The Chickpea Book : A Technical Guide To Chickpea Production, Stephen Loss, Neil Brandon, K H M. Siddique

Bulletins 4000 -

The area of chickpea production in Australia has expanded rapidly in recent years especially in south-western Australia. This has been partly brought about by the keen interest of farmers and a concerted research effort and industry development by Agriculture Western Australia, The Centre for Legumes in Mediterranean Agriculture (CLIMA) and other institutions, in partnership with the Grains Research and Development Corporation and other industry funding bodies. Private consultants, grain traders and other industry groups have also contributed to the expansion of the industry.

Much of the local knowledge generated by these research and development projects has been published in various …

The Mortenson Ranch: Cattle And Trees At Home On The Range. A Restoration Guidebook, Susan E. Boettcher, W. Carter Johnson, Scott Kronberg, F. Robert Gartner, Clarence Todd, Jeff Mortenson, Scott Fausti

Natural Resource Management Faculty Publications

Early agriculture on western rangeland met with little success and resulted in serious consequences including soil erosion, loss of native woodlands and wildlife, and economic ruin. The Mortenson family in Stanley County, South Dakota, has been engaged in restoring degraded rangeland on their ranch for more than 50 years. Their primary goal has been to return the land to its condition prior to white settlement while maintaining a profitable cattle ranching operation. In recent years the ranch has served as a model of successful ranching based on a conservation ethic. This guidebook summarizes the restoration techniques and grazing regime used …

Escherichia Coli O157:H7 Requires Intimin For Enteropathogenicity In Calves, Evelyn A. Dean-Nystrom, Brad T. Bosworth, Harley W. Moon, Alison D. O’Brien

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Enterohemorrhagic Escherichia coli (EHEC) strains require intimin to induce attaching and effacing (A/E) lesions in newborn piglets. Infection of newborn calves with intimin-positive or intimin-negative EHEC O157: H7 demonstrated that intimin is needed for colonization, A/E lesions, and disease in cattle. These results suggest that experiments to determine if intimin-based vaccines reduce O157:H7 levels in cattle are warranted.

Growth Responses Of Warm-Season Tall Grasses To Dormant Season Management, Walter H. Schacht, Alexander J. Smart, Bruce Anderson, Lowell E. Moser, Richard J. Rasby

Department of Agronomy and Horticulture: Faculty Publications

A study on Conservation Reserve Program (CRP) land was established in southeastern Nebraska to determine the effect of dormant-season management on subsequent-year growth rates and yields of tallgrasses. The purpose of the management practices was removal of standing dead material and litter that negatively impact plant growth and grazing efficiency. Treatments consisted of a control with no residue manipulation and 5 residue manipulation practices including (1) October shredding and leaving residue; (2) October haying; (3) October intensive grazing; (4) March intensive grazing; and (5) spring prescribed burning. The study was conducted in 1994195 and 1995/96 on a switchgrass (Panicum …

Winter Macroinvertebrate Communities In Two Montane Wyoming Streams, Christopher M. Pennuto, Frank Denoyelles Jr., Mark A. Conrad, Frank A. Vertucci, Sharon L. Dewey

Great Basin Naturalist

Macroinvertebrate communities were examined on 4 winter dates over a 4-yr period in 2 high-altitude Rocky Mountain streams to document overwintering assemblages potentially experiencing spring acid pulses. Taxa richness values were comparable to other published lists for alpine and montane stream systems despite the fact that most literature reflected summer collections. Mean benthic density ranged from 1406 to 19,734 organisms/m², and drift rates ranged from 0 to 1740 organisms/100 m³. Benthic collections showed higher taxa richness than drift collections while the Ephemeroptera and Plecoptera occurred in greater proportions in drift than in benthos. The Nemouridae (Plecoptera), …

Morphological Development Of 2 Warm-Season Grasses In The Nebraska Sandhills, J. R. Hendrickson, Lowell E. Moser, K. J. Moore, Steven S. Waller

Department of Agronomy and Horticulture: Faculty Publications

Morphological development of grasses has numerous implications to rangeland management including the timing and amount of herbivory. The objective of this study was to quantify the developmental morphology of prairie sandreed [Calamovilfa longifolia (Hook.) Scrihn.] and sand bluestem [Andropogon gerardii var. paucipilus (Nash) Fem.] tiller populations. Tier populations of these 2 grasses were studied for 2 years in the Nebraska Sandhills. Plant development was evaluated using a growth staging system which quantifies the development of tiller populations. A morphological growth index for each species was calculated from either the weighted average of tiller numbers reported as mean stage …

Prediction Of Leaf:Stem Ratio In Grasses Using Near Infrared Reflectance Spectroscopy, Alexander J. Smart, Walter H. Schacht, Jeffrey F. Pedersen, Daniel J. Undersander, Lowell E. Moser

Department of Agronomy and Horticulture: Faculty Publications

Leaf:stem ratio of grass stands is an important factor affecting diet selection, quality, and forage intake. Estimates of leaf:stem ratios commonly are based on a labor intensive process of hand separating leaf and stem fractions. Near infrared reflectance spectroscopy (NIRS) has been used successfully to predict forage quality and botanical composition of vegetation samples. The objective of this study was to evaluate the use of NIRS to predict leaf:stem ratios in big bluestem (Andropogon gerardii Vitman), switchgrass (Punicum virgatum L.), and smooth bromegrass (Bromus inermis Leyss.). A total of 72 hand-clipped samples of each species was taken …

Identification Of A Family Of Zinc Transporter Genes From Arabidopsis That Respond To Zinc Deficiency, Natasha Grotz, Tama Fox, Erin Connolly, Walter Park, Mary Lou Guerinot, David Eide

Dartmouth Scholarship

Millions of people worldwide suffer from nutritional imbalances of essential metals like zinc. These same metals, along with pollutants like cadmium and lead, contaminate soils at many sites around the world. In addition to posing a threat to human health, these metals can poison plants, livestock, and wildlife. Deciphering how metals are absorbed, transported, and incorporated as protein cofactors may help solve both of these problems. For example, edible plants could be engineered to serve as better dietary sources of metal nutrients, and other plant species could be tailored to remove metal ions from contaminated soils. We report here the …

Polymerase Chain Reaction Detection And Phylogenetic Characterization Of An Agent Associated With Yellow Vine Disease Of Cucurbits, Francisco J. Avila, Benny D. Bruton, Jacqueline Fletcher, J. L. Sherwood, Sam D. Pair, Ulrich Melcher

Department of Plant Pathology: Faculty Publications

Diagnosis of yellow vine disease (YVD) in cucurbits, an important disease in the south-central United States, relies on external symptom appearance, phloem discoloration, and the presence of bacterium-like organisms (BLOs) in phloem. Polymerase chain reaction (PCR) amplification of BLO nucleotide sequences was explored as a means to improve diagnostic techniques. PCR, using a primer pair based on sequences of the citrus-greening BLO, amplified a 0.15-kilobase (kb) fragment from the DNA of symptomatic plants, but not from that of asymptomatic plants. Its nucleotide sequence suggested that the DNA amplified was of prokaryotic origin. A primer pair, designed to amplify nonspecific prokaryotic …

Opportunities For Growing Short-Rotation Woody Crops In Agroforestry Practices, Gary A. Kuhn, W. J. Rietveld

Agroforestry Notes (USDA-NAC)

Technologies are readily available for growing hybrid poplars and willows in block plantings as short-rotation woody crops (SRWC) for fuel and fiber. SRWC species and technologies can also be incorporated into agricultural systems as agroforestry practices. Examples are windbreaks, living snowfences, “timberbelts”, riparian buffer strips, and wastewater treatment plantings. Fast growth, convenient propagation (see AF Note - 11), and compatibility with conventional farming methods make SRWC suitable for use in agroforestry practices to provide multiple benefits such as solid wood and wood fiber products, water quality improvement, crop and soil protection, wildlife habitat, and buffers for agricultural/community interfaces.

Report On Degradation In The Southern River / Wungong Catchment. Perth, Western Australia, Brian Lloyd

Natural resources published reports

A five day field survey of degradation in the Southern River/Wungong Catchment revealed several areas of concern. Key concerns are:

- Erosion and Sedimentation

Various forms of water erosion were present that cumulatively, would probably have a significant effect on the water quality of the Canning (and Swan) River. Much of the water erosion results from the installation and maintenance of infrastructure and developments, e.g. roads, subdivisions, stormwater drains etc. Reviewing standard practices, raising of awareness of consequences of erosion and training in urban erosion and sediment control techniques is recommended. Wind erosion is also an issue on the sands …

Differentiation Of F18ab+ From F18ac+ Escherichia Coli By Single-Strand Conformational Polymorphism Analysis Of The Major Fimbrial Subunit Gene (Feda), Brad T. Bosworth, Evelyn A. Dean-Nystrom, Thomas A. Casey, Holly L. Neibergs

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Toxin-producing Escherichia coli expressing F18 fimbriae colonizes the small intestines of weaned pigs and causes diarrhea, edema disease, or both. The F18 family is composed of two antigenic variants, F18ab and F18ac. Because many strains do not express F18 fimbriae in vitro, identification and differentiation of these two variants are difficult. Single-strand conformational polymorphism (SSCP) analysis is a rapid method for identifying genetic mutations and polymorphisms. The F18 major fimbrial subunit genes (fedA) of 138 strains were amplified by PCR, and genetic differences were detected by SSCP analysis. The SSCP analysis of the fedA gene differentiated F18ab^{+ …}

Management Of Microbial Nitrate Production In Agricultural Soils, Wei Shi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrate (NO₃^-) is of central importance in the internal soil nitrogen (N) cycle. While animal wastes and nitrification inhibitors have been used in modern agriculture for decades, their effects on soil NO₃^- concentrations in relation to microbial NO₃^- production have not been well characterized. The objective of this research was to determine microbial NO₃^- production in relation to ammonium (NH₄⁺) availability and nitrifier population activity in agricultural soils receiving animal wastes or nitrification inhibitors.

Several laboratory and field studies assessed the impacts of variously treated dairy wastes and …

Regeneration Ecology Of Chrysopogon Aucheri And Cymbopogon Jwarancusa In Grasslands Of Upland Balochistan, Pakistan, Sarfraz Ahmad

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Field experiments were conducted to investigate the seed attributes, movements and fates of dispersal units, and seedling establishment of Chrysopogon aucheri and Cymbopogon jwarancusa in a representative grassland ecosystem in upland Balochistan, Pakistan.

Cymbopogon jwarancusa had more filled and viable caryopses than Chrysopogon aucheri. Seeds (spikelets) of both species had similar morphological features. Chrysopogon aucheri had one dispersal unit, a triplet spikelet. Cymbopogon jwarancusa had four types of dispersal units: a paired spikelet, a partial raceme, an entire raceme, and a partial inflorescence comprised of two racemes.

Paired spikelets and partial racemes of Cymbopogon jwarancusa had greater …

The Effects Of Rose Bengal Application On The Production Of Salicylic Acid In Nahg Tobacco Plants, Nicole Christine Ott

Honors Theses

Plants have the ability to develop resistance to a wide range of pathogens following exposure to a single bacterium, fungus, or virus. This resistance occurs in all tissues, not only those that were previously infected. This mechanisms is termed systemic acquired resistance (SAR). The phenolic compound salicylic acid (SA) has been linked to SAR in tobacco, arabidopsis, and cucumber plants. Oxidative stress also causes SA production, which leads to SAR. An engineered tobacco plant (nahG) that does not have the ability to accumulate SA has been used as a research tool in investigations concerning SA activity. Rose Bengal …

Development Of A Blocking Enzyme-Linked Immunosorbent Assay For Detection Of Serum Antibodies To O157 Antigen Of Escherichia Coli, William Laegreid, Mark Hoffman, James Keen, Robert Elder, Jimmy Kwang

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The O157 antigen of Escherichia coli shares structural elements with lipopolysaccharide (LPS) antigens of other bacterial species, notably Brucella abortus and Yersinia enterocolitica O9, a fact that confounds the interpretation of assays for anti-O157 antibodies. To address this problem, a blocking enzyme-linked immunosorbent assay (bELISA) was designed with E. coli O157:H7 LPS as the antigen and a monoclonal antibody specific for E. coli O157, designated 13B3, as the competing antibody. The bELISA had equivalent sensitivity to, and significantly higher specificity than, the indirect ELISA (iELISA), detecting anti-O157 antibodies in sera from cattle experimentally inoculated with O157:H7. Only 13% of sera …

An Economic Assessment Of The Myanmar Rice Sector: Current Developments And Prospects, Kenneth B. Young, Gail L. Cramer, Eric J. Wailes

AAES Research Reports and Research Bulletins

In this study, the Myanmar rice economy is described in the context of the current political situation and state of national economic development. The forces that are changing rice production and exports are identified; however, the rate of development involves a complex integration of government intervention and politics, as well as availability of resources. Probable scenarios for rice production and export are projected based on recent growth trends and expected infrastructure development. The Arkansas Global Rice Model is used to integrate the Myanmar rice sector with the global rice market in developing projections.
