Effect of fertilizers on yield and quality of potatoes in the Willamette Valley

Creator:: Jackson, T. L. (Thomas Lloyd), 1922-, Sheets, W. A. (Willis Arden), Gardner, Ernest Hugh, Smith, R. L., Bullock, Richard M. (Richard Melvin), 1918-, McDermid, J. T. (Jack Thomas), Lighty, Willard, and Werth, H.
Abstract:: Data from fertilizer experiments with potatoes in the Willamette Valley from 1961 through 1971 show that responses have been measured from nitrogen, phosphorus, potassium, magnesium, and lime. Responses from these nutrients have been related to soil and/or plant analysis values. In recent years most of the potato production has moved...

Seed yield and yield components of Pennfine perennial ryegrass (Lolium perenne L.) as influenced by time and rate of spring nitrogen and chemical dwarfing

Creator:: Young, William C. (William Clyde)
Abstract:: Seed yield in perennial ryegrass is the product of yield components that develop during the life of the plant. Crop yield potential is defined by the number of fertile tillers, spikelets per spike, and florets per spikelet. It has been shown that perennial ryegrass realizes only a small percentage of...

Effect of pruning and training time on yield components and cold hardiness of 'Marion' blackberry

Creator:: Bell, Neil (Neil Charles), 1961-
Abstract:: The effect of primocane removal and training time on yield components and cold hardiness of 'Marion' trailing blackberry was studied. In 1991, primocanes were either not cut, or cut at ground level from plants on a single occasion at one month intervals from late April to late July. Four canes...

Producing fiber flax using modern machinery and field retting

Creator:: Kennedy, Ralph C.
Abstract:: Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in Oregon around 1957 before newly developed technology and fiber cultivars were available. The purpose of this research was to explore the use of modern methods and new cultivars. Field studies were conducted to evaluate cultivars and optimum cultural...

Residue management and yield characteristics of fine fescue seed crops

Creator:: Schumacher, Derek David
Abstract:: Chewings fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman] is a desired turfgrass with dense sod forming capabilities and superior shade tolerance. Thermal residue management (open-field burning) has traditionally been used to remove post-harvest residue and maintain seed yield over the life of the stand. However, alternative non-thermal residue management...

Applied nitrogen effects on yellow mustard (Sinapis alba L.) production in the Willamette Valley

Creator:: DuVal, Alyssa Susan
Abstract:: Nitrogen management recommendations for yellow mustard (Sinapis alba L.) production in the high rainfall environment of Oregon's Willamette Valley (WV) are not available. The objectives of this investigation were: (i) to determine the effect of applied nitrogen (N) on seed yield and yield components in yellow mustard, and (ii) to...

Trinexapac-ethyl and open-field burning in creeping red fescue (Festuca rubra L.) seed production in the Willamette Valley

Creator:: Zapiola, Maria Luz
Abstract:: Open-field burning has been an effective, economical, and widespread method of post-harvest residue management in creeping red fescue seed production in the Willamette Valley since the late 1940s. However, the use of field burning has been legislatively restricted due to air quality and safety issues. The foliar-applied plant growth regulator...

Methods to assess factors that influence grass seed yield

Creator:: Louhaichi, Mounir
Abstract:: A greater than 10-fold increase in Canada goose (Branta canadensis) populations over the past several years has resulted in concerns over grazing impacts on grass seed production in the mid-Willamette Valley, Oregon. This study was designed to develop methods to quantify and statistically analyze goose-grazing impacts on seed yields of...
