G74-171 Summer Annual Forage Grasses (Revised January 1986), Bruce Anderson, Paul Guyer Jan 1974

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...


G74-142 Harvesting And Preserving Hay Crop Silage, Rick Grant, Rick Stock Jan 1974

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

Historical Materials from University of Nebraska-Lincoln Extension

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.


G74-165 Understand Your Soil Test: Calcium, Magnesium, Boron, Copper, Chlorine, Molybdenum, Delno Knudsen, K.D. Frank Jan 1974

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...

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 ...


G74-113 A Quick Test For Atrazine Carryover (Revised March 1989), Alex Martin, R.N. Stougaard, Patrick J. Shea Jan 1974

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

Historical Materials from University of Nebraska-Lincoln Extension

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 ...


G74-121 Sandbur Control In Field Corn (Revised January 1999), Gail A. Wicks, Robert G. Wilson Jr. Jan 1974

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

Historical Materials from University of Nebraska-Lincoln Extension

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.


G74-186 Cannas, Donald E. Janssen, Don Steinegger Jan 1974

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

Historical Materials from University of Nebraska-Lincoln Extension

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.

A basic knowledge of tree needs and the application of simple management principles are required to produce quality black walnut timber.

Black walnut (Juglans nigra) is a high value timber species. The only way to maximize profit from black walnut plantations is by good timber management. Management practices that increase growth, improve quality and reduce damage, substantially increase profit. A basic knowledge of tree needs and the application of simple management principles are required to produce quality black walnut timber.

Protection, pruning and thinning are the major management activities.


G73-46 Hessian Fly On Wheat, John E. Foster, Gary L. Hein Jan 1973

G73-46 Hessian Fly On Wheat, John E. Foster, Gary L. Hein

Historical Materials from University of Nebraska-Lincoln Extension

This NebGuide discusses the life cycle, control and prevention of the Hessian fly. Plant-safe dates and resistant wheat varieties are also examined.

The Hessian fly, Mayetiola destructor (Say), is not native to the United States, but was probably introduced by Hessian soldiers during the Revolutionary War. This insect was given its common name by Americans because of its damage on Long Island in 1779. The pest has become distributed throughout the United States wheat production areas since then.

The Hessian fly belongs to the family of insects known as gall midges (Diptera: Cecidomyiidae), a group noted for their habit of ...

G73-12 Iris Borer Control, David L. Keith, Frederick P. Baxendale

Historical Materials from University of Nebraska-Lincoln Extension

Scouting, prevention and control of the iris borer.

This insect is the most serious insect pest of iris in Nebraska and is found virtually everywhere in the state. Damage is characterized by dark, streaked, or watery areas and ragged edges on the developing leaves of iris in May and June and extensive destruction of the insides of the rhizomes in July and early August. Examination late in summer will reveal a large white to pinkish caterpillar from 1 1/2 to 2 inches long in the rhizome, usually accompanied by a foul-smelling soft rot.


G73-60 Working With Wood I. Home Drying Lumber (Revised July 1987), Michael Kuhns, Richard Straight Jan 1973

G73-60 Working With Wood I. Home Drying Lumber (Revised July 1987), Michael Kuhns, Richard Straight

Historical Materials from University of Nebraska-Lincoln Extension

Avoid the expense of kiln-dried lumber by processing and drying your own lumber at home.

Anyone who has done much woodworking knows how expensive high quality, kiln-dried, hardwood lumber can be. Even kiln-dried construction lumber is expensive. Besides expense, there also may be problems with finding certain species of wood, highly figured wood, or hardwood boards thicker than one inch (4/4).

One way to avoid these problems is to dry your own lumber. Green, unsurfaced, or unplaned lumber can be obtained from many small sawmills in Nebraska and surrounding states. You may also want to obtain your own logs ...

Historical Materials from University of Nebraska-Lincoln Extension

Successfully growing and harvesting lettuce is the focus of this NebGuide.

Lettuce is an increasingly popular vegetable in the United States. Because it is a basic ingredient in salads, lettuce is eaten more frequently than any other vegetable. Lettuce can be served alone with a variety of dressings or mixed with other fresh vegetables.

Its fresh color and crisp texture serve well as a garnish, and its leaves may be stuffed with fruit, cheese, seafood, poultry, ham, or egg salads. Although usually consumed fresh, leaf lettuce and chopped green onions "wilted" with warm vegetable oil and vinegar make a pleasing ...

Bagworms can damage juniper, arborvitae, pine, and spruce. Description, life history, and control are discussed in this publication.

The bagworm is native to the United States and is found in eastern Nebraska. Bagworms feed on many species of trees and shrubs, but are most common on junipers. They are rarely a serious problem on deciduous trees, except when larvae move away from evergreens.


G73-14 Grain Processing For Feedlot Cattle, Paul Q. Guyer Jan 1973

G73-14 Grain Processing For Feedlot Cattle, Paul Q. Guyer

Historical Materials from University of Nebraska-Lincoln Extension

Several changes have occurred in the cattle feeding business which have focused attention on grain processing. The first of these was, the arrival of big feedlots provided an opportunity to use larger and more sophisticated processing equipment at reasonable cost per ton of feed produced. Also, the need to minimize feed separation and digestive disturbances encouraged the use of more sophisticated methods of processing.

A second development that is now focusing attention on grain processing is the rapidly increasing costs of equipment, fuel and labor involved in grain processing. In recent years, these have been increasing more rapidly than the ...


Rb160 Pink Rot Of Potatoes Caused By Phytophthora Erythroseptica Pethyb., R. W. Goss Jan 1949

Rb160 Pink Rot Of Potatoes Caused By Phytophthora Erythroseptica Pethyb., R. W. Goss

Historical Materials from University of Nebraska-Lincoln Extension

During the summer of 1943 reports were received of rotted tubers occurring in fields of early potatoes in central Nebraska. The fact that the tuber rot was present at harvest time and was associated with the early death of the plants rather than occurring as a postharvest disease indicated the presence of a disease factor previously unreported in Nebraska.
