Creator:: Oupadissakoon, Surapon
Abstract:: The influence of planting patterns and plant spacings on grain yield in field corn (Zea mays) was studied at the Oregon State University Botany and Plant Pathology Field Laboratory near Corvallis, Oregon in 1969. Plant characteristics and yield components studied included plant height, ear height, number of ears, ear weight...

Creator:: Clausnitzer, David
Abstract:: Medusahead (Taeniatherum caput-medusae ssp. asperum (Simk.) Melderis) is a Eurasian annual grass that infests large areas of U.S. rangelands, dominating former bunchgrass/shrub sites. Squirreltail (Elymus elymoides (Raf.) Swezey) is a native perennial grass that has demonstrated the ability to establish in stands of medusahead. A study conducted on two sites...

Creator:: Tiyayon, Chantalak
Abstract:: Morphology of Actinidia arguta (Sieb. et Zucc) Miq. 'Ananasnaya' vines was studied at two sites in Oregon in 1998 and one site in 1999. Three-year-old vines at site 1 and 8-year-old vines at site 2 were observed. Five types of fruiting wood were studied: spur; one-year-old from the cordon, from...

Creator:: Garrett, Amy
Abstract:: Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers. Predicting plant available...

Creator:: Taylor, Michael Monroe
Abstract:: Douglas-fir (Psudotsuga menziesii (Mirb.) Franco) seedlings were outplanted on eight dates (every three weeks from mid-August 2005 through mid-January 2006). On each plant date, seedlings from a conventional dormancy (CONV) induction treatment, including moisture and nutrient stress, and a shortened daylength (SD) treatment were outplanted on three western Oregon sites...
