United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Beef carcass sponge samples collected from July to August 1999 at four large processing plants in the United States were surveyed for the presence of non-O157 Shiga toxin-producing Escherichia coli (STEC). Twenty-eight (93%) of 30 single-source lots surveyed included at least one sample containing non-O157 STEC. Of 334 carcasses sampled prior to evisceration, 180 (54%) were found to harbor non-O157 STEC. Non-O157 STEC isolates were also recovered from 27 (8%) of 326 carcasses sampled after the application of antimicrobial interventions. Altogether, 361 non-O157 STEC isolates, comprising 41 different O serogroups, were recovered. O serogroups that previously have been associated with …

Relationships Between Blueberry Flower Age, Pollination, And Conidial Infection By Monilinia Vaccinii-Corymbosi, Jeffery S. Lehman, Henry K. Ngugi, Harald Scherm
Relationships Between Blueberry Flower Age, Pollination, And Conidial Infection By Monilinia Vaccinii-Corymbosi, Jeffery S. Lehman, Henry K. Ngugi, Harald Scherm
Biology and Earth Science Faculty Scholarship
Monilinia vaccinii-corymbosi infects open blueberry flowers via the gynoecial pathway, leading to mummification of the developing fruit. To determine the effect of flower age on infection, stigmata were inoculated with conidia of M. vaccinii-corymbosi between 0 and 5 days after anthesis, fungal growth rates through the stylar canal were measured in detached flowers in the laboratory, and fruit disease incidence was determined in plants grown in the greenhouse. Hyphal growth rates were greatest in flowers inoculated on the day of anthesis, declined linearly with increasing flower age at inoculation (r = 0.921; P < 0.0001; n = 12), and were unaffected by the presence or absence of pollen applied at the time of inoculation. In greenhouse-grown plants, the percentage of infected fruit decreased exponentially with increasing flower age at inoculation (R = 0.878; P = 0.0057; n = 10), with disease incidence ranging from 76.4% for flowers inoculated on the day of anthesis to 15.5% for those inoculated 4 days later. Fruit disease incidence in the greenhouse was linearly correlated with hyphal growth rates in detached flowers (r = 0.985; P < 0.0001; n = 9), justifying the use of detached flowers when investigating gynoecial infection by M. vaccinii-corymbosi. In separate experiments, the effects of timing and sequence of pollination and inoculation on hyphal growth rates through the stylar canal and on disease incidence were investigated. Application of pollen to detached flowers 1 or 2 days before inoculation reduced hyphal growth rates by between 14.0 and 42.9% compared with flowers that received pollen and conidia simultaneously. Similarly, reductions in fruit disease incidence by between 9.5 and 18.3% were observed on greenhouse-grown plants for pollination-to-inoculation intervals ranging from 1 to 4 days. These results document that newly opened flowers are most susceptible to infection by M. vaccinii-corymbosi and that fruit disease incidence is reduced if pollination occurs at least 1 day before inoculation. Strategies that lead to early pollination of newly opened flowers may be useful for managing mummy berry disease in the field.

Impact Of The Agricultural Sector On The Arkansas Economy, H. L. Goodwin Jr., Jennie Popp, Wayne Miller, Gina Vickery, Z. Clayton-Niederman
Research Reports and Research Bulletins
Agriculture historically has been one of the primary sectors of the Arkansas economy. Agriculture is defined as the sum of agricultural, forestry, and fisheries production and processing activities unless otherwise specified. Not only does agriculture contribute to the economy through direct agricultural production and added value processing, it also plays an important role through the economy’s other sectors. Utilizing data from the United States Bureau of Economic Affairs and the State of Arkansas, the economic impact of agriculture on the Arkansas economy was estimated for the latest year available, 1999. Gross State Product (GSP) information for Arkansas was compared with …

Summaries Of Arkansas Cotton Research In Progress In 2001, Derrick M. Oosterhuis
Arkansas Agricultural Experiment Station Research Series
Cotton yields in Arkansas increased steadily during the eighties, but in recent years there has been a leveling off. Of more significance, however, is that extreme year-to-year variability in yields has occurred in the last decade, which is a major point of concern with cotton producers. It has been suggested that this may be related to extreme weather conditions during the boll development period in July and August. Average maximum temperatures in the 2001 season were a few degrees above normal. Recent research in Arkansas has indicated that elevated night temperatures during boll development may be a major contributory factor …

Pb1721 Irrigation Cost Analysis Handbook, The University Of Tennessee Agricultural Extension
Field & Commercial Crops
Irrigation is a risk management tool. The risk of yield reduction due to drought is minimized with irrigation, because moisture can be added to the soil to match the water requirements of the crop. Irrigation is also a major capital investment. The yield produced under irrigation must be sufÞ cient to produce a positive return on the investment.
This handbook is intended to assist users in determining the economics of investing in irrigation at their location. All irrigation systems are unique. Many factors are used to estimate the cost of irrigation, and each of these factors will vary with location. …
Understory Species Patterns And Diversity In Old-Growth And Managed Northern Hardwood Forests, Robert M. Scheller, David J. Mladenoff
Understory Species Patterns And Diversity In Old-Growth And Managed Northern Hardwood Forests, Robert M. Scheller, David J. Mladenoff
Environmental Science and Management Faculty Publications and Presentations
Forest management can significantly affect both the diversity and spatial patterning of understory vegetation. However, few studies have considered both diversity and spatial patterning at a stand scale. Our objective was to evaluate the effects of forest management on understory plant communities in northern hardwood forests and assess the processes governing differences in species composition, diversity, and spatial patterns. We sampled understory vegetation (all speciestall) and percentage of light transmission levels in three forest types in 12 mesic northern hardwood stands in northern Wisconsin and the Upper Peninsula of Michigan, USA: old-growth, undisturbed forests; even-aged forests resulting from clearcut logging …

Sustainability Issues For Agriculture In Western Australia, Anne Bennett, Ross Kingwell, Ross George
Sustainability Issues For Agriculture In Western Australia, Anne Bennett, Ross Kingwell, Ross George
All other publications
Agriculture has been and will continue to be a major component of economic activity in several regions in Western Australia, and agricultural communities will remain an important part of the social fabric and landscape of the State. Promoting the sustainability of agriculture is likely to produce three main outcomes: vibrant rural communities; profitable agricultural systems; and conservation of the natural environment. This paper describes briefly the main challenges to the sustainability of agriculture and outlines some means of responding to the challenges: market-based approaches; agricultural and environmental research and development; accelerated adjustment; and global and national policy initiatives.

Ontogeny of the invasion process by Colletotrichum acutatum and C. fragariae was studied on petioles and stolons of the strawberry cultivar Chandler using light and electron microscopy. The invasion of host tissue by each fungal species was similar; however, each invasion event occurred more rapidly with C. fragariae than with C. acutatum. Following cuticular penetration via an appressorium, subsequent steps of invasion involved hyphal growth within the cuticle and within the cell walls of epidermal, subepidermal, and subtending cells. Both species of fungi began invasion with a brief biotrophic phase before entering an extended necrotrophic phase. Acervuli formed once …

Viscoelastic Properties And Changes In Pasting Characteristics Of Trifoliate Yam (Dioscorea Dumetorum) Starch After Harvest, Emmanuel Ohene Afoakwa, Samuel Sefa-Dedeh
Professor Emmanuel Ohene Afoakwa
Studies were conducted on the viscoelastic properties, as well as the changes in pasting characteristics, of trifoliate yam, Dioscorea dumetorum, starch during post-harvest hardening of the tubers. A 3x4 factorial experiment with blanching treatment time (0, 15 and 30 s) and storage time (0, 12, 24 and 36 h) as the respective variables was performed. The samples were evaluated for pasting temperature, viscosity at 95 _C, viscosity at 95 _C-Hold, viscosity at 50 _C and viscosity at 50 _C-Hold, as well as their changes during storage of the tubers, to determine the starch behaviour of the D. dumetorum tubers during …

Cauliflowers In Western Australia - An Industry Plan, Paul Mattingley
Agriculture reports
The Western Australian cauliflower industry is largely centered around the south-west of the State which, with its cool winter climate and medium to heavy loam soils is well suited to year round cauliflower production and accounts for 77% of State’s output. The Shire of Manjimup alone accounts for about 60% of the State’s cauliflower production. The second most significant region is the Swan Coastal Plain which has lighter soils, and a warmer climate. The Swan Coastal Plain is also suitable for year round production. Market analysis indicates that West Australian cauliflower, whilst appearing more expensive than produce from the Eastern …
