Emerging Export Markets For High Quality Alfalfa Hay, Tom Keene Feb 2018

Emerging Export Markets For High Quality Alfalfa Hay, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

The exporting of hay from country to country has been evolving for many years. When we look at today’s exports of American hay, we see that the majority of it takes place off the west coast.


Managing Frost Damaged Alfalfa Stands, Christopher D. Teutsch, Jimmy C. Henning, S. Ray Smith, Tom Keene, Matthew Dixon Feb 2018

Managing Frost Damaged Alfalfa Stands, Christopher D. Teutsch, Jimmy C. Henning, S. Ray Smith, Tom Keene, Matthew Dixon

Kentucky Alfalfa and Stored Forage Conference

Wide fluctuations in springtime temperature are common in Kentucky. Late freezing temperatures in the spring can cause damage to alfalfa depending on how far along it is in breaking dormancy. This publication provides information on the effect of low spring temperatures on both established and new alfalfa stands that have begun growth, as well as a method of predicting sensitivity to late frosts or freezes.


Harvesting Alfalfa For Quality, Garry D. Lacefield Feb 2018

Harvesting Alfalfa For Quality, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa can be harvested for hay, baleage, silage, greenchop or grazing. Our goal is to produce, harvest and market high yielding-high quality forage. Profitable alfalfa programs consist of four basic phases and each phase have a specific goal.


Integrated Management Of Alfalfa Diseases, Kiersten A. Wise Feb 2018

Integrated Management Of Alfalfa Diseases, Kiersten A. Wise

Kentucky Alfalfa and Stored Forage Conference

Alfalfa diseases can reduce forage quality and the longevity of alfalfa stands. Integrated management of diseases can minimize disease impact and improve forage stand and quality. There are several important pathogens that cause disease on alfalfa, and the occurrence of these diseases, as well as the severity of damage, depend on several factors, including the type of pathogen, the environment, and the level of resistance of the host to a particular disease. In addition, disease presence and severity are also influenced by agronomic practices, particularly sowing dates, cutting dates and frequency, and fertility programs.


An Integrated Pest Management Ipm Approach In Alfalfa Production Systems, Lee H. Townsend Feb 2018

An Integrated Pest Management Ipm Approach In Alfalfa Production Systems, Lee H. Townsend

Kentucky Alfalfa and Stored Forage Conference

Alfalfa lends itself to an integrated pest management (IPM) approach for alfalfa weevils and potato leafhoppers, the two key insect pests of the crop. Both species live in most alfalfa fields every summer. However, alfalfa can tolerate low levels of their feeding without costly yield or quality loss.


An Integrated Approach To Weed Control In Alfalfa Production Systems, Jonathan D. Green Feb 2018

An Integrated Approach To Weed Control In Alfalfa Production Systems, Jonathan D. Green

Kentucky Alfalfa and Stored Forage Conference

The importance of weed control in forage production should not be overlooked, especially when you consider the high investment associated with alfalfa and other legume forages. Weeds reduce forage yield by competing for water, sunlight, and nutrients. For example, yield obtained from the first cutting of alfalfa can be significantly reduced by a heavy infestation of common chickweed. In addition to yield losses, weeds can also lower forage quality, increase the incidence of disease and insect problems, cause premature stand loss, and create harvesting problems. Some weeds are unpalatable to livestock or, in some cases, may be poisonous.


Fertilizing High Producing Alfalfa Stands, Edwin L. Ritchey Feb 2018

Fertilizing High Producing Alfalfa Stands, Edwin L. Ritchey

Kentucky Alfalfa and Stored Forage Conference

There are no secrets for successfully producing a high quality alfalfa crop. Successful alfalfa production is a product of suitable site selection, proper fertility and pH management, good pest control, and favorable weather conditions throughout the season. This paper focuses on proper fertility and pH management practices.


Alfalfa Establishment: Getting Off To A Good Start!, Christopher D. Teutsch Feb 2018

Alfalfa Establishment: Getting Off To A Good Start!, Christopher D. Teutsch

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is a highly productive forage legume that is well adapted to transition zone states like Kentucky. It can be grazed, hayed, or ensiled. Once established and under good management, expected yields range from 5-7 tons per acre per year. High yields can only be obtained from a dense and vigorous alfalfa stand. The first step in obtaining such stands is establishment. The establishment phase of alfalfa production is critical since realization of returns from all other input costs is dependent upon having a good stand and it is expensive. It is important to remember that alfalfa establishment begins long …


Fine Tuning Varietal Selection For The Mid-South, S. Ray Smith Feb 2018

Fine Tuning Varietal Selection For The Mid-South, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

There are many new alfalfa varieties that have come on the market each year. In fact, it can be hard keeping up with all the developments. In the following pages I will overview most of the important traits that can be found in new varieties. These include Low Lignin, Roundup Ready®, potato leafhopper resistance, higher quality, resistance to new diseases, and more… Many times I am asked “Are new varieties really worth the cost?” The best way to answer that question is to consider work by Dr. Jimmy Henning where he summarized 24 location years of Kentucky alfalfa yield data …
