Incinerated sewage sludge use as a soil amendment for sweet corn (Zea mays L.)

Creator:: Mellbye, Mark Edward
Abstract:: Field and greenhouse experiments were conducted to determine the suitability of using incinerated sewage sludge ash as a soil amendment for sweet corn production on Willamette silt loam. In 1977, field plots were treated with 0, 11, 22, and 43 mt/ha of ash containing lime, in factorial combination with a...

Improvement of biological control agents : laboratory selection for fast larval development in the convergent lady beetle, Hippodamia convergens guerin-Méneville (Coleoptera: Coccinellidae)

Creator:: Rodriguez-Saona, Cesar Ramiro
Abstract:: Hippodamia convergens Guerin-Meneville was selected for rapid development through five generations at four constant temperatures (18, 22, 26, and 30°C). Two levels of selection were used: intense and moderate. Differences in developmental rate, survivorship, live adult weight, aphid consumption, adult longevity, and fecundity were measured for both groups and an...

The simultaneous expression of metal tolerance and antibiotic resistance by bacteria from drinking water systems

Creator:: Calomiris, Jon James
Abstract:: Previous studies of six Oregon public water supply systems revealed that greater proportions of the standard plate count (SPC) bacteria from distribution waters were multiple antibiotic resistant (MAR) compared to isolates from the corresponding source raw waters. In the present study, two of these water systems were examined further to...

The Ecology and Epidemiology of Xanthomonas hortorum pv. carotae in Central Oregon Carrot Seed Production Systems

Creator:: Baldino, Katelyn D.
Abstract:: Xanthomonas hortorum pv. carotae (Xhc) is an epiphytic, plant pathogenic bacterium that causes the disease bacterial blight of carrot (Daucus carota subsp. sativus). Infection with Xhc can result in blighting of leaves and umbels and reduce quality and yield of carrot seed crops. Carrot production in the United States approaches...

Creator:: Chapman, Shannen S.
Abstract:: The Greenbelt Land Trust (GLT) (a grass-roots conservation group in Oregon) is interested in a conservation plan for the Marys River Corridor. To facilitate this effort, a resource inventory was required and a Geographic Information System (GIS) data base used to compile the inventory (called the Marys River Project (MRP))....
