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...

Diagnostic approaches to evaluate nutrient status, partitioning, mineral dynamics, and relationships with yield and fruit quality of 'Valencia' orange trees

Creator:: Tami, Mohamed
Abstract:: Five nutritional aspects of 'Valencia' orange production in Agadir, Morocco during 1989-1991 were evaluated: 1) the effect of N and K on yield and fruit quality, 2) leaf sampling time and diagnostic approaches to optimize mineral nutrition, 3) mass and mineral partitioning within individual trees, 4) K-Rb relationships, and 5)...

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...

Nitrogen dynamics in field grown comice pears

Creator:: Sanchez, Enrique E.
Abstract:: The dynamics of N was studied in field grown Comice/Provence quince BA29 pears in Medford, Oregon. Total tree biomass, N content, and ¹⁵N evaluations suggest that young pears require little N (48 kg N ha⁻¹ yr⁻¹). About 45% of total tree N present in dormant trees was remobilized into new...

Economic and environmental evaluation of alternative farming systems for row crop and dairy farms in Northern Malheur County

Creator:: Vermilyea, Kathy Jo
Abstract:: Malheur County is located in the southeast corner of Oregon and consists of about 64 million acres of which 260,000 acres is irrigated. Groundwater contamination has been found in a 115,000 acre area in Northeastern Malheur County. The main source of the groundwater contamination is agricultural practices. The overall objective...

Chilling and nutritional requirements of fruit trees in Yemen

Creator:: Alkoshab, Othman
Abstract:: A portion of this study was initiated to provide the basis for implementing a chill unit accumulation procedure in Yemen. Most continuous or daily minimum, maximum temperature models severely underestimated chilling units, and slight modifications offered little improvement for the complex models. Only the Crossa Raynaud formula approximated generally accepted...

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...

The spectral backscattering properties of marine particles

Creator:: Whitmire, Amanda L.
Abstract:: The inherent and apparent optical properties of different ocean regimes are the basis for all optical remote sensing of the ocean. Ecological information derived from remote sensors therefore relies on having a detailed understanding of how particulate backscattering and absorption contribute to the bulk optical signal. The absorption characteristics of...

Abstract:: Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...
