The purpose of this trial was to evaluate 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. Direct seeding is often impossible in early spring and emergence would be slow and erratic. Thus, the lines were seeded in an unheated glasshouse for later transplant. This is the second in a series of early cabbage trials.
Methods
Extremely high quality leeks are being produced on a small scale in the Willamette Valley with good yields. The crop is usually seeded in early spring, matures in autumn, and can be held through the winter for harvest the following spring. Very few varieties are grown commercially and the highest quality plants have been transplanted and grown in trench culture. The most lucrative market is the restaurant trade, which demands long, thick, blanched stems. Healthy foliage can also be used decoratively in presentation of restaurant dishes.
Introduction
Overwintered vegetables, seeded in late summer or early autumn for harvest the following spring, are important new alternative crops in the Willamette Valley. These crops offer a source of cash flow in the spring, present the opportunity for three crops in two years, and may be less expensive to grow because of reduced needs for insecticides and irrigation. Cauliflower, onions, and spinach have shown the most promise as overwintered crops.

Introduction
Tomato and muskmelon production in the Willamette Valley is limited by cool springs, a short growing season, and relatively cool nights, even during mid-summer. Cultural techniques to increase the mean air and soil temperature around plants, such as black plastic ground mulch, floating row covers, and tunnels, have hastened development and increased yield of both these crops.
