PR-835: 2023 Kentucky Hybrid Corn Performance Test

Cam Kenimer, Chad Lee, Dalton Mertz, Phillip Shine | Nov. 15, 2023 (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.

AGR-275: Tall Fescue Novel Endophyte Varieties and Establishment for Livestock and Horse Farms

Krista Lea, Stephanie Smith, Ray Smith | Nov. 2, 2023 (New)

"Endophyte" refers to a fungus that lives within the fescue plant, meaning it cannot be seen with the naked eye. The endophyte found in tall fescue is beneficial to the plant: It gives tall fescue insect resistance, enhanced grazing tolerance, and greater persistence in stressful environments. The major disadvantage of some of the endophytes of tall fescue is that they produce toxic alkaloids that have detrimental effects on many types of livestock.

ID-276: Proper Grounding as Part of an Electric Fencing System

Morgan Hayes, Chris Teutsch | Nov. 1, 2023 (New)

Electric fencing provides a successful boundary by shocking an animal when there is contact between the animal and the fence wire. For electric fencing to work properly, current or electricity from the fence must travel through the animal, into the ground, and back to the energizer. The grounding on the energizer works as an "antenna" to collect the current and complete the circuit, which allows the animal to feel the shock. Frustration with electric fencing occurs when animals do not receive a proper shock when they first come in contact with the fence.

PR-833: 2023 Kentucky Soybean Variety Performance Trials

Bill Bruening, Cam Kenimer, Dalton Mertz, Phillip Shine | Oct. 31, 2023 (New)

The Kentucky Soybean Variety Performance Trials are conducted to provide an unbiased and objective estimate of the relative performance of soybean varieties commercially available in Kentucky. Annual evaluation of soybean varieties 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.

HENV-713: BMP Maintenance and Operation: Retention Basin

Benjamin Currens, Andrea Drayer, Rick Durham, Brad Lee | Oct. 12, 2023 (New)

Retention basins, or wet ponds, retain a deep, permanent pool of water that can collect stormwater and release it slowly to maintain a desired water level, after which the excess stormwater is released slowly via an outlet (drawdown orifice). Retention basins should always have a baseline level of water present and may be vegetated. Retention basins provide a higher level of pollutant retention (up to 80 percent) and a lower chance of sediment resuspension than detention basins (dry ponds).

HENV-714: BMP Maintenance and Operation: Grass Swale

Benjamin Currens, Andrea Drayer, Rick Durham, Brad Lee | Oct. 12, 2023 (New)

Grass swales, or dry swales, are designed to transport stormwater, promote infiltration, and capture sediment during a storm event. Grass swales are turfgrass-planted channels constructed with wide bottoms to encourage infiltration of stormwater into the underlying soil. Vegetation in the channel functions to reduce the speed of stormwater and trap sediment as water is conveyed through the channel. When functioning properly, these swales hold water no longer than six hours after a storm and should remain dry until the next storm event.

HENV-712: BMP Maintenance and Operation: Filter Strip

Benjamin Currens, Andrea Drayer, Rick Durham, Brad Lee | Oct. 12, 2023 (New)

Filter strips are planted and maintained strips of vegetation designed to provide pretreatment of stormwater runoff before it flows into adjacent best management practices (BMPs). Gently sloped, the dense vegetation within the strip reduces the speed of stormwater. This allows for the capture of sediment as stormwater from impervious surfaces passes through the filter strip.

HENV-715: BMP Maintenance and Operation: Detention Basin

Benjamin Currens, Andrea Drayer, Rick Durham, Brad Lee | Oct. 12, 2023 (New)

Detention basins, or dry ponds, are designed to collect water during a storm event and hold it for a certain amount of time, usually 48 hours. This short impoundment of stormwater allows pollutants carried in the stormwater to settle to the bottom of the basin before collected stormwater is released through a slow-release outlet. When functioning properly, these basins should remain dry after the release of water until the next storm event.

ID-275: Practical Corn Silage Harvest and Storage Guide for Cattle Producers

Donna Amaral-Phillips, Chad Lee, Jeff Lehmkuhler, Nick Roy | Sep. 27, 2023 (New)

Corn silage is often referred to as the "king of forages" and for good reason. With adequate and timely rainfall and normal environmental temperatures during the growing season, corn silage can yield 20 to 25 (or more) tons as fed per acre. Even in years with limited soil moisture, this crop can provide needed forage when harvested and stored properly although whole plant yield and/or grain content is often reduced.
