Creator:: Horneck, Donald Arthur
Abstract:: Grass seed production in Oregon's Willamette Valley traditionally relied on open field burning for straw residue disposal and nutrient recycling. Changes in residue management from open field burning to methods that remove straw coincided with rapidly declining K soil test values. A survey of grass seed fields showed that many...

Creator:: Orthel, Krista D.
Abstract:: Later maturing cultivars and increased ability to apply irrigation have led to inquiries by producers about proper irrigation management in tall fescue (Festuca arundinacea Schreb.) seed crops. The literature reveals little information about irrigation of perennial grass seed crops in general, and none about tall fescue in particular. Willamette Valley...

Abstract:: Hard white winter (HVVW) wheat cultivars must have superior protein quality and consistent processing quality to be successful in the Asian market. New cultivars and management strategies are needed to produce HVVW grain for both bread and noodle applications from diverse environments in the US Pacific Northwest (PNW). This study...

Abstract:: In order to properly utilize organic amendments as nitrogen sources, reliable methods to estimate plant-available nitrogen (PAN) are needed. The objectives of this study were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence (FNE) calculations, (2) examine the relationships between the C/N ratio, total...

Creator:: Wanjagi, Francis Ndung'u
Abstract:: In a series of greenhouse experiments, isolates representing serotypically distinct subpopulations of Rhizobium leguminosarum bv. trifolii recovered from root nodules of field-grown subclover Trifolium subterraneum cv. "Nangeela"), were evaluated for their symbiotic effectiveness potential, their effect on regrowth potential of subclover, and for their competitive abilities to form nodules. Isolates...
