Agriculture reports

A computer program called NPDECIDE has been developed by the Western Australian Department of Agriculture to assist with decisions relating to the use of phosphorus fertiliser on cereal crops. NPDECIDE functions by estimating the response of the crop to combinations of nitrogen and phosphorus fertilisers, and by indicating the likely profit from the use of these materials. In order to carry out this task, NPDECIDE must be able to calculate the availability to the growing plants of nitrogen from the fertilisers and from organic material in the soil.

Paddock Sampling For Management Of Annual Ryegrass Toxicity, Ian Riley

Journal of the Department of Agriculture, Western Australia, Series 4

Annual ryegrass (Lolium rigidumJ seedheads containing corynetoxins, a group of bacterially produced antibiotics, are poisonous to livestock. Animals that eat affected ryegrass develop annual ryegrass toxicity (ARGT), suffer convulsive staggers and die within a few days of eating a lethal dose. ARGT is characterised by high death rates, especially where pastures are not known to be affected and where stock-owners are not expecting the problem. Fortunately, there are commercial tests that determine the levels of ARGT organisms in the paddock and the risk of getting the disease. These tests will help farmers plan their cropping and pasture programs for the …

Land Use History: Universal Forest Products Mill Site, Susie Van Kirk

Susie Van Kirk Papers

A history of land use in post-settler Humboldt County, spanning from 1850-1992. This report discusses the process of industrialization in Humboldt County, focusing on the Arcata Creamery and the Arcata Mill. This report includes a history of how the logging, milling, and agriculture industries expanded and created the need for industry such as the Creamery and the Mill.

Nf92-67 Nutrition And The Athlete: Weight Control For Wrestlers, Linda S. Boeckner

University of Nebraska-Lincoln Extension: Historical Materials

The American College of Sports Medicine warns that weight cutting through a combination of food restriction, fluid deprivation and dehydration can be harmful Restrictions of food and/or fluid can hinder normal growth and development in young athletes, impair performance, and endanger the wrestler's health. Coaches and trainers must consider the long-term needs of their student athletes.

G92-1069 The Poinsettia, Jay Fitzgerald, Don Steinegger

University of Nebraska-Lincoln Extension: Historical Materials

Growing poinsettias so that they rebloom is easier if you understand and follow some basic horticultureicultural and pest management procedures.

Poinsettias are the most popular decorative plants for the Christmas and New Year holiday seasons. The newer cultivars often remain colorful until spring and do not have to be discarded when they finish blooming. Following a few basic principles can bring the plants back into full bloom.

The poinsettia Euphorbia pulcherrima is a native to the area around Taxco, Mexico, and was introduced to the United States by Joel R. Poinsett, the first United States ambassador to Mexico. Poinsettia or …

Ec92-1245 Buffalograss: A Warm-Season Native Grass For Turf, S.A. Deshazer, Terrance P. Riordan, Frederick P. Baxendale, Roch E. Gaussoin

University of Nebraska-Lincoln Extension: Historical Materials

Buffalograss is a native grass species which has prospered on the Great Plains for centuries. Both cyclic and prolonged droughts have challenged it to evolve water use efficiency and sod forming ability. People are considering this short, fine-leaved prairie grass for an ecologically sound and energy efficient turf.

G92-1108 Evaluating Corn Rootworm Soil Insecticide Performance, J. F. Witkowski, Lance J. Meinke, Gary L. Hein, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes a technique used to evaluate the relative performance of insecticides in protecting corn roots from feeding damage by corn rootworm larvae.

Insecticides applied at planting or cultivation time are commonly used in continuous corn to protect the roots from damage by western and northern corn rootworms.

Measuring the relative performance of these insecticides in protecting corn roots from rootworm larval damage is important.

G92-1112 Lice Control On Cattle, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

Identifying and controlling lice on cattle both are covered here.

Cattle lice may be the most underestimated livestock insect in terms of economic losses. The USDA estimates that U.S. livestock producers lose $125 million a year to cattle lice.

Heavy louse populations cause lowered milk production, loss of flesh, stunted growth, general unthriftiness and anemia. "Chronic" or "carrier" cows may abort due to louse-induced anemia. During severe winters, louse-infested animals are more susceptible to respiratory diseases.

G92-1094 Controlling External Swine Parasites, John B. Campbell, Barbara Straw

University of Nebraska-Lincoln Extension: Historical Materials

Mixing, safety, restrictions, and precautions for insecticides used to control external swine parasites.

Hog Lice and Mange Mites

External parasites of swine include the hog louse and two species of mange mites (the common itch mite and the less common hog follicle mite). Excessive scratching and rubbing by pigs nearly always indicate an infestation of hog lice or mange mites.

Hog lice and mange mites infest a high percentage of swine slaughtered at Midwest slaughter plants.

Ec92-270 Conducting Pig Feed Trials On The Farm, Duane Reese, Walter W. Stroup

University of Nebraska-Lincoln Extension: Historical Materials

The purpose of this publication is to provide fundamental information that must be understood before attempting to conduct a feed trial. The concepts and procedures described here are valid for most situations involving a comparison of two feeds. Any trial involving more than two feeds raises issues that are beyond the scope of this publication. Those issues are covered in university statistics courses on design and analysis of experiments.

We suggest that pork producers adopt a "best cost" feeding program tailored to the operation and based on sound nutritional principles. Feed cost per pound of gain is a major item …

G92-1106 Controlling Rats, Scott E. Hygnstrom, Dallas R. Virchow

University of Nebraska-Lincoln Extension: Historical Materials

Ways to recognize rat problems and control rats are covered here.

The Norway rat (Rattus norvegicus) (also known as the common brown rat) is a destructive pest. Found in and around towns and farms throughout Nebraska, these rodents eat and contaminate large amounts of feed, damage structures by their gnawing and burrowing, and spread diseases that affect livestock and humans.
