Effects of cork oak (Quercus suber L.) canopy cover on seasonal herbage production, foliar cover, and nutritive quality in the Mamora National Forest of Morocco

Creator:: Ibnattya, Abdelhai Andaloussi
Abstract:: This research was conducted in the Mamora National Forest of Morocco to: (1) Evaluate the effect of cork oak (Quercus suber L.) crown cover on seasonal herbage production, nutritive quality, and foliar cover on two distinctive sites in each of two years (1982, 1983) and to (2) assess the effects...

Evaluation of dry-weight-rank and microscopic point techniques for seasonal botanical analysis of two pasture mixtures

Creator:: Bauer, Welby
Abstract:: This study was undertaken to evaluate the dry-weight-rank and microscopic point methods for determining botanical composition on perennial ryegrass (Lolium perenne L.) - subclover (Trifolium subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) - subclover pasture mixtures throughout a grazing season. Botanical composition was determined on a monthly basis from...

The impact of grazing on forage quantity, quality and foliar cover of the herbaceous vegetation in the Mamora Cork Oak Forest, Morocco

Creator:: Mejjati-Alami, Mohammed
Abstract:: This research was conducted in the Mamora cork oak forest of Morocco to: (1) Describe the impacts of sheep grazing (none, 35% use, 70% use) in March, April, May and June of 1987 and 1988 on seasonal forage production; (2) evaluate the effects of these factors on annual changes in...

Assessment of a Douglas-fir/sheep silvopastoral system in western Oregon

Creator:: Lamouri, Abdelwahed
Abstract:: This research was designed to evaluate the effect of sheep grazing on Douglas-fir water potential, growth, and understory forage production in a small-scale silvopastoral agroforestry system, at Peavy arboretum approximately 13 km North of Corvallis, Oregon. Treatments examined included all possible combinations of two sheep grazing management treatments (grazed vs....

The role of costimulation and adjuvants in the development of T cell effector and memory responses

Creator:: Maxwell, Joseph R.
Abstract:: T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

Seasonal cattle and sheep diets on Festuca arundinacea-Trifolium subterraneum and Lolium perenne-Trifolium subterraneum pastures in western Oregon

Creator:: Bedell, Thomas E.
Abstract:: Sheep and cattle dietary preferences were determined on tall fescue-subclover ( Festuca arundinacea-Trifolium subterraneum) and perennial ryegrass-subclover (Lolium perenne-Trifoliuni subterraneum) pastures in western Oregon during the spring and summer periods of 1964 and 1965. Esophageal-fistulated Willamette ewes and Hereford and Hereford-Angus yearling cattle were grazed separately on each pasture mixture...

Tillering, lodging, dry matter partitioning, and seed yield in ryegrass (Lolium spp.) as affected by the plant growth regulator paclobutrazol

Creator:: Hunter, James L.
Abstract:: Seed yield in ryegrass (Lolium spp.) is the product of the number of fertile tillers per unit area and seed weight per spike at maturity. These components of yield develop through a series of growth stages beginning with tiller bud initiation and finishing with seed filling. Environmental conditions during plant...

Response of winter wheat (Triticum aestivum L. Em. Thell) to nitrogen and chloride fertilization in the presence of take-all root rot (Gaeumannomyces graminis var. tritici Walker)

Creator:: Maatougui, Mohamed El Hadi
Abstract:: Response from nitrogen and chloride fertilization was measured in field experiments on winter wheat (Triticum aestivum L. Em. Thell. var. 'Stephens' and 'Yamhill') grown in western Oregon in an environment with a range of susceptibility to take-all root rot (Gaumannomyces graminis var. tritici Walker). Cropping sequences and expected disease severity...
