Wheat (Triticum Aestivum) Nam Proteins Regulate The Translocation Of Iron, Zinc, And Nitrogen Compounds From Vegetative Tissues To Grain, Brian M. Waters, Cristobal Uauy, Jorge Dubcovsky, Michael A. Grusak
Department of Agronomy and Horticulture: Faculty Publications
The NAM-B1 gene is a NAC transcription factor that affects grain nutrient concentrations in wheat (Triticum aestivum). An RNAi line with reduced expression of NAM genes has lower grain protein, iron (Fe), and zinc (Zn) concentrations. To determine whether decreased remobilization, lower plant uptake, or decreased partitioning to grain are responsible for this phenotype, mineral dynamics were quantified in wheat tissues throughout grain development. Control and RNAi wheat were grown in potting mix and hydroponics. Mineral (Ca, Cu, Fe, K, Mg, Mn, P, S, and Zn) and nitrogen (N) contents of organs were determined at regular intervals to …

Evaluation Of Cay-1, An Experimental, Natural Fungicide, For Control Of Strawberry Pathogens, Kenneth J. Curry, Maritza Abril, Anthony J. Delucca, Stephen M. Boue, Barbara J. Smith, David E. Wedge
Faculty Publications
CAY-1 is an experimental, natural product being tested as a potential fungicide. This saponin isolated from Capsicum frutescens interacts with membrane sterols causing leakage of cell components and ultimately cell death in a variety of fungi. CAY-1 and the commercial fungicide captan were tested in an in vitro doseresponse dilution-broth assay. They caused at least 85% growth inhibition of the fungal pathogens Colletotrichum acutatum, C fragariae and C. gloeosporioides when tested at 3.0 μM. Even though CAY-1 strongly reduced the growth of these fungal pathogens in laboratory assays and prevented anthracnose development in detached leaf assays, it did not …

A Preliminary Analysis Of The Effects Of Hr 2454 On U.S. Agriculture, Economic Research Service
A Preliminary Analysis Of The Effects Of Hr 2454 On U.S. Agriculture, Economic Research Service
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
USDA performed a preliminary economic analysis of the impacts of House-passed climate legislation, HR 2454, on U.S. agriculture. The analysis assumes no technological change, no alteration of inputs in agriculture, and no increase in demand for bio-energy as a result of higher energy prices. Therefore, it overstates the impact of the climate legislation on agriculture costs in the short (2012-18), medium (2027-2033), and long-term (2042 to 2048). In USDA’s analysis, short-term costs remain low in part because of provisions in HR 2454 that reduce the impacts of the bill on fertilizer costs. In fact, the impact on net farm income …

Best Management Practices For Corn Production In South Dakota: Corn Grain Harvest, Daniel S. Humberg, Richard E. Nicolai, Kurtis D. Reitsma
SDSU Extension Circulars
Corn (grain) harvest can begin when grain moisture drops below 30%. However, most producers will allow corn to dry in the field until grain moisture is between 18 to 25%. Harvesting corn when grain moisture levels are high can result in excessive drying costs, kernel damage, and harvest loss from improper threshing. Allowing corn to stay in the field too long can result in excess harvest loss from stalk lodging, ear drop, or kernel shattering. An optimal harvest depends not only on the condition of the crop but also on the proper maintenance and adjustment of harvest and grain handling …

Best Management Practices For Corn Production In South Dakota: Corn Insect Pests, Michael A. Catangui, Billy W. Fuller, B. Wade French
SDSU Extension Circulars
Historically, the major corn insect pests have been corn rootworms (northern and western), European corn borer, and black cutworm. Bt-corn hybrids are effective against most of these pests. However, Bt-corn hybrids are not effective against corn leaf aphid, corn root aphid, sap beetles, corn rootworm adults, grasshoppers, white grubs, wireworms, seed corn beetle, and seed corn maggots. These insect pests can reduce corn yields. This chapter discusses the management and biology of important corn insect pests commonly observed in South Dakota.

Local Head Loss Of Non-Coaxial Emitters Inserted In Polyethylene Pipe, Osvaldo Rettore Neto, Jarbas Honorio De Miranda, José Antonio Frizzone, Stephen R. Workman
Biosystems and Agricultural Engineering Faculty Publications
The design of a lateral line for drip irrigation requires accurate evaluation of head losses in not only the pipe but in the emitters as well. A procedure was developed to determine localized head losses within the emitters by the formulation of a mathematical model that accounts for the obstruction caused by the insertion point. These localized losses can be significant when compared with the total head losses within the system due to the large number of emitters typically installed along the lateral line. An experiment was carried out by altering flow characteristics to create Reynolds numbers (R) from 7,480 …

Best Management Practices For Corn Production In South Dakota: Corn Diseases In South Dakota, Martin A. Draper, Marie A. Langham, Sharon Clay, Bradley E. Ruden
SDSU Extension Circulars
Corn diseases can be separated into 1) seed and seedling diseases, 2) root-infecting nematodes, 3) leaf diseases, 4) rusts, 5) stalk rots, and 6) ear and grain molds. Yield losses can result from diseases directly reducing yields or from harvestability, spoilage, or marketing and/or use issues associated with mycotoxin contamination. See Table 9.1 for corn disease management information. Attention to optimal seed quality, hybrid selection, seed treatments, weed and insect control, crop rotation, soil fertility, irrigation, and prompt harvest can reduce disease impacts. This chapter discusses aspects of recognizing and managing South Dakota corn diseases.

Sorghum Grain Mold: Sustainable Pest Management Strategies, Intsormil
Sorghum Grain Mold: Sustainable Pest Management Strategies, Intsormil
INTSORMIL Impacts and Bulletins
Global losses due to grain mold are estimated to be $130 million annually. Sorghum grain mold is caused by a complex of fungal species, the most important being Fusarium thapsinum and Curvularia lunata. An additional 25 fungal genera are secondary invaders. Grain mold reduces the quantity of food available, as the fungus consumes a portion of the grain, and reduces the quality and economic value of what remains by producing pigments and toxins that make the grain less palatable and nutritious. Fusarium spp. and the secondarily invading Aspergillus spp. may produce toxins such as aflatoxins (a highly carcinogenic and …
