Spring irrigation management of tall fescue (Festuca arundinacea Schreb.) seed crops

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...

The effects of paclobutrazol and uniconazol on red clover seed production

Creator:: Silberstein, Thomas B.
Abstract:: Excessive growth by red clover, Trifolium pratense L., grown for seed interferes with maximum seed production and harvest in Oregon's Willamette Valley. This study was conducted during 1986 and 1987 on red clover cv. Kenland to determine if plant height and dry matter production could be inhibited and seed yields...

The influence of phosphatase-producing bacteria on phosphatase activity and available phosphorus in soil

Creator:: Nelson, Sheila J.
Resource Type:: Masters Thesis
Full Text:: g-1 soil. Samples inoculated with P. fluorescens Pf-5 had acid phosphatase activities 8 to 17 times

Preliminary investigation of artificial incubation of emu eggs, and alternative feeds and management techniques for emu chicks up to ten weeks of age

Creator:: Allen, Carol Ann
Abstract:: A preliminary study was conducted to establish baseline data for emu artificial egg incubation and emu chick growth and management. Three experiments examined factors affecting hatchability of emu eggs that occur prior to and during artificial incubation. Characteristics analyzed were egg storage duration, hen age, egg weight, egg index, shell...

The influence of induced host moisture stress on the growth and development of western spruce budworm and Armillaria ostoyae on grand fir seedlings

Creator:: Parks, Catherine G.
Abstract:: This greenhouse study evaluates the influence of separately and simultaneously imposed water stress, western spruce budworm (Choristorneura occidentalis Freeman) defoliation, and inoculation with the root pathogen, Armillaria ostoyae (Romagn.) Herink, on the growth and biochemical features of Abies .grandis (Dougl.) Lindi. Seedling biomass, plant moisture status, bud phenology, and allocation...

Estimating plant-available nitrogen release from manures, composts, and crop residues

Creator:: Gale, Eric S.
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...

Symbiotic characteristics of Rhizobium leguminosarum bv. trifolii recovered from nodules of field-grown Trifolium subterraneum L.

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...
