Management Of Merino Weaners For Optimum Production, Patricia Harper, Keith Croker, Danny Roberts

Bulletins 4000 -

Sheep mortality during the first year of life is a large problem on many farms and poses a significant animal welfare issue for Australian agriculture. Post weaning mortality is estimated to cost the Australian sheep industry more than $89 million annually through reduced income, poor productivity and increased management expenses (Sackett et al. 2006).

A high mortality rate among weaners reduces the number of surplus animals available for sale and the number of potential breeding replacements. This, in turn, affects the selection intensity for desirable traits and the flock’s rate of genetic improvement.

Ill thrift and poor growth of weaner …

Severity Of Root Rot In Mature Subterranean Clover And Associated Fungal Pathogens In The Wheatbelt Of Western Australia, Tim Scanlon, Tiernan A. O’Rourke, Martin J. Barbetti, Megan H. Ryan, Len J. Wade, Alan C. Mckay, Ian T. Riley, Hua Li, Krishnapillai Sivasithamparam

Journal articles

Pasture decline is considered to be a serious challenge to agricultural productivity of subterranean clover across southern Australia. Root disease is a significant contributing factor to pasture decline. However, root disease assessments are generally carried out in the early part of the growing season and in areas predominantly sown to permanent pastures. For this reason, in spring 2004, a survey was undertaken to determine the severity of root disease in mature subterranean clover plants in pastures located in the wheatbelt of Western Australia. DNA-based soil assays were used to estimate population density in the soil of a variety of soil-borne …

INTSORMIL Scientific Publications

Grain sorghum (Sorghum bicolor (L.) Moench) is a major crop in many parts of Africa and is noted for its versatility and diversity. It is adapted over a wide range of precipitation and temperature levels and is produced at sea level to above 2000 m altitude. In eastern and southern Africa, it is primarily a crop of resource-poor, small-scale farmers and is typically produced under adverse conditions such as low input use and marginal lands. There are numerous biotic and abiotic constraints to production. The grain and stover are used in many different ways with localized preferences. Much information …

Good Agricultural And Handling Practices For Grapes And Other Fresh Produce, Pamela L. Brady, Justin R. Morris

AAES Research Reports and Research Bulletins

In recent years consumption of fresh fruits and vegetables has increased dramatically. This trend has increased the amount of produce being purchased at farmer’s markets, road-side stands, and neighborhood markets since consumers say they feel that the direct contact with growers at these markets makes them better able to assess the quality and safety of the produce. This buying trend has opened new markets to small- and medium-sized farms, which sell at these local outlets.

Characterizing The Variability Of Physical And Chemical Properties Across The Soil Individuals Mapped As Amy Silt Loam Soils In Southeastern Arkansas, B. Bhandari, Robert L. Ficklin

Journal of the Arkansas Academy of Science

Knowledge of physical and chemical properties of soil is relevant for landowners, researchers, and foresters, so that appropriate crop species and management practices to maximize site productivity can be selected. In addition to issues of plant productivity, the need for assessing soil properties has been expanded due to public interest in determining the consequences of management practices on soil quality relative to sustainability of crop ecosystem functions. The USDA-Natural Resources Conservation Service (NRCS) delineated soil mapping units to provide information about physical and chemical properties of soil in each soil series. However, soil mapping units do not provide details about …

Diagnosing Crop And Pasture Problems With Detective Doug, Doug Sawkins

Bulletins 4000 -

There are numerous publications for diagnosing crop and pasture growth problems. Although they are excellent for experienced people, they can be time consuming and possibly misleading for the less experienced.

Many guidebooks assume that the user has already decided that their problem falls into the category covered by their particular guidebook, for example, a disease, pest or herbicide problem.

Guidebooks are often based on plant symptoms. However, in the field, symptoms vary and different problems can have similar symptoms.

This bulletin presents a problem diagnosis method that uses plant symptoms and paddock clues. It can be used to draw up …

Antibiotic Use In Animal Production: Environmental Concerns, Teshome H. Regassa, Richard K. Koelsch, Charles S. Wortmann, Richard F. Randle, Akwasi A. Abunyewa

Department of Agronomy and Horticulture: Faculty Publications

Introduction

Antibiotic1 use in animal production has led to improved feed use efficiency and increased growth rates. In turn, these resulted in reduced food production costs and reduced excrement of manure nutrients which may cause pollution problems.

On the other hand, antibiotic use leads to antibiotic resistance and a possible reduction in effectiveness of treatment options for both animals and humans. This publication addresses these issues.

Disease-causing microorganisms2, including bacteria,are the most diverse and numerous organisms on earth. Diverse in their habitat, environmental adaptation, and mechanisms of reproduction, they have short generations with high multiplication rates. Such characteristics help develop …

Ethylene Synthesis And Sensitivity In Crop Plants, Joseph F. Romagnano

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The gaseous plant hormone ethylene is a small molecule that regulates developmental change. Research was conducted in three areas: sensitivity, synthesis, and alterations to synthesis. Vegetative pea plants were more sensitive than radish plants to atmospheric ethylene. Light intensity did not affect ethylene sensitivity. Ethylene synthesis rates were measured for unstressed cotton, corn, soybean, and tomato plants. The per-plant ethylene synthesis rate ranged from 0.1-80 pmol plant^-1 s^-1. However, when normalized to net photosynthetic rate, this range was 1-4 µmol of ethylene synthesis per mol of CO₂ uptake. Diurnal cycles in ethylene synthesis were present in …

Growing Wild: Crested Wheatgrass And The Landscape Of Belonging, Lafe Gerald Conner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Crested wheatgrass arrived in North America at the turn of the twentieth century through the foreign plant exploration missions sponsored by the United States Department of Agriculture. During the first two decades of the new century, scientists tested the grass at agricultural experiment stations. They determined it was useful for grazing and particularly valuable because it could grow in drought conditions with little or no care and would continue to produce high quality feed even after several years of heavy use. Beginning in the 1930s federally sponsored land utilization and agricultural adjustment programs sponsored the use of crested wheatgrass for …

In Vitro And In Vivo Techniques For Screening New Natural Product-Based Fungicides For Control Of Strawberry Anthracnose, Maritza Abril

Dissertations

Seven plant pathogenic fungi (Botrytis cinerea, Colletotrichum acutatum, C. fragariae, C. gloeosporioides, Fusarium oxysporum, Phomopsis obscurans, and P. viticola) valuable in screening fungicide efficacy were tested. Optimal and reproducible conditions for germination of these selected fungi were established by incorporating Roswell Park Memorial Institute 1640 (RPMI) as a medium of known composition and washing conidia to remove innate germination inhibitors. This step reduced average fungal germination times between 3.5 h and 21.2 h. The natural product-based fungicide, sampangine, seven sampangine analogs (4-bromo-sampangine, 4-methoxysampangine, benzo[4,5]sampangine, liriodenine Mel AMC-XIII-103, onychine, cryptolepine, and liriodenine CDH-II-37), plus seven conventional fungicides (benomyl, captan, cyprodinil, fenbuconazole, …
