G74-171 Summer Annual Forage Grasses (Revised January 1986), Bruce Anderson, Paul Guyer

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses production practices, methods of use, and precautions for using summer annual grasses.

Summer annual grasses are used for summer pasture, green chop, hay, silage, and winter pasture. They are often used as sources of emergency forage. In addition, residues of summer annuals make an excellent seedbed mulch for new stands of perennial grass, particularly on sands.

The summer annual grasses most often used for forage in Nebraska are sudangrass, hybrid sudangrass, sorghum-sudangrass hybrids, and forage sorghums. Foxtail millet and pearl millet are used occasionally. Each of these grasses has unique growth characteristics that require proper management for …

G74-121 Sandbur Control In Field Corn (Revised January 1999), Gail A. Wicks, Robert G. Wilson Jr.

University of Nebraska-Lincoln Extension: Historical Materials

Sandbur can be a major weed problem in cornfields if not properly controlled. This NebGuide discusses mechanical and chemical alternatives for controlling sandbur.

Sandbur is a problem weed on coarse to fine-textured soil. The North Platte Valley, southwest and west central Nebraska, and the Sandhills are areas in the state where sandbur is a major weed problem in corn. Sandbur seldom becomes a primary weed problem in eastern Nebraska. Both field (Cenchrus pauciflorus Benth.) and longspine [Cenchrus longispinus (Hack.) Fern.] sandbur grow in Nebraska.

G74-123 Weed Control In Reduced Tillage Corn (Revised May 1982), Russell Moomaw, Alex Martin, David P. Shelton

University of Nebraska-Lincoln Extension: Historical Materials

Weeds compete with corn plants for water, nutrients and light. Historically, the soil has been extensively tilled to prepare a seedbed and to lessen or remove weed competition. This tillage centered around moldboard plowing.

Results of a recent survey indicate that most Nebraska farmers now use some form of reduced tillage, with the moldboard plow being used on only 11 percent of Nebraska's corn acreage. Reduced tillage is used in many forms.

This NebGuide discusses how to control weeds using the different types of tillage systems.

G74-131 No-Till Corn In Alfalfa Sod, Alex R. Martin, Russell S. Moomaw

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska produces about 1,740,000 acres of alfalfa annually. Corn or grain sorghum usually follows alfalfa in the crop rotation. The moldboard plow or chisel plow are commonly used to break up alfalfa sod for corn planting. The plow is a high consumer of energy, requiring about 2.25 gallons of diesel fuel per acre.

Research conducted in Nebraska has been used to develop a system in which the alfalfa is killed with herbicides and corn is planted directly into the sod without tillage. Plowing is eliminated and energy requirements can be reduced to about 1/4 that used in the conventional plow …
