  • Effect of chlorpropham on vegetative and reproductive development in chewings fescue (Festuca rubra L. subsp. commutata Gaud.)

    Creator:
    Akobundu, I. O.
    Abstract:
    Experiments were conducted under field and greenhouse conditions to investigate the effects of chlorpropham (isopropyl mchlorocarbanilate) on vegetative and reproductive development in Chewings fescue (Festuca rubra L. subsp. commutata Gaud.) and to determine the time of induction and initiation under natural conditions. Chewings fescue was found to be very susceptible...

  • In vitro and in vivo evaluations of chemically treated ryegrass straw

    Creator:
    Anderson, Daniel Craig
    Abstract:
    Seven in vitro trials were conducted to compare the effects of soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH), potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM) was the criterion used to measure treatment response. A 3 x 3...

  • Effect of moisture stress on yield and quality of winter wheat seed

    Creator:
    Assuncao, Marcos Vinicius
    Abstract:
    Two experiments were conducted to determine the effects of moisture stress on physiological changes that occur during the vegetative and reproductive stages of the wheat (Triticum aestivum L.) plant, and to relate these effects to seed yield, quality and performance. In a field experiment, different levels of moisture stress were...

  • Relationships of clay mineralogy to landscape stability in Western Oregon

    Creator:
    Taskey, Ronald D. (Ronald David), 1944-
    Abstract:
    Soil erosion by mass wasting is the major problem on forest lands of the Pacific Northwest, The clay fractions of soils from a large number of sites in Oregon's Western Cascades were characterized in order to determine the relationships of various clay materials to mass movements. Each site was either...

  • Effect of production methods on quality of wheat seed

    Creator:
    Mathenge, Felix Njeruh
    Abstract:
    The objective of this research was to identify the optimum cultural practices for the production of the highest quality wheat seed in Oregon. The production methods included locations, irrigation, N levels and seeding rates. The seed quality factors studied were seed weight, bushel weight, protein content and seedling vigor. Foundation...
