  • Yield and quality of cereals for winter silage production

    Creator:
    Ben Ali, Mohamed Noureddine
    Abstract:
    A field study was conducted in 1978 and 1979 at two locations near Corvallis, Oregon, to determine the silage yield and quality of 13 fallsown cereal varieties at two nitrogen fertilizer levels in the context of a corn-winter cemal double cropping production system. Data on the yield, crude protein (CP)...

  • Whole farm case studies : a how-to guide

    Creator:
    Murray, Helene
    Abstract:
    Calls for increased farmer involvement in research and extension programs have been numerous and well supported. One approach to integrate the collective knowledge and experience of agricultural scientists and farmers is through whole farm case studies (WFCS). An interdisciplinary team of 34 research and extension personnel at Oregon and Washington...

  • Wheat genotypes selected under optimum conditions and their response to water and heat stress

    Creator:
    Briceno-Felix, Guillermo Ariel
    Abstract:
    Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

  • 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...

  • Water management effects on birdsfoot trefoil seed production

    Creator:
    García-Díaz, Carlos Alberto
    Abstract:
    There is no information available on water management of birdsfoot trefoil grown for seed. Information is also not available describing how to minimize seed losses due to shattering in order to obtain consistently high birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify crop water use,...

  • Water injection into the seed zone as an aid to emergence of dryland cereals

    Creator:
    Estes, James Patrick
    Abstract:
    An adequate stand at the optimum time is an important factor affecting potential yield and soil erosion control. However, obtaining adequate stands of fall planted winter wheat in the dryland areas of the Pacific Northwest is often complicated by marginal seed zone soil moisture. The purpose of this laboratory study...

  • Vernalization requirements and seed dormancy of jointed goatgrass (Aegilops cylindrica)

    Creator:
    Fandrich, Lynn
    Abstract:
    Jointed goatgrass (Aegilops cylindrica Host) infestations in winter wheat (Triticum aestivum L.) production regions of the central and western USA result in severe economic losses in the wheat market. Field and greenhouse studies were conducted to determine the vernalization requirements of winter wheat, spring wheat, jointed goatgrass, and wheat by...

  • Vernalization requirement studies with Pacific Northwest wheats

    Creator:
    Baloch, Dost M.
    Abstract:
    Vernalization plays a fundamental role in the adaptation of winter cereals to their growing environment by controlling their growth habit, thereby allowing them to escape cold injury. Because of the climatic conditions of the region, dry summers and wet winters, growers sometimes cannot plant all of their winter wheat in...

  • Use of combining ability estimates to identify the genetic potential of selected winter parental lines (Triticum aestivum L.em Thell)

    Creator:
    Masood, Muhammad Shahid
    Abstract:
    A major factor limiting the efficiency of plant improvement programs is the lack of knowledge as to which parental combinations to make when working with quantitatively inherited traits. The primary objective of this study was to provide information regarding the use of combining ability analysis to predict which cross combinations...
