Rise To Power Of Senator Joseph R. Mccarthy: Reflections Of The Cold War Mccarthy Era In American Film, Scott Lainer

Honors Theses

The common bond between much of the film industry and Joseph McCarthy was insecurity and the drive for national approval. If one grasps the specific characteristics of McCarthy the man, and the methods of these politically "inspired" movies, we can to better place the period into context and acknowledge the fact that, if the citizenry is not aware, and is again caught by an ever-building wave of trickle down sentiment, the 1950s might not prove to be an isolated period in American history. Insecurity was not a fifties novelty. It still exists, and could potentially escalate anti-Communist policy and sentiment …

Disturbed Alpine Ecosystems: Seedling Establishment Of Early And Late Seral Dominant Species, Jeanne C. Chambers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the effects of seedbed and seedling environment on establishment of early and late seral dominant alpine species. Species studied included late seral dominant forbs (Geum rossii, Artemisia scopulorum, and Polemonium viscosum), early seral dominant forbs (Potentilla diversifolia and Sibbaldia procumbens), a late seral dominant grass (Festuca idahoensis), and early seral dominant grasses (Calamagrostis purpurascens and Deschampsia cespitosa). Germination responses of each species to wet vs. dry cold stratification and light vs. dark conditions were investigated. No statistical differences were observed in the seed germination of early and late …

Yield Accumulation, Leaf Area Index, And Light Interception Of Smooth Bromegrass, R. K. Engel, Lowell E. Moser, James L. Stubbendieck, S. R. Lowry

Department of Agronomy and Horticulture: Faculty Publications

Smooth bromegrass (Bromus inemis Leyss.) is a cool-season grass used extensively in the midwestern USA for spring and fall grazing. Smooth bromegrass has limited production in this region during the summer. This study was conducted to document the growth characteristics and yield accumulation of smooth bromegrass under various levels of N fertilizer. Live yield (dry matter yield of living herbage), leaf area index (LAI), light interception (LI), and crop growth rate (CGR) were determined on an established stand of 'Lincoln' smooth bromegrass grown on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic Argiudolls) in eastern Nebraska. Zero, medium, …

Marketing Quality Alfalfa Hay, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa hay is a potentially marketable-profitable product if--if quality is satisfactory to meet buyer's needs, if it is packaged such that it meets buyer's feeding program and can be transported efficiently, if in sufficient quantity, if storage site is accessible by truck or trailer, and if it is competitively priced. Meeting these minimum criteria only means the hay is potentially marketable; only after it has been sold does it become potentially profitable.

Feeding Alfalfa To South Carolina Dairy Herds, Fred E. Pardue, Terry Sudduth

Kentucky Alfalfa and Stored Forage Conference

The nutritional value of alfalfa hay is important if it is to be used competitively with other feedstuffs in rations being fed to South Carolina Dairy Herds. Excellent quality hay has high nutrient concentration, digestibility and intake. The appearance of good physical characteristics of alfalfa hay as well as other hays and forages along with the knowledge of harvest dates, stages of maturity, and other conditions are not enough and can be deceiving. Therefore, forage testing is crucial and very important.

Marketing Kentucky Hay — An Update, J. Kenneth Evans

Kentucky Alfalfa and Stored Forage Conference

Based on soil capabilities, Kentucky could grow 2-million acres of alfalfa while increasing the acreage of corn and soybeans. Even more than 2-million acres could be grown if Kentucky grown alfalfa should show market demands making it economically competitive with corn and soybeans. Marketing is the key to developing demand which could make hay a $1-billion Kentucky crop.

Many of you have heard or read my comments on marketing hay. In this presentation, I will present a brief review of what I have previously said and then bring you up to date on hay marketing activities since the alfalfa conference …

Evaluating Alfalfa Grazing — Dollars And Cents, Robert N. Barnes

Kentucky Alfalfa and Stored Forage Conference

Returns on many Kentucky farms are declining due to reduced tobacco and feedgrain income. This fact, coupled with traditionally low (or negative) returns from typical cow/calf beef enterprises, has been associated with interest in alternative crop and livestock production systems. Alfalfa produced as a cash crop is increasing and many farmers are realizing substantial returns. In the Central Kentucky Area, many farmers have been stimulated to produce alfalfa since demand for high quality hay by horse farms has been strong. As interest in alfalfa is renewed, other farms have begun to introduce intensive or controlled grazing techniques in order to …

Grazing Options In Alfalfa Utilization, Paul D. Deaton

Kentucky Alfalfa and Stored Forage Conference

Objective

1. The pure alfalfa stand would not be damaged during the grazing period.
2. For steers - animal performance while on the alfalfa was more important than pounds of beef produced per acre.
3. For cow/calf - animal density high enough to remove green leaf area in maximum of 5 days.
4. Initiate the demonstration with a minimal out-of-pocket cost for fence, water system, etc.
5. Minimize the occurrence of bloat where possible.

Comparison Of Electrical Moisture Meters For Baled Alfalfa Hay, W. H. Henson Jr., G. M. Turner, Michael Collins, O. J. Yeoman

Kentucky Alfalfa and Stored Forage Conference

A primary concern in producing quality alfalfa hay is moisture measurement. Some precision in moisture measurement is required since hay can be too wet, leading to dry matter and quality loss through mold; it can be too dry, leading to shatter loss during baling, handling and storage.

Moisture measurement in hay can take many forms. One form of subjective (personal judgment) evaluation is brittleness of leaves and stems in the windrow or bale. Typical objective methods consist of electric meters with calibration curves and oven drying.

Advances In Alfalfa Weed Control, James R. Martin

Kentucky Alfalfa and Stored Forage Conference

The most significant advances in weed control in alfalfa have originated from developments in herbicide technology, This method of weed control began over 20 years ago when such herbicides as EPTC and 2,4-DB were being used by alfalfa farmers. Since then, more than twelve herbicides have been added to the list of products recommended for weed control in alfalfa. (For specific recommendations, see Extension publication "Chemical Control of Weeds in Kentucky Farm Crops", AGR-6).

Influence Of Potato Leafhopper On Alfalfa Yield And Quality, C. M. Christensen

Kentucky Alfalfa and Stored Forage Conference

The potato leafhopper has the distinction of being one of the native insects that can have a very major impact on the production characteristics of alfalfa. This insect is very definitely the second most important pest of this crop, with the alfalfa weevil, an imported insect, holding the distinction of being the most damaging. These tiny insects (full grown potato leafhoppers are 1/8 inch long) have a very definite impact on alfalfa but their damage is very insidious and hard to recognize.

Quality Seed Production And Use, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Quality seed is an important consideration and investment in an efficient alfalfa program. Farmers who depend on alfalfa need to be certain that the seed they purchase is of high quality. High quality seed means it must be free of noxious weeds, have a purity of 99.5 percent, a germination of approximately 90 percent or higher and be seed that is true to the variety stated.

Effects Of Soils And Fertility On Alfalfa Production, Monroe Rasnake

Kentucky Alfalfa and Stored Forage Conference

Alfalfa can be grown anywhere in Kentucky and on a wide range of soil types. This statement seems to contrast with what we are accustomed to hearing in regard to alfalfa. The usual statement is: "Alfalfa requires a deep, well drained and highly fertile soil . . .". Actually, the two statements are not conflicting. They just represent the plant-soil interactions. The first looks at what is possible while the other is concerned with the ideal situation. In order to understand these different perspectives, we need to consider how soil characteristics affect the alfalfa plant.

Control Of Peas And Lupins In Wheat, J. R. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

Trial 87A29

Lupins were easier to kill than peas.

Glean applied pre-sowing gave very poor control of both peas and lupins.

The treatment using higher rates of 2,4-D amine in diuron mix also caused lower yields.

The Tordon 242 treatment appeared to cause some yield depression.

Effect Of Different Chemical Treatments On Capeweed Control And Crop Yield., J. R. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

Trial 87WH60

Control of capweed was obtained using post-emergence in-crop herbicides. Good control was on most of the treatments applied before seeding.

Most products showed good ryegrass control are not usually effective, assume some other factor operating. Treatment usually associated with good ryegrass control have higher ryegrass densities than the treatments using herbicides with only broadleaved variety.

Although large reductions in density of silvergrass were obtained none was significantly better than the unsprayed. Some treatments particularly those favouring grass dominance allowed silvergrass density to build up.

Bromegrass appears to be very sensitive to competition from capeweed. Where there was high …

Control Of Peas And Lupins In Oats, J. R. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

Trial 87A30

All lupin treatments satisfactory.

Treaments 4, 8 and 9, ie Dicamba 500 ml and both treatments with diuron + 2,4-D amine would not control peas sufficiently to prevent rejection of line of oats. Peas are more difficult to control.

Saffrom Thistle, Seed Set Control, J. R. Peirce, B. J. Rayner

Experimental Summaries - Plant Research

Trial 87ME119 - Saffron thistle, seed set control.

Trial 87TS38 - Saffron thistle control (seed set)

Trial 87JE42 - Seed set control in Saffron thistle.

All treatments had some measure of reducing seed production. Best control was obtained by applying chemicals just at or prior to flowering.

Control Of Wild Statice (Limonium Sinuatum) In Pasture., B. Kimber, R. Ramm

Experimental Summaries - Plant Research

Trial 87LG64

Wild Statice is a prolific seeder. Glean + diuron treatments, which were not included in trial gave good control, as did the farmer's treatment using Tribunil followed by heavy grazing. Later applications may be more effective because they may prevent seed formation for that year and also prevent the plant from recovering from spraying, as apparently with the early spraying.

Most chemical treatments would cause damage to broadleaved pasture.

Topsoil Displacement Methods For Crop Establishment. (Wheat And Barley), J. H. Moore, G. R. Dean

Experimental Summaries - Plant Research

The Tolerance Of Legumes To Broadleaf Herbicides., P. Stewart, L. Mann

Experimental Summaries - Plant Research

Trial 87KA52

The control of broadleaf weeds in leguminous pasture is of major concern because of the ability of these weeds to compete strongly with the leguminous plants. The presence of broadleaf weeds in pasture reduces the pastures nutritional value as well as total nitrogen fixation. There are many herbicides which are available to control broadleaf weeds, but most of these are registered for use in cereals. The amount of tolerance that leguminous pasture plants show to many of these herbicides and herbicide mixes is not known.

The experiments were designed to screen a large number of herbicides for legume …

Phenological And Reproductive Development Of The Four Major Grass Species, P. Stewart, L. Mann

Experimental Summaries - Plant Research

Trial 87KA51

The decision of when to spray is one of the major difficulties encountered when spraytopping grassy pasture for seed set control. Previous work has shown the general herbicide application timing window for the major grasses, but within this window, the amount of seed set control achieved can still be poor. Obviously timing within this window needs to be more rigorously defined. The fundamental question we need to answer is; when do the target grasses begin to produce viable seed in relation to their phenological development and in relation to other grass species? If we know this, then herbicide …

Effects Of Residue Levels Of Simazine On Wheat Growth, And Possible Synergism By Glean., Terry Piper, Patrick Pigott

Experimental Summaries - Plant Research
