AGR-222: Estimating Carrying Capacity of Cool Season Pastures in Kentucky Using Web Soil Survey
Krista Lea, Ray Smith | August 10, 2016 (New)
While many factors influence how many animals a farm can carry, soil type has a major influence and should be considered when purchasing, leasing, planning, or managing livestock on pastures.
AGR-221: Wildlife Benefits of Switchgrass Production in Kentucky
Tom Keene, Krista Lea, Laura Schwer, Ray Smith | July 26, 2016 (New)
Switchgrass is a versatile grass that can be utilized for forage or biomass production. Establishing and maintaining switchgrass is also beneficial to many types of wildlife by providing suitable habitat and cover.
AGR-55: Turf Care Calendar for Cool-Season Lawns in Kentucky
Gregg Munshaw | July 22, 2016 (Major Revision)
Cool-season lawns include Kentucky bluegrass, tall fescue, fine fescues, and perennial ryegrass. This calendar identifies lawn management practices and the best times of the year to perform them.
PR-707: 2016 Kentucky Small Grains Variety Performance Test
Bill Bruening, Anthony Clark, John Connelly, Blazan Mijatovic, Gene Olson, Sandy Swanson, Dave Sanford | July 1, 2016 (New)
The objective of the Kentucky small grain variety performance test is to evaluate varieties of wheat, oat, barley, triticale and cereal rye that are commercially available or may soon be available to Kentucky farmers. 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.
AGR-220: A No-math Method of Calibrating Backpack Sprayers and Lawn Care Spray Guns
Gregg Munshaw | April 7, 2016 (New)
Calibrating application equipment is something many people avoid because they believe it is too time consuming or that the math involved in the process is confusing. Calibration, however, is critical. Applying too much can be bad for the environment, injure the grass, and also wastes money. Applying too little can result in poor pest control and can lead to pesticide resistance. There are several methods that will calibrate sprayers but the no-math method is likely the most simple and reduces the chance of errors.
ID-234: Grain Sorghum (Milo) Production in Kentucky
Carl Bradley, Doug Johnson, Carrie Knott, Chad Lee, Jim Martin, Sam McNeill, Edwin Ritchey | February 8, 2016 (New)
Grain sorghum can be used for a variety of purposes including animal feed, unleavened breads, cakes, wallboard, starch, dextrose, brooms, ethanol, high quality wax, and alcoholic beverages. Grain sorghum produced in Kentucky is most commonly used for animal feed and was first grown here in the 1920s. Although acreage in Kentucky has fluctuated considerably over the years, yields have generally exceeded the national average since the 1970s, indicating that grain sorghum is an option for producers interested in diversifying grain crop operations.
PR-705: 2015 Long-Term Summary of Kentucky Forage Variety Trials
Gene Olson, Ray Smith | December 15, 2015 (New)
Forage crops occupy approximately 7 million acres in Kentucky. Forages provide a majority of the nutrition for beef, dairy, horse, goat, sheep, and wildlife in the state. In addition, forage crops play an environmentally friendly role in soil conservation, water quality, and air quality. There are over 60 forage species adapted to the climate and soil conditions of Kentucky. Only 10 to 12 of these species occupy the majority of the acreage, but within these species there is a tremendous variation in varieties. This publication was developed to provide a user-friendly guide to choosing the best variety for producers based on a summary of forage yield and grazing tolerance trials conducted in Kentucky over the past 12 to 15 years.
PR-704: 2015 Annual Grass Report: Warm Season and Cool Season (Cereals)
Bill Bruening, Gene Olson, Ray Smith | December 15, 2015 (New)
The major factor in selecting a variety of summer annual grass is yield, both total and seasonal. Growth after first cutting is strongly dependent on available moisture and nitrogen fertilization. Summer annual grasses generally have different characteristics and uses. The major factors in selecting cool season cereal grass varieties are yield, winter survival and regrowth.
PR-702: 2015 Cool-Season Grass Grazing Tolerance Report
Joey Clark, Gene Olson, Tim Phillips, Ray Smith | December 14, 2015 (New)
Cool-season grasses such as tall fescue, orchardgrass, and Kentucky bluegrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass, festulolium, and the brome grasses can be used in pasture systems. Little is known about the effect of variety on the grazing tolerance of these cool-season grass species. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, perennial ryegrass, and other species when they are subjected to continuous, heavy grazing pressure by cattle within the grazing season. The main focus will be on plant stand survival.
PR-700: 2015 Alfalfa Grazing Tolerance Report
Joey Clark, Gene Olson, Ray Smith | December 14, 2015 (New)
Alfalfa (Medicago sativa) is 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. Recent emphasis on its use as a grazing crop and the release of grazing-tolerant varieties have raised the following question: Do varieties differ in tolerance to grazing? We have chosen to use the standard tolerance test recommended by the North American Alfalfa Improvement Conference. This test uses continuous heavy grazing to sort out differences in grazing tolerance in a relatively short period of time. This report summarizes research on the grazing tolerance of alfalfa varieties when subjected to continuous heavy grazing pressure during the grazing season.
