G75-246 Preventing Tail Biting In Swine (Anti-Comfort Syndrome) (Revised January 1983), Robert Fritchen, Alex Hogg

University of Nebraska-Lincoln Extension: Historical Materials

Tail biting in swine could be renamed the anti-comfort syndrome, for any feature of the pig's environment that makes it uncomfortable may be expressed as tail biting. Tail biting is the most common of the pig's antisocial vices, but not the only one. Ear chewing, navel sucking and acute cannabalism are other forms of antisocial expressions.

This NebGuide analyzes the management situation of tail biting.

Ec75-1427 Ponds For Nebraskans, Philip S. Gipson, Darrell E. Feit, Jerry W. Morris

University of Nebraska-Lincoln Extension: Historical Materials

Nebraskans construct ponds for a variety of reasons. Early ponds were usually constructed to provide water for livestock. Today they are for soil and water conservation, livestock water supply, and recreational activities such as fishing, hunting, and picnicking. The trend is to design ponds for multiple use and benefit.

This extension circular includes information on where and how to build a pond; farm pond design; wildlife planting and erosion control; control of water plants; wildlife plants for farm ponds; and managing for sport fishing.

G74-187 Care Of Cactus In The Home, Dale T. Lindgren

University of Nebraska-Lincoln Extension: Historical Materials

The care and propagation of cacti is featured in this NebGuide. A special section on Christmas cactus is included.

Cacti are among the most fascinating groups of indoor plants. Often described as arid desert plants, they also are found in forests and on prairies. In Nebraska several native species of cactus intermingle with prairie grasses.

G74-202 Wheat Soil-Borne Mosaic Disease (Revised October 2001), John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Host range, symptoms, disease cycle, and control options for wheat soil-borne mosaic disease are discussed.

Wheat soil-borne mosaic virus affects wheat (Triticum aestivum L.) growing primarily in central, eastern and west central Nebraska. This disease occurs annually; however, its effect on crop production in Nebraska varies from year to year due to variety selection, cropping practices and environmental conditions favoring disease development. In years when spring temperatures remain cool for extended periods, the virus remains active in infected plants, enhancing symptom development and increasing yield loss. The virus reduces tillering and affects kernel weights and test weights.

G74-117 Alfalfa In Swine Diets (Revised November 1988), Duane Reese, D. Murray Danielson

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska ranks first in dehydrated alfalfa meal and seventh in alfalfa hay production in the United States, with production in all counties of the state. With this availability of alfalfa, its use in swine diets should be considered.

The performance and economic considerations of alfalfa in swine diets are detailed here, and information on mixing diets is provided.

G74-157 Foot Rot, Don Hudson

University of Nebraska-Lincoln Extension: Historical Materials

Foot rot (necrotic pododermatitis, foul foot) can be a very annoying problem. Once started in a herd and "seeded" in the soil, it may persist for quite a long time. Although the incidence of foot rot may not be high at any one time, it requires constant observation to prevent serious economic loss.

The bacterium Fusobacterium necrophorum has been reported to cause foot rot. However, researchers have not been able to reproduce typical foot rot lesions with this organism.

Recent research at the University of Missouri indicates that a combination of Fusobacterium necrophorum and Bacteroides melaninogenicus are the predominant bacteria …

G74-121 Sandbur Control In Field Corn (Revised January 1999), Gail A. Wicks, Robert G. Wilson Jr.

University of Nebraska-Lincoln Extension: Historical Materials

Sandbur can be a major weed problem in cornfields if not properly controlled. This NebGuide discusses mechanical and chemical alternatives for controlling sandbur.

Sandbur is a problem weed on coarse to fine-textured soil. The North Platte Valley, southwest and west central Nebraska, and the Sandhills are areas in the state where sandbur is a major weed problem in corn. Sandbur seldom becomes a primary weed problem in eastern Nebraska. Both field (Cenchrus pauciflorus Benth.) and longspine [Cenchrus longispinus (Hack.) Fern.] sandbur grow in Nebraska.

G74-123 Weed Control In Reduced Tillage Corn (Revised May 1982), Russell Moomaw, Alex Martin, David P. Shelton

University of Nebraska-Lincoln Extension: Historical Materials

Weeds compete with corn plants for water, nutrients and light. Historically, the soil has been extensively tilled to prepare a seedbed and to lessen or remove weed competition. This tillage centered around moldboard plowing.

Results of a recent survey indicate that most Nebraska farmers now use some form of reduced tillage, with the moldboard plow being used on only 11 percent of Nebraska's corn acreage. Reduced tillage is used in many forms.

This NebGuide discusses how to control weeds using the different types of tillage systems.

G74-171 Summer Annual Forage Grasses (Revised January 1986), Bruce Anderson, Paul Guyer

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses production practices, methods of use, and precautions for using summer annual grasses.

Summer annual grasses are used for summer pasture, green chop, hay, silage, and winter pasture. They are often used as sources of emergency forage. In addition, residues of summer annuals make an excellent seedbed mulch for new stands of perennial grass, particularly on sands.

The summer annual grasses most often used for forage in Nebraska are sudangrass, hybrid sudangrass, sorghum-sudangrass hybrids, and forage sorghums. Foxtail millet and pearl millet are used occasionally. Each of these grasses has unique growth characteristics that require proper management for …

Amaryllis can be grown outdoors throughout the year in mild climates, but must be grown indoors in Nebraska except during the warm summer months. Amaryllis is prized for its huge showy flowers ranging from scarlet or crimson to white in color, and often striped or mottled. Most amaryllis are Dutch or African hybrids selected for flower size, color and ease of forcing. The usual flowering season …

G74-165 Understand Your Soil Test: Calcium, Magnesium, Boron, Copper, Chlorine, Molybdenum, Delno Knudsen, K.D. Frank

University of Nebraska-Lincoln Extension: Historical Materials

It is possible to analyze soil samples for any of the 13 essential elements which plants obtain from the soil. This does not mean that the results obtained can be used to predict adequacy or deficiency for plant growth.

The value obtained from any chemical procedure used to determine each element must be shown to be related to (1) crop response from application of that element (correlation) and (2) the soil test level at which response occurs (calibration). Crop response is usually measured as yield, but may also be a quality factor. Field plot and greenhouse research are used to …

G74-170 Nitrates In Livestock Feeding (Revised July 1996), Richard J. Rasby, Bruce Anderson, Norman Schneider

University of Nebraska-Lincoln Extension: Historical Materials

Most forages contain some nitrates. When feeds containing nitrates are consumed by ruminants, nitrates are changed in the rumen to ammonia that is then converted by bacteria in the rumen into microbial protein. Nitrates are not always toxic to animals.

This NebGuide describes signs, causes, prevention and treatment of nitrate poisoning in livestock.

African violets are low, compact plants with attractive dark green, thick, hairy leaves. This NebGuide covers various aspects of caring for them.

The African violet (Saintpaulia ionantha) is one of the most satisfactory flowering houseplants. It is a low, compact plant with attractive dark green, thick, hairy leaves. The violet-like flowers are borne in small panicles just above the foliage. Besides various shades of blue-violet, there are also pink, fuschia, and white cultivars (varieties). Newer violets include not only cultivars with single flowers, but also those with semi-double or double rows of petals. Bi-colored flowers and those with …

G74-186 Cannas, Donald E. Janssen, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Cannas are quick growing, vigorous ornamental plants with heavy foliage and large flowers.

Flower colors range from dark red to light green. Leaf colors can be reddish-purple, bronze or green. They are used most effectively for bedding plants in public parks and larger home grounds where they can be planted in front of taller shrubbery and viewed from a distance. Their vigor and size make them less desirable for planting in restricted areas.

G74-189 Growing Dahlias, Don Steinegger, John E. Watkins, Frederick P. Baxendale

University of Nebraska-Lincoln Extension: Historical Materials

Propagation, culture, diseases, and insects of dahlias are covered here.

The dahlia is a versatile flowering plant, providing a wide array of sizes, forms and colors. Flowers range from half-inch pompons to giants. Flower forms vary from daisy-shaped singles to fully double types with intermediate forms, such as anemone.

Dahlia cultivars which flower the first year from seed are referred to as annuals. Many of these annuals form tuberous roots the first year. These tuberous roots can be saved for use next year.

G74-113 A Quick Test For Atrazine Carryover (Revised March 1989), Alex Martin, R.N. Stougaard, Patrick J. Shea

University of Nebraska-Lincoln Extension: Historical Materials

How can you tell if you have atrazine carryover in your fields? Plants grown in soil samples can tell.

Residues of atrazine may remain in the soil and affect some susceptible crops the next year. Crops most often affected include soybeans, field beans, sugarbeets, alfalfa, oats, wheat and many broadleaf horticultural crops.

Attempts to predict the extent of carryover and damage to sensitive crops the year following atrazine use have been only partially successful. The rate of atrazine disappearance and, therefore, the amount remaining the next year, is affected by soil texture, pH and organic matter content, as well as …

G74-108 Wilts Of Cucurbits (Revised October 1994), James R. Steadman, David L. Keith, Laurie Hodges

University of Nebraska-Lincoln Extension: Historical Materials

G74-142 Harvesting And Preserving Hay Crop Silage, Rick Grant, Rick Stock

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes principles of successful hay crop harvest, silage preservation, management techniques to obtain high quality hay crop silage, and proper use of silage storage facilities.

Most hay (legume and grass) crops can be ensiled, or made into silage, successfully. For best feeding value and preservation, consider the special requirements for ensiling each crop.

Hays to be ensiled should be selected on the basis of economics. Which are the most profitable for supplying nutrients? For example, legumes have a relatively higher value for dairy herds than for beef finishing operations because of dairy cows' higher requirement for protein.

G74-98 Buying A Center Pivot, John W. Addink

University of Nebraska-Lincoln Extension: Historical Materials

A center-pivot sprinkler system is a medium cost, low labor irrigation method. A few of these systems have been high cost, high labor irrigation methods. Consideration of a few details in the purchase of the system can help prevent the high cost and/or high labor.

Many different types of systems are available today. Consideration must be given to soil texture and slope of the field to be irrigated with the center-pivot. This publication covers what to look for when purchasing a center-pivot sprinkler system.

The success and usefulness of the control measures mentioned in this guide will vary due to methods of application, climatic conditions, and other factors. These recommendations are presented for the benefit of Nebraska farmers. Insecticides should be used with caution and labels should be of recent date. Information in this guide is based on University of Nebraska research results, USDA recommendations and label registrations.

G74-149 Bloat Prevention And Treatment (Revised July 1996), Dale Grotelueschen, Richard J. Rasby, Don Hudson, Bruce Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Bloat is a form of indigestion marked by an excessive accumulation of gas in the rumen. Immediately after cattle consume a meal, the digestive process creates gases in the rumen. Most of the gases are eliminated by eructation (belching). Any interruption of this normal gas elimination results in gas accumulation or bloat.

This NebGuide discusses the types of bloat which may occur in cattle and methods to prevent and treat bloat.

G74-125 Oats In Swine Diets (Revised December 1981), Ernest R. Peo, Donald B. Hudman, Mike Brumm

University of Nebraska-Lincoln Extension: Historical Materials

Oats are not considered a standard feed grain in swine diets in Nebraska because of the small acreage planted. However, oats can be used by all ages of swine with some limitations. The feeding value of oats is 80 percent that of corn. With proper formulation, limiting the amount of oats in diets will cause no reduction in swine performance. The nutritive content of a feed grain is the primary factor in determining its use. This NebGuide discusses the processing of oats for swine diets, gestation diets, lactating diets, starter diets, and growing-finishing diet.

G74-154 Mosquito Control Guide (Revised March 1996), John B. Campbell, David L. Keith, W. Kramer

University of Nebraska-Lincoln Extension: Historical Materials

Mosquitoes are insects belonging to the order Diptera, the same one as flies. Worldwide there are over 3,000 species of mosquitoes, 150 of which are found in the United States. In Nebraska there are fewer than a dozen important species. Distribution of mosquitoes ranges from the Arctic to the Tropical Rain Forests.

The life cycle, control, and impact of mosquitoes common to Nebraska are discussed.

G74-154 Mosquito Control Guide (Revised August 1983), John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

G74-190 Geraniums (Pelargonium) (Revised December 2002), Dale T. Lindgren, Kim Todd, Loren J. Giesler

University of Nebraska-Lincoln Extension: Historical Materials

Geraniums are a popular indoor and outdoor plant. This NebGuide describes how to care for them, including overwintering and treating for diseases.

There are two different groups of plants known as geraniums. The showy, flowering geraniums, normally grown as indoor and outdoor plants in Nebraska, are members of the genus 'Pelargonium.' They are subtropical in origin and are treated as annuals in Nebraska, since they do not overwinter outdoors.

Members of the genus 'Geranium,' which are winter hardy outdoor plants, are usually called the 'hardy geraniums' or cranebills. They are good additions to the perennial landscape border. Hardy geraniums are …

G74-174 Fertilizer Suggestions For Corn (Revised November 2003), Charles A. Shapiro, Richard B. Ferguson, Achim R. Dobermann, Charles S. Wortmann

University of Nebraska-Lincoln Extension: Historical Materials

Fertilizer nutrient requirements for corn are based on expected yield and nutrient levels in the soil. Crop production in Nebraska typically requires applying nitrogen to supplement that available in the soil. Phosphorus is the second most likely nutrient to be deficient in the soil for good corn yields.
