An experiment was conducted to examine the responses to
selection for high and low rate of gain in the mouse under a system
whereby inbreeding was maximized. Rate of gain was measured by an
index designed to include gains in both the pre- and postweaning
periods with the gains in...
The effect of nitrogen (N) application on seed yield of Limnanthes
alba was studied for two years at two locations. Seeding following alfalfa
(Medicago sativa L.) was compared to establishment after wheat
(Triticum aestivum L.). Treatments used were a control (no N applied),
and two rates of N (50 and...
Dryland winter wheat in eastern Oregon is usually subjected to
water stress several times during the growing period. Moreover, the
last three months of growth period depend strongly on the available
soil water. The fertility level, stage of growth, availability of
soil water and climatic conditions all interact to determine...
Glucocorticoids are growth-inhibiting steroids. They have been reported to reduce
muscle growth by reducing protein synthesis. However, their actions on muscle protein
degradation remain equivocal. Glucocorticoids have been reported to transiently increase
muscle protein degradation, to not affect this process and to reduce muscle protein
degradation. Reasons for these conflicting...
Sod-seeding techniques offer graziers a convenient way to introduce superior grass cultivars into underproductive permanent pastures. Production loss and erosion are minimized. In conjunction with improved grazing management and fertilization, renovation can significantly improve yield and quality of pastures. Existent vegetation must be suppressed prior to introducing new cultivars. This...
An integrated framework of Family Resource Management and Household
Economic theory was utilized to develop a model of relationships between
human capital, family characteristics and resources, number of income
sources, hours spent in home production, total income and subjective well-being.
This study utilized a sample of 129 women systematically selected...
Four assumptions--
1. That there is an effective and potential demand for processed
fruit products in the Western State of Nigeria.
2. That current supply of raw materials in the Western State
of Nigeria is more than sufficient to meet the increased demand
which the short-term addition or expansion (or...
Much outdoor recreation occurs on publicly owned land and water
resources, or involves use of these public resources. Consequently, an
economic problem arises concerning the value of recreational resources
which do not have a conventional market price. Without a price to guide
the allocation of resources, it is difficult to...
Purple nutsedge [Cyperus rotundas L.) has been recognized as one of the
most troublesome perennial weeds of agricultural lands in tropical and some
temperate regions. This research sought to determine the effects of timing of
herbicides, shading, and soil moisture on plant population growth and tuber
production of purple nutsedge...
Changes in the structure of the U.S. agricultural
industry since World War II have transformed it into a
highly productive component of the domestic economy. But
these changes have not occurred without indirect costs. For
example, the reliance on agricultural chemicals has produced
environmental effects causing growing concern. In addition,...
