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...

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...

The influence of supplemental alfalfa quality on the intake and utilization of low-quality roughages by beef cattle

Creator:: Weder, Christoph E.
Abstract:: Three experiments were conducted to evaluate the influence of quality of supplemental alfalfa quality on beef cattle consuming low-quality meadow grass (MG) roughages. Fifteen steers (250 kg) were assigned randomly to one of three treatments: 1) meadow grass (5.2% CP), no supplement (MNS); 2) meadow grass plus high quality alfalfa...

Abstract:: A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...
