Intricacies In Agronomic Management: The Role Of Interdisciplinary Education, Adam M. Striegel
Intricacies In Agronomic Management: The Role Of Interdisciplinary Education, Adam M. Striegel
Doctor of Plant Health Program: Dissertations and Student Research
As a science, agronomy is built upon the connection of inter-disciplinary fields of study. Management (M) of various discipline considerations (and their subsequent interactions) can be influenced by and have significant effects on genetic by environment (GxE) expression. This has led to the promotion of GxExM systems. However, optimizing GxExM programs requires extensive, interdisciplinary knowledge. To evaluate interdisciplinary training provided in undergraduate education, 11 four-year universities were selected in the United States that offer baccalaureate degree majors in agronomy or crop science. Surveys of undergraduate programs of study were conducted, with all required coursework separated into general degree components (general …

G06-1622 Soybean Inoculation: Applying The Facts To Your Fields (Part Two Of A Two-Part Series), Lori J. Abendroth, Roger Wesley Elmore, Richard B. Ferguson
University of Nebraska-Lincoln Extension: Historical Materials
Why is it that we see soybean yield responses from inoculating with Bradyrhizobia japonicum in some cases but not others?
This publication explains how to distinguish which fields will likely respond to inoculation with B. japonicum from those that will not. Fields are designated as either "new" or "old" based on how often soybean is grown. This designation is one criterion among many in deciding when to inoculate. In general, research trials across multiple locations in Nebraska have shown no yield advantage to re-inoculation.

Nitrogen gas (N2) comprises nearly 80 percent of total atmospheric gases, yet most organisms are unable to use N2 as a source of nitrogen. Legumes, such as soybean, are able to capture atmospheric nitrogen and utilize it through the process of nitrogen fixation. This NebGuide is part one of a two-part series on soybean inoculation. Here, we will investigate how soybean inoculation occurs and which environmental conditions impact nitrogen fixation.

Ec05-185 Grazing Winter Wheat In Nebraska, Tom Holman, Drew J. Lyon, David D. Baltensperger, Ivan G. Rush, Ray Weed
University of Nebraska-Lincoln Extension: Historical Materials
Grazing cattle on winter wheat, often prior to grain harvest, is common throughout the southern Great Plains. Grazing generates about $50 million in income for Texas wheat producers and reduces the risk of growing wheat by providing a substantial income source other than grain. Benefits can be realized by grazing prior to the primary environmental risk period for drought, heat stress, and hail, all of which frequently reduce grain yield while having limited impact on forage production. Cattle also are grazed on winter wheat fields in western Nebraska and the surrounding region. Typically in Nebraska, fall forage would be used …

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 …

Ec02-172 Plumeless Thistle, Kara L. Hilgenfeld, Alex Martin
University of Nebraska-Lincoln Extension: Historical Materials
Plumeless thistle (Carduus acanthoides L.) is one of seven noxious weeds in Nebraska. An introduced invasive broadleaf weed native to Europe and Asia, plumeless thistle currently infests about 65,000 acres in Nebraska. Infestations of plumeless thistle may reduce productivity of pastures and rangeland, where infestations tend to be the largest. Plumeless thistle competes with and suppresses growth of desirable species. Heavy infestations prevent livestock from grazing the area and lighter infestations prevent livestock from eating plants growing near the thistle. Estimates place the annual loss in Nebraska agricultural production due to plumeless thistle at $162,000. Although plumeless thistle is …
Ec02-177 Purple Loosestrife, Stevan Z. Knezevic
Ec02-177 Purple Loosestrife, Stevan Z. Knezevic
University of Nebraska-Lincoln Extension: Historical Materials
Purple loosestrife (Lythrum salicaria) is an introduced invasive weed that isover running thousands of acres of wetlands and waterways in the Midwest. Once purple loosestrife invades a wetland, natural habitat is lost and the productivity of native plant and animal communities is severely reduced. These losses in turn interfere with various levels of the ecosystem and area recreational activities such as fishing, boating and hunting, diminishing revenue from tourism and impairing the social and economic well being of local communities. A single control measure cannot provide long-term, sustainable control of this weed. An integrated approach, using a variety …
Ec02-176 Musk Thistle, Fred Roeth, Steven R. Melvin, Irvin L. Schleufer
Ec02-176 Musk Thistle, Fred Roeth, Steven R. Melvin, Irvin L. Schleufer
University of Nebraska-Lincoln Extension: Historical Materials
Musk thistle (Carduus nutans L.) is an introduced invasive broadleaf weed native to Europe, North Africa, and Asia. In these areas it is a minor weed because natural enemies keep its population low. When the plant was introduced into North America, its natural enemies were left behind. Without these natural checks, the thistle is able to thrive and compete with native vegetation.
Musk thistles aggressively invade all lands in Nebraska. Typical cropland weed control methods are very effective against them; however, land with permanent cover (pasture, range, roadway ditches and wasteland) that is not tilled or treated with a …
