University of Nebraska-Lincoln Extension: Historical Materials

Research description and results of testing for effect of glyphosate herbicide application and the effect of the glyphosate-resistant gene in soybean production. Glyphosate is a popular postemergence herbicide. Glyphosate-resistant soybean technology is gaining acceptance in Nebraska and in U.S. cropping systems; however, potential yield suppression from either genetic differences among varieties, the glyphosate-resistant gene/gene insertion process, or glyphosate is a concern. The first of these could contribute to a yield lag; the latter two could contribute to a yield drag. Research Goals We designed experiments to test for both elements of yield drag: the effect of glyphosate herbicide application and …

Ec02-1565 Biology And Management Of Potato Insects, Robert J. Wright, Gary L. Hein, W. Wyatt Hoback, Alexander D. Pavlista

University of Nebraska-Lincoln Extension: Historical Materials

A variety of insects can damage potatoes in Nebraska. Insects may feed directly on the tubers and damage the harvestable crop, or they may indirectly damage the crop by feeding on leaves or stems. If severe enough, indirect damage may reduce harvestable yield and quality. Insect feeding also may be important because some insects (e.g., aphids) may transmit plant diseases such as viruses when they feed, or others (e.g., psyllids) may inject toxins. This publication reviews the identification, biology, and management of common insect pests of potatoes in Nebraska. The basis for a successful integrated pest management (IPM) program for …

Ec02-179 Managing Livestock Manure To Protect Environmental Quality, Michael A. Reynolds, Brian L. Benham, Richard B. Ferguson, Christopher G. Henry, Charles A. Shapiro, James P. Stack, Charles S. Wortmann

University of Nebraska-Lincoln Extension: Historical Materials

This book covers the land application part of manure management. With increasing regulations, the livestock producer needs to understand the scientific principles that affect manure transformations and how to use these principles to manage the manure for maximum fertilizer value with minimal environmental impact. Improved land application of manure is one part of the solution, but we suggest that the producer evaluate the quantity of nutrients arriving on the farm as feed, animals, and fertilizer compared to the total that is exported. Achieving a nutrient balance will reduce potential environmental hazards often associated with animal agriculture.

Ec02-174 Leafy Spurge, Robert A. Masters, Brady F. Kappler

University of Nebraska-Lincoln Extension: Historical Materials

Leafy spurge is an invasive weed that infests over three million acres in the northern Great Plains and the prairie provinces of Canada. It is commonly found in rangelands, pastures, roadsides, rights-of-way, and woodlands. Leafy spurge can reduce rangeland and pasture carrying capacity by as much as 75 percent because it competes with forages and cattle avoid grazing areas infested with this weed. In North Dakota where leafy spurge infests about 900,000 acres, estimates of direct and indirect losses exceed $100 million each year. In Nebraska, the direct loss in forage value attributed to leafy spurge has been estimated at …
