Small Grains And Field Peas: 2007 Variety Recommendations (2006 Crop Performance Results), Cooperative Extension Service, South Dakota State University

SDSU Extension Circulars

Variety selection is a fundamental element in a sound crop production program. This report contains variety recommendations, descriptions, and yield data for the spring-seeded small grains – hard red spring wheat, oat, and barley, along with the fall-seeded small grain –hard red winter wheat. Key factors in variety selection include yield, yield stability, maturity, straw strength, height, test weight, quality, and disease resistance. Yield is an important factor; however, a variety with good disease resistance, straw strength, and high grain quality may be more profitable in some cases than the highest yielding variety. Disease resistance information is based on reactions …

Microarray Analysis Of Late-Season Velvetleaf (Abutilon Theophrasti) Effect On Corn, David P. Horvath, Robert Gulden, Sharon A. Clay Dec 2006

Microarray Analysis Of Late-Season Velvetleaf (Abutilon Theophrasti) Effect On Corn, David P. Horvath, Robert Gulden, Sharon A. Clay

Agronomy, Horticulture and Plant Science Faculty Publications

Microarray analysis was used to identify changes in gene expression in corn leaves collected from plants at the V11–14 growth stage that resulted from competition with velvetleaf. The plants were grown in field plots under adequate N (addition of 220 kg N ha1) and irrigation to minimize N and water stress. Consequently, only differences resulting from competition for micronutrients, light, and perhaps allelopathic stress were anticipated. Genes involved in carbon and nitrogen utilization, photosynthesis, growth and development, oxidative stress, signal transduction, responses to auxin and ethylene, and zinc transport were repressed in corn growing in competition with velvetleaf. …

Using The Balanced Scorecard For Ranch Planning And Management:Setting Strategy And Measuring Performance, Barry H. Dunn, Roger N. Gates, Jack Davis, Agustin Arzeno

SDSU Extension Circulars

The key to business success—whether operating a ranch or a Fortune 500 company—lies in management and planning. It’s the ability to have foresight, to carefully evaluate and choose appropriate new concepts and technologies, and to implement a well thought- out plan that complements all aspects of the business. The highly-respected former CEO and chairman of General Electric Jack Welch put it this way: Good business leaders create a vision, articulate the vision, passionately own the vision, and relentlessly drive it to completion. How does that description apply to you? Are you a visionary business leader for your ranch enterprise? Or …


Potential Use Of The Conservation Security Program To Encourage Diverse Crop Rotations In Eastern South Dakota, Thomas Dobbs, Nicholas J. Streff Jul 2006

Potential Use Of The Conservation Security Program To Encourage Diverse Crop Rotations In Eastern South Dakota, Thomas Dobbs, Nicholas J. Streff

Economics Research Reports

A central concern in many discussions of ecological sustainability in agricultural regions of the U.S. Midwest and Great Plains is that of crop system diversity. Many factors have contributed to the loss of crop system diversity over that last half-century (Dumke and Dobbs), one of which is public policy. The U.S. Farm Security and Rural Investment Act of 2002 ('2002 Farm Bill') provided for a new agri-environmental program that could have potential to help restore some of the crop system diversity that has been lost. The Conservation Security Program (CSP) is that program. This report, drawn from a Master of …

North Central Water Quality Survey¹, Lanette Butler, Cody L. Wright Jan 2006

North Central Water Quality Survey¹, Lanette Butler, Cody L. Wright

South Dakota Beef Report, 2006

This survey was conducted to determine the water quality in north central South Dakota. Twenty-one water sources from 16 different livestock operations were surveyed for this project. The water sources included five runoff-fed dugouts, 6 spring-fed dugouts, 4 deep wells (> 1000 ft), 3 medium-depth wells (100 to 500 ft) and 3 shallow wells (< 100 ft). Each water sample was initially tested with a hand-held Hanna Dist WP4 electroconductivity (EC) meter and the readings were recorded. Samples were then shipped to Servi-Tech Laboratories in Hastings, NE, where they were tested for EC, total dissolved solids (TDS), hardness, pH, calcium (Ca), chloride (Cl), magnesium (Mg), potassium (K), sulfate (SO4), sulfate-sulfur (SO4-S), and sodium (Na). Water quality indicators and mineral concentrations were not different over time when analyzed across all water sources or within each water source independently. Water from runoff-fed dugouts was lower (P < 0.05) in pH than water from spring-fed dugouts or wells. Well water contained greater (P < 0.05) concentrations of Cl than water from either runoff-fed or spring-fed dugouts. Potassium concentrations were greater (P < 0.05) in water from runoff-fed dugouts than in water from spring-fed dugouts or well water. Estimation of water quality without testing is highly inaccurate and variable. Livestock producers should obtain water samples for determination of water quality and adjust management to account for poor-quality water sources.

Effects Of Standing Estrus And Concentrations Of Estradiol On Uterine Ph¹, Josh R. Nelson, Bandi L. Perry, George A. Perry

South Dakota Beef Report, 2006

Research has demonstrated that cows that are in estrus within 24 h of fixed-time AI had elevated concentrations of estradiol and greater pregnancy rates compared to cows that are not in estrus. Our objective was to determine if estradiol and/or estrus had an effect on uterine pH during a fixed-time AI protocol. Non-lactating beef cows (n = 20) were treated with the CO-Synch protocol (100μg GnRH on d -9; 25 mg PG on d -2; and 100μg GnRH on d 0). Half (n = 10) the cows received an injection of estradiol cypionate (ECP; 1mg) 12 h following PG. Cows …

Cost Of Gain Comparison Between Cattle Finished At Opportunities Farm In South Dakota And Cattle Finished In Kansas, Erik Loe, Robbi Pritchard, Matt Loewe Jan 2006

Cost Of Gain Comparison Between Cattle Finished At Opportunities Farm In South Dakota And Cattle Finished In Kansas, Erik Loe, Robbi Pritchard, Matt Loewe

South Dakota Beef Report, 2006

Cost of gain is an important factor in determining the profit or loss of feeder cattle. For comparison of cost of gain between cattle finished in Southeast South Dakota and cattle finished in Southwest Kansas closeouts of cattle fed at the Opportunities Farm near Lennox, SD were compared with information published by Kansas State University in the monthly Focus on Feedlots. Cattle feeders in the Midwest, including South Dakota, are competitive with cattle feeders in other regions of the United States due to this regions lower ration costs and cost of gain.

Calibrating A Food Thermometer, Lorna Saboe-Wounded Head

SDSU Extension Extra Archives

Using a properly calibrated thermometer is essential to ensure that foods are cooked to the correct temperature, chilled rapidly, or held at proper temperatures after cooking. A thermometer should be calibrated before the first use, after an extreme temperature change (such as going from hot food to frozen food), if the thermometer is dropped, or if it is used many times. Clean thermometers after each use by washing in hot soapy water, rinsing, sanitizing, and air drying.
