Small Grains And Field Peas: 2009 Variety Recommendations (2008 Crop Performance Results), Cooperative Extension Service, South Dakota State University

SDSU Extension Circulars

Variety selection is a fundamental element in a sound crop production program. This report contains variety recommendations, descriptions, and yield data for the spring-seeded small grains – hard red spring wheat, oat, and barley, along with the fall-seeded small grain –hard red winter wheat. Key factors in variety selection include yield, yield stability, maturity, straw strength, height, test weight, quality, and disease resistance. Yield is an important factor; however, a variety with good disease resistance, straw strength, and high grain quality may be more profitable in some cases than the highest yielding variety. Disease resistance information is based on reactions …

Best Management Practices For Corn Production In South Dakota: Recordkeeping, James A. Wilson, Kurtis D. Reitsma, David E. Clay

SDSU Extension Circulars

Recordkeeping is an important component of all crop production systems. The time that is spent maintaining careful records can help to improve the production, profit, and overall efficiency of the production enterprise. Records provide information needed to identify successes and failures.

Best Management Practices For Corn Production In South Dakota: Corn Drying And Storage, Richard E. Nicolai

SDSU Extension Circulars

The goal for a corn drying and storage system is to maintain grain quality without impeding harvesting or shipping. This chapter describes the factors that influence grain quality, proper handling techniques, drying procedures, storage management, and safety precautions.

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.

Best Management Practices For Corn Production In South Dakota: Soil Fertility, David E. Clay, Kurtis D. Reitsma

SDSU Extension Circulars

Corn requires sufficient amounts of at least 14 nutrients for optimal production (fig. 7.1). Soil fertility strategies should consider soil residual plant nutrients, cost of fertilizer relative to the value of corn, and management techniques that increase efficiency.

Best Management Practices For Corn Production In South Dakota: Irrigation And Salt Management, Todd P. Trooien, C. Gregg Carlson, Hal D. Werner

SDSU Extension Circulars

In South Dakota, average annual precipitation ranges from less than 13 inches to nearly 30 inches, generally increasing from west to east (fig. 6.1). However, all regions of South Dakota can experience drought. Irrigation can reduce a crop’s dependence on natural rainfall and improve yields. To best capitalize on investment in irrigation equipment, it has been suggested that one should increase plant populations on irrigated land by 2,000 to 3,000 plants per acre (Aldrich et al. 1975). This chapter discusses how much irrigation water to apply and how to manage the salts contained in the water. If you are planning …

Best Management Practices For Corn Production In South Dakota: Tillage, Crop Rotations, And Cover Crops, Dwayne L. Beck, David E. Clay, Kurtis D. Reitsma

SDSU Extension Circulars

Historically, tillage and cultivation were used to manage residue, diseases, insects, weeds, and soil compaction. Tillage equipment that has been used includes molderboard plows, discs, cultivators, rippers, and chisel plows. Conservation practices and innovations in production tools (i.e., planters, herbicides, and genetically modified crops) provide farmers with the opportunity to minimize losses.

Best Management Practices For Corn Production In South Dakota: Seasonal Hazards—Frost, Hail, Drought, And Flooding, Robert G. Hall, Todd P. Trooien, Dennis P. Todey, David E. Clay

SDSU Extension Circulars

Conclusion: Weather conditions such as frost, hail, flood, or drought can severely reduce yields. Effects from these events are manageable to a certain extent, but loss can be expected when these events occur. The degree of loss depends on the severity of the event. Crop insurance has become a common component of corn production in the U.S.; the insurance provides the producer economic protection for uncontrollable events. Producers should consider crop insurance based on the consequences of crop loss.

Best Management Practices For Corn Production In South Dakota: Corn Planting Guide, Robert G. Hall, Kurtis D. Reitsma, David E. Clay

SDSU Extension Circulars

Obtaining maximum profit from a corn crop depends on the timely planting of an appropriate hybrid, at the proper depth, with a planter that evenly spaces the seed. The success of a corn crop is dependent on equipment maintenance, seedbed preparation, the development of a sound fertility and pest management program, and planting the seed. Early planting is best, but temperatures should be warm enough to assure quick germination and emergence, and late enough to avoid hard frosts. Planting-opportunity windows can be narrow due to spring rains or a late warm-up. Time spent in the off-season maintaining equipment and planning …

Best Management Practices For Corn Production In South Dakota: Corn Hybrid Selection, Robert G. Hall, Kurtis D. Reitsma

SDSU Extension Circulars

Selecting a hybrid is one of the most important decisions a producer makes. Hybrid selection should consider yield, maturity resistance to disease and insect pests, and other traits important to individual production systems.

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.

Best Management Practices For Corn Production In South Dakota: Corn Growth And Development, Kurtis D. Reitsma, Sharon Clay, Robert G. Hall

SDSU Extension Circulars

Corn growth is influenced by cultural practices and available natural resources. The rate of growth and development changes during the season (fig. 1.1). In South Dakota, water and nitrogen (N) are important resources that limit yield. Other factors that reduce yield include disease, insects, weeds, and deficiency of other plant nutrients. For example, disease and insect infestations can reduce water and nutrient uptake or severely damage the plant to the point of yield loss. Weeds compete with the crop for water, nutrients, and light. Stress from temperature and water extremes affects nutrient availability, often increasing pest population and occurrence and …
