Benefits And Costs Of Saltland Pastures On Moderately Salt-Affected Land, Justin Hardy, Arjen Ryder

Resource management technical reports

Summary The analyses in this report show that there could be significant economic benefits to the state, regions and affected farm businesses from establishing improved saltland pasture systems on moderately salt-affected land. The report clearly describes the methods of analysis and the assumptions about prices, productivity and adoption levels. The price of grain has been used as the key factor controlling the economic value of the saltland grazing because grain is the alternative supplementary feed for sheep over the summer and autumn period. Therefore, where yield is below break-even on moderately salt-affected land, it has a higher economic value and …

Photosynthetic Characteristics Of Veratrum Californicum In Varied Greenhouse Environments, Jeffrey Adelberg, Youping Sun, Sarah White, David Mann

Publications

Corn lily or California false hellebore (Veratrum californicum Durand), a perennial species native to the western United States, produces several alkaloid compounds. A derivative of these alkaloid compounds, primarily veratramine and cyclopamine, shows promise as a therapeutic agent for treatment of a variety of tumor types. Here we report the first study of corn lily cultivated in greenhouse. Growth response of corn lily was examined under two light levels (ambient and supplemental), two fertilization types (20 N-4.4 P- 16.6 K Peat-lite special and 15N-2.2P-12.5K CalMag special) at 100-mg·L-1 total nitrogen, and three irrigation cycles [sub-irrigation every day (wet), every third …

Measurement Of The Effect Of Policy Changes On Volatility In Dairy Markets1, Eoin Kelly, Declan O'Connor, Michael Keane

Irish Business Journal

Volatility in dairy commodity markets has become a major concern for many in the dairy supply chain and is likely to remain so in the future. Changes to the Common Agricultural Policy (CAP) over the past decade have more closely aligned EU and World prices and their associated volatilities. The aim of this paper is to measure volatility at farm level in Ireland over time, identify possible reasons for the increased volatility and identify ways of reducing volatility. Statistical measures such as coefficient of variation (CV) and annualised standard deviation are used to provide measures of past volatility and its …

Crop-Friendly Bacteria Tapped To Battle Fungal Marauders, Patricia Okubara, Jan Suszkiw

Agricultural Research Magazine

Soil-dwelling bacteria that depend on wheat and barley roots for their “room and board” could soon make good on their debt. Researchers are investigating the microbes’ potential to biologically control root-rot fungi that cause crop yield losses of 10-30 percent annually in the U.S. Pacific Northwest and other parts of the world.

The bacteria are members of the genus Pseudomonas and include 11 strains that stymie the growth of Pythium and Rhizoctonia fungi, which are responsible for dampingoff and root-rot diseases of wheat and barley. The pathogens thrive in cool, moist soils and can reach especially high levels in crop …

A Farm-Scale Biodiversity And Ecosystem Services Assessment Tool: The Healthy Farm Index, John E. Quinn, James R. Brandle, Ron J. Johnson

School of Natural Resources: Faculty Publications

Farm management focused on maximizing biomass production results in biological simplification and ultimately a degraded production potential for the future. Despite the large and growing body of evidence pointing to the need to restore biodiversity to farm systems, incorporation of biodiversity and ecosystem services into local agricultural land use decision- making remains limited. The lack of planned and associated biodiversity may reduce resiliency of local managed ecosystems and add management costs; however, the trade-off for individual landowners of greater diversity is increased management complexity and uncertainty. To assist farmers in managing biodiversity and to encourage ecological thinking, we developed the …

Late Gestation Supplementation Of Beef Cows Differing In Body Condition Score: Effects On Cow And Calf Performance, D. W. Bohnert, L. A. Stalker, R. R. Mills, A. Nyman, S. J. Falck, R. F. Cooke

West Central Research and Extension Center, North Platte

A 2-yr study utilizing 120 mature, crossbred (Angus × Herford) cows/year, evaluated the influence of cow BCS and dried distillers grains with solubles (DDGS) supplementation during late gestation on cow performance and productivity of subsequent offspring. Treatments were arranged as a 2 × 2 factorial in a randomized complete block design with 2 BCS and with or without DDGS supplementation. Cows were nutritionally managed to enter the last trimester of gestation with a BCS of approximately 4 (LBCS) or 6 (HBCS) and were thereafter managed in a single herd (initial BCS were 4.4 and 5.7 for LBCS and HBCS treatments, …

Identification Of Sources Of Resistance To Damping-Off And Early Root/Hypocotyl Damage From Rhizoctonia Solani In Common Bean (Phaseolus Vulgaris L.), P. A. Peña, James R, Steadman, Kent M. Eskridge, Carlos A. Urrea

Panhandle Research and Extension Center

Rhizoctonia solani causes economically important root and hypocotyl diseases in common bean throughout the world. Root health is a vital factor in plant development and root diseases would negatively influence water and nutrient uptake as well as cause direct stand reduction and root rot damage to the crop. An efficient common bean screening method to evaluate damping-off and early root/ hypocotyl damage from R. solani was developed and used to identify dry bean lines with levels of resistance to this disease. Two sets of 163 and 111 lines previously evaluated for drought tolerance in Nebraska and Puerto Rico were evaluated …

Thoroughbred Farm Managers' Willingness-To-Pay For Alternative Deworming Regimens In Horses, Marion Angélique Robert

Theses and Dissertations--Agricultural Economics

Parasite control is important to horse health and horse owners should feel highly concerned about the proper treatment of parasites. In the past 30 years, veterinary science has made important advances in treating parasites and provided new products and strategies to optimize treatment and prevention. However, horse owners and managers have been slow to adopt these new recommendations.

This study investigates why the transition has not occurred as expected. It examines issues related to the decision-making process of horse owners and managers as they relate to deworming strategies. In addition, it investigates current deworming approaches as well as attitudes towards …

Accounting For Product Substitution In The Analysis Of Food Taxes Targeting Obesity, Zhen Miao, John C. Beghin, Helen H. Jensen

Department of Agricultural Economics: Faculty Publications

We extend the existing literature on food taxes targeting obesity. We systematically incorporate the implicit substitution between added sugars and solid fats into a comprehensive food demand system and evaluate the effect of taxes on sugars and fats. The approach conditions how food and obesity taxes affect total calorie intake. The proposed methodology accounts for the ability of consumers to substitute leaner low-fat and low-sugar items for rich food items within the same food group. This substitution is integrated into a calibrated demand system in addition to the substitution among food groups, using recent food intake data and existing demand …
