NE-1020 Cold Hardy Wine Grape Cultivar Trial

In conjunction with the Northeast Regional Research project NE-1020 “Multi-state evaluation of wine grape cultivars and clones,” Iowa State University established a cold hardy wine grape cultivar trial in 2008 at the ISU Horticulture Research Station (HRS), Ames, Iowa, and Tabor Home Vineyards and Winery (THV), Baldwin, Iowa.

The Effects of Canopy Management Practices on Fruit Quality of Northern-Hardy Interspecific Hybrids of Vitisspp

The recent release of interspecific hybrid grape cultivars that are hardy for the northern climates of the United States has led to a rapid expansion of the grape and wine industry in the Upper Midwest, as well as other cold-climate regions. These cultivars often exhibit high vegetative vigor and possess fruit quality concerns when their grapes are to be used in wine production.

Effect of Living or Straw Mulch on Weed Management and Soil Quality in Grape Vineyards

The use of herbicides in vineyards has been a cost-effective means of in-row weed management under the grape canopy. However, as public concerns about issues such as pesticide run-off, ground water quality, and soil erosion have increased, grape growers have become aware of a need for alternative methods of weed management. The overall objective of this project was to identify optimal weed management practices that maximize grapevine growth and development as well as vineyard soil quality.

Cold Climate Cultivars

There has been interest in growing grapes in the upper Midwest and other cold climate regions of North America. One of the problems growers face in these regions is selecting cultivars (cultivated varieties) that will withstand severe winters, mature in short growing seasons, and be productive. As grape acreage increases in cold climate regions, too often cultivar selections are being made based upon testimonial or anecdotal information. With the high costs of vineyard establishment there is an increasing need for a standard reference to assist growers in selecting best adapted cultivars.
