Assessing The Relative Utility Of Models Of Vegetation Dynamics For The Management Of Sagebrush Steppe Rangelands, Paul E. Hosten

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The literature, long-term temporal data sets, and spatial data points surrounding livestock watering pints within rangeland communities wearer used to examine common assumptions and concepts used in models of vegetation dynamics. Of the stability concepts examined, the constancy concept was invalidated using long-term relict area data, whereas long-term data following disturbance indicated that sagebrush-dominated areas could be considered as resilient under circumstances examined. Pioshpere as well as relict and post-disturbance data indicated that the individualistic notion of vegetation change was favored. Species showing the most predictability (based on repeatability of abundance curves, and spatial and temporal serial correlations) were sagebrush …

Recent yield losses from the disease have exceeded 50 percent in some areas.

Ec95-272 Nutrition Management Of Pregnant And Lactating Mares, Kathleen P. Anderson

University of Nebraska-Lincoln Extension: Historical Materials

Serious horse producers are concerned about their mares' reproductive performance and ability to mother strong, healthy foals. Economic survival often hinges on mares foaling early in the year, rebreeding quickly and nursing a growing foal that develops soundly. While achieving these goals in a herd of brood mares is dependent upon many factors, nutritional well-being is one important part of an effective brood mare operation.

Brood mares have specific nutritional requirments that differ from other classes of horses. There are differences both in the amount of feed mares need and in the nutrient concentration needed in taht feed. Therefore, the …

Nf95-219 Common Ground: State Conservation Reserve, William Miller

University of Nebraska-Lincoln Extension: Historical Materials

The Conservation Reserve Program (CRP) has been a popular part of the federal farm program for the past several years because it contributes to farm income, soil conservation, and wildlife habitat. Landowners have found the annual payments for enrolling land in the CRP to be a financially attractive alternative to producing crops. Higher commodity prices due to fewer crop acres has been an additional benefit to landowners. Environmentalists have been pleased with the lower soil losses from the land and the improved stream environment associated with the CRP. Wildlife advocates are strong supporters of the CRP. For example, the Wildlife …

Nf95-218 Conjunctive Use Policy Options, William Miller

University of Nebraska-Lincoln Extension: Historical Materials

Background

The hydrologic cycle controls water available for use. Rainfall, evaporation, runoff, percolation, and transpiration combine to influence the water available at a specific location at a particular point in time. The speed at which water moves among stages in the hydrologic cycle and the amount of time it spends in storage at any stage affects water availability to users. The conjunctive use issue refers to the portion of the hydrologic cycle where groundwater and surface water interface and influence each other.

Users who couldn't depend on an irregular flow of water over time developed systems that modify the variable …

G95-1224 How To Write A Dairy Job Description, Jeffrey F. Keown, Erin Marotz

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide leads you through the process of developing a job description for positions in the dairy industry.

As dairy herd sizes continue to increase and the management of the herd can no longer be solely a family responsibility, labor management becomes more important.

There are several areas to consider when going from a family operation to one that requires hiring off-the-farm labor. The most important point to consider is writing a job, or position, description for each employee you plan to hire, or currently employ in the dairy operation. A detailed job description can help eliminate individuals who will …

G94-1206 Biosecurity And Disease Prevention For The Ratite Grower, Eva Wallner-Pendleton

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide acquaints the ratite grower with management techniques that can help reduce the likelihood of disease introduction and spread on the farm.

Introduction

Infectious diseases always concern people who raise animals, including ratite and poultry producers. In general, the larger the number of animals concentrated in a given area, the more potential there is for diseases to occur. This potential is greatly increased if new animals are frequently introduced. Other ways diseases are spread include allowing visitors near the animals, raising multiple ages close to each other or allowing contact with other species.

As the ratite industry matures, farms …

G94-1208 Managing The Alfalfa Weevil, Stephen D. Danielson, Thomas E. Hunt, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

The identification and life cycle of the alfalfa weevil are discussed along with scouting techniques, economic thresholds, and other integrated pest management tactics.

The alfalfa weevil is the primary insect pest of alfalfa in Nebraska. Management is essential to reduce crop losses, particularly during years when weevil infestation is high. Because there also are years when weevil damage is economically unimportant, it is necessary for growers to become familiar with sampling procedures, management guidelines, and control recommendations so control techniques are not used unnecessarily.

G94-1207 Scab Of Wheat, John E. Watkins, Ben Doupnik, Jr.

University of Nebraska-Lincoln Extension: Historical Materials

The identification of and disease cycle of wheat scab is described along with its management. Guidelines for using wheat contaminated with vomitoxin also are included.

Scab or Fusarium head blight is an important disease of wheat, barley, oats, rye and wheatgrasses. Scab manifests itself by the premature death or blighting of spikelets in the wheat head. Direct yield losses are often minor, but can be higher than 50 percent in severely infected fields. The economic significance is magnified by the possibility that the low quality, shriveled grain also can become contaminated by mycotoxins (e.g. vomitoxin, zearalenone).

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the life cycle of the army cutworm and pale western cutworm, and provides recommendations for management.

The army cutworm, Euxoa auxiliaris, and the pale western cutworm, Agrotis orthogonia, are sporadic pests that are distributed throughout the Great Plains. The army cutworm can be found throughout Nebraska, but is more common in the western half of the state. Because of the drier environment, the pale western cutworm is found only in the western third of Nebraska. Both cutworms can feed on a vast array of crops and weeds. Their major economic impact is limited to winter …

G93-1158 Questions And Answers About Atrazine, Fred Roeth, S.D. Comfort

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide addresses some of the current concerns about atrazine and water quality. Included are some questions and answers about atrazine regarding toxicity, EPA guidelines, presence in water supplies, weed resistance and best management practices. What is atrazine? Atrazine is a herbicide that selectively controls broadleaf (dicot) weeds, such as pigweed, cocklebur, velvetleaf and certain grass weeds in fields of corn and sorghum. Selective control means that the target weeds are controlled, with little or no injury to the crop. Atrazine is well tolerated by actively growing corn and sorghum, which absorb and metabolize the herbicide and thereby detoxify it.

For example, CD's and EE savings bonds are considered safe investments because the probability that the actual return on …

G93-1136 Potato Leafhopper Management In Alfalfa, Stephen D. Danielson, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to detect and manage potato leafhoppers to minimize alfalfa damage.

The potato leafhopper is capable of causing serious damage to alfalfa in Nebraska. This insect overwinters in the gulf states and migrates northward in the spring, usually in April or early May. During the summer months, several generations develop while feeding primarily on legumes such as alfalfa and clover. Although an occasional host, soybeans rarely suffer economic damage, particularly with the pubescent (i.e. hairy) soybean varieties that are commonly grown today. Infested potatoes also can sustain economic damage from this insect. Generally, the potato leafhopper is …

G93-1167 Spider Mite Management In Corn And Soybeans, Robert J. Wright, Ronald C. Seymour, Leon G. Higley, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the two common spider mites found in Nebraska corn and soybeans, their natural enemies and management.

Two species of spider mites, the Banks grass mite and twospotted spider mite, commonly feed on Nebraska corn. Banks grass mites (BGM) feed almost exclusively on grasses, including corn and sorghum. Twospotted spider mites (TSM) not only feed on many species of grasses, but also on soybeans, fruit trees and a variety of vegetables and ornamental plants. Although these two species are somewhat similar in appearance, they differ in several biological characteristics and in their susceptibility to pesticides.

Banks grass mites …

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.
