Crop/Livestock Integration Effects On Soil Quality, Crop Production, And Soil Nitrogen Dynamics, Ellen B. Mallory

Electronic Theses and Dissertations

Regional integration of potato and dairy farms has developed in Maine through arrangements where manure, feed, and sometimes land, are exchanged between neighboring farms. The effects of integration on soil quality, crop production, nitrogen (N) cycling, and N loss were investigated in field and laboratory studies of contrasting amended (manure, compost, green manure, and supplemental fertilizer) and nonamended (fertilizer only) soil management systems within 2-year potato (Solanum tuberosum L.) rotations in the Maine Potato Cropping Systems Project (MPEP). Additionally, soil quality of 48 integrated and nonintegrated Maine potato and dairy farm fields was assessed. The MPEP’s amended soil system enhanced …

Assessment Of Genetic Diversity In The Usda And Cip-Fao International Nursery Collections Of Quinoa (Chenopodium Quinoa Willd.) Using Microsatellite Markers, S. A. Christensen, D. B. Pratt, C. Pratt, P. T. Nelson, M. R. Stevens, Eric N. Jellen, Craig E. Coleman, Daniel J. Fairbanks, A. Bonifacio, Michael J. Maughan

Faculty Publications

Quinoa (Chenopodium quinoa Willd.) is a staple food crop for millions of impoverished rural inhabitants of Andean South America where it has been cultivated for millennia. Interest in quinoa, due largely to its superior nutritional characteristics, is fuelling a growing export market and has led to an increased focus on genetic research and the development of quinoa breeding programmes throughout South America. The success of these breeding programmes will rely heavily on the development of core germplasm collections and germplasm conservation. We report the development of a set of fluorescence-tagged microsatellite molecular markers that can be used to characterize genetic …

Identification And Control Of Pest Slugs And Snails For Broadacre Crops In Western Australia, Svetlana Micic, Ken Henry, Paul Horne

Bulletins 4000 -

The numbers of slugs and snails have increased in broadacre cropping in Western Australia with the use of minimum tillage and stubble-retention practices. The organic content of paddocks increases under such systems, providing an increased food source especially to young slugs and snails. Soil moisture content is greater over summer leading to higher survival levels of slugs and snails.

Slug and snail pests in Australia have come from other countries, mainly the Mediterranean region. They damage plant seeds (mainly legumes), recently germinated seeds, seedlings and leaves and can be a contaminant of grain at harvest.

Spotted Cotton Oligonucleotide Microarrays For Gene Expression Analysis, Joshua Udall, Lex E. Flagel, Foo Chung, Andrew W. Woodward, Ran Hovav, Ryan A. Rapp, Jordan M. Swanson, Jinsuk J. Lee, Alan R. Gingle, Dan Nettleton, Christopher D. Town, Z. Jeffrey Chen, Jonathan F. Wendel

Faculty Publications

Microarrays offer a powerful tool for diverse applications plant biology and crop improvement. Recently, two comprehensive assemblies of cotton ESTs were constructed based on three Gossypium species. Using these assemblies as templates, we describe the design and creation and of a publicly available oligonucleotide array for cotton, useful for all four of the cultivated species. Results: Synthetic oligonucleotide probes were generated from exemplar sequences of a global assembly of 211,397 cotton ESTs derived from <50 different cDNA libraries representing many different tissue types and tissue treatments. A total of 22,787 oligonucleotide probes are included on the arrays, optimized to target the diversity of the transcriptome and previously studied cotton genes, transcription factors, and genes with homology to Arabidopsis. A small portion of the oligonucleotides target unidentified protein coding sequences, thereby providing an element of gene discovery. Because many oligonucleotides were based on ESTs from fiber-specific cDNA libraries, the microarray has direct application for analysis of the fiber transcriptome. To illustrate the utility of the microarray, we hybridized labeled bud and leaf cDNAs from G. hirsutum and demonstrate technical consistency of results. Conclusion: The cotton oligonucleotide microarray provides a reproducible platform for transcription profiling in cotton, and is made publicly available through http://cottonevolution.info.

Impact Of The Agricultural Sector On The Arkansas Economy In 2003, Jennie Popp, Nathan Kemper, Wayne Miller

Research Reports and Research Bulletins

Agriculture and associated agricultural activities are major contributors to the Arkansas economy. Agriculture is defined as the sum of agricultural production and processing activities, unless otherwise specified, and includes crop and animal production and processing, agricultural support industries, forestry and forest products, and textile goods. Agriculture contributes to the economy through direct agricultural production and value-added processing, and also leads to economic activity in other parts of the economy.

Root Lesion And Burrowing Nematodes In Western Australian Cropping Systems, Vivien Vanstone

Bulletins 4000 -

Nematodes are common soil pests that feed on the roots of a wide range of crop plants in all agricultural areas of Western Australia, irrespective of soil type and rainfall. Nematodes multiply on susceptible hosts. Consequently, as nematode populations increase, crop production is limited. Cereal yield losses due to nematodes in Western Australia are in the order of 5 to 15 per cent per annum, but individual losses as high as 40 per cent have been recorded.

Forage Quality: What Is It? What Can We Do About It? And, Will It Pay?, Garry D. Lacefield

Forage Symposium at the Kentucky Cattlemen’s Convention

Profitable livestock production almost always requires a forage program that will supply large quantities of adequate quality, homegrown feed. A major percentage of the feed units for beef (83%) and dairy cattle (61%) come from forages. In addition, forages supply an estimated 91%, 72%, 15% and 99% of the nutrients consumed by sheep and goats, horses, swine, and wildlife, respectively.

Can I Afford To Seed Novel-Endophyte Tall Fescue?, Kenneth H. Burdine

Forage Symposium at the Kentucky Cattlemen’s Convention

Tall fescue is the predominant forage grass of Kentucky. It is an easily established, relatively persistent bunchgrass that has reasonable drought tolerance and does well in clay or loam soils. However, the endophyte fungus found in the grass was linked to poor animal performance in the late 1970’s (Ball, Hoveland, and Lacefield). It has been estimated that 85% of Kentucky’s fescue pastures are endophyte infected, making it a serious problem for Kentucky cattle producers (Lacefield, Henning, and Philips). Producers interested in establishing or replacing tall fescue stands have several options available to them.

How I Produce, Manage And Market Forages, Bill Payne

Forage Symposium at the Kentucky Cattlemen’s Convention

I would like to amend the title to: “How I Produce, Manage and Market Forages, Profitably.” My experience has led me to believe that keeping things simple has allowed me to focus better and that has led to profitability. This has led me to make every effort to reduce my reliance on machinery and to allow the cows to do the work. I focus on maximizing forage utilization and minimizing the number of days of feeding stored feeds.

Where To Find Forage Information On The Web, Tom Keene

Forage Symposium at the Kentucky Cattlemen’s Convention

The Internet can take you almost anywhere you want to go these days. You can gather information, shop, take classes, play games, etc. So, it is logical to assume that you can find lots of information about forages on the Internet.

Incorporating Sheep Into Dryland Grain Production Systems Iii. Impact On Changes In Soil Bulk Density And Soil Nutrient Profiles, P. G. Hatfield, H. B. Goosey, T. M. Spezzano, Sue L. Blodgett, Andrew W. Lenssen, R. W. Kott, C. B. Marlow

Andrew W. Lenssen

Changes in soil bulk density and soil nutrient profiles are a major concern of dryland grain producers considering grazing sheep on cereal stubble fields. Our objective was to compare burned, grazed, tilled, trampled and clipped wheat stubble fields on changes in soil bulk density and soil nutrient profiles. Treatments were evaluated in a series of three experiments using a randomized complete block design and four replications at each site. Contrast statements were used to make pre-planned comparisons among treatments. For Experiment 1, treatments were fall tilled, fall grazed, spring grazed, fall and spring combined (Fall/Spr) grazed, and an untreated control. …

Andrew W. Lenssen

Weed control in fallow management to conserve soil moisture and nutrients is the largest variable cost to dryland grain production. Our objective was to compare burning, grazing, tilling, trampling and clipping wheat stubble fields on changes in total above ground biomass and weed density. Treatments were evaluated in three experiments using a randomized complete block design for each experiment with four replications at each site. Contrasts statements were used to make pre-planned comparisons. For experiment 1, treatments were fall tilled, fall grazed, spring grazed, fall and spring combined (Fall/Spr) grazed, and an untreated control. For grazing treatments, five mature ewes …

Genetic Diversity And Low Reproductive Success In Isolated Populations Of Utah Juniper (Juniperus Osteosperma, Cupressaceae), Loreen Allphin, Val J. Anderson, Amy F. Hunt

Faculty Publications

Utah juniper (Juniperus osteosperma) has greatly expanded its historical range in the western United States. Management plans for the species have focused on curtailing its encroachment into sagebrush and grassland communities. These plans often include burning or other methods of elimination. These methods may result in subdivision or fragmentation of existing juniper stands. We initiated a study at Dugway Proving Ground, a U.S. Army facility, to examine the effects of fragmentation on the reproductive success of Utah juniper in isolated populations. We used enzyme electrophoresis to quantify genetic variability in isolated populations. We also determined population reproductive success by examining …
