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 …

White Lupin Leads To Increased Maize Yield Through A Soil Fertility-Independent Mechanism: A New Candidate For Fighting Striga Hermonthica Infestation?, Laure Weisskopf, Pollycarp Akello, Roxane Milleret, Zeyaur R. Khan, Fritz Schulthess, Jean Michel Gobat, Renée Claire Le Bayon

All Peer-Reviewed Publications

Nitrogen (N)-deficiency and lack of phosphorus (P) availability are major constraints to maize yields in Western Kenya. In a two-season field study in the lake Victoria basin, we tested the capacity of white lupin (Lupinus albus (L.), cv. Ultra), as a nitrogen-fixing crop with a highly efficient P-acquisition capacity, to increase maize yields when used as a companion or cover crop, or as a source of organic matter. Each experiment was performed on three different fields (Vertisols) differing in N/P availability, previous cropping history and in levels of infestation by the parasitic weed Striga hermonthica (Del.) Benth. Our results show …

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 …

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

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 …
