G73-46 Hessian Fly On Wheat, John E. Foster, Gary L. Hein

John E. Foster

This NebGuide discusses the life cycle, control and prevention of the Hessian fly. Plant-safe dates and resistant wheat varieties are also examined. The Hessian fly, Mayetiola destructor (Say), is not native to the United States, but was probably introduced by Hessian soldiers during the Revolutionary War. This insect was given its common name by Americans because of its damage on Long Island in 1779. The pest has become distributed throughout the United States wheat production areas since then. The Hessian fly belongs to the family of insects known as gall midges (Diptera: Cecidomyiidae), a group noted for their habit of …

Segregating Transgenic Grains: Results Of A Survey Among Country Elevators In South Dakota, Bashir Qasmi, Clayton J. Wilhelm, Evert Van Der Sluis

Economics Research Reports

In 2002, cash receipts from crop production in South Dakota totaled $1.76 billion, accounting for 38 % of all receipts of agricultural producers in the state (South Dakota Agricultural Statistics Service, 2003). The three most important crops grown in South Dakota are soybeans, corn, and wheat. In 2001, South Dakota ranked 8th in the production of corn and soybean and 9th in wheat production among the nation's crop producing states (South Dakota Agricultural Statistics Service, 2003). These three crops accounted for 86 % of all cash receipts from marketing crops in the state. Due to the state's reliance on grain …

Optimal Hedge Ratios For Corn Marketing In Eastern South Dakota, Karen Brovold, Bashir Qasmi

Economics Research Reports

In the past, few South Dakota agricultural producers have made use of the futures market to manage their risk exposure. According to a survey, conducted in 1970, only eleven percent of South Dakota producers used futures contracts and five percent used options to market their grain (Shane). The need for producers to become more market-oriented has increased with the passage of the 1996 Freedom to Farm Act. The Freedom to Farm Act gives producers increased flexibility to adjust production based on market incentives. Prices are expected to become more volatile due to changing market conditions over the next few years. …

Wheat Marketing Patterns In South Dakota: Regional Variations, Bashir Qasmi, Kelly Mcdaniel

Economics Research Reports

U.S. Agriculture is going through a transition. Federal spending on farm programs is being curtailed and agricultural policies are being modified to make production of farm commodities responsive to market forces. In this competitive environment, efforts on the part of the commodity groups for market development are becoming increasingly more important. However, in order to devise any market development plan for a commodity, understanding of the present status of the marketing system is important. At the minimum, one needs to know the methods of purchase and sale, types of buyers, shipment destinations, and transportation modes for the commodity. These aspects …

G73-24 Winter Wheat Varieties, Lenis Alton Nelson, R.H. Hammons, P. Stephen Baenziger

University of Nebraska-Lincoln Extension: Historical Materials

The University of Nebraska Institute of Agriculture and Natural Resources conducts wheat variety trials in all parts of Nebraska. Private companies enter their varieties or hybrids in the test voluntarily. Public entries are chosen by the agronomy staff at the University. The current copy of the annual Extension Circular, Nebraska Fall-Sown Small Grain Variety Tests, includes detailed yield, bushel weight, other performance data, and period of years data. Nebraska Cooperative Extension and the University's Agricultural Research Division jointly publish these circulars which are available from Extension offices …

G73-35 How To Plant Wheat, C. R. Fenster, G. A. Peterson

University of Nebraska-Lincoln Extension: Historical Materials

Winter wheat needs a seedbed that is firm enough to provide good seed-soil contact and is moist enough to provide water for germination and seedling establishment. Winter wheat needs a seedbed that is firm enough to provide good seed-soil contact and is moist enough to provide water for germination and seedling establishment. Other Nebraska Experiment Station information is available on how to properly prepare the seedbed.
