PR-817: 2022 Alfalfa Report

Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | Dec. 5, 2022 (New)

Alfalfa (Medicago sativa) has historically been the highest-yielding, highest-quality forage legume grown in Kentucky. It is an important part 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.
This report provides yield data on alfalfa varieties included in current yield trials in Kentucky as well as guidelines for selecting alfalfa varieties. Tables 13 and 14 (Roundup Ready varieties) show a summary of all alfalfa varieties tested in Kentucky during the past 18 years. The UK Forage Extension website (https://forages.ca.uky.edu) contains electronic versions of all forage variety testing reports from Kentucky and surrounding states as well as a large number of other forage publications.

ID-217: Forage-Related Disorders in Cattle: Nitrate Poisoning

Michelle Arnold, Jeff Lehmkuhler, Megan Romano, Ray Smith | Oct. 24, 2022 (Minor Revision)

Nitrates are natural constituents of all plants. Under normal conditions, plants take up nitrate through their roots and transport it to the leaves for use in photosynthesis. However, photosynthesis decreases under adverse environmental conditions (e.g., drought; leaf damage due to disease, hail, frost, insects, or herbicides; cool and cloudy weather; and other plant stressors). When photosynthesis is reduced, nitrate transportation to the leaves slows also. Potentially toxic nitrate concentrations can remain in the lower stalks and stems.

AGR-267: Ordering/Casing Burley and Dark Tobacco - Post-Curing Management Practices

Andy Bailey, Bob Pearce | Sep. 8, 2022 (New)

Market preparation of burley and dark tobacco involves removing cured tobacco from the curing facilities (takedown), removing the stalks from the stick (bulking), removing cured leaves from tobacco stalks (stripping) and packaging for the market (baling). These processes can only be performed when cured leaves are sufficiently pliable to avoid breakage.

AGR-50: Lawn Establishment in Kentucky

Gregg Munshaw | Jul. 29, 2022 (Minor Revision)

The methods you use, the grass you select and the time of year that you plant your lawn will often determine the quality and ease of maintenance. When it comes to establishing a new lawn, the key is to do everything properly from the start so you will not have to try to fix the lawn once it is established.

PR-813: 2022 Kentucky Small Grain Variety Performance Trial

Bill Bruening, John Connelly, Gene Olson, Phillip Shine, Sandy Swanson, Dave Van Sanford | Jul. 12, 2022 (New)

The objective of the Kentucky small grain variety performance trial is to evaluate varieties of wheat, oat, barley, triticale, 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 localities and individual requirements.

AGR-266: Chemical Topping of Burley Tobacco

Andy Bailey, Bob Pearce | Jun. 17, 2022 (New)

Pastures for sheep and goats are fertilized to ensure a reliable supply of energy, protein, and other nutrients for a long season of grazing. Management of plant nutrients maintains a balance of improved grasses and legumes and improves forage species competitiveness with many pasture weeds. The most important part of obtaining fertilizer recommendations is collecting a representative soil sample to send to the lab.

ID-2: Guide to Plants of Kentucky Potentially Poisonous to Livestock

Michelle Arnold, J.D. Green, Megan Romano | Apr. 22, 2022 (Minor Revision)

Poisonous plants are responsible for considerable losses to farmers and stockmen in Kentucky. Many cases of plant poisoning are never diagnosed or even suspected. There are nearly 100 different species of plants growing in Kentucky that under certain conditions may be poisonous to livestock, although only one third of these are likely to cause serious trouble. The primary purpose of this publication is to enable individuals to recognize, at sight, some plants which are known to be dangerously poisonous, and to have knowledge of those additional plants, which, under certain conditions, may cause trouble.
