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

Marketing Quality Alfalfa Hay, Garry D. Lacefield
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
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
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
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
Grazing Options In Alfalfa Utilization, Paul D. Deaton
Kentucky Alfalfa and Stored Forage Conference
Objective
- The pure alfalfa stand would not be damaged during the grazing period.
- For steers - animal performance while on the alfalfa was more important than pounds of beef produced per acre.
- For cow/calf - animal density high enough to remove green leaf area in maximum of 5 days.
- Initiate the demonstration with a minimal out-of-pocket cost for fence, water system, etc.
- 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
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
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
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
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
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.

Evaluation Of New Pasture Legume Species In Terms Of Summer Feeding Value And Effects On Wool Production., S E. Flecker, C W. Thorn, J. B. Rowe, Tess Casson
Experimental Summaries - Plant Research
86KA71, Pasture legumes improve the feeding value of summer pastures in a mediterranean-type environment by maintaining the protein intake of grazing animals over the dry summer period, much of which comes from the ingestion of legume burr (A.D. Wilson and N.L. Hindley, 1968). Some of the most important species of pasture legumes to have been released commercially are Trifolium subterraneum (sub.clover), Medicago truncatula (barrel medic) and Medicago polymorpha (burr medic) (D.B. Purser, G.B. Taylor and W.J. Collins, 1987). What little information is available on the feeding value of these species suggests that barrel medic pod (H. Brownlee, 1973) and dry …

Trial 65SG5. Location - Paddock H5 on Salmon Gum Research Station
Cleared in 1962, then cropped until the start of the trial in 1968. Two of the four blocks were sown to Cyprus Barrel medic which is topdressed with superphosphate. The other two blocks regenerate volunteer pasture which is not topdressed. In 1984 all pasture plots were sown to SERENA medic. This grew exceptionally well in 1984 and set a lot of seed. In 1987 field peas were introduced into 4 reps of an existing medic: crop rotation.
Rates, Times And Sources Of Nitrogen On Wheat, J W. Bowden
Rates, Times And Sources Of Nitrogen On Wheat, J W. Bowden
Experimental Summaries - Plant Research
Trial 87WH51
Location: Wongan Hills Research Station.
This trial was put onto a site adjacent to Mel Mason's source of nitrogen trial and the CSIRO, 15 N plots to provide some explanation of the results from the limited treatments in those trials. They were designed to monitor soil/fertiliser nitrogen transformations with time. Unfortunately the site of this trial was variable. The end most similar to the other trials was deeper and sandier and stored less water than the other and where crop growth was far better.

Post Emergence Weed Control In Lupins., R. Madin, J. Buckley
Experimental Summaries - Plant Research
As a general assessment in can be said that Tigrex is a safe and efficient herbicide for control of radish in wheat. Brodal alone was generally unsatisfactory for radish control. While Diuron + Brodal was safe and efficient, Ally and Brodal should not be used together. Diuron + MCPA gave poorer control than one would normally expect.
