  Citation × Citation Citation Abstract Copy Title: An Engineers Approach to Irrigation Management in Oregon Pinot noir Author: Selker, John, Baer, Emilie Vineyard managers must decide on the timing and amount of irrigation. In Oregon the need for irrigation differs greatly year to year and field to field based on micro climate, soil, root development, plant health, and root stock. We suggest the use of leaf water potential as a useful management tool. We show that for this test to provide consistent values, leaves should be wrapped prior to removal, should have consistent solar exposure, but need not have precisely the same age. We illustrate the use of this measure with data from the 2001 growing season taken in two Willamette valley fields. The data showed that irrigation was not required throughout the season, and helps explain the unexpectedly high yields noted by the vineyards.

  Citation × Citation Citation Abstract Copy Title: Manipulating Soil Moisture and Nitrogen Availability Part II: Effects on Pinot noir Must and Wine Composition Author: Watson, Barney, Godard, Mee, Chen, Hsiao-Ping The objectives of this study are to evaluate the effects of manipulating soil moisture and nitrogen availability using different approaches, including supplemental irrigation, nitrogen addition to the soil or to the leaves, and the elimination of competition for water and nutrients between the ground cover and the grapevines by tilling. The effects ofthese viticultural practices on juice and must composition, fermentable nitrogen content, fermentation behavior, wine composition, aroma, flavor, and wine quality are being conducted over several vintages at a mature commercial Pinot noir vineyard in the southern Willamette Valley of Oregon.

  Citation × Citation Citation Abstract Copy Title: Grass Cover Crops in Oregon Vineyards 1988 Author: Lombard, Porter, Doty, Jean, Price, Steve Perennial grass cover crops are frequently grown between the vines in non-irrigated Oregon vineyards. The primary reasons for using cover crops are erosion control and to allow machinery access in wet weather. Grass cover crops may also have an effect on vine performance. These effects, however, are not always clear. In addition, management options are available which can moderate or intensify the effect of a cover crop on the vines. At OSU, a research project was initiated to determine the effects of grass cover crops on grape vines. Our major concern was the degree of competition between the grass and the vines. In a vineyard with a sparse canopy and very poor growth, little or no competition is desired. However, in a vigorous vineyard with excessive vine growth, maximum competition could be desirable. The degree of competition is affected by several management options, such as choice of grass species and variety, width of the grass strip, and the year the grass strip is established. To better understand the relationships between grass and grapevine growth, our research concentrated on three areas: 1) vineyard establishment, 2) grass vs. no grass in mature vineyards, and 3) water use of different grass species.
