PR-629: 2011 Orchardgrass Report
Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Dec. 19, 2011 (New)
Orchardgrass (Dactylus glomerata) is a high-quality, productive, cool-season grass that is well adapted to Kentucky conditions. This grass is used for pasture, hay, green chop, and silage, but it requires better management than tall fescue for greater yields, higher quality, and longer stand life. It produces an open, bunchtype sod, making it very compatible with alfalfa or red clover as a pasture and hay crop or as habitat for wildlife.
PR-627: 2011 Alfalfa Report
Garry Lacefield, Gene Olson, Ray Smith | Dec. 19, 2011 (New)
Alfalfa (Medicago sativa) has historically been the highest yielding, highest quality forage legume grown in Kentucky. It forms the basis of Kentucky's cash hay enterprise and is an important component in dairy, horse, beef, and sheep diets. Choosing a good variety is a key step in establishing a stand of alfalfa. The choice of variety can impact yield, thickness of stand, and persistence.
PR-628: 2011 Red and White Clover Report
David Ditsch, Garry Lacefield, Gene Olson, Ray Smith | Dec. 19, 2011 (New)
Red clover (Trifolium pratense L.) is a high-quality, short-lived, perennial legume that is used in mixed or pure stands for pasture, hay, silage, green chop, soil improvement, and wildlife habitat. This species is adapted to a wide range of climatic and soil conditions. Stands of improved varieties are generally productive for two-and-a-half to three years, with the highest yields occurring in the year following establishment. Red clover is used primarily as a renovation legume for grass pastures. It is a dominant forage legume in Kentucky because it is relatively easy to establish and has high forage quality, high yield, and animal acceptance.
PR-625: 2011 Kentucky Soybean Performance Tests
Bill Bruening, Kolter Kalberg, Eugene Lacefield, Claire Venard | Nov. 7, 2011 (New)
The Kentucky Soybean Variety Performance Tests are conducted to provide an unbiased, objective estimate of the relative performance of soybean varieties in Kentucky. This information may be used by growers and seed producers to aid in selecting varieties that will give the highest total production in a specific situation. Soybean cultivars were entered by soybean growers, commercial companies, and state and federal institutions.
PR-624: 2011 Kentucky Hybrid Corn Performance Test
Ron Curd, Chad Lee, Bill Pearce | Nov. 4, 2011 (New)
The objective of the Kentucky Hybrid Corn Performance Test is to provide performance estimates of hybrid seed corn sold in Kentucky. The test has been conducted in an unbiased manner according to accepted agronomic practices.
ID-193: Profitability of Nitrogen Applications for Stockpiling Tall Fescue Pastures: 2011 Guide
Kenny Burdine, Greg Halich, John Johns, Lloyd Murdock, Ray Smith | Oct. 5, 2011 (New)
The concept of stockpiling is pretty straightforward, but the challenge each year is to determine the likelihood that this practice will be profitable given the economic and agronomic conditions present at mid-summer. This practice can yield significant benefits, but it also carries significant costs. These benefits and costs must be quantified and compared to assess the overall profitability of the practice.
ID-191: Climate Change: A Brief Summary for Kentucky Extension Agents
Tom Barnes, Ric Bessin, Jeffrey Bewley, Roy Burris, Tim Coolong, Lee Meyer, Joe Taraba, Paul Vincelli, George Wagner | Sep. 20, 2011 (New)
Nearly all climate science experts agree that global warming is occurring and that it is caused primarily by human activity. Regardless of what you may read on blogs or in the media, there is no meaningful scientific controversy on these points. The future impacts of global warming are difficult to predict, but the changes caused by greenhouse gases are expected to increasingly affect Kentucky agriculture.
AGR-202: Corn Growth Stages and Growing Degree Days: A Quick Reference Guide
Chad Lee | Sep. 13, 2011 (New)
Corn growth stages are based on the leaf collar method, where fully emerged leaves (leaf collar visible) are used to stage vegetative development. Growing degree days (GDDs) are used to relate temperature to corn growth and development.
AGR-203: Improving the Productivity of Landscapes with Little or No Topsoil
Edwin Ritchey | Aug. 16, 2011 (New)
Landscapes with little or no topsoil can make it difficult to produce a garden, lawn, or other plants. Topsoil, dark in color compared to the underlying soil, is the part of a soil that is most biologically active, nutrient rich, and easily managed. It also is usually more easily worked than underlying soil, supplies most of the plant's water and nutrients, and is generally best for plant growth.
PR-623: 2011 Kentucky Small Grains Variety Performance Test
Bill Bruening, John Connelly, Gene Olson, Sandy Swanson, Charles Tutt, Dave Sanford | Jul. 7, 2011 (New)
The objective of the Kentucky small grain variety performance test is to evaluate varieties of wheat, oat and barley that are commercially available or may soon be available to Kentucky farmers. New varieties are continually being developed by agricultural experiment stations and commercial firms. Annual evaluation of small grain varieties and selections provides farmers, seed producers, and other agricultural workers with current information to help them select the varieties best adapted to their locality and individual requirements.
