AGR-236
Managing Frost Damaged Alfalfa Stands
3/19/2018 (new)

 UK Authors: Matthew Dixon, Jimmy Henning,
 Departments: Biosystems and Agricultural Engineering, Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, legumes

Wide fluctuations in springtime temperature are common in Kentucky. Late freezing temperatures in the spring can cause damage to alfalfa depending on how far along it is in breaking dormancy. This publication provides information on the effect of low spring temperatures on both established and new alfalfa stands that have begun growth, as well as a method of predicting sensitivity to late frosts or freezes.

AGR-229
Warm Season Annual Grasses in Kentucky
3/5/2018 (new)

 UK Authors: Jimmy Henning, Tom Keene, Ray Smi
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, grasses

In Kentucky, cool-season grasses produce ample forage in the spring and fall, but high temperatures and short-term drought stress often limits growth during the summer months. Warm-season annual grasses can fill this gap with relatively high quality forage when properly managed. The purpose of this publication is to provide an overview of the various summer annuals for Kentucky.

AGR-234
Sudangrass and Sorghum-sudangrass Hybrids
2/19/2018 (new)

 UK Authors: Jimmy Henning, Tom Keene, Ray Smi
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, grasses

Sorghum-sudangrass hybrids are developed by crossing sorghum with true sudangrass. The result is an annual grass that resembles sudangrass, but has coarser stems, taller growth habit, and higher yields. Like sudangrass, hybrids will regrow after grazing if growth is not limited by environmental factors. The coarse stems are difficult to cure as dry hay, therefore these grasses are best utilized for grazing, chopped silage and baleage.

Foxtail Millet
2/19/2018 (new)

 UK Authors: Jimmy Henning, Tom Keene, Ray Smi
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, grasses

Foxtail millet (German millet) is a fine-stemmed summer annual used mainly for emergency hay or pasture for cattle. It is the lowest yielding of the summer annual grasses since it will not regrow after cutting. It can also be used as a smoother crop when transitioning to other perennial forage crops. Foxtail millet is also commonly used for wildlife plantings to produce food and cover for doves, quail, and other birds.

AGR-232
Crabgrass
2/19/2018 (new)

 UK Authors: Jimmy Henning, Tom Keene, Ray Smi
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, grasses

Crabgrass possesses significant potential for supplying high quality summer forage although it is considered a weed by many. A primary advantage of crabgrass is that it is well adapted to Kentucky and occurs naturally in most summer pastures, especially those that have been overgrazed. It is also highly palatable and a prolific re-seeder. Planting an improved variety of crabgrass is recommended because the production of naturally-occurring ecotypes varies greatly. Crabgrass is best utilized by grazing.

Pearl Millet
2/19/2018 (new)

 UK Authors: Jimmy Henning, Tom Keene, Ray Smi
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, grasses

The primary benefits of pearl millet are that it does not contain prussic acid and is not susceptible to the sugarcane aphid. Dwarf varieties are available, which are leafier and better suited for grazing.

AGR-230
Forage Sorghum
2/19/2018 (new)

 UK Authors: Jimmy Henning, Tom Keene, Ray Smi
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, grasses

Forage sorghum is the tallest of the summer annuals, reaching 6 to 15 feet in height and is best harvested as silage. Taller varieties produce high forage yield but can lodge, making them difficult to harvest mechanically. Some varieties have been developed that are shorter with increased resistance to lodging. Forage sorghums, like corn, are harvested once per season by direct chopping. While forage sorghum yields are similar to corn, they are lower in energy. The primary advantage of utilizing sorghum for silage production is its greater drought tolerance.

Wildlife Benefits of Switchgrass Production in Kentucky
7/26/2016 (new)

 UK Authors: Tom Keene, Krista Lea, Laura Schw
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags:

Switchgrass is a versatile grass that can be utilized for forage or biomass production. Establishing and maintaining switchgrass is also beneficial to many types of wildlife by providing suitable habitat and cover.

ID-199
Prechilling Switchgrass Seed on Farm to Break Dormancy
4/23/2012 (new)

 UK Authors: Holly Boyd, Cindy Finneseth, T
 Departments: Plant and Soil Sciences, Regulatory Services
 Series: Interdepartmental (ID series)
 Tags: cover and forage crops, farm crops, grasses

Switchgrass (Panicum virgatum L.) is a warm-season, perennial bunch-type grass native to the North American Tallgrass Prairie. It has been investigated as a renewable energy crop due to its high productivity across a wide geographic range including various environmental conditions and soil types. Switchgrass has also been used for erosion control, summer grazing in pasture and hay systems for cattle, native prairie restoration, wildlife habitat, fiber production, and as an ornamental grass.

 UK Authors: Tom Keene, Garry Lacefield, Ray
 Departments: Plant and Soil Sciences
 Series: Agronomy (AGR series)
 Tags: cover and forage crops, farm crops, grasses

Native warm-season perennial grasses are well adapted for production in Kentucky's climate and soils. In this publication, native warm-season perennial grasses that have the greatest forage potential for Kentucky are described. Management techniques necessary to establish stands and keep them productive are also discussed.
