In this study, Maojian, crushed black tea and zymic Pu'er tea were chosen as representative of non-fermented, fully-fermented and post-fermented tea, respectively. The composition profiles of ethanol/water extracts were compared, and the antioxidant activities in vitro were detected by oxygen radical absorbance capacity (ORAC) and DPPH assay. In order to confirm the contribution of each key functional contributors, recombination model of antioxidant compounds in tea have been built and studied. The results showed that ethanol extracts contained higher contents of tea polyphenol, caffeine and prolamin, and higher antioxidant activities detected by ORAC and DPPH assay, while higher amounts of tea …

Salary Negotiation And Graduates From The Department Of Agricultural Economics, Larry W. Van Tassell
Cornhusker Economics
To better serve our students, one skill set that we as a department have considered incorporating more amply in our curriculum is negotiation skills. Negotiation can be defined as, “[a] give and take process between two or more parties (each with its own aims, needs, and viewpoints) seeking to discover a common ground and reach an agreement to settle a matter of mutual concern or resolve a conflict.” (http:// www.businessdictionary.com/definition/ negotiation.html) One of the first opportunities our students have to experience the negotiation process is in obtaining their first employment out of college and negotiating a fair market wage.

Rescaling Drought Mitigation In Rural Sri Lanka, Emily Burchfield, Nicholas E. Williams, Amanda Carrico
Environment and Society Faculty Publications
Smallholder farmers with limited governmental and institutional support often devise innovative strategies to mitigate the impacts of water stress on agricultural production. These drought mitigation strategies can be more culturally and ecologically suitable than top-down, “technocratic,” strategies. Top-down drought mitigation approaches, however, often link farmers with significant infrastructures, financial resources, and specialized knowledge. Successful rescaling of localized mitigation practices can integrate the benefits of localized mitigation with resources available at larger scales. This paper describes the rescaling of a Sri Lankan drought mitigation practice known as bethma. We focus on the process of rescaling, specifically what is lost and …

The Uneven Influence Of Climate Trends And Agricultural Policies On Maize Production In The Yucatan Peninsula, Mexico, Sofia Mardero, Bridgit Schmook, Jorge Omar Lopez-Martinez, Lizette Cicero, Claudia Radel, Zachary Christman
Environment and Society Faculty Publications
Maize is an important staple crop in Mexico, and the recent intensification of climate variability, in combination with non-climatic forces, has hindered increases in production, especially for smallholder farmers. This article demonstrates the influence of these drivers on maize production trends in the three states of the Yucatan Peninsula using a mixed methods approach of climatic analysis and semi-structured interviews. Climate trend analysis and generalized additive models (GAMs) demonstrate relationships between production and climatic variability, using 1980–2010 precipitation and temperature data. Data from forty interviews with government officials and representatives of farmers' associations (gathered in 2015 and 2016) highlight the …

LSU Master's Theses
The corn earworm (CEW), Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), is a major target pest of pyramided Bt corn and Bt cotton in the U.S. In 2016 and 2017, notable corn ear damage and larval survival of CEW were observed on pyramided Cry1A.105/Cry2Ab2 corn in some fields in northeast Louisiana. The objectives of this study were 1) to determine if the ear damage and larval survival observed in the area were due to resistance development to the Bt proteins in the plants, and 2) if resistance had occurred, to determine the approximate distributions of the resistance in the southern region of …

Is Aging The Important Factor For Sustainable Agricultural Development In Korea? Evidence From The Relationship Between Aging And Farm Technical Efficiency, Jun Ho Seok, Hanpil Moon, Gwanseon Kim, Michael R. Reed
Agricultural Economics Faculty Publications
This paper examines the effects of aging and income subsidies on farm efficiency in Korea by utilizing the Korean Farm Household Economic Survey from 2008 to 2015. A stochastic frontier model with a non-monotonic assumption on the effect of efficiency factors is implemented to reflect a super aging and less developed production structure in Korean agriculture. This study finds continuously decreasing farm efficiency with age, which contradicts the commonly assumed inverted-U relationship between age and productivity. Especially, we find that labor is the most important factor to explain recent farm efficiency losses in Korea. Furthermore, this paper finds that the …

Field Pea Response To Seeding Rate, Depth, And Inoculant In West-Central Nebraska, Strahinja V. Stepanovic, Charles Burr, Julie A. Peterson, Daran Rudnick, Cody F. Creech, Rodrigo Werle
West Central Research and Extension Center, North Platte
Increased market demand and larger adoption of field pea (Pisum sativum L.) in semiarid west-central Nebraska has provided opportunities to replace summer fallow and diversify crop rotations. As a relatively new crop, its response to different seeding practices has not been evaluated in this eco-region. Field pea grain yield response to seeding depth (25, 50, and 75 mm), inoculation with Rhizobium leguminosarum bv. viciae (yes and no rhizobia inoculant), and seeding rates (35, 50, 65, 75, 90, 105, and 120 plants m–2) was investigated in 2015 and 2016 at five sites in Perkins County, NE.

Thinking About The Corn Market, Fabio Mattos
Cornhusker Economics
It was twenty years ago today, in the late 1990s, that the United States was the dominant corn producer and exporter in the world, producing about 240 million metric tons (40 percent of the world total) and exporting close to 50 million metric tons (65 percent of the world total). Brazil, on the other hand, was a minor player in the corn market, producing approximately 25 million metric tons (4 percent of the world total) and exporting barely anything. Many changes have happened and we have a different corn market today. For the 2018/19 crop year, USDA projections show the …
