PR-661: 2013 Red and White Clover Report
Garry Lacefield, Gene Olson, Ray Smith | Nov. 18, 2013 (New)
This report provides current yield data on red and white clover varieties included in yield trials in Kentucky as well as guidelines for selecting clover varieties.
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-660: 2013 Alfalfa Report
Garry Lacefield, Gene Olson, Ray Smith | Nov. 15, 2013 (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.
PR-659: 2013 Kentucky Hybrid Corn Performance Test
Ron Curd, Cam Kenimer, Chad Lee | Nov. 11, 2013 (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.
SR-107: Sensor Technology for Variable Rate Nitrogen Applications on Wheat in Kentucky: Recommendations and Verification
Dottie Call, John James, Lloyd Murdock, Ole Wendroth | Oct. 28, 2013 (New)
Nitrogen (N) applications on wheat using sensor-based technology can improve both N use efficiency and yields.
ID-84: Iron Deficiency of Landscape Plants
Cheryl Kaiser, Edwin Ritchey, Nicole Gauthier | Oct. 16, 2013 (Major Revision)
Iron deficiency is a nutritional deficit that can occur in woody and herbaceous plants in landscapes, nurseries, greenhouses, and production fields. It is most often associated with soils that have neutral or alkaline pH (pH 7.0 or above). Plants that grow best in acidic soils are particularly vulnerable to this condition. In Kentucky, iron deficiency is most commonly observed on pin oak, willow oak, azalea, rhododendron, and blueberry, but other woody plants are also susceptible.
HENV-509: How Water Use Impacts Septic System Performance
Brad Lee | Jul. 25, 2013 (New)
The purpose of this publication is to discuss home water use patterns and suggest water conservation measures that could improve septic system performance and reduce the risks of hydraulic overload or other kinds of system failure.
PR-658: 2013 Kentucky Small Grains Variety Performance Test
Bill Bruening, Anthony Clark, John Connelly, Ron Curd, Gene Olson, Sandy Swanson, Dave Sanford | Jul. 12, 2013 (New)
The objective of the Kentucky small-grain variety performance test is to evaluate varieties of wheat, oat, and barley that are commercially available or may soon be available to Kentucky farmers. New varieties are continually 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.
PPFS-AG-F-7: Rating Scale for Brown Stripe of Orchardgrass
Leah Saylor, Ray Smith, Paul Vincelli | Jul. 1, 2013 (New)
As of right now, there is little published on how to assess foliar disease severity in forage grasses in order to determine the percentage which may be diseased. This publication provides a tool for visually determining the percentage of diseased foliar tissue in orchardgrass. It is based on the observation of individual leaves; however, it is hoped that eventually a rating system will be devised that provides disease percentages for entire plots.
ID-215: Stormwater Wetlands
Carmen Agouridis, Kristi Meier | Jul. 1, 2013 (New)
As our population has grown, so have our towns and cities, and this growth has led to an increase in stormwater runoff. Stormwater best management practices help mitigate the impact of stormwater runoff on water quality by reducing pollutant loads through physical, chemical and/or biological processes. One of the most effective BMPs at improving stormwater quality is the stormwater wetland.
