Analysis of a hydrologic balance model and Penman-Monteith evapotranspiration estimating methods

Creator:: Carrijo, Osmar Alves
Abstract:: The major objectives of this study were an evaluation of the Meteorological Office Rainfall and Evaporation Calculation System (MORECS) evapotranspiration (ET) model using the Penman-Monteith equation and comparison of the MORECS and measured surface resistance. Meteorological, soil and plant parameters were measured in an alfalfa field over two growing seasons....

Full Text:: comparison of the MORECS and measured surface resistance. Meteorological, soil and plant parameters were

Physiological effects of water stress on young corn plants

Creator:: Barlow, Edward William Ross
Abstract:: Laboratory experiments were used to investigate the mechanism of plant response to water stress by determining the sensitivity of leaf elongation, photosynthesis and transpiration in young corn plants to a decrease in leaf water potential. In initial experiments, 9 day old corn plants were grown at soil water potentials of...

Comparative study of some soil characteristics of grassland and forest/grassland transition in western Oregon

Creator:: Ezenwa, Matthew Ikechuku Sunday
Abstract:: Vegetation as a soil-forming factor was studied under forest transition and grass while attempting to keep other soil forming factors constant in the western part of the Willamette Valley, Oregon. The physiographic units consist chiefly of the interior foothills and slopes formed from an old basaltic flow with some interspersed...

Seasonal distribution of forage production, N concentration, and Mo concentration in subterranean clover

Creator:: Petrie, S. E.
Resource Type:: Masters Thesis
Full Text:: fields with a recent Mo application by having plant samples taken in March and April analyzed. Decisions

Continuum mechanics methods applied to root growth and the penetration of soil by roots

Creator:: McCoy, Edward L.
Abstract:: The principles of continuum mechanics provide a consistent framework for the derivation of mathematical statements describing transport of water and solute, and growth in plant tissue. These derivations are based upon the explicit consideration of the tissue as a mathematical continuum composed of a cell wall matrix, water, and solute...

Some effects of sulfur fertilization on the nutrient value of subclover-grass forage

Creator:: McCarthy, Michael J.
Abstract:: Pastures consisting of mixtures of subclover (Trifolium subterraneum) and grasses have responded to sulfur fertilization on many sites in Douglas County, Oregon. The objectives of this study were to examine specific changes in forage quality which occur as sulfur is applied in excess of the amount required for maximum yield...
Resource Type:: Masters Thesis
Full Text:: excess of the amount required for maximum yield of dry matter. Plant samples and yield data were

Physiological and yield responses of snap beans (Phaseolus vulgaris) to water availability

Creator:: Biuk, Abdulmajid Ahmed
Resource Type:: Dissertation
Full Text:: , the observed turgor maintenance could not overcome the drastic effects of water deficit on plant

Translocation of photosynthates in soybeans (Glycine Max. (L) Merr. cv. Wilkin) as affected by soil water potential and soil temperature

Creator:: Ekasingh, Methi
Resource Type:: Dissertation
Full Text:: plant parts. At 24 hours, 14.8, 8.1 and 6.0 percent of total dpm/mg were in the tips at -0.35, -2.5

Leaf elongation as a function of soil water potential and photoperiod

Creator:: Hodges, T.
Abstract:: Leaf elongation is a major indicator of plant growth. It is controlled by complex interactions of many factors including light intensity, photoperiod, water availability, atmospheric conditions, and plant water stress. In this study, the response of leaf elongation to length of photoperiod and to plant water stress as indicated by...
