Dahlia Cut Flower Production In Utah, Melanie Stock, Amanda Pratt, Claudia Nischwitz, Eli Oliver, Katie Wagner, Nick Volesky

All Current Publications

Dahlias are tuberous, herbaceous plants that are frost sensitive and therefore grown as a warm-season annual for cut flower production in Utah. Dahlias bloom in summer to fall, with peak production in late summer to early fall, and the season ending with first frost. Plants benefit from pinching to encourage branching and horizontal trellising or staking to promote straight stems and avoid toppling. High tunnels or extended low tunnels with shade, as well as optimum nitrogen and irrigation rates, improve production. As showstoppers in arrangements, dahlia cut flowers are highly desired on local markets and profitable to produce, particularly those …

Snapdragon Cut Flower Production In Utah, Maegen Lewis, Melanie Stock, Tiffany Maughan, Brent Black, Dan Drost

All Current Publications

This fact sheet describes snapdragon cut flower production in Utah. Snapdragons can bloom spring through fall, with the highest quality stems produced during cool temperatures. Cultivars are grouped based on their blooming response to light and temperature. High-quality stem production can last up to 21 weeks by using multiple groups, staggered planting dates in a high tunnel and field, pinching, and pruning techniques.

Peony Cut Flower Production Budget, One Field, Northern Utah, 2020, Maegen Lewis, Melanie Stock, Ruby Ward, Brent Black, Dan Drost

All Current Publications

This enterprise budget contains costs (preplant and site preparation, establishment and maintenance, and harvest and processing) and returns for the production and sale of peony cut flowers that were grown in a field (14 feet by 42 feet, the size of one high tunnel for comparison). Peonies are a perennial crop that require at least three years for establishment and produce in years 4-20. The costs are representative, but should be adjusted where necessary for individual situations. The net income resulting from stems sold at a price of $5.00 per high-quality stem (100% sold) and $2.00 per low quality stem …

Animal, Dairy, and Veterinary Science Faculty Publications

In 2008, a consortium led by the Agricultural Research Service (ARS) and the National Institute for Food and Agriculture (NIFA) published the “Blueprint for USDA Efforts in Agricultural Animal Genomics 2008–2017,” which served as a guiding document for research and funding in animal genomics. In the decade that followed, many of the goals set forth in the blueprint were accomplished. However, several other goals require further research. In addition, new topics not covered in the original blueprint, which are the result of emerging technologies, require exploration. To develop a new, updated blueprint, ARS and NIFA, along with scientists in the …

Approaches For Studying Fish Production: Do River And Lake Researchers Have Different Perspectives? – Extended Abstract, Wayne A. Wurtsbaugh, Nicholas A. Heredia, Brian G. Laub, Christy S. Meredith, Harrison E. Mohn, Sarah E. Null, David A. Pluth, Brett B. Roper, W. Carl Saunders, David King Stevens, Richard H. Walker, Kit Wheeler

Biased perspectives of fisheries researchers may hinder scientific progress and effective management if limiting factors controlling productivity go unrecognized. We investigated whether river and lake researchers used different approaches when studying salmonid production and whether any differences were ecologically supported. We assessed 564 peer‐reviewed papers published between 1966 and 2012 that studied salmonid production or surrogate variables (e.g., abundance, growth, biomass, population) and classified them into five major predictor variable categories: physical habitat, fertility (i.e., nutrients, bottom‐up), biotic, temperature, and pollution. The review demonstrated that river researchers primarily analyzed physical habitat (65% of studies) and lake researchers primarily analyzed fertility …

Methane Production By Mixed Ruminal Cultures Incubated In Dual-Flow Fermentors, Jong-Su Eun, V. Fellner, M. L. Gumpertz

Animal, Dairy, and Veterinary Science Faculty Publications

This study evaluated the effects of dilution rate and forage-to-concentrate ratio on gas production by rumen microbes. Continuous cultures were used to monitor methane production at three liquid dilution rates (3.2, 6.3, or 12.5%/h) and three forage-to-concentrate ratios (70:30, 50:50, or 30:70). Filtered ruminal contents were allowed 6 d of adaptation to diets followed by 7 d of data collection. Forage consisted of pelleted alfalfa and the concentrate mix included ground corn, soybean meal, and a mineral and vitamin premix. The experiment was replicated in a split-plot design. Total volatile fatty acid production averaged 58.0 mmol/d and was not affected …

Adding Nutrients To Enhance The Growth Of Endangered Sockeye Salmon: Trophic Transfer In An Oligotrophic Lake, Phaedra E. Budy, Chris Luecke, Wayne A. Wurtsbaugh

Watershed Sciences Faculty Publications

Snake River sockeye salmon Oncorhynchus nerka, listed under U.S. law as endangered in 1991 in response to a decline in anadromous adult numbers, spend their first 1–2 years in Redfish Lake, Idaho, before migrating to the sea. To determine how nutrient enhancement might influence phytoplankton, zooplankton, and fish production, we performed fertilization experiments in large enclosures in this oligotrophic lake using juvenile kokanee (lacustrine O. nerka) as analogues for endangered sockeye salmon. Fertilization of the metalimnion substantially increased chlorophyll a (150%), phytoplankton biovolume (75%), primary productivity (250%), and zooplankton biomass (200%), and moderately increased fish growth (12%) over our control …

Simulated Growth And Production Of Endangered Snake River Sockeye Salmon: Assessing Management Strategies For The Nursery Lakes, Chris Luecke, Wayne A. Wurtsbaugh, Phaedra E. Budy, H. P. Gross

Watershed Sciences Faculty Publications

We examined the potential of employing a series of lake management strategies to enhance production of endangered Snake River sockeye salmon (Oncorhynchus nerka) in its historical nursery lakes in central Idaho. We used a combination of limnological sampling, experimentation, and simulation modeling to assess effects of lake fertilization and kokanee reduction on growth and survival of juvenile sockeye salmon. Juvenile sockeye salmon from a broodstock of this endangered species are being introduced into the lakes from 1995 to 1998. Results of our analyses indicated that several lakes were suitable for receiving broodstock progeny. Field experimentation and simulation modeling indicated that …

Sheep Production In 11 Western States, United States Department Of Agriculture, Economic Research Service

Agriculture

Net cash returns of U.S. sheep producers were positive for the past 18 years, yet the industry in 1986 experienced the largest declines in number of sheep farms and in sheep population since 1942. Per capita consumption of lamb and mutton has trended downward since 1962, remaining below 1.5 pounds for the past 13 years. The 1986 USDA Farm Costs and Returns Survey indicates that the major sheep production practices of shed and range lambing have not changed significantly since 1980, and losses from disease and predators are high. Sheep production requires more hired labor and operator time than any …

Asexual Vs. Sexual Propagation Of Quaking Aspen, Robert B. Campbell Jr.

Aspen Bibliography

ABSTRACT: Quaking aspen (Populus tremuloides Michx.)

regenerates almost exclusively by root suckers in the

western United States, even though female clones

produce abundant viable seed. During the past decade,

interest in propagating aspen for use as an

ornamental and for revegetation of forest land has

increased. To satisfy these diverse needs for aspen

planting stock, nurserymen have a choice between

sexual and asexual propagation. Criteria for clone

selection, suggestions for root and seed collection

and storage, propagation techniques, and the

advantages of both sexual and asexual propagation are

discussed.

Simulation Of The Daily Growth Of An Aspen Population From The Measured Co2-Exchange Rates Of The Components, G.C. Bate, D.T. Canvin

Aspen Bibliography

The daily total CO₂-exchange of an aspen population (32 trees) was measured using a growth chamber gas analysis system which had been shown to measure accurately the actual carbon gain of the population. The CO₂-exchange rates of the components (e.g. roots, stems, leaves) were measured in the light and dark and these rates were used to calculate the total CO₂-exchange of the population using a computer model. The carbon gain during the photoperiod was underestimated by 25% in the simulation while the carbon loss during the nyctoperiod was overestimated 100% by the simulation.

Bulletin No. 386 - Production Of Lettuce Seed As Affected By Soil Moisture And Fertility, Leslie R. Hawthorn, Leonard H. Polland

UAES Bulletins

Much of the lettuce seed produced in the United States is grown under irrigation in various western states. Few studies have been made to determine the extent to which yields of seed are influenced by soil moisture and other cultural conditions. Crops have been irrigated mostly on the basis of local practices and the general experience of the grower. Recent studies in Utah (Hawthorn 1951) showed rather conclusively that carrot and onion seed crops grown side by side under the same climatic conditions differ widely in their response to soil moisture. High seed yields were obtained from carrots grown under …

Bulletin No. 355 - An Economic Study Of The Production Of Canning Tomatoes In Utah, 1948 And 1949, Earnest M. Morrison, George T. Blanch

UAES Bulletins

Production of canning tomatoes is an important enterprise on many farms in Utah. In 1949 this crop brought about $1,772,000 and in 1951, nearly $2,750,000 to the farmers of the state (appendix table 1). Nearly all the canning tomatoes of the state are produced in the counties at the west of the Wasatch Mountains. In order of importance, these are: Davis, Weber, Utah, Box Elder, and Salt Lake (appendix table 2). Since tomatoes are processed relatively close to where they are grown, the income to farmers is not a complete measure of the importance of the tomato enterprise to this …

Bulletin No. 354 - Marketing Of Chickens From Producer To First Handler Washington, Oregon, And Utah (1948-1949), Roice H. Anderson

UAES Bulletins

In 1949 the receipts from eggs and chickens amounted to 8.6, 6.0, and 13.2 percent of the total cash receipts from farm marketings in Washington, Oregon, and Utah, respectively. About three fourths of these receipts were from sale of eggs and one fourth from the sale of chickens. Receipts from chicken sales, while less important than from eggs, amounted to about 21.5 million dollars in 1949 in the three states. As would be expected, considering the importance of egg production in the three states, many of the chickens sold are cull layers and other chickens produced incidental to the egg …

Bulletin No. 329 - Cost And Efficiency Of Producing Sugar Beets In Utah, 1945, Ernest M. Morrison

UAES Bulletins

Early in the history of Utah the pioneers became interested in sugar-beet production. In 1852 John Taylor, Elias Morris and others, under the direction of Brigham Young, obtained machinery from France for refining beet sugar, transported it across the Atlantic Ocean by boat, up the Mississippi River to Fort Leavenworth, and thence across the plains to Utah by ox teams. The factory was established in what is now known as Sugar House in the southeastern part of Salt Lake City. These initial efforts proved to be unsuccessful primarily because the "open kettle" method employed was never satisfactory.

Not until 1891 …

Bulletin No. 284 - Lygus Bugs In Relation To Alfalfa Seed Production, C. J. Sorenson

UAES Bulletins

This investigation, which continued during the two succeeding years, had four primary purposes: (1) to determine the distribution of these plant bugs and the intensity of their infestation in the alfalfa-seed districts of the state; (2) to ascertain whether these bugs constitute an important factor, either causing or contributing to, the excessive flower-drop annually occurring in alfalfa-seed fields, or if they are otherwise responsible for decreased yields of alfalfa seed; (3) to study the general biology of these insects with particular reference to their life histories in alfalfa as the host plant; and (4) to investigate possible practical methods for …

Bulletin No. 263 - Relative Produciton Of Feed Grain From Spring-Grown Cereals In Utah, R. W. Woodward, D. C. Tingey

UAES Bulletins

Nearly one-third of the cropped acreage of Utah is devoted to cereals. Except for wheat, most of these crops are fed locally. In addition to this, an average of over a million bushels of corn, barley, and oats is shipped into the state each year to be used in various livestock and poultry industries.

The purpose of this publication is to show the comparative amount of feed produced by the different crops--wheat, oats, barley, and corn--under similar conditions as determined for the specified four years by acre-yields obtained in various agricultural regions of the state. One should bear clearly in …

Circular No. 98 - Insects In Relation To Alfalfa-Seed Production, Charles J. Sorenson

Various insect pests have been suspected of causing the unsatisfactory alfalfa-seed yields that have been obtained in Utah during recent years. No specific information was at hand giving the amount and nature of the damage which these insects were suspected of doing.

Bulletin No. 229 - Production Study Of 160 Dairy Herds: Wellsville, Utah, 1929, George Q. Bateman

UAES Bulletins

The condensed milk plant located at Wellsville, Utah, could use more milk to an advantage. The dairymen of the section were anxious to supply this demand. The dairymen and manufacturers cooperatively planned a survey to determine by what means this demand could be brought about: Should the dairymen increase the size of their herds? If not, what could be done to increase dairy production?

Bulletin No. 226 - Alfalfa-Seed Production, J. W. Carlson, George Stewart

UAES Bulletins

Utah's alfalfa-seed crop is of far-reaching importance. Since 1919, the growing of this crop has been a major industry in western Millard County and in that part of the Uintah Basin situated in Utah. These places are two of the relatively few large areas in the United States peculiarly adapted by climate for the successful growing of alfalfa-seed. As a cash crop, alfalfa-seed has a high commercial value. It is also the basis of the state's alfalfa hay crop, which in turn constitutes the foundation of Utah's livestock industry. Because of its wide dissemination, Utah's alfalfa-seed crop influences the feed …
