PR-778: 2020 Kentucky Small Grains Variety Performance Test

Bill Bruening, John Connelly, Gene Olson, Phillip Shine, Sandy Swanson, Dave Van Sanford | Jul. 2, 2020 (New)

The objective of the Kentucky small grain variety performance trials is to evaluate varieties of wheat, oat, barley, triticale, spelt, and cereal rye that are commercially available or may soon be available to Kentucky farmers. New varieties continually are 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.

AGR-251: Quick Identification Tips for Turfgrasses Commonly Grown in Kentucky

Gregg Munshaw, Travis Shaddox | Jun. 19, 2020 (New)

Species of both warm- and cool-season turfgrasses are grown in Kentucky. Identification of these grasses is critical for implementation of proper management practices. Grass identification is commonly performed by observing specific parts of the plant. For a review of the parts of the grass plant, see AGR-216: 'Turfgrasses of Kentucky'. The objective of this extension publication is to provide concise identification tips to properly identify Kentucky turfgrasses.

PR-777: 2019 Soybean Yield and Quality Contest

Matt Adams, Danny Adams, Matt Futrell, Clint Hardy, Curt Judy, Carrie Knott, Leann Martin, Tyler Miller, Michelle Simon, Darrell Simpson, Mike Smith | Jun. 2, 2020 (New)

In Kentucky, farmers grow soybeans in two common soybean production systems: full season and double crop. Farmers plant full season soybeans in the spring and harvest them that fall, so they have harvested one crop in one calendar year. Farmers plant double crop soybeans after wheat harvest in June. These soybeans are harvested later that fall, making them the second crop harvested in the same calendar year. Both systems are important to the overall production of soybean in Kentucky. Identifying management practices that maximize yield of each system is a vital step in identifying the most profitable management systems for Kentucky. Therefore, in 1980, an annual soybean yield contest was initiated in Kentucky to document the agronomic practices utilized by producers.

SR-112: Science of Hemp: Production and Pest Management, 2020

Bernadette Amsden, Samantha Anderson, Ric Bessin, Susan Fox, Nicole Ward Gauthier, Ross Guffey, Tom Keene, Tyler Mark, Bob Pearce, Christopher Schardl, Jonathan Shepherd, Frank Sikora, Desiree Szarka, Raul Villanueva | Mar. 13, 2020 (New)

Hemp is grown for fiber, grain, and cannabinoid extraction in Asia, Europe, and the Americas. Until recently, Cannabis sativa has been classified as a Schedule 1 controlled substance in the US. The Agricultural Act of 2014 (Farm Bill) allowed for reintroduction of industrial hemp under a pilot research program. Acreage increases and addition of state legislation resulted in over 78,000 acres of hemp grown in 23 states by the end of 2018. Hemp became a legal commodity under the 2018 Farm Bill, and by the end of 2019, over 500,000 licensed acres were documented across 45 states. Canada re-introduced the crop in 1998, and in 2018, almost 78,000 acres of hemp were licensed and planted.

PR-767: 2019 Timothy and Kentucky Bluegrass Report

Jimmy Henning, Gene Olson, Tim Phillips, Ray Smith, Chris Teutsch | Mar. 2, 2020 (New)

Timothy (Phleum pratense) is the fourth most widely sown cool-season perennial grass used in Kentucky for forage--after tall fescue, orchardgrass, and Kentucky bluegrass. It is a late-maturing bunchgrass that is primarily harvested as hay, particularly for horses. It also can be used for grazing or wildlife habitat. Kentucky bluegrass (Poa pratensis) is a high-quality, highly palatable, long-lived pasture plant with limited use for hay. It tolerates close, frequent grazing better than most grasses. It has low yields and low summer production and becomes dormant and brown during hot, dry summers. Kentucky bluegrass is slow to establish.

AGR-249: Potassium for Kentucky Turfgrasses

Gregg Munshaw, Travis Shaddox | Feb. 14, 2020 (New)

Potassium (K) is an essential plant element and is the most abundant mineral, macro-nutrient in turfgrass after nitrogen (N). Sufficient concentrations of K are important to maximize turfgrass tolerance to stresses caused by temperature, drought, traffic, and salinity. Understanding the function, soil content, and fertilizer forms of K is essential to creating an efficient nutrient management program.

AGR-248: The Fate of Nitrogen Applied to Kentucky Turfgrass

Gregg Munshaw, Travis Shaddox | Feb. 14, 2020 (New)

The quality of Kentucky's surface and ground waters are of utmost importance to flora and fauna living in these waters. The growth of flora and fauna is directly related to the amount of available nutrients in these waters. In addition, we use these waters as the primary source of drinking water for ourselves and our families. A wide range of compounds may be found in these waters, the most common of which may be nitrate (NO3-). The sources of nitrogen (N) may include, but are not limited to, atmospheric deposition, septic tanks, effluent water disposal, agricultural fertilization, and landscape fertilization. The objective of this publication is to identify and describe the sources and potential fates of N applied to Kentucky turfgrass.

AGR-245: Nitrogen for Kentucky Turfgrasses

Gregg Munshaw, Travis Shaddox | Feb. 13, 2020 (New)

Nitrogen (N) fertilizer is required by turfgrass in larger quantities than any other mineral nutrient because the plant demand for N is high and the supply of N from the natural environment is normally low. In instances where N is not applied according to the University of Kentucky recommendations, applied N can increase the risk of surface and ground water contamination. The objective of this document is to describe the function of N in turfgrass, explain how soil and tissue tests can be used to manage N applications, and to describe the various N fertilizer sources available for application to turfgrass.
