PR-782: 2020 Red and White Clover Report
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Nov. 16, 2020 (New)
This report provides current yield and persistence data on red and white clover varieties included in yield trials in Kentucky as well as guidelines for selecting clover varieties. Tables 14 and 15 show a summary of all clover varieties tested in Kentucky for the past 15 years. The UK Forage Extension website at forages.ca.uky.edu contains electronic versions of all forage variety testing reports from Kentucky and surrounding states and a large number of other forage publications.
PR-780: 2020 Kentucky Hybrid Corn Performance Test
Cam Kenimer, Chad Lee, Phillip Shine | Nov. 16, 2020 (New)
The objective of the Kentucky Hybrid Corn Performance Test is to provide relative performance estimates of hybrid seed corn sold in Kentucky. The test attempts to treat every hybrid similarly in an unbiased manner. Agronomic practices that meet or exceed university guidelines are implemented at each location.
PR-778: 2020 Kentucky Small Grains Variety Performance Test
Bill Bruening, John Connelly, Gene Olson, Phillip Shine, Sandy Swanson, Dave Van Sanford | Jul. 2, 2020 (New)
The objective of the Kentucky small grain variety performance trials is to evaluate varieties of wheat, oat, barley, triticale, spelt, and cereal rye that are commercially available or may soon be available to Kentucky farmers. New varieties continually are 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.
PR-777: 2019 Soybean Yield and Quality Contest
Matt Adams, Danny Adams, Matt Futrell, Clint Hardy, Curt Judy, Carrie Knott, Leann Martin, Tyler Miller, Michelle Simon, Darrell Simpson, Mike Smith | Jun. 2, 2020 (New)
In Kentucky, farmers grow soybeans in two common soybean production systems: full season and double crop. Farmers plant full season soybeans in the spring and harvest them that fall, so they have harvested one crop in one calendar year. Farmers plant double crop soybeans after wheat harvest in June. These soybeans are harvested later that fall, making them the second crop harvested in the same calendar year. Both systems are important to the overall production of soybean in Kentucky. Identifying management practices that maximize yield of each system is a vital step in identifying the most profitable management systems for Kentucky. Therefore, in 1980, an annual soybean yield contest was initiated in Kentucky to document the agronomic practices utilized by producers.
PR-767: 2019 Timothy and Kentucky Bluegrass Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Mar. 2, 2020 (New)
Timothy (Phleum pratense) is the fourth most widely sown cool-season perennial grass used in Kentucky for forage--after tall fescue, orchardgrass, and Kentucky bluegrass. It is a late-maturing bunchgrass that is primarily harvested as hay, particularly for horses. It also can be used for grazing or wildlife habitat. Kentucky bluegrass (Poa pratensis) is a high-quality, highly palatable, long-lived pasture plant with limited use for hay. It tolerates close, frequent grazing better than most grasses. It has low yields and low summer production and becomes dormant and brown during hot, dry summers. Kentucky bluegrass is slow to establish.
PR-776: Kentucky Corn Silage Hybrid Performance Report, 2019
Ricky Arnett, Matthew Campbell, Chad Lee, Linda McClanahan, Nick Roy | Jan. 10, 2020 (New)
The objective of the Silage Corn Hybrid Performance Test is to provide unbiased forage yield and quality data for corn hybrids commonly grown for silage in Kentucky. Corn hybrids were evaluated for silage performance on cooperating farms. Representatives from seed companies submitted hybrids of their choosing. Most companies submitted only two (2) hybrids. One company supplies a third hybrid that serves as a check.
PR-774: 2019 Long-Term Summary of Kentucky Forage Variety Trials
Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 18, 2019 (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-773: 2019 Annual Grass Report: Warm Season and Cool Season (Cereals)
Bill Bruening, Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 12, 2019 (New)
Summer annual grasses provide an important forage crop option for producers in Kentucky. These grasses are mainly used as emergency or supplemental hay and pasture crops, but little information is available on their yield potential. The purpose of this publication is to summarize the University of Kentucky 2013-2019 forage yield trials with sudangrass, sorghum/sudangrass, millets, teff, and cereal crops. Cool season annual grasses (specifically cereal crops) are also used as forages crops for hay, baleage or grazing. The cereal crops used in this report are wheat (Triticum aestivum), rye (Secale cereale), oats (Avena sativa) and triticale (Triticum secale).
PR-762: 2019 Fruit and Vegetable Research Report
Doug Archbold, Daniel Becker, Win Dunwell, Rachel Rudolph, Chris Smigell, John Snyder, John Strang | Dec. 5, 2019 (New)
Fruit and vegetable production continues to show sustained growth in Kentucky. As the industry grows around a diverse collection of marketing tactics (wholesale, farmer markets, CSAs, and direct to restaurants) as well as various production systems, there continues to be a need for applied practical information to support the industry.Evaluation of varieties is a continuing necessity and allows us to provide the most up to date information in communications with vegetable growers. The vegetable variety trial results are the basis for updating the recommendations in our Vegetable Production Guide for Commercial Growers (ID-36).
PR-771: 2019 Cool-Season Grass Grazing Tolerance Report
Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Dec. 5, 2019 (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 bromegrasses 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.
