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.
PR-669: 2013 Cool-Season Grass Horse Grazing Tolerance Report
Garry Lacefield, Laurie Lawrence, Gene Olson, Tim Phillips, Ray Smith | Dec. 4, 2013 (New)
Cool-season grasses such as bluegrass, tall fescue, and orchardgrass are dominant pasture grasses for horses in Kentucky. Variety evaluations for yield have been carried out for many years, but little work has been done to establish the effect of variety on persistence when subjected to close, continuous grazing by horses. The purpose of this report is to summarize current research on the grazing tolerance of varieties of tall fescue, orchardgrass, and other species when subjected to continuous heavy grazing pressure by horses within the grazing season. The main focus will be on stand survival.
PR-672: 2013 Kentucky Soybean Performance Tests
Joshua Duckworth, Laura Jane Phelps, Claire Venard | Dec. 2, 2013 (New)
The Kentucky Soybean Variety Performance Tests are conducted to provide an unbiased and 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-670: 2013 Summer Annual Grass Report
Garry Lacefield, Gene Olson, Ray Smith | Nov. 25, 2013 (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 2009-2013 forage yield trials with sudangrass, sorghum/sudangrass, millets, and teff.
PR-667: 2013 Red and White Clover Grazing Tolerance Report
Joey Clark, Garry Lacefield, Gene Olson, Ray Smith | Nov. 25, 2013 (New)
This report summarizes research on the grazing tolerance of red and white clover varieties when subjected to continuous grazing pressure.
PR-666: 2013 Alfalfa Grazing Tolerance Report
Joey Clark, Garry Lacefield, Gene Olson, Ray Smith | Nov. 22, 2013 (New)
This report summarizes research on the grazing tolerance of alfalfa varieties when subjected to continuous heavy grazing pressure during the grazing season.
PR-665: 2013 Annual and Perennial Ryegrass and Festulolium Report
Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Nov. 19, 2013 (New)
This report provides current yield data on annual and perennial ryegrass varieties in trials in Kentucky as well as guidelines for selecting varieties.
PR-664: 2013 Timothy and Kentucky Bluegrass Report
Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Nov. 19, 2013 (New)
This report provides maturity and yield data on timothy and Kentucky bluegrass varieties included in yield trials in Kentucky.
PR-662: 2013 Orchardgrass Report
David Ditsch, Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Nov. 18, 2013 (New)
This report provides current yield data on orchardgrass varieties included in yield trials in Kentucky as well as guidelines for selecting orchardgrass varieties.
PR-663: 2013 Tall Fescue and Bromegrass Report
David Ditsch, Garry Lacefield, Gene Olson, Tim Phillips, Ray Smith | Nov. 18, 2013 (New)
This report provides current yield data on tall fescue varieties and similar grass species in trials in Kentucky as well as guidelines for selecting tall fescue varieties.
