Herbicides Applied At Or Shortly After Seeding Are Effective For Weed Control In Seedling Buffalograss, Luqi Li, Matthew D. Sousek, Zachary Reicher

Department of Agronomy and Horticulture: Faculty Publications

Herbicides applied shortly after seeding of buffalograss [Buchloe dactyloides (Nutt.) Engelm.] can help reduce weed pressure and maximize establishment of buffalograss. This study evaluated 12 relatively recently developed herbicides for turf safety and weed control when applied at seeding or 0 or 2 weeks after emergence (WAE) of ‘Bowie’ or ‘Sundancer’ buffalograss. Primary weed species on the site were common purslane (Portulaca oleracea L.), redroot pigweed (Amaranthus retroflexus L.), and/or yellow foxtail [Setaria lutescens (Weigel ex Stuntz) F.T. Hubb.]. Regardless of cultivar, untreated checks had53% weed cover by 6 WAE, whereas most of the herbicide treatments resulted …

Synfind: Compiling Syntenic Regions Across Any Set Of Genomes On Demand, Haibao Tang, Matthew D. Bomhoff, Evan Briones, Liangsheng Zhang, James C. Schnable, Eric Lyons

Using Behavioral Economic Insights To Improve Program Design, Christopher Gustafson, Mazbahul Ahamad

Cornhusker Economics

The field of behavioral economics has added important tools and insights to economics that can be used to increase the effectiveness of interventions or research in diverse settings ranging from the United States to East Africa. In this article, we briefly contrast traditional economic tools and newer behavioral economic approaches before providing examples of how insights from behavioral economics into individual behavior can be used to improve the design of programs.

A Population Structure And Genome-Wide Association Analysis On The Usda Soybean Germplasm Collection, Nonoy Bandillo, Diego Jarquin, Qijian Song, Randall L. Nelson, Perry Cregan, James Specht, Aaron Lorenz

Department of Agronomy and Horticulture: Faculty Publications

Population structure analyses and genome-wide association studies (GWAS) conducted on crop germplasm collections provide valuable information on the frequency and distribution of alleles governing economically important traits. The value of these analyses is substantially enhanced when the accession numbers can be increased from ~1,000 to ~10,000 or more. In this research, we conducted the first comprehensive analysis of population structure on the collection of 14,000 soybean accessions [Glycine max (L.) Merr. and G. soja Siebold & Zucc.] using a 50KSNP chip. Accessions originating from Japan were relatively homogenous and distinct from the Korean accessions. As a whole, both Japanese and …

"The Only Thing That Is Constant Is Change": A Brief Overview On How Technology Has Changed Futures Markets Part Ii, Fabio Mattos

Cornhusker Economics

In our previous Cornhusker Economics (10/28/2015) we talked about the emergence of electronic trading in futures markets and new trading practices that came with it. In particular, we discussed spoofing and mentioned the trial in Chicago of a trader accused of "poofing" commodity futures markets. As I write this article, a "breaking news" alert, pops up on my computer screen which informs me that the trial is over and the jury has just reached a verdict. As the Financial Times reports, the trader was found guilty on 12 accounts, "Including intending to defraud other traders by flooding gold, corn, soybeans, …

The Founding Of The Robert B. Daugherty Water For Food Institute At The University Of Nebraska

Daugherty Water for Food Global Institute: Administrative Materials

University of Nebraska President J.B. Milliken drove to Omaha in to meet Robert Daugherty at his home. In the living room, the elder Daugherty was surrounded by Mogens Bay, his three sons and a covey of lawyers. Now 88 years old, the businessman had a reputation for being tough-minded and smart, a man who could intimidate, but also surprise with his ready sense of humor. In his long career, Daugherty had transformed agriculture and the rural landscape into the now familiar polka dot pattern, the signature of the center pivot irrigators Daugherty had popularized in the 1970s. He had started …

Vegetable Production Guide For Commercial Growers, 2016-17, Shubin Saha, Emily Pfeufer, Ricardo Bessin, Shawn Wright, John Strang

Agriculture and Natural Resources Publications

Successful vegetable production generally requires the grower to make daily decisions regarding pest management, irrigation, and cultural practices. Would-be growers unwilling to make serious investments of time (and money) should not attempt to expand beyond a space at the farmers’ market. It is important for vegetable growers to have a market outlet for their product before they choose to start production. Good marketing plans start with the customer and work backward to production. Potential growers should first determine exactly what buyers want, how they want it, and when they want it. They then must determine how these crops should be …
