PR-676: 2014 Alfalfa Report

Garry Lacefield, Gene Olson, Ray Smith | Nov. 25, 2014 (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.

AGR-215: Evaluating Land Resource Potentials in Kentucky

Edwin Ritchey, Ray Smith | Aug. 15, 2014 (New)

The most successful land use decisions are those where the intended use matches the capabilities of the land. Determining the capability of the land begins with a visual assessment of the landscape such as topography (percent slope) and surface drainage patterns followed by a closer examination of the soil physical and chemical characteristics. The purpose of this publication is to provide a basic understanding of the relationship between these landscape and soil properties to facilitate wise land use decisions.

ID-220: Cyanide Poisoning in Ruminants

Michelle Arnold, Cynthia Gaskill, Garry Lacefield, Ray Smith | Apr. 21, 2014 (New)

Cyanide poisoning of livestock is commonly associated with johnsongrass, sorghum-sudangrass, and other forage sorghums. Choke-cherry or wild cherry, elderberry, and arrow grass are less frequent causes. Young plants, new shoots, and regrowth of plants after cutting often contain the highest levels of cyanogenic glycosides. The risk from potentially dangerous forages may be reduced by following the management practices in this publication.

PR-668: 2013 Cool-Season Grass Grazing Tolerance Report

Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Dec. 4, 2013 (New)

Cool-season grasses such as tall fescue and orchardgrass are the primary pasture grasses in Kentucky. Other species such as perennial ryegrass, festulolium, and prairie brome 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-671: 2013 Long-Term Summary of Kentucky Forage Variety Trials

Garry Lacefield, Gene Olson, Ray Smith | Dec. 4, 2013 (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 10 to 12 years.
