G87-839 Corn Rootworm Control, Leroy L. Peters, Lance J. Meinke, J. F. Witkowski Jan 1987

G87-839 Corn Rootworm Control, Leroy L. Peters, Lance J. Meinke, J. F. Witkowski

Historical Materials from University of Nebraska-Lincoln Extension

Corn rootworms -- damage they cause, and how to control them.

Three kinds of rootworms attack corn in Nebraska -- the western, the northern, and the southern. The western is the most common and most damaging and can be found over the entire state. The northern is found mainly in the northeastern counties. The southern can be found over the entire state.


G87-838 Management Of Greenbugs In Sorghum (Revised May 1994), Robert J. Wright, Stephen D. Danielson, Zb Mayo Jan 1987

G87-838 Management Of Greenbugs In Sorghum (Revised May 1994), Robert J. Wright, Stephen D. Danielson, Zb Mayo

Historical Materials from University of Nebraska-Lincoln Extension

This NebGuide describes the identification, biology and management options for greenbugs in Nebraska sorghum.

The greenbug is the most important insect pest of grain and forage sorghums in Nebraska. Although numbers fluctuate from year to year, greenbugs are a limiting factor to sorghum yield in most years. Their management is complicated by the fact that greenbugs have been able to evolve populations capable of overcoming plant resistance and organophosphate insecticides, so best management practices continue to change over time.

Another common aphid found in sorghum is the corn leaf aphid. Corn leaf aphids are often mistaken for greenbugs; however, they ...


G87-858 Juniper Blight Diseases, Luanne V. Coziahr, David S. Wysong Jan 1987

G87-858 Juniper Blight Diseases, Luanne V. Coziahr, David S. Wysong

Historical Materials from University of Nebraska-Lincoln Extension

Recognition and control of several needle and twig blight pathogens which attack junipers.

Junipers are widely used throughout Nebraska in both ornamental landscape plantings and windbreaks. Eastern redcedar (Juniperus virginiana), Rocky Mountain juniper (J. scopulorum), and other common juniper species are subject to attack by several needle and twig blight pathogens. It is important to properly identify and separate the diseases involved, as each may require a different procedure for effective control.


G87-831 Identification Of Soil Compaction And Its Limitations To Root Growth, Alice J. Jones, Elbert C. Dickey, Dean E. Eisenhauer, R.A. Wiese Jan 1987

G87-831 Identification Of Soil Compaction And Its Limitations To Root Growth, Alice J. Jones, Elbert C. Dickey, Dean E. Eisenhauer, R.A. Wiese

Historical Materials from University of Nebraska-Lincoln Extension

This NebGuide will help you identify soil compaction and determine if compaction is limiting yield. Soil compaction is primarily caused by working or driving on wet fields. Compaction can develop at or below the soil surface (Figure 1) and can lead to inefficient fertilizer and water use and reduced yields. Observation of crop growth and soil surface conditions can give clues as to the extent of soil compaction.


G87-859 Fertilizer Recommendations For Soybean (Revised August 2006), Richard B. Ferguson, Charles A. Shapiro, Achim R. Dobermann, Charles S. Wortmann Jan 1987

G87-859 Fertilizer Recommendations For Soybean (Revised August 2006), Richard B. Ferguson, Charles A. Shapiro, Achim R. Dobermann, Charles S. Wortmann

Historical Materials from University of Nebraska-Lincoln Extension

Soybean production in Nebraska has expanded significantly over the past twenty years and is second only to corn in area planted, at almost five million acres. In general, the fertilizer requirements for soybean are typically less than for other crops such as corn, sorghum, and wheat. This guide provides recommendations on how to manage soil fertility with fertilizer and lime applications to optimize the profitability of soybean production.
