Grazing Alfalfa — A Reality, John H. Wilson
Grazing Alfalfa — A Reality, John H. Wilson
Kentucky Alfalfa and Stored Forage Conference
Alfalfa offers an excellent opportunity to beef producers for receiving excellent performance. Exciting results have been seen for the past two years on the Thomas Farm (Registered Polled Hereford). A total of 1063 pounds of beef per acre produced this year, with similar results seen in 1986 - a total of 874 pounds of beef produced in 1986.
Weed Control In Alfalfa, Jonathan D. Green
Weed Control In Alfalfa, Jonathan D. Green
Kentucky Alfalfa and Stored Forage Conference
Since weeds which infest forages are harvested along with the alfalfa crop, total dry matter production does not necessarily increase with good weed control. However, controlling weeds which invade alfalfa improve the forage quality. In addition, maintaining good weed control may also prolong the productive life of the alfalfa stand.
If managed properly, established alfalfa stands can effectively prevent many annual and perennial weeds from becoming a major problem. Maintaining proper soil fertility, soil pH, and good soil drainage are some practices which help keep the alfalfa competitive against invading weeds. Other factors which put alfalfa under stress, such as …
Blister Beetles In Alfalfa, C. M. Christensen, Lee H. Townsend
Blister Beetles In Alfalfa, C. M. Christensen, Lee H. Townsend
Kentucky Alfalfa and Stored Forage Conference
Blister beetles are Iong cylindrical beetles that may be black, gray, yellow and brown striped, black with gray margins on the wing covers or black with a red head. These insects are usually found feeding in clusters on alfalfa. They can cause severe sickness and sometimes death when livestock especially horses eat the live or dead beetles. They are usually not found in alfalfa in mid-July and early August which translates to the third or fourth cutting. Blister beetles (black ones, gray margined ones, and yellow striped ones) were collected in very noticeable numbers in several central Kentucky alfalfa fields …
Alfalfa Establishment, Garry D. Lacefield
Alfalfa Establishment, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
Alfalfa "Queen of the Forage Crops" is the most important forage legume grown in the United States. It is grown over a wide range of soil and climatic conditions. Alfalfa has the highest yield potential and the highest feeding value of all adapted perennial forage legumes. It is a versatile crop which can be used for pasture, hay, silage, green-chop, soil improvements and soil conservation. As a result. of this crops many merits; especially yield, quality and versatile use, it can be used successfully in many animal feeding programs.
Soil And Fertility Considerations For Growing Alfalfa, Monroe Rasnake
Soil And Fertility Considerations For Growing Alfalfa, Monroe Rasnake
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is a widely adapted crop which is grown across the United states and in many other counties. However, it is very sensitive to many soil and fertility factors which can limit its productivity. It is important to understand these factors in order to be a successful alfalfa producer.

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 …

- 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.

Abatement Of Nitrate Pollution In Groundwater And Surface Runoff From Cropland Using Legume Cover Crops With No-Till Corn, M. Scott Smith, Jac J. Varco
KWRRI Research Reports
Agricultural practices can have a significant impact on water quality. The effects of leguminous winter cover crops on leaching of NO-3; from soil have been investigated in this project. Legume cover crops, by fixation of atmospheric N, can reduce the amount of fertilizer N required to produce summer grain crops. The methods initially used to evaluate cover crop effects on No; transport included suction probe lysimeters and measurement of NO-3; in soil samples collected to a depth of 90 cm. These measurements demonstrated extreme spatial variability in NO-3; distribution and water …
Marketing Kentucky Hay, J. Kenneth Evans
Marketing Kentucky Hay, J. Kenneth Evans
Kentucky Alfalfa and Stored Forage Conference
That more income is needed by Kentucky farmers is a well established and accepted fact. Although, the tobacco program appears to be yet viable, we have long needed to supplement the tobacco income with income from the remainder of the farm. I think this audience is also well aware of the potential· for producing hay in Kentucky, particularly alfalfa. Estimates in the University of Kentucky potential study indicate that we could have in this state two million acres of alfalfa with a projected potential income of a billion dollars a year generated for our farmers.
This potential income should not …

Optimum Utilization Of Alfalfa In Sheep Rations, G. L.M. Chappell
Kentucky Alfalfa and Stored Forage Conference
The unique qualities of alfalfa as a forage afford the progressive sheep producer many opportunities to develop efficient sheep feeding programs. As a grazed sward, as hay or silage, alfalfa can be utilized in a variety of ways. The following points should be considered in developing programs using alfalfa.
Maximizing Alfalfa Hay In Beef Feeding Programs, W. Roy Burris, Garry D. Lacefield
Maximizing Alfalfa Hay In Beef Feeding Programs, W. Roy Burris, Garry D. Lacefield
Kentucky Alfalfa and Stored Forage Conference
Beef cattle comprise the largest group of forage and hay users in Kentucky. Because of their ability to utilize large amounts of low quality roughage, they are sometimes relegated to that role exclusively. There are many instances in beef production when alfalfa hay can be utilized because of its high protein content. The value of alfalfa hay in a beef operation can be estimated by the protein and energy that it furnishes.
Maximizing Alfalfa In Dairy Feeding Programs, Dan O. Riddell
Maximizing Alfalfa In Dairy Feeding Programs, Dan O. Riddell
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is an excellent feed for dairy cows. When used properly, alfalfa can help cut cost of production and increase level of production. However, like everything else, the feeding of alfalfa needs to be managed to maximize efficient production. There are three key steps involved in maximizing alfalfa in a dairy feeding program. These are:
- harvest alfalfa at the proper stage of maturity
- know what the alfalfa contains and feed accordingly
- get the alfalfa to the cows that need it.

Reducing Hay Losses — From Standing Crop Through Storage, Michael Collins
Reducing Hay Losses — From Standing Crop Through Storage, Michael Collins
Kentucky Alfalfa and Stored Forage Conference
Alfalfa management for maximum economic productivity is quite complex. Many factors ranging from cultivar selection and establishment to storage and feeding must be considered. In some cases these factors, yield and quality of a particular cutting of forage for example, are negatively correlated. Following good establishment of an adapted cultivar, cutting management has important effects on forage yield, forage quality, stand persistence, weed encroachment and other important responses. Maturity stage at the time of cutting greatly affects quality. After cutting, hay curing, packaging and storage conditions also affect quality. Clearly, in order to achieve the optimum combination of yield and …

Herbicides For Alfalfa Weed Control, William W. Witt
Kentucky Alfalfa and Stored Forage Conference
Numerous herbicides are available for controlling weeds in pure or mixed stands of alfalfa. In addition, these herbicides can be applied at different times and stages of alfalfa growth -from prior to planting to actively growing alfalfa to dormant applications during the winter. To be confident of achieving the desired weed control, it is important to apply alfalfa herbicides at the proper growth stage and rate.
The following tables contain information pertinent to proper utilization of the herbicides to obtain maximum weed control.

Marketing Programs And Strategies, J. Kenneth Evans
Marketing Programs And Strategies, J. Kenneth Evans
Kentucky Alfalfa and Stored Forage Conference
Hay has never been widely perceived as a cash crop, therefore, it has historically accounted for a very small part of the total cash sales by farmers. It has been estimated that more than 90% of all hay baled in the state is retained on the producing farms. Most of that which is sold is transported very short distances and of course if one farmer in a community has a good hay year, all do. Organized marketing efforts have been minimal in both scope and successes. In 1978, efforts were initiated toward a more organized system of marketing Kentucky hay. …
The Economics Of Stand Life In The Production Of Alfalfa, W. Donald Shurley
The Economics Of Stand Life In The Production Of Alfalfa, W. Donald Shurley
Kentucky Alfalfa and Stored Forage Conference
Alfalfa is a crop which once established, can provide production of hay for several years thereafter. The productive years of the established crop are often referred to as the stand life. The life of an alfalfa stand is variable depending on many factors including variety grown, soil, weather conditions during the production period, insect and weed pressures, and of course the management skills of the producer in timely harvesting and other production jobs.
