G93-1136 Potato Leafhopper Management In Alfalfa, Stephen D. Danielson, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide explains how to detect and manage potato leafhoppers to minimize alfalfa damage.

The potato leafhopper is capable of causing serious damage to alfalfa in Nebraska. This insect overwinters in the gulf states and migrates northward in the spring, usually in April or early May. During the summer months, several generations develop while feeding primarily on legumes such as alfalfa and clover. Although an occasional host, soybeans rarely suffer economic damage, particularly with the pubescent (i.e. hairy) soybean varieties that are commonly grown today. Infested potatoes also can sustain economic damage from this insect. Generally, the potato leafhopper is …

G93-1167 Spider Mite Management In Corn And Soybeans, Robert J. Wright, Ronald C. Seymour, Leon G. Higley, John B. Campbell

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes the two common spider mites found in Nebraska corn and soybeans, their natural enemies and management.

Two species of spider mites, the Banks grass mite and twospotted spider mite, commonly feed on Nebraska corn. Banks grass mites (BGM) feed almost exclusively on grasses, including corn and sorghum. Twospotted spider mites (TSM) not only feed on many species of grasses, but also on soybeans, fruit trees and a variety of vegetables and ornamental plants. Although these two species are somewhat similar in appearance, they differ in several biological characteristics and in their susceptibility to pesticides.

Banks grass mites …

G90-963 Narrow-Row Soybeans, Roger Wesley Elmore, Russell S. Moomaw, Roger Selley

University of Nebraska-Lincoln Extension: Historical Materials

Narrow-row spacing of soybeans may be a profitable practice with modern herbicides and new lodging-resistant varieties. This NebGuide describes considerations for producing narrow-row soybeans. Early in this century crop row spacing was determined by the breadth of the animals used to work the fields. Spacing had an impact on methods of weed control and the varieties of soybeans developed. Even a decade ago row spacing was determined by tractor tire size since cultivation was required. Also, the tall varieties of soybeans lodged severely in narrow-row systems. However, the broad spectrum of herbicides now available and lodging-resistant soybean varieties have made …

G90-994 Full-Fat Soybeans For Pigs (Revised July 1992), Duane Reese

University of Nebraska-Lincoln Extension: Historical Materials

Several factors should be considered when feeding full-fat soybeans to swine, including nutrient composition, performance, economic considerations and diet formulations.

Soybean meal is the most common supplemental protein source used in pig diets. It is widely available, and often produces the most economical gains when compared with other protein sources. For various reasons, feeding full-fat soybeans to pigs, instead of soybean meal, may be an attractive alternative.

G90-974 The Beaf Leaf Beetle In Soybeans (Revised September 1994), Thomas E. Hunt, J. F. Witkowski, Robert J. Wright, Keith J. Jarvi

University of Nebraska-Lincoln Extension: Historical Materials

The identification and life cycle of the bean leaf beetle are discussed along with scouting techniques, economic thresholds, and cultural control tactics.

The bean leaf beetle is a common insect found in Nebraska soybean fields. The insect also feeds on peas, snap beans, and dry beans. Although present in alfalfa and sweet clover in the early spring before soybean emerges, the insect is not known to damage either legume.

Use integrated pest management (IPM) when planning how to reduce bean leaf beetle damage. Integrated pest management is a sustainable approach to managing pests by combining biological, cultural, physical, and chemical …

G89-953 Soybean Chlorosis Management, Edwin J. Penas, Richard A. Wiese

University of Nebraska-Lincoln Extension: Historical Materials

Four management ideas that make it possible to grow soybeans on alkaline soils are covered here.

Chlorosis (yellowing) in soybeans can be a problem wherever soybeans are grown on alkaline soils in Nebraska. Serious chlorosis is likely to occur when the pH of these alkaline soils is 7.5 or higher. Soybean chlorosis problems occur in the Platte and Elkhorn River Valleys and, to a lesser extent, in the Republican and Loup River Valleys, and on high lime soils in central and western Nebraska. Not all high pH soils cause chlorosis of soybeans even though they are alkaline.

Soil tests of …

G85-770 An Introduction To Grain Options On Futures Contracts, Lynn H. Lutgen, Lynne A. Todd

University of Nebraska-Lincoln Extension: Historical Materials

This publication, the third of six NebGuides on agricultural grain options, explains how to use futures options as a marketing tool.

A new agricultural marketing tool is available to farmers. A futures agricultural option is much like an insurance policy. It is a marketing alternative that gives farmers insurance against unfavorable price moves, but allows producers to take advantage of favorable price moves. To better understand terms used in this paper, please see NebGuide G85-768, Basic Terminology For Understanding Grain Options.

G85-762 Soybean Yield Loss Due To Hail Damage, Charles A. Shapiro, T.A. Peterson, A.D. Flowerday

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses the methods used by the hail insurance industry to assess yield loss due to hail damage in soybeans. A hailstorm can cause yield losses in soybeans ranging from slight to total destruction of the crop. Extensive research has been conducted to accurately predict the effects of hail damage on soybean yields. Results from these studies are used by hail insurance companies to assess yield losses and consequent adjustment made to clients. The information in this NebGuide should be valuable to producers facing replant decisions, and may also be useful in cases of insect damage. Yield loss predictions …

G84-737 Soybean Inoculation -- When Is It Necessary?, Roger Wesley Elmore

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses when soybean seed should be inoculated and why, and provides recommendations on inoculant types to use. Soybeans can obtain up to half of their nitrogen needs from the air when nitrogen-fixing rhizobia bacteria are present in the soil. Nitrogen fixation is a result of the symbiotic (beneficial to both) relationship of rhizobia and plants. Establishing rhizobia (inoculation) in a field that has never grown soybeans is needed to insure nitrogen fixation. Reinoculation may be necessary in fields with a past history of soybeans.

G84-687 Soybean Planting Date: When And Why, Roger Wesley Elmore, A. Dale Flowerday

University of Nebraska-Lincoln Extension: Historical Materials

Soybeans differ from corn and sorghum in their response to planting date. This NebGuide provides guidelines that are helpful in making planting decisions for soybeans. Soybean response to planting date is important not only in years when planting is delayed by inclement weather, but also when weather does not disrupt the normal planting season. When planting is delayed, and in doublecrop situations, correct crop and variety planting decisions are necessary to obtain maximum yields. Early season freezes, hail storms, flooding, and other situations can reduce crop stands to a point where late planting is necessary. When planting is not delayed …

G83-681 Velvetleaf, Fred Roeth, Russell Moomaw, Alex Martin, Orvin Burnside

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide provides guidelines on how to control velvetleaf by prevention, cultural and mechanical methods, and by use of recommended herbicides.

Velvetleaf (Abutilon theophrasti Medic.), a member of the Mallow family, is related to cotton, hollyhocks, and numerous weeds. Other common names include buttonweed, Indian mallow, butterprint, piemarker, velvetweed, and cottonweed. The preferred name, velvetleaf, amply describes its velvety-textured, hairy-surfaced leaves.

A native of China and presumably introduced into the U.S. from India as a fiber crop, this annual weed is adapted to cropland throughout most of the United States. Over the past 10 years, velvetleaf has increased dramatically …

G82-602 Predicting The Last Irrigation For Corn, Grain Sorghum And Soybeans (Revised August 1991), Norman L. Klocke, Dean E. Eisenhauer, Terry L. Bockstadter

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide presents criteria and "rules of thumb" for predicting the last irrigation for corn, grain sorghum and soybeans.

Determining when to apply the last irrigation of the season is an important water management decision. One extra irrigation may mean wasting an additional one to three inches of water and two to five gallons of diesel fuel per acre. On the other hand, applying that one extra irrigation could mean several bushels per acre in crop yield.

G82-601 Using Phosphorus Fertilizers Effectively, E.J. Penas, D.H. Sander

University of Nebraska-Lincoln Extension: Historical Materials

For most effective use of phosphorus, the fertilizer needs to be placed to ensure quick contact by growing roots and minimal contact with the soil.

Phosphorus (P) fertilizers are second only to nitrogen fertilizers in importance for growing crops in Nebraska. However, the principles affecting efficient phosphorus use are totally different. Nitrogen is a mobile nutrient both inside the plant and in the soil, while phosphorus moves very little in the soil. In addition, total plant phosphorus requirements are much lower than those of nitrogen. Plant leaves commonly contain ten times more nitrogen than phosphorus. However, phosphorus is concentrated in …

G81-551 Ecofarming: Spring Row Crop Planting And Weed Control In Winter Wheat Stubble, Gail A. Wicks, Norman L. Klocke

University of Nebraska-Lincoln Extension: Historical Materials

Weed control, stubble management and planters for planting in winter wheat stubble are covered here.

Planting corn, sorghum or soybeans into untilled, weed-free winter wheat stubble that is 10 months old is an accepted practice in the Central Great Plains States. In Nebraska, this system is known as ecofallow. Treating the stubble with herbicides following wheat harvest (ecofallow) offers several advantages:

Weed and volunteer wheat growth can be eliminated. Weed growth robs valuable moisture that could be used by the next year's crop.

Standing stubble provides an excellent snow trap during the winter. Snow melt can provide moisture for the …

G79-430 Oat Production In Nebraska (Revised March 1992), Russell Moomaw, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

Information is provided for various oat production practices including seed selection, fertilizing, planting, weed control and harvest. Oats were among the first crops grown by pioneers who settled eastern Nebraska. As recently as 1950, Nebraska produced 2.7 million acres of oats. Acreage has declined steadily, however, and in 1990 there were just 300,000 acres. Oats are grown throughout the state, with the majority being in eastern Nebraska where the cool, moist climate provides for the best growth. The feed value of oats also favors its production in northeast Nebraska where swine, dairy cattle, and beef cattle production are heavy. An …

G78-390 Right Crop Stage For Herbicide Use Alfalfa, Sugarbeets, Soybeans, And Fieldbeans (Revised January 1987), Robert G. Wilson, Alex Martin

University of Nebraska-Lincoln Extension: Historical Materials

If you are using herbicides on alfalfa, sugarbeets, soybeans, or fieldbeans, information in this Guide will help you apply them at the proper time for best weed control with a minimum of crop injury. Proper timing of postemergence herbicides is essential to achieve maximum weed control with minimum crop injury. As field crops grow and mature, their tolerance to herbicides changes. As a general rule, annual and biennial weeds are more susceptible to postemergence herbicides when they are in the seedling stage, becoming increasingly difficult to control as they mature. The grower is thus faced with the problem of when …

G77-361 Using Starter Fertilizers For Corn, Grain Sorghum, And Soybeans, Edwin J. Penas, Gary W. Hergert

University of Nebraska-Lincoln Extension: Historical Materials

Starter fertilizer may increase early growth of corn and grain sorghum. Grain yield increases from starter nutrients are most likely on low phosphorus soils and some sandy soils.

Proper use of a starter fertilizer is an important management tool for crop producers striving for top yields. While the use of a starter fertilizer can be important for crop production on many soils, it is more important for corn production on irrigated sandy soils than on fine textured soils.

G76-294 Band Application Of Herbicides (Revised March 1986), Russell S. Moomaw, Alex Martin

University of Nebraska-Lincoln Extension: Historical Materials

Many row crop producers prefer to use hebicide band applications because of reduced costs. Savings can be substantial with the more expensive materials. Properly applied, band applications of herbicides can satisfactorily protect the crop from weed growth. Herbicide row banding can be done either at crop planting time or postemergence after the crop and weeds have emerged.

G74-113 A Quick Test For Atrazine Carryover (Revised March 1989), Alex Martin, R.N. Stougaard, Patrick J. Shea

University of Nebraska-Lincoln Extension: Historical Materials

How can you tell if you have atrazine carryover in your fields? Plants grown in soil samples can tell.

Residues of atrazine may remain in the soil and affect some susceptible crops the next year. Crops most often affected include soybeans, field beans, sugarbeets, alfalfa, oats, wheat and many broadleaf horticultural crops.

Attempts to predict the extent of carryover and damage to sensitive crops the year following atrazine use have been only partially successful. The rate of atrazine disappearance and, therefore, the amount remaining the next year, is affected by soil texture, pH and organic matter content, as well as …

Ec31-133 The Management Of Nebraska Soils (Revised March 1936), P.H. Stewart, D.L. Gross

University of Nebraska-Lincoln Extension: Historical Materials

The agricultural lands of this country are its greatest natural resource. History points out that nations with vast areas of good farm land are most likely to prosper and survive over long periods of time. Local communities, too, prosper and flourish in proportion to the productiveness of the surrounding land. Schools, social life, and business develop best in areas where the land is productive and properly managed and conserved.

Nebraska, in common with other states, has suffered by the depletion of soil fertility. The reduction in acres in legumes and grasses, and the deplation of the organic matter in the …
