Ec97-1874 Diseases Affecting Grain And Seed Quality In Wheat, John E. Watkins, Larry J. Prentice

University of Nebraska-Lincoln Extension: Historical Materials

Seed-associated diseases of wheat draw considerable attention because they often reduce both grain quality and yield. In addition ergot and scab diseases bring in a third dimension because toxins associated with each present a potentially serious health risk to humans and animals. Yield losses caused by smuts are roughly equal to the percentage of smutted heads in the field; however, losses from black point, scab or ergot are less easily measured. For example, wheat in the soft dough stage that is infected by one of the scab pathogens may still produce plump, good test weight kernels resulting in minimal yield …

Ec95-1873 Cultural Practices That Influence Wheat Diseases, John E. Watkins, Robert N. Klein, Paul C. Hay, Lenis Alton Nelson

University of Nebraska-Lincoln Extension: Historical Materials

The health of a wheatcrop is determined well before the crop is planted. It is often the result of subtle factors in the management history of the field, including varieties, seed quality, seedbed, planting date, residue management and post harvest weed control. Wheat health management practices before the crop is planted must limit, as much as possible, the number of production hazards that must be dealt with after planting. Important diseases influenced by cultural practices include crown and root rot, wheat streak mosaic, soil-borne wheat mosaic, barley yellow dwarf, leaf rust, smut diseases, scab, Cephalosporium stripe and tan spot.

Ec95-1560 Use Of Cultural Practices In Crop Insect Pest Management, Robert J. Wright

University of Nebraska-Lincoln Extension: Historical Materials

This Extension Circular reviews what is known about the effects of rotations, tillage practices, and planting and harvest dates on crop insect management, focusing on major crops in Nebraska.

Before the development of synthetic organic insecticides (pre-DDT era), rotations, tillage practices, planting and harvest dates, and other nonchemical cultural controls were commonly recommended for insect management. Research focused on crop rotation and other cultural practices for insect management. With the development of DDT and later insecticides however, research on nonchemical controls decreased markedly.

With the emergence of the concept of sustainable agriculture in the 1980s, there has been increased emphasis …

Ec93-126 Procedures For Field Demonstrations Of Nitrogen Management Practices, Edwin J. Penas, Richard B. Ferguson, Gary W. Hergert, Charles A. Shapiro, G.D. Binford

University of Nebraska-Lincoln Extension: Historical Materials

Nitrate-nitrogen in groundwater is a major public concern. Agriculture is often targeted as the primary source; however, crop producers are reluctant to reduce the amount of nitrogen they apply in fear of reducing crop yields and profits. Soil testing for nitrate-nitrogen is being promoted as a way to fine-tune or improve nitrogen management, but adoption by producers has been slow. This publication explains how to conduct a field demonstration using scientifically acceptable methods that are practical for on-farm use.

G92-1090 Black Dot Disease Of Potato, Alexander D. Pavlista, Eric D. Kerr, Robert B. O'Keefe

University of Nebraska-Lincoln Extension: Historical Materials

The cause, symptom, disease cycle, influencing factors, effects and control of black dot are described. Black dot of potato, a disease caused by the fungus Colletotrichum coccodes, was recognized in Australia and Europe, then was observed and described in Canada in 1921. Since then this disease has spread to many potato production areas of the United States; its occurrence was first reported in Nebraska in 1988. In the past few years, black dot has been recognized on infected potato tissue from several areas of the state. The increased incidence of black dot in Nebraska may have been favored by high …

Ec91-1771 Windbreaks And Wildlife, Ron J. Johnson, James R. Brandle, Mary M. Beck

University of Nebraska-Lincoln Extension: Historical Materials

Windbreaks can support wildlife that add beauty and pleasure to our lives. They also sustain birds that eat insect pests, improve hunting opportunities, and provide a focal point for family outdoor activities. The world around us would be less appealing without the stimulation--the color, sounds, tracks, and mystery--of wild creatures; windbreaks help wildlife and in some areas are essential to survival of the wildlife we enjoy. You can add wildlife benefits to windbreak plantings whether your main goal is to shelter crops, livestock, roads, or a home or farmstead. This publication provides an overview of windbreaks and wildlife, and gives …

G89-905 Weed Control On Crp Acres (Revised July 1997), Robert N. Klein, Gail A. Wicks, John E. Watkins, Jerry D. Volesky

University of Nebraska-Lincoln Extension: Historical Materials

Establishing perennial grasses on former cropland presents a challenge. Weed control can be accomplished with herbicides, tillage, burning, mowing, and crop competition. The key to weed control is timeliness. Weeds should be controlled on CRP acres to reduce the risk of seeding failure and eliminate possible reseeding costs. Soil moisture must be available for seed germination, seedling emergence, and establishment to be successful in getting stands of grasses and/or legumes. Weeds can quickly and thoroughly consume soil water throughout the upper soil profile and must be controlled to allow grass and legume seedlings to germinate and emerge. In addition, rapid-growing, …

G79-481 Setting A Realistic Corn Yield Goal (Revised January 2004), Achim Dobermann, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

Corn growers need to set a realistic corn yield goal in order to make sound decisions on corn hybrid, seeding rate, fertilizer application, and irrigation need. The goal should be the most profitable yield that can be expected for the particular set of soil, climate, and management practices. Yield goals should gradually increase over time, but cannot exceed the theoretical yield potential. This NebGuide discusses how to set a realistic corn yield goal by acknowledging climatic yield limitations of corn in Nebraska and the yield history in a field.

G78-390 Right Crop Stage For Herbicide Use Alfalfa, Sugarbeets, Soybeans, And Fieldbeans (Revised January 1987), Robert G. Wilson, Alex Martin

University of Nebraska-Lincoln Extension: Historical Materials

If you are using herbicides on alfalfa, sugarbeets, soybeans, or fieldbeans, information in this Guide will help you apply them at the proper time for best weed control with a minimum of crop injury. Proper timing of postemergence herbicides is essential to achieve maximum weed control with minimum crop injury. As field crops grow and mature, their tolerance to herbicides changes. As a general rule, annual and biennial weeds are more susceptible to postemergence herbicides when they are in the seedling stage, becoming increasingly difficult to control as they mature. The grower is thus faced with the problem of when …

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.

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.
