PR-761: 2019 Kentucky Hybrid Corn Performance Test

Cam Kenimer, Chad Lee, Matthew Piersawl, Phillip Shine | Oct. 15, 2019 (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-52: Selecting the Right Grass for Your Kentucky Lawn

Gregg Munshaw, Travis Shaddox | Aug. 29, 2019 (Major Revision)

The best grass for your lawn is not necessarily the one you like the best, but the one that is best adapted to where you live and will take less work and fewer inputs (water, fertilizer, pesticides). Many people think that since Kentucky is the "Bluegrass State," it's best to grow Kentucky bluegrass across our state. Actually, Kentucky bluegrass is only marginally adapted to our climate and can require more inputs to keep an appealing lawn than some other choices. In general, Kentucky bluegrass can be an option for parts of central and eastern Kentucky, while zoysiagrass may be a better option in western Kentucky. Tall fescue is adapted to the entire state so is a good choice for most locations. Perennial ryegrasses and fine fescues are occasionally useful in different areas of the state, depending on specific conditions.

AGR-241: Improved Turfgrass Varieties Can Reduce Your Environmental Impact

Gregg Munshaw, Travis Shaddox | Aug. 29, 2019 (New)

Turfgrasses have many benefits, but oftentimes people question if pesticides, fertilizers, and water are justified to sustain a quality turfed area. Although these inputs have long been required to produce thick and dark green turfgrass, some turfgrass breeders have focused on improving the genetics of turfgrasses to produce high quality turf with fewer inputs. Improved turfgrass varieties with increased density, better color, deeper rooting, and improved disease resistance through improved breeding can reduce the overall environmental footprint. Many people select a turfgrass species and variety based on cost, but choosing an improved variety can reduce environment risk and overall maintenance costs in the long-run.

AGR-240: Cover Crop Benefits and Challenges in Kentucky

Chad Lee, Hanna Poffenbarger, Dan Quinn | Aug. 7, 2019 (New)

A cover crop is a plant species that is grown between cash crops primarily to provide cropping system services rather than to produce a harvestable product. Services provided by cover crops include soil health improvement, soil conservation, nutrient release and capture, and weed suppression. However, like any management practice, cover crops also have challenges and limitations. This publication is intended to provide an overview of cover crop use in Kentucky and the challenges and benefits of this practice.

PR-760: 2019 Kentucky Small Grains Variety Performance Test

Bill Bruening, John Connelly, Gene Olson, Matthew Piersawl, Sandy Swanson, Dave Sanford | Jul. 12, 2019 (New)

The 2019 soft red winter wheat growing season ended with Kentucky farmers harvesting approximately 340,000 acres of the 450,000 acres planted, for a total production of 26.2 million bushels of grain. An average yield of 77 bushels per acre was estimated by NASS. The acreage not harvested for grain was primarily used for forage production and cover cropping.

HENV-402: Water Quality and Nutrient Management at Home

Rick Durham, Brad Lee, Gregg Munshaw, Suzette Walling | Jul. 2, 2019 (New)

Fertilizers and other lawn amendments benefit the residential landscape by providing or supplementing the essential nutrients for plant growth and maintenance. Commercial fertilizers are commonly formulated based on three major nutrients, nitrogen (N), phosphorus (P), and potassium (K) and each plays an important role in plant development. However, improper application of fertilizers and amendments may increase the risk of non-point source pollution of surface and ground waters.

PPFS-AG-T-5: Maintaining the Efficacy of Foliar Fungicides for Tobacco Disease Management

Bob Pearce, Emily Pfeufer | Jul. 1, 2019 (Minor Revision)

Management of resistance to fungicides is based on alternating the use of particular modes of action, or FRAC groups, which essentially presents multiple different challenges to the fungal population. Overall, fungi that are naturally resistant to a mode of action are very rare in the environment. Challenging a population with multiple different modes of action will reduce the chance of developing widespread resistance, which will prolong the efficacy of these chemicals.

AGR-239: Calibrating Boom Sprayers for Turf Applications

Gregg Munshaw, Travis Shaddox | Mar. 12, 2019 (New)

Calibrating application equipment is something many people avoid because they believe it is too time consuming or that the math involved is too confusing. Calibration, however, is critical. Applying too little can result in poor pest control and can lead to pesticide resistance. Whereas, over applying can be bad for the environment, damage the grass, and wastes money. There are several methods for calibrating sprayers. Choose the one that makes the most sense to you. Three different methods are described below. All these methods are reliable and will provide very similar application accuracy.

PR-758: 2018 Kentucky Soybean Performance Tests

Claire Venard | Dec. 11, 2018 (New)

The Kentucky Soybean Variety Performance Tests are conducted to provide an unbiased and objective estimate of the relative performance of soybean varieties commercially available 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 in the 2018 tests were entered by soybean growers, commercial companies, state and federal institutions. Forty soybean tests were planted in 2018 in Kentucky, at the eight test locations shown below. However, due to weed pressure, one location was discontinued.
