Early macronutrient uptake and partitioning in Glycine max L. Merr

Creator:: Schuttler, Patti L.
Abstract:: Soybeans were grown in hydroponic solutions and in perlite to devise procedures to measure plant mineral accumulation and solution depletion over time. Electron emission spectrometry and micro-Kjeldahl-autoanalyzer analytic techniques were used to monitor mineral content of individual plants and their corresponding solutions. An automated computer assisted system of converting raw...

Influence of stocking density on grazing beef cattle performance, diet composition foraging efficiency, and diet quality on a late-spring early-summer native bunchgrass prairie

Creator:: Wyffels, Samuel A.
Abstract:: This study evaluated the influence of cattle stocking density on botanical composition of diet, diet preference, and cattle performance on the Zumwalt Prairie in Northeastern Oregon. In each of two years, 192 cow-calf pairs (549.27 kg, BCS = 4.89) and 48 yearling heifers (383.34 kg, BCS = 5.02) were stratified...

Digital analysis of remotely sensed images for evaluating color in turfgrass

Creator:: Friedkin, William C., 1954-
Abstract:: Most conventional approaches to rating turf color for different turf varieties grown under similar conditions or for the same variety grown under different cultural conditions employ a visual subjective rating. By digitizing remotely sensed images acquired by use of a helium filled blimp and a Canon EOS camera, we were...

Differences between mineral analyses from cork spotted and extra fancy 'Anjou' pear fruit

Creator:: Curtis, Daniel W.
Abstract:: The feasibility of using a post harvest sampling time for fruit testing in Anjou pears was evaluated. The goal was to determine if a simple and rapid analysis of fruit tissues could be useful in identifying potentially weak fruit that could be marketed before the onset of the storage disorder...

Effect of crop load on mineral uptake and partitioning in D'Anjou pears

Creator:: Meddouri, Messaoud
Abstract:: Three thinning levels were applied to twenty-five-year-old D'Anjou pear trees in a completely randomized design with five single-tree replicates on June 2, 1985. Samples of wood, shoot leaves, shoot twigs, spur leaves, spur twigs and fruits were taken every month during the season of growth for mineral analysis. Sampling an...

An evaluation of the Diagnosis and Recommendation Integrated System (DRIS) on hazelnuts (Corylus avellana) in Oregon

Creator:: Alkoshab, Othman
Abstract:: This study evaluates Beufil's Diagnosis and Recommendation Integrated System (DRIS) on hazelnuts. Although sufficiency ranges are currently the main approach for fertilizer recommendations in Oregon, DRIS enhanced nutritional interpretations, and might alter recommendations. Reference values (DRIS norms) were developed using 15 years of published and unpublished field data. DRIS indices...

Effects of forage quality and type of protein supplement on intake and digestibility in beef steers and performance of postpartum beef cows

Creator:: White, Jenny J.
Abstract:: Two experiments were conducted to evaluate the effects of forage quality and supplemental undegradable intake protein (UIP) level on intake, digestibility, and performance of beef cattle. In Exp. 1, five ruminally cannulated steers (BW = 456 ± 6 kg) were used in a 6 x 5 incomplete Latin square with...

Arthropod community structure in regenerating Douglas-fir and red alder forests : influences of geography, tree diversity and density

Creator:: Schaerer, Brett L.
Abstract:: The structuring of canopy arthropod communities was reviewed and investigated in relation to tree species diversity and its component factors, interspersion of different species and density of each tree species. Fifteen treatments of Douglas-fir (Pseudotsuga menziesii) and red alder (Alnus rubra) (various densities and proportions of each) were randomly assigned...

Factors influencing diet composition of beef cattle grazing mixed conifer mountain riparian areas

Creator:: Darambazar, Enkhjargal
Abstract:: Two trials were conducted to evaluate changes in the quantity, quality, and moisture of available forage in the pasture, and shrub utilization by cattle during a 30-d late summer grazing period (Trial 1) and the effect of cow age (experience) on grazing distribution and diet composition (Trial 2) in mountain...

Management of stockpiled forages and optimal use of supplements by beef cattle while consuming low-quality forages

Creator:: Suverly, Norman A.
Abstract:: Three studies were conducted to evaluate: 1) rotationally grazed forage for late-summer stockpiling; 2) effects of lactation on self-fed supplement intake; and 3) influence of cow age on hand-fed supplement intake. For the first study, treatments consisted of non grazed, 2X and 3X grazed. Crude protein of forage grazed 3X...
