Exporting Vegetables In Bulk : Reducing Supply Chain Costs Without Compromising Quality, Helen Ramsey, Dennis Phillips

Bulletins 4000 -

Increased competition, a strong Australian dollar and increased production costs have seen Australian grown vegetables steadily lose their share in traditional export markets.

As competition increases, we need to investigate production and handling techniques that improve our price and quality competitiveness.

Improving the effi ciency of the supply chain to export markets is one way Australian growers can reduce production and shipping costs and improve product quality.

Pasture Condition Guide For The Ord River Catchment, K Ryan, E Tierney, P Novelly

Bulletins 4000 -

This guide has been produced as a tool for assessing pasture condition over a range of pasture types in the Ord River catchment. A pasture type is a distinctive mix of plant species, soil type and landscape position. For example, the Mitchell Grass Alluvial Plain Pasture type is a mixture of Mitchell grasses and other species occurring on black soil alluvial plains.

Pasture condition is an important factor affecting the potential of the rangelands for animal production and is a useful indicator for the sustainability of production.

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.

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.

Wild radish ( L.), a facultative winter annual is a troublesome weed in small grain crops of the Southeastern United States. Besides being a weed, it may also be used as a cover crop for weed management due to its production of glucosinolates. Studies were conducted to evaluate the biology and ecology of wild radish as well as its glucosinolate production and its weed management possibilities.
Wild radish emerging in fall months formed a rosette of leaves which aided its winter survival. Plants emerging from December through March that did not form a rosette had minimal survival. Wild radish life …

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 …

Changes In Producer Attitudes Towards Windbreaks In Eastern Nebraska, 1983 To 2009, Kim Tomczak

Department of Environmental Studies: Undergraduate Student Theses

Abstract Windbreaks are rows of trees or shrubs arranged on the landscape to reduce wind speed. In agricultural landscapes we find them as farmstead windbreaks, livestock windbreaks and field windbreaks. While farmstead and livestock windbreaks are well accepted by the agricultural community, field windbreaks are often viewed differently. A 1982 study of the attitudes of farmers in Eastern Nebraska indicated that many of the producers were around the age of 50 and that they used different types of windbreaks. This study repeated that survey in the same. When compared to data from 1982, farmers today are not educated about the …

The Politics Of Genetically Modified Organisms: Global Rules, Local Needs, Ximena Gonzalez

Independent Study Project (ISP) Collection

Biotechnology in regards to agriculture is complex and cannot be judged by a single factor. Exporters of GM foods have their reasons for exportation, and importing countries have their reasons to accept them. There is not a unified reason for acceptance or rejection. Countries may accept or reject for economic, social, or political reasons. Other countries may accept or reject for environmental and/or health reasons. However, there is the inevitable factor of influence. Some countries like the United States, and supernational powers like the European Union are major elements to the decision making process of developing countries. When it comes …
