Advances In Alfalfa Promotion, Bill Talley

Kentucky Alfalfa and Stored Forage Conference

Kentucky grain farmers have experienced several successful years seeing high prices and good yields, with the exception of the drought in 2012. If you were insured in 2012, which most lenders required, you probably also came out with a profit during that challenging time. Alfalfa producers in Kentucky have also seen high prices and decent yields. While the drought of 2012 affected them, most still harvested an 80 % crop with extremely high prices and demand. The fact that alfalfa is a deep rooted plant, coupled with timely rains proved beneficial to this group.

Why Aren't Big Square Balers Used More In Kentucky?, Tom Keene

Kentucky Alfalfa and Stored Forage Conference

The history of making hay dates back for centuries and centuries. When mankind began to grow crops and livestock rather than being nomadic, they had to have some type of forage to feed their livestock during the cold and winter months. Since that time there has been a slow and steady progression from harvesting material by hand to today’s modern hay making equipment that maximizes time, labor, fuel, etc. However some countries to this day still use the methods that are thousands of years old when it comes to hay making.

Alfalfa For Summer Grazing, Roy Burris, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is most commonly used as a hay crop in the United States. However, with proper management, it can be utilized as a grazing crop with very good results. Liveweight gains per acre are quite high for grazing beef cattle with total season grains of 500 to 800 pounds per acre being reasonable. The authors realized 732 lb/acre of gains on 16 acres of alfalfa in 1991, with beef steers at Princeton.

Lessons Learned In Australia--Uk Forages Study Tour, Traci Missun, S. Ray Smith, Garry D. Lacefield

Kentucky Alfalfa and Stored Forage Conference

In September 2013, twenty Kentuckians traveled to Australia to tour farms and attend the International Grasslands Congress. The group included ten county agents, five farmers, four UK faculty/staff and a teacher. This study tour allowed participants to gain a new perspective of agriculture and how Australian farmers deal with adversity. Farmers there face many challenges each year with change in precipitation, ranging from severe drought to flooding. These challenges have forced them to incorporate different methods to be successful, including intensive grazing, use of overhead and drip irrigation for pasture and hay production, and fallow farming.

Alfalfa Baleage/Silage Preservatives: Do They Work? Are They Economical?, S. Ray Smith

Kentucky Alfalfa and Stored Forage Conference

There are many variables with silage production including - type of silage operation (silo, bunk, tube, or wrapped bale), weather, packing or bale density, speed of covering. Therefore, no two silage crops are ever the same, which is why researchers are reluctant to give blanket statements regarding when and how to use silage inoculants. There has been a lot of good research though in recent years about the effect of silage inoculants under various management and conditions. What follows is an overview of this research and some general recommendations. Much of this overview was taken from a very good fact …

Role And Importance Of Alfalfa In Wku Teaching/Research/Farm Programs, Elmer Gray

Kentucky Alfalfa and Stored Forage Conference

Alfalfa is the oldest and most widely grown forage legume in the world and in Kentucky, where approximately 250,000 acres are produced. It has gained this top position through producing forage suitable for most classes of livestock, by being drought tolerant, and by fixing atmosphere nitrogen.

Warming, Soil Moisture, And Loss Of Snow Increase Bromus Tectorum’S Population Growth Rate, Aldo Compagnoni, Peter B. Adler

Green Canyon Environmental Research Area, Logan Utah

Climate change threatens to exacerbate the impacts of invasive species. In temperate ecosystems, direct effects of warming may be compounded by dramatic reductions in winter snow cover. Cheatgrass (Bromus tectorum) is arguably the most destructive biological invader in basins of the North American Intermountain West, and warming could increase its performance through direct effects on demographic rates or through indirect effects mediated by loss of snow. We conducted a two-year experimental manipulation of temperature and snow pack to test whether 1) warming increases cheatgrass population growth rate and 2) reduced snow cover contributes to cheatgrass’ positive response to …

Limitations And Benefits To Cultivating Tobacco, Edwin L. Ritchey, Gary K. Palmer

Plant and Soil Sciences Research Report

Historically, between-row cultivation for weed control has been an integral part of tobacco production. In one season, a grower might perform five or more cultivations and several hand weeding operations for adequate weed control. Early herbicide chemistries would control some weeds, but not all, forcing the producer to cultivate and hand weed. The development of better herbicides improved the range of weeds controlled, sometimes to the point that cultivation for weed control was not warranted. Many producers are so accustomed to cultivating they have forgotten why cultivation was necessary. The decision to cultivate should largely be based on the presence …

The Effects That Liquid And Solid Cattle Manure Have On The Water Quality Of Drainage Ditches In Putnam County, Ohio, Janelle Horstman

Honors Projects

Lake Erie has experienced harmful algal blooms with increased frequency since the mid-1990s due to excess nutrients from Rivers, such as the Maumee River, and largely agricultural watersheds. Nonpoint source pollution from agriculture contributes to eutrophication, algal blooms, and the degradation of water quality. This creates stress on aquatic fauna, reduced aesthetic quality, odor, and limits of the water for usage of drinking, recreation, and industry. This research paper asks what the contributions of having access to manure application records, soil records, and information about antibiotics have on what is known about manure management and antibiotic resistance, which has been …

Comparison Of Herbicide Systems For Dark Fire-Cured Tobacco, William A. Bailey, Tim Lax, Bobby Hill

Plant and Soil Sciences Research Report

Field experiments were conducted at Murray, KY in 2005, 2006, and 2007 to compare dark tobacco tolerance and weed control from various herbicide systems applied prior to transplanting. Herbicide treatments included sulfentrazone at 0.38 lb ai/A (12 oz/A Spartan 4F) applied pretransplant (PT), clomazone at 1 lb ai/A PT (2.67 pt/A Command 3ME), sulfentrazone at 0.38 lb ai/A plus clomazone at 1 lb ai/A PT, pendimethalin at 1.48 lb ai/A (3.6 pt/A Prowl 3.3EC) applied pretransplant incorporated (PTI), pendimethalin at 1.48 lb ai/A PTI followed by sulfentrazone at 0.38 lb ai/A PT, pebulate at 4 lb ai/A PTI (2.67 qt/A …

Boron Nutrition Of Burley And Dark Tobacco, Laura Ann Frakes Mitchell

Theses and Dissertations--Plant and Soil Sciences

The incidences of suspected Boron (B) deficiency have increased recently in Kentucky tobacco fields, potentially due to recent changes in management practices. The symptoms observed in the field include; hollow stalk, stunted growth, deformed or no bud formation, small slits on the lower leaf midrib and uncontrollable breaking of the midrib approximately two inches from the stalk. B is a micronutrient tobacco needs in minute amounts, however excessive additions of B could cause toxicity. The objectives of this work were to 1) establish critical points for B sufficiency, 2) describe and define B deficiency and toxicity symptoms and 3) develop …

Analysis Of Vesicular Porosity In Soils Using High-Resolution X-Ray Computed Tomograpy, Judith K. Turk, Robert C. Graham

Conservation and Survey Division: Faculty and Staff Publications

Vesicular horizons are common at the surface of arid and semiarid soils and play a critical role in regulating infiltration. Most methods for examining pore morphology in the vesicular horizon involve physical sectioning of the sample and individual measurement of pores, which is time-consuming and provides an incomplete view of the pores. The objectives of this study were to (i) develop methods for the classification and characterization of pores in the vesicular horizon using high resolution X-ray computed tomography (HRXCT) and (ii) use these methods to examine the distribution of pores within vesic-ular peds. Three intact peds were scanned by …
