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...

Development of oven and Karl Fischer techniques for moisture testing of grass seeds

Creator:: Benjamin, Ethan
Abstract:: Seed moisture is a primary factor influencing seed quality during harvesting, storage, and marketing of grass seed. However, the Association of Official Seed Analysts' Rules for Testing Seeds do not contain methods for moisture testing. The oven methods in use by seed testing laboratories in the U.S. are diverse and...

Persistence and accumulation of clopyralid (3,6-dichloropicolinic acid) in soil

Creator:: Tanphiphat, Karin
Abstract:: Field studies were started at Hyslop Farm, Corvallis, Oregon in 1984 to determine the soil persistence of the herbicide clopyralid (3,6-dichloropicolinic acid) under cropping situations. The herbicide was sprayed on bare soil at the proposed use rate of 0.14 kg/ha in the spring and on the same plots at a...

Models of a four-species annual weed community : growth, competition, and community dynamics

Creator:: Roush, Mary Lynn
Abstract:: Models of weed communities aid in the development of weed management strategies and elucidate the processes and mechanisms that regulate plant populations and communities. A conceptual weed community model was developed to organize key regulatory life-history processes. Specific investigations focused on the processes of plant growth and competition, and relationships...

The effects of density and proportion on spring wheat and Lolium multiflorum Lam

Creator:: Concannon, Julie Ann
Abstract:: This thesis consists of four chapters. Literature is reviewed in Chapter 1. Chapter 2 describes an addition series experiment to determine the influence of species density and proportion on vegetative and reproductive yield of spring wheat and Lolium multiflorum. Chapter 3 consists of a growth analysis experiment to determine whether...

The population dynamics and growth of salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus)

Creator:: Maxwell, Bruce D.
Abstract:: Salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus) are clonal shrub species common to reforestation sites in the Oregon Coast Range. These species have economic importance, because they reduce conifer seedling growth and survival. A population modeling approach was used to facilitate study of the biology of these species and to...

A comparison of vegetation suppression and sod-seeding methods using perennial ryegrass in renovation of non-irrigated permament pastures in western Oregon

Creator:: Neumeister, John H.
Abstract:: Sod-seeding techniques offer graziers a convenient way to introduce superior grass cultivars into underproductive permanent pastures. Production loss and erosion are minimized. In conjunction with improved grazing management and fertilization, renovation can significantly improve yield and quality of pastures. Existent vegetation must be suppressed prior to introducing new cultivars. This...
