Effect of organic residue and nitrogen levels on growth of spring wheat and ryegrass

Creator:: Panchaban, Santibhab
Abstract:: The vast area of sandy soils in Thailand which are low in fertility and can hardly hold water, prompted this investigation. A greenhouse study was conducted from December 1978 to April 1980 to find out the effect of straw on nitrogen availability that could affect dry matter yield and nitrogen...

Response of Marah oreganus to herbicides

Creator:: Flores, Maurilio
Abstract:: Marah oreganus, a perennial, belongs to the Cucurbitaceae family and it is commonly known as wild cucumber. In the past, this plant grew along fence rows, but now wild cucumber has become a weed problem in perennial grass seed fields of western Oregon. Several research studies were conducted to examine...

Pasture renovation with herbicide suppression of weeds and no-till seeding of orchardgrass

Creator:: Fitzsimmons, James P.
Abstract:: No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using...

Hare barley (Hordeum murinum ssp. leporinum) biology and management in cool season perennial grass pastures of western Oregon

Creator:: Haavisto, Jessica Lee
Abstract:: Hare barley (Hordeum murinum ssp. leporinum) is a cool season annual grass that invades pastures and range areas around the world. A documented weed management issue in several Oregon counties, hare barley may infest several thousand acres in western Oregon. This study was conducted to investigate the biology and develop...

Weed management for giant reed (Arindo donax) biomass production in Oregon

Creator:: Attarian, Amir
Abstract:: Giant reed (Arundo donax L.) is a candidate to provide feedstock for the Portland General Electric power plant in Boardman, Oregon. Giant reed is a fast perennial grass, producing 23-27 metric tons ha⁻¹ of biomass and has the ability to adapt to diverse environments making it a good candidate for...

Genetic factors that provide adult plant resistance against Puccinia striiformis f. sp. tritici to wheat cultivar 'Stephens' in a multilocation analysis.

Creator:: Vazquez, Maria Dolores
Abstract:: Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving increased attention in the USA since the appearance of more virulent races detected in the past decade. These races caused yield losses even in areas where the disease previously was rarely detected. Host plant resistance is the most cost effective...

Natural outcrossing in spaced planted F₂ populations and solid seeded advanced generations of wheat (Triticum aestivum L. em Thell)

Creator:: Boinnet, Jerry K. K.
Abstract:: This study was conducted to investigate the possible contamination of foreign pollen at different stages of a wheat breeding program. These included spaced planted F₂ segregating populations, replicated yield trials and seed multiplication. The experimental wheat materials consisted of four different F₂ populations, four cultivars and two experimental lines. Two...

Perennial Ryegrass (Lolium perenne L.) Cultivar Response to a Postemergence Application of Mesotrione

Creator:: Hinds-Cook, Barbara J.
Abstract:: Perennial ryegrass (Lolium perenne L.) is a widely grown cool season, bunch type, short lived perennial grass that is native to Europe, Asia, and North Africa, but has been adapted globally. Perennial ryegrass is quick to establish, has a long growing season, and produces high seed yield and forage or...
