Beef Cattle Production, Nutritional Quality, and Economics of Windrowed Forage vs. Baled Hay During Winter

Autor: Bret W. Hess, David W. Koch, A. D. Schleicher, Larry J. Held, J.W. Flake, V. Nayigihugu

Publikováno v: Agronomy Journal. 99:944-951

Production expenses associated with harvesting and feeding hay account for a large proportion of annual production costs for ruminant livestock systems. A 2-yr experiment compared windrow grazing, as a potential method to reduce winter cost, with fee

Production and Quality of Forage and Economics of Grazing a Hay Meadow in the Spring

Autor: Bret W. Hess, D.W. Koch, A. D. Schleicher, J.W. Flake, Larry J. Held, V. Nayigihugu

Publikováno v: The Professional Animal Scientist. 22:318-324

An experiment was conducted to determine the effects of spring grazing on forage DM production and nutritive value, as well as the economics of spring grazing a flood-irrigated hay meadow. Two vegetation types were present: predominantly ‘Garrison�

Agroeconomic Analyses of Drip Irrigation for Sugarbeet Production

Autor: Stephen D. Miller, Florence Cassel Sharmasarkar, Renduo Zhang, Larry J. Held, George F. Vance, Shankar Sharmasarkar

Publikováno v: Agronomy Journal. 93:517-523

Sugarbeet (Beta vulgaris L.) is a major cash crop in Wyoming where overuse of water and agrochemicals is a concern in furrowirrigated areas. Drip irrigation, an alternative technology, is not well developed for row crops within the state. Therefore,

Assessment of Microirrigation for Sugarbeet Production

Autor: George F. Vance, Stephen D. Miller, Shankar Sharmasarkar, Larry J. Held, Florence Cassel Sharmasarkar, Renduo Zhang

Publikováno v: Journal of Sustainable Agriculture. 17:17-32

Sugarbeet (SB) is a major value-crop in many furrow (Fu) irrigated areas of Wyoming where nitrate (NO3) contamination prevails. Microirrigation (M) may be an option for managing such pollution while sustaining SB production. With the goal of evaluati

Economics of Trap Cropping for Sugarbeet Nematode Control

Autor: Larry J. Held, Fred A. Gray, David Koch, James W. Jennings

Publikováno v: Journal of Sugarbeet Research. 37:45-56

The sugarbeet cyst nematode (SBCN), Heterodera schachtii Schmidt, is a major root parasite of sugarbeet (Beta vulgaris L.). It causes serious stand and yield reductions wherever sugarbeet is produced, particularly with fields located near refineries

Preplant and Postemergence Herbicide Systems in Wyoming Sugarbeet

Autor: Larry J. Held, S. D. Miller, K. J. Fornstrom

Publikováno v: Journal of Sugarbeet Research. 34:1-19

Field studies were conducted in 1994 at two locations in north west Wyoming and two locations in southeast Wyoming to ex amine sugarbeet (Beta vulgaris L.) weed management systems. Twelve systems were established incl uding three preplant op ti

An Economic Analysis of Reducing Nitrogen on Early Harvest Sugarbeets

Autor: Larry J. Held, Dale J. Menkhaus, Joseph G. Lauer, Paul A. Burgener

Publikováno v: Journal of Production Agriculture. 7:422-428

Both sugarbeet (Beta vulgaris L.) producers and sugar processors have interests in lengthening the harvest and processing season by harvesting a certain percentage of sugarbeet acreage earlier in the year. As a general practice, many growers have not

Potential Value of Soil Conservation Service Streamflow Outlook Based on Flexible Crop Combinations

Autor: James J. Jacobs, Larry J. Held, Eric A. Wenberg

Publikováno v: Journal of Production Agriculture. 6:126-132

The potential value of Soil Conservation Service (SCS) water supply outlook information was examined with a representative case farm situation in which crop enterprise combinations and irrigation practices could be adjusted in response to expected wa

Management Options for Sugarbeet Stand Establishment

Autor: P. A. Burgener, Larry J. Held, S. D. Miller, K. J. Fornstrom

Publikováno v: Journal of Sugarbeet Research. 29:9-21

A large part of a sugar beet (Beta vulgaris L.) grower's cost of production is the cost of obtaining an adequate stand of weed-free sugarbeet. Field experiments were conducted at four locations in Wyoming during 1990 to demonstrate the economic benef
