Non Technical Summary
The primary objective of the proposed research is to support the existing barley (Hordeum vulgare L.) livestock feed industry and the developing barley-to-ethanol industry on the East Coast. There is high potential to provide multiple benefits including: more income for local farmers resulting in preservation and enhancement of the rural economy and environment, lower cost fuel ethanol in the region, co-production of barley distiller's dried grains with solubles (DDGS), a protein rich product with potential uses in food and feed industries, and increased production of high-valued biomass. Growing need for domestic energy independence, banning of methyl tert-butyl ether (MTBE), and policy in the Renewable Fuels Standard has led to a major expansion of domestic fuel ethanol production. Barley is a $6 million industry in Virginia and ranks 11th among agricultural crops (VASS, 2008). Value of the barley industry stands to grow tremendously as a viable barley-to-ethanol industry develops that will purchase over $70 million of barley in the region. Wheat and barley are also valuable to Virginia farmers because of their ability to grow on soils with less water holding capacity than that needed for corn; and they are winter annuals that grow during the fall, winter, and spring months, when evaporation is lowest. Research that will enable farmers to produce these grains more economically and to garner more value for grain is, therefore, important to Virginia.

Goals / Objectives
Overall, there is a need to re-evaluate barley cultivar and management practices and decision support programs. As the demand for barley ethanol drives more barley grain production in the region, there will be a greater emphasis and need for techniques that optimize barley production. OBJECTIVES: 1. Evaluate the impact of late-season nitrogen on barley grain and DDGS protein. 2. Measure barley cultivar response to plant growth regulators and effects on grain yield and quality characteristics. 3. Evaluate intensive management practices on grain yield, yield components, and grain protein of hulled and hulless barley cultivars. OUTPUTS: Optimum management schemes for hulled and hulless barley in the Mid-Atlantic will be redefined. Sensitivity analysis examining grain yield and grain prices will be employed to determine the economic viability of intensive barley production in the Mid-Atlantic. A fact sheet based upon the production management research conducted by the participants will be prepared. Information about this project will be delivered toparticipants in regional CCA schools. Upon project completion, results will be published in a peer-reviewed journal in the agronomy discipline.
Project Methods
Objective 1: Evaluate the impact of late-season nitrogen on barley grain and DDGS protein. Field experiments will be conducted over the coming five crop seasons at three diverse locations in the Piedmont and Coastal Plain of Virginia. Treatments will consist of standard intensively managed barley with one half of the plots receiving 30 kg N ha at GS 45. The other half will not receive late-season N. Six barley cultivars, including three hulled barleys, Thoroughbred, VA06B48, and VA06B-19, three hulless barleys, Dan, Eve', and VA05H-147, and one malting type barley Charles will be planted in a randomized complete block design with four replications. Objective 2: Measure barley cultivar response to plant growth regulators and effects on grain yield and quality characteristics. Field experiments will be conducted over the coming five crop seasons at three diverse locations in the Piedmont and Coastal Plain of Virginia. All trials will be arranged in a randomized complete block design with four replications and plot size of 4.2 m2. Three hulled barley genotypes, Thoroughbred', VA06B48, and VA06B-19, selected from the Virginia Tech barley breeding program with good agronomic characteristics and diverse backgrounds will be treated with ethephon [(2-chloroethyl) phosponic acid] at the boot stage (GS 45) at rates of 0, 175, 266, and 350 g a.i. ha-1. Ethephon will be applied with a CO2 sprayer and hand boom in 23 L ha-1 water. Similarly, the product Trinexapac-ethyl [Ethyl 4-cyclopropyl(hydroxy) methylene-3,5-dioxocyclohexanecarboxylate] will be applied to the barley cultivars at GS 30 at rates of 0, 16.5, and 20 g a.i. ha-1 with a CO2 sprayer and hand boom in 23 L ha-1 water Objective 3: Evaluate intensive management practices on grain yield, yield components, and grain protein of hulled and hulless barley cultivars. Field experiments will be conducted over the coming five crop seasons at two diverse barley growing locations in Virginia. All trials will be arranged in a randomized complete block design with four replications and plot size of 4.2 m2. Yield potential of hulled and hulless barley lines derived from crosses made between superior hulled cultivars, such as Thoroughbred, will be evaluated to determine the factor(s) resulting in current yield drag in hulless barley, and also determine yield potential in advanced barley lines under intensive management. Five hulled by hulless populations in the F2 and F3 generations derived from crosses between the hulled cultivar Thoroughbred with other elite hulless lines and from crosses between the hulless cultivar Doyce with elite hulled lines will be evaluated and advanced as described above. In addition other hulled x hulless populations will be evaluated and assessed for inclusion in the proposed study in succeeding years.

Target Audience:Farmers Agribusiness Agricultural policy-makers Agricultural agencies Environmental agencies Changes/Problems:Sale of the grain-based ethanol facility in eastern Virginia resulted in a delay in the use of barley as an ethanol feedstock. We intended to study barley dried distillers grains with solubles (DDGS) in one portion of this study, but were unable to do so. What opportunities for training and professional development has the project provided?This work was a featured stop at the annual small grain field day held in Charles City County in May, 2015. More than 120 attendees visited the field plots for a discussion on barley management, improvement, and end-use quality parameters. In addition, the preliminary results from these studies were presented to more than 800 attendees at winter production meetings held throughout the Commonwealth of Virginia. How have the results been disseminated to communities of interest?Results were included in the Virginia Cooperative Extension publication 'Small Grain in 2015', posted on the VCE website in July 2015. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Field and laboratory studies were conducted and are underway in order to improve knowledge and management of barley in the region. In 2014 and 2015, a total of 11 field experiments were conducted. Results were disseminated at multiple field days and producer meetings. Virginia Cooperative Extension recommendations for most effecive use of plant growth regulators to manage barley lodging, have been updated and shared with stakeholders. Yields of hulless barley continue to improve compared to hulled barley based on breeding and management efforts, however a price premium for hulless will still be required for the crop to be economically competitive. Thoroughbred barley, derived from a cross including a malt barley parent, is currently being grown and used as the base commodity in a new commercial market to produce malt-derived beverages. Thishas led to increased interest in local production of winter malting barley for the rapidly growing craft brewing industry. Hulless barley lines and cultivars, such as Eve, Dan, and Amaze 10, having lower fiber and higher starch, protein, and metabolizable energy, are being evaluated in DE, KY, MD, NC, NE, PA, NC, and OK as feed stocks for diverse uses. Hulless barley is being produced in PA as a feed for laying hens and in OK as a finishing feed for beef cattle.

    Target Audience: Grain Producers Agribusiness persons Technical agriculture professionals (NRCS, etc) Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided? Results from these studies were presented at 11 grower meetings with various stakeholders present. In addition several small group meetings of stakeholders in the local barley production effort were conducted with the overall effect of providing the best management advice. How have the results been disseminated to communities of interest? In the publication 'Small Grains in 2013'. http://www.pubs.ext.vt.edu/CSES/CSES-62/CSES-62_pdf.pdf What do you plan to do during the next reporting period to accomplish the goals? We will continue field and laboratory evaluations on barley agronomic and end-use quality, andcontinue research on how management and the interaction of management and genetics will influence these characters.

    Impacts
    What was accomplished under these goals? Activities associated with this program support increased barley production with accurate and modern production recommendations. Each year, we evaluate more than 50 barley lines in multiple environments in Virginia and report these findings to the grains industry via extension publications. These reports on barley variety performance annually affect almost 50,000 acres in Virginia. Given the diversity in climate and the economic importance of variety selection on overall farm profitability, there is an ongoing need for current information on variety performance in our environment. Utilizing the best cultivar can result in yield increases that annually generate over $3 million for Virginia barley producers. In 2012-13 we also evaluated disease by cultivar interactions in malt-type barley lines to provide more realistic estimates of yield potential and end use quality.

    Progress 10/01/10 to 09/30/11

    Outputs
    OUTPUTS: Field studies were conducted at five locations throughout the Piedmont and Coastal Plain regions of Virginia in 2010-11. Data from these studies will be used in grower educational meetings conducted in winter of 2011-12 and over the next few years. Approximately 235 growers and agribusiness persons were trained at multiple field demonstration events in 2011. Results to-date along with context and previous research results were presented at the 2011 Virginia Grain Producers Association annual field day in Prince George County in May, and at annual regional small grain field days in Dinwiddie and Essex counties. PARTICIPANTS: Partners on this project include the Virginia Small Grains Board and the Virginia Grain Producers Association. The Association is a volunteer group of growers and industry that work to promote the grain, including barley, industry in the state. The Small Grains board is charged with administering grain checkoff funds in Virginia. Board representative are appointed by the governor's office and represent the breadth of the grains industry in Virginia. They have helped craft research with their comments and have attended trainings and field events. TARGET AUDIENCES: Target audiences include growers throughout Virginia as well as crop advisers, industry personnel, regulatory agency personnel, and state agencies. These groups will learn the impact of intensive barley management on grain yield and profitability. PROJECT MODIFICATIONS: With the closing of the Appomattox Bioenergy facility in Hopewell, VA, it is unlikely that the project components that include evaluation of DDGS will occur.

    Impacts
    Our goal is that optimum management schemes for hulled and hulless barley in the Mid-Atlantic will be redefined and that sensitivity analysis examining grain yield and grain prices will be employed to determine the economic viability of intensive barley production in the Mid-Atlantic. However more data are needed before firm conclusions can be drawn. In 2011, over 200 producers and their advisors were exposed to the current season results of intensive and reduced levels of barley management on grain yield and quality.
