It's as good as getting on the front cover of TIME magazine for Extension educators.

http://extension.unh.edu/news/home_cover.gifThe cover photo of the June issue of HortTechnology showcases vivid purple sprouts of winter sprouting broccoli ready for harvest in March in Durham.

Inside, a report by Becky Sideman, UNH Cooperative Extension associate professor/specialist, sustainable horticulture production, and Clifton Martin, plant pathology research associate, Ohio Agricultural Research and Development Center, shows that several purple and white sprouting broccoli cultivars can be overwintered in an unheated high tunnel for spring harvest in USDA Hardiness Zone 5 (Durham) sites.

According to their report, to determine broccoli's suitability as an early spring crop in the northeastern United States, 10 cultivars were grown in replicated experiments inside an unheated high tunnel over a two-year period in Durham.http://extension.unh.edu/news/F3.medium_001.gif

Results showed that the use of a secondary low tunnel covered with heavy row cover significantly increased winter survival, yields, and earliness of all cultivars.

The article also talks about location and climate, high tunnel environment and cultural practices, experimental designs and data collection and analysis.

The harvested portion of assorted cultivars of winter sprouting broccoli, showing shoots, florets, and attached leaves are shown in the photo to the right.
