This study develops an improved method for understanding
economic production relationships in small scale
fisheries. This method postulates that gross revenue is a
function of physical input quantities, and is based upon
the transcendental logarithmic function to derive factor
share equations for each of the five inputs in the model....
Feedlot finishing of beef cattle in Southern Alberta involves
income risk due to the variability of prices of feeders, feed and
finished cattle. Several strategies are available to reduce this
risk, including hedging of cattle on feed, participation in a Federal-
Provincial government and producer established income stabilization
program for...
Competitive interactions between Douglas-fir seedlings (Pseudotsuga menziesii), and seedlings of a nitrogen-fixing hardwood
associate, red alder (Alnus rubra), were investigated in an addition series experiment. The primary objective of the research was to identify and quantify key processes underlying intra- and interspecific competitive interactions of Douglas-fir and red alder seedlings....
Effective chemical control of pollination would
provide an alternative to the cytoplasmic male-sterile
system in hybrid wheat (Triticum aestivum L.) production.
The objective of this study was to determine
concentration, formulation, growth stage of application
and genotypic effects on levels of induced pollen
suppression and subsequent natural out-crossing from
foliar...
A cost function characterizes a firm's cost-minimizing behavior. It is defined
as a function of the level of outputs produced and the prices of factors which enter
the production process. Econometric estimation of a cost function allows one to test
hypotheses regarding the structure of cost and the structure of...
Non-point agricultural contaminants, such as nitrogen, may lower groundwater quality and thereby impose health and environmental risks. The objective of this study is to evaluate tax policies to control agricultural pollutants in a spatially heterogeneous and dynamic setting. The focus of the study is non-point source nitrate contamination of groundwater...
In this work, we first introduce a novel approach to the long term irrigation scheduling
using Genetic Algorithms (GAs). We explore the effectiveness of GAs in the context of
optimizing nonlinear crop models and describe application requirements and implementation of
the technique. GAs were found to converge quickly to near-optimal...
Pre-harvest sprouting in wheat costs farmers millions of dollars every year. Pre-harvest sprouting tolerance (PST) has minimized this problem, but improvement of PST is still necessary. Synthetic hexaploid wheats (synthetics) have been used as sources of
genes coding for many useful traits. Two studies evaluated the PST of a synthetic...
Meadowfoam (Limnanthes alba Bentham; Order: Brassicales; Family: Limnanthaceae) is a self-compatible, predominantly allogamous, insect pollinated species. Meadowfoam oil is a source of novel unsaturated very-long-chain (VLC) seed oils (C₂₀ and C₂₂) with low concentrations of saturated fatty acids (typically less than 2%) and outstanding oxidative stability. Here we report the...
