpose of this trial was to evaluate several lines of cabbage for late spring or early summer harvest. This requires planting out in early spring and many varieties will bolt under these conditions. Since direct-seeding is often impractical in early spring and emergence would be slow and erratic, the lines were seeded in an unheated screenhouse and transplanted about six weeks later.
