Many cultivars of table grapes (Vitis sp.) are grown in Oregon's Willamette Valley, but with the availability of several new cultivars, it is important to compare their performance to well-established standards in this region. Commonly grown cultivars ("established": Canadice, Interlaken, Jupiter, Lakemont, Neptune, Reliance, and Remaily Seedless) along with new...
Canopy management is critical to successful winegrape production. Canopy management begins with vineyard design and includes decisions about soil, water, cover cropping, fertilization and weed control. Shoot thinning, leaf removal, hedging and crop thinning are also part of canopy management.
Vineyard design and management methods that create vine balance will help sustain productive yields, achieve desired fruit quality and maintain vine health. Different climates across Oregon will affect strategies for achieving vine balance, but the basic approach is the same everywhere.
Vineyard management strategies, including vineyard floor management and crop level management, can be used to influence vine vigor and fruit composition. Two studies were conducted to evaluate the impact of these practices on Pinot Noir in Oregon's Willamette Valley. Managing crop levels is common in cool climate vineyard production though...
