Ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae)

Creator:: Campanella, Donald M.
Abstract:: A study consisting of three parts was undertaken to investigate how variation in species interactions, population genetic structure, epidemiological parameters, and plant breeding system may influence the ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae). Interactions between natural enemy species may modify their net effect on...

Reducing over-winter nitrogen loss

Creator:: Hart, John M., Horneck, Donald A., Sullivan, Dan M., and Christensen, Neil W.
Abstract:: Nitrogen can be lost when the quantity of available nitrogen exceeds crop demand or nitrogen availability is not in synchrony with crop demand. Either situation results in accumulation of available nitrogen, primarily in the nitrate form, at the end of the growing season. Over-winter nitrogen loss occurs primarily as nitrate-...

Genetic Analyses Provide Insight into the Early Ocean Stock Distribution and Survival of Juvenile Coho Salmon off the Coasts of Washington and Oregon

Creator:: Van Doornik, Donald M., Teel, David J., Kuligowski, David R., Morgan, Cheryl A., and Casillas, Emundo
Abstract:: Estimating the stock proportions of mixed-stock fishery samples by means of genetic stock identification has played an important role in the management of salmon fisheries. In addition, stock identification of individual fish has applications for population studies, forensic cases, and management issues. We examined 11 microsatellite DNA loci in 84...

Winter wheat in summer-fallow systems (low precipitation zone) [2007]

Creator:: Lutcher, L. K. (Lawrence K.), Horneck, Donald Arthur, Wysocki, Donald John, 1952-, Hart, John M. (John Mervyn), 1947-, Petrie, S. E., and Christensen, Neil Walter, 1944-
Abstract:: Recommendations in this fertilizer guide apply to tillage fallow-winter wheat and chemical fallow-winter wheat cropping systems. This guide is one of a set of publications that address the nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon. Recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc are covered...

Estimating nitrogen mineralization in organic potato production

Creator:: Oregon State University. Extension Service, Sullivan, Dan M. (Dan Matthew), 1954-, McQueen, John Paul Gainer, and Horneck, Donald Arthur
Abstract:: Potatoes require adequate nitrogen to produce quality tubers and high yields. Organic farming practices are designed to build soil nutrient levels gradually. In organic systems, nitrogen (N) enters the soil in the form of crop residue and amendments (e.g., manures, composts, and specialty products). Much of the N added to...

Acidifying soil for crop production : Inland Pacific Northwest

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, Horneck, Donald Arthur, Wysocki, Donald John, 1952-, Hopkins, Bryan G., Hart, John M. (John Mervyn), 1947-, Stevens, Robert G., and Pacific Northwest Cooperative Extension
Abstract:: This publication is a technical and practical guide for soil acidification in commercial fields. It explains the soil chemistry involved, how to determine whether pH adjustment is feasible, and methods for acidifying soil. This guide is divided into five sections: • Understanding soil pH • The problem—iron chlorosis • Causes...

Tall fescue grown for seed (western Oregon) [2005]

Creator:: Hart, John M. (John Mervyn), 1947-, Mellbye, Mark Edward, Horneck, Donald Arthur, Gingrich, Gale Allen, Young, William C., and Silberstein, T. B.
Abstract:: Tall fescue is grown for turf or forage seed on a broad range of soils in western Oregon. Typical seed yield is 1,200 to 2,000 lb/acre. Higher yields do not require additional nutrients beyond amounts recommended in this guide. These recommendations, especially for nitrogen, are adequate for production of more...
