Emerging Enemy Of Veggies Unmasked, Carolee T. Bull, Marcia Wood

Agricultural Research Magazine

Chic, trendy veggies like arugula and baby broccoli, and familiar stand-bys like Brussels sprouts and cauliflower, are vulnerable to attack by a once-puzzling pathogen. Agricultural Research Service plant pathologist Carolee T. Bull and colleagues have, in laboratory, greenhouse, and field research, detected, identified, renamed, and classified the plant-killing microbe that’s now officially known as Pseudomonas cannabina pv. alisalensis. “Pv.” stands for “pathovar” and indicates that the microbe is a specific pathogenic form, or strain, of a species.

Their work has sorted out some of the taxonomic confusion surrounding classification of the large, complex group of harmful bacteria in …

New Club Wheat Holding Its Own Against Fungal Disease, Kim Garland-Campbell, Jan Suszkiw

Agricultural Research Magazine

Pacific Northwest wheat growers now have added insurance against outbreaks of yield-robbing fungi, thanks to Cara, a soft, white, winter club wheat cultivar developed by the Agricultural Research Service that boasts high levels of disease resistance and outstanding flour quality.

Washington State accounts for 77 percent, or 230,000 acres, of the entire U.S. club wheat crop, with the remainder produced in Oregon and Idaho. Much of the acreage in Washington and Oregon is planted with three cultivars: Bruehl, Cara, and Chukar. Spring-sown club wheat cultivars JD and Eden are grown on another 11,000 acres. Although several other winter club wheats …

A Well Designed Goat Grazing Plan Can Reduce Noxious Weeds, Sterling Banks

All Current Publications

Goat grazing can be an effective tool in reducing noxious weeds, if the right grazing plan is designed and implemented. Areas where herbicides are not an option or limited, goat grazing can reduce noxious weeds by reducing seed production and plant growth.

Annual Costs To Establish And Maintain Birdsfoot Trefoil Pastures In Northern Utah, 2012, Kynda Curtis, Trevor Knudsen, Jennifer Macadam

All Current Publications

This publication is meant to reflect birdsfoot trefoil establishment and maintenance costs on a small-scale cattle grazing area (5 to 10 acres). Birdsfoot trefoil is a perennial legume, and under proper irrigation and management, stands in northern Utah can persist for up to 8 years after seeding. Establishment costs are amortized annually based on a 6 year stand life.

Virtual Water, Marianna Khachaturyan, E. Wesley F. Peterson

Cornhusker Economics

Life on earth depends on water. Unfortunately, water resources are not evenly distributed. There are countries with abundant water supplies, such as Brazil or Canada, and countries that lack water resources, such as Egypt or Jordan. Because water is critical for the production of food and other goods, as well as for human consumption, recreation and ecosystem support, competition among the various users for available supplies is often intense. The problem is compounded by the fact that water markets often work imperfectly or are lacking altogether.

What can countries with limited water resources do? In rare cases, it may be …

The Role Of Speculators In Recent Price Volatility In Wheat Futures Markets, Jacob Delane Holloway

Student Theses and Dissertations

Investors in the agricultural futures markets have been blamed for the recent price spikes. Consequently, policies have been proposed to curb speculation in these markets. This study evaluates "excessive" speculation or the lack thereof in the US wheat markets using hedging ratios, speculative ratios, Working's speculative `T' index and Granger causality tests to examine the investment activities of commodity index traders. The study results show that there is no "excess" speculation in the US wheat markets over the 2006-2011 periods. Indeed, the speculation levels found in this study are not significantly different from historical results reported in other studies and …

Nitrogen Dynamics Of Switchgrass, Eastern Gamagrass And High Biomass Sorghum From Different Sources Of Chemical And Organic Nitrogen Fertilizers, Lucia Margarita Acosta Gamboa

Student Theses and Dissertations

Use of biomass to produce energy is a renewable source. A field experiment was established during 2009 in Northeast Arkansas to evaluate eastern gamagrass, switchgrass and biomass sorghum response to nitrogen fertilization on nitrogen dynamics and dry biomass yield. Nitrogen fertilizers included municipal biosolids, poultry litter, urea and a control. Throughout 2010 and 2011, switchgrass yielded greater biomass compared to gamagrass. Nitrogen fertilization increased yield compared to the control. In 2010, nitrogen use efficiency was greater for switchgrass compared to gamagrass. During 2011 NUE was lesser for biomass sorghum than for gamagrass. Switchgrass yielded greater biomass than gamagrass and biomass …

Advantages Of Understanding The Lady Beetle Diet, Jonathan Lundgren

Agricultural Research Magazine

Understanding the feeding behavior of lady beetles will help agronomists develop cropping systems that best use these important beneficial insects as biological controls of insect pests, such as aphids and Colorado potato beetles.

Agricultural Research Service entomologist Jonathan Lundgren at the North Central Agricultural Research Laboratory in Brookings, South Dakota, and former ARS entomologist Michael Seagraves were part of a team of ARS and university scientists that examined how lady beetle diets alter their feeding patterns and physiology.

Appreciated for their ability to eat insect pests, lady beetles also consume nectar, pollen, and other plant tissue. Indeed, most beneficial predators …

Corn Cobs On Deck For Cellulosic Feedstock, Brian J. Wienhold, Ann Perry

Agricultural Research Magazine

When energy officials proposed using crop residues to produce cellulosic ethanol, concerned soil scientists took to the fields to learn more about how these residues protect soil from erosion and enhance soil quality. Agricultural Research Service soil scientist Brian Wienhold focused on a single component of residue— the corncob.

“We didn’t have data on how postharvest cob residues might protect soil quality,” says Wienhold, who works in the ARS Agroecosystem Management Research Unit in Lincoln, Nebraska. “But corncobs make up 20 percent of residue by weight, which means that the average U.S. production of corn could provide 40 to 50 …
