  • Influence of cover crops on vine performance at two Willamette Valley vineyards

    Creator:
    Sweet, Rebecca Marie
    Abstract:
    It is estimated that 50-75% of Oregon vineyards cultivate at least every other alley in order to 1) reduce water stress 2) increase vineyard canopy temperatures and 3) increase nutrient availability. Because many vineyards are situated on steep hillsides, frequent tillage could result in increased soil erosion, decreased soil quality...

  • Cover crop effects on root rot of sweet corn and soil properties

    Creator:
    Miyazoe, Mikio
    Abstract:
    Root rot of sweet corn in western Oregon and Washington is a significant disease that can reduce yield of intolerant cultivars of processed sweet corn by fifty percent. Root rot is caused by a complex of soilborne organisms, including Drechslera sp., Phoma terrestris, and Pythium arrhenomanes. Processors have adopted tolerant...

  • Using rootstocks to manipulate vine physiological performance and mediate changes in fruit and wine composition

    Creator:
    Sampaio, Tiago Luís Barros
    Abstract:
    A rootstock trial was established in 1997 at the OSU Woodhall vineyard, located in the Southern Willamette Valley, which included two experiments. The first experiment was a factorial of four varieties grafted on to 9 rootstocks, and also as ungrafted vines (a split-plot design). The second experiment was a randomized...
