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.

Twenty-two sweet corn cultivars were evaluated for resistance to natural infection by common smut. Four cultivars (Jubilee, Krispy King, Summer Sweet 610, and Supersweet Jubilee) have been included in all 12 years of these evaluations to gauge the relative severity of smut pressure over that time and in each trial season.
