ID-230: Blackpatch of Forage Legumes: Cause of Slaframine Toxicosis or "Slobbers" in Animals

Michelle Arnold, Shane Bogle, Bob Coleman, Ray Smith, Kiersten Wise | March 5, 2021 (Major Revision)

Blackpatch is an important fungal disease of forage legumes in Kentucky. A metabolite produced by the fungus can result in slaframine toxicosis or "slobbers" in many animals. The fungal disease was first reported in Kentucky in 1933 on red clover. Most Extension literature associates blackpatch and slaframine with red clover, which is very susceptible to the disease. However, many forage legumes including alfalfa can be infected by the causal fungus.

AGR-262: Utilizing Drought Stressed Soybeans for Forage

Jimmy Henning, Ray Smith, Chris Teutsch, Katherine VanValin | February 10, 2021 (New)

Although soybeans are commonly grown as a grain crop, they can be grazed or harvested as either a hay or silage crop. This most commonly occurs when the grain potential of the soybean crop has been reduced by drought, hail damage, or early frost. A realistic forage yield expectation for drought stressed soybeans would be 1.5 to 2.0 tons of dry matter per acre. The objective of this article is to provide practical tips for successfully, grazing, conserving and feeding drought stressed soybeans.

PR-795: 2020 Soybean Yield and Quality Contest

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. Therefore, in 1980, an annual soybean yield contest was initiated in Kentucky to document the agronomic practices utilized by producers.

AGR-173: Baling Forage Crops for Silage

Jimmy Henning, Ray Smith, Chris Teutsch | January 11, 2021 (Major Revision)

Forage may be stored for winter feeding when pasture production is limited, for use in confinement feeding systems, or for cash hay. Dry hay is the most popular storage method since it stores well for long periods and is better suited to cash sale and shipping than high moisture forages. However, silage may be more suitable in situations where hay curing is difficult. It is possible to make high quality silage or haylage using long (unchopped) forage crops baled with large round balers, although balers may need modification to handle wet material.

AGR-255: Strategies for Reclaiming Hay Feeding Areas

Kelly Mercier, Chris Teutsch | December 15, 2020 (New)

Hoof damage from livestock during the winter months can result in almost complete disturbance of desired vegetation and soil structure in and around hay feeding areas. Even well-designed hay feeding pads will have significant damage at the edges where animals enter and leave. Highly disturbed areas create perfect growing conditions for summer annual weeds like spiny pigweed and cocklebur. Weed growth is stimulated by lack of competition from a healthy and vigorous sod and the high fertility from the concentrated area of dung, urine, and rotting hay. The objective of this publication is to outline strategies for rapidly establishing stands of desirable forage species on these areas.

AGR-260: Palmer Amaranth and Waterhemp Control in Corn and Soybean

Travis Legleiter | December 14, 2020 (New)

Understanding the biology of a weed is the first step in implementing an effective weed control program. This is especially true with Palmer amaranth (<i>Amaranthus palmeri</i>) and waterhemp (<i>Amaranthus tuberculatus</i>), as understanding their emergence patterns, competitiveness, adaptability, and seed production all need to be considered when developing a control program.

PR-792: 2020 Long-Term Summary of Kentucky Forage Variety Trials

Jimmy Henning, Gene Olson, Ray Smith, Chris Teutsch | December 8, 2020 (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 twenty years.

PR-794: 2020 Kentucky Soybean Performance Tests

Dalton Mertz, Claire Venard | December 7, 2020 (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 2020 tests were entered by soybean growers, commercial companies, state and federal institutions.
