However, the irrigation field experiments implemented in the 2010 season continued in 2011, in order to find out the impact of varied deficit irrigation regimes on vine development and fruit composition in Tempranillo and Cabernet Sauvignon cultivars.

• 2. [Article] Grass Cover Crops in Oregon Vineyards 1988

  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. ...

  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.

  Citation × Citation Citation Abstract Copy Title: The Effect of Cover Crops on Availability of Water to Grape Vines in the Willamette Valley in 1985 Author: Vomocil, James A. This study was initiated in its original form in 1982 with the Yamhill Soil and Water Conservation District and the McMinnville Field Office of the USDA-Soil Conservation Service. The Soils Department, Oregon State University, was one of several cooperators, in part funded by The Wine Advisory Board. In 1984 and again in 1985, water use by grapevines and by a few associated cover crops in each of three vineyards was measured using the neutron probe method. Access tubes are permanently installed at monitoring sites and the neutron probe is lowered into the tubes for measurements at various depths at weekly to ten-day intervals. Water use is calculated by the difference between the final and the initial soil profile water contents plus rainfall occurring during the measurement season. Cover crops are recommended for vineyards because they provide certain advantages, but there are also disadvantages, or possible hazards.
