Sculpted Seeding: A Plant Community Approach To Revegitation, E T. Jacobson, D B. Wark, R G. Arnott, R J. Haas, D A. Tober

IGC Proceedings (1997-2023)

The sculptured seeding technique, an ecological approach to revegetation based on a knowledge and understanding of the natural vegetation of an area, establishes a diverse, effective native plant community capable of regeneration and plant succession. It is intended to match site capability with plant species known to thrive under particular conditions. Sculptured seeding is an option available to land managers interested in establishing and maintaining adapted native species and ecotypes within the limits of current technology and available seed sources. Field procedures for sculptured seedings are quite simple, involving only minor modifications to standard planting methodology. Seed mixtures based on …

Evaluation Of Annual Companion Crops For The Establishment Of Perennial Forage Crops In Eastern Canada, Philippe Seguin, Sandrine St-Pierre-Lepage, Céline Georlette, Caroline Halde, Gaëtan F. Tremblay, Huguette Martel, Ayitre Akpakouma

IGC Proceedings (1997-2023)

The use of companion crops when establishing perennial forages is desirable as it often reduces weed growth and increases forage biomass in the seeding year. In eastern Canada, oat (Avena sativa L.) is the main species used as companion crop; although other species are used, they have not been systematically evaluated. A field study was established in 2019 at three sites in Québec, Canada, to contrast the use of six annual species as companion crops for the establishment of lucerne (Medicago sativa L.)-timothy (Phleum pratense L.) mixtures. Species evaluated include berseem clover (Trifolium alexandrinum L.), annual …

Seeding The Way: A Guide To Restoring Native Plants In Great Salt Lake Wetlands, Emily Tarsa, Rae Robinson, Coryna Hebert, David England, Keith Hambrecht, Chad Cranney, Karin Kettenring

All Current Publications

From densely vegetated marshes to sparse patches of playa vegetation, native plants of Great Salt Lake drive healthy wetlands. They provide habitat, cover, and food for the many birds, amphibians, insects, and mammals that call these wetlands home. Disturbances to these wetlands, such as treating invasive Phragmites australis or building dikes, can impact native plant communities. Reestablishing native vegetation is critical to rebuilding healthy wetlands. Though there is still much to be learned, here we have summarized our knowledge of the "what, where, and how" of native plant revegetation in these wetlands, specifically using native seed. This guide is intended …

Influence Of Herbicides And Irrigation On Tall Fescue Shoot And Root Growth, Dani Mcfadden, Jack Fry, Steve Keeley, Jared Hoyle

Kansas Agricultural Experiment Station Research Reports

When turfgrass stands are under renovation, a common problem is removing weeds prior to seeding because seedling turf does not emerge and compete well with weeds that are present. However, most herbicide labels recommend waiting for a defined period of time prior to seeding. If seeding is done prior to the date prescribed on the herbicide label, seed germination and seedling growth may be inhibited. A greenhouse study was conducted to determine the effects of irrigation prior to seeding on seedling growth after herbicide application. Overall, irrigation had no influence on the impact of herbicides on shoot or root growth …

Emergence And Growth Of Tall Fescue Seedlings After Postemergence Broadleaf Herbicide Application, Dani Mcfadden, Jack Fry, Steve Keeley

Kansas Agricultural Experiment Station Research Reports

Effective weed control prior to seeding is essential for proper turfgrass establishment since competition from weeds can cause sward establishment to fail. Herbicides with multiple active ingredients from different chemical families could increase weed control efficacy, but hinder the establishment of newly seeded turf. Research trials were initiated in the fall of 2020 in Olathe and Manhattan, KS, to determine if tall fescue (Schedonorus arundinaceus) could be seeded earlier after application than stated on the herbicide labels. Overall, this study demonstrated that seeding between 0 to 14 days after an application of carfentrazone-ethyl + MCPP + 2,4-D + …

Testing Label Restrictions On Seeding Timings Of Tall Fescue And Kentucky Bluegrass After Herbicide Application, Dani Mcfadden, Jared Hoyle, Steve Keeley, Zane Raudenbush

Kansas Agricultural Experiment Station Research Reports

During a lawn renovation, weeds are often a major problem because they grow more aggressively than seedling turf. Turfgrass seedlings need starter fertilizer and plenty of water for proper establishment, which makes an ideal environment for weeds to thrive as well. With current herbicide label restrictions, there are limited weed control strategies during the critical establishment period. Research trials were initiated in the fall of 2019 in Manhattan, KS, to determine if tall fescue (Schedonorus arundinaceus) and Kentucky bluegrass (Poa pratensis) could be seeded into a stand at different intervals after herbicide application before restrictions on …

Use Of Auto-Germ To Model Germination Timing In The Sagebrush-Steppe, William C. Richardson, Dallin R. Whitaker, Kyler P. Sant, Nicholas S. Barney, Ryan S. Call, Bruce A. Roundy, Zachary T. Aanderud, Matthew D. Madsen

Articles

Germination timing has a strong influence on direct seeding efforts, and therefore is a closely tracked demographic stage in a wide variety of wildland and agricultural settings. Predictive seed germination models, based on soil moisture and temperature data in the seed zone are an efficient method of estimating germination timing. We utilized Visual Basic for Applications (VBA) to create Auto‐Germ, which is an Excel workbook that allows a user to estimate field germination timing based on wet‐thermal accumulation models and field temperature and soil moisture data. To demonstrate the capabilities of Auto‐Germ, we calculated various germination indices and modeled germination …

Restoration Of Native-Dominated Plant Communities On A Centaurea Stoebe L.-Infested Site, Neil W. Macdonald, Kaitlyn M. Dykstra, Laurelin M. Martin

Funded Articles

Questions: Restoring native-dominated plant communities often requires controlling invasive species, reintroducing native species, and implementing continued management practices. Can single herbicide applications to control Centaurea stoebe L. encourage establishment of seeded native species more effectively than a single mowing? Can annual hand pulling to control C. stoebe favor the persistence of seeded native species? Can mid-spring burning reduce C. stoebe and increase native forbs and grasses? After eight years, will the restored plant communities differ from those in untreated areas?

Improving Post-Wildfire Seeding Success Using Germination Modeling And Seed Enhancement Technologies, William Charles Richardson

Theses and Dissertations

Arid and semi-arid rangelands are important ecosystems that are consistently degraded through disturbances such as wildfires. After such disturbances, the invasion and dominance of annual grasses, like cheatgrass (Bromus tectorum L.), can lead to an overall loss of ecosystem productivity and an increase in fire frequency. To reduce weed dominance, native and introduced perennials species are typically be seeded in the fall. High mortality is seen from these seeded plant communities due to germinated seed being exposed to freezing, drought, fungal pathogens, and other biotic and abiotic stressors during winter months. We utilized wet-thermal accumulation models to first further …

Patch Seeding On An Extensive Green Roof: Initial Experiment On Microclimate Impacts, Zhuqing Xu

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The green roof provides not only aesthetic values but also many ecological benefits. In North America, seeding or reseeding with native species becomes increasingly popular as a result of its high efficacy and low cost. The extreme temperature and a lack of water on the green roof impose restrictions on seeds germination that determines the success of a seeding program.

The study started on June 1 and was completed by July 15. Five Great Plains native species were hand-seeded in two blocks on Larson Building green roof, along with two blocks set up in the greenhouse at University of Nebraska-Lincoln …

Effects Of Non-Surface-Disturbing Restoration Treatments On Native Grass Revegetation And Soil Seed Bank Composition In Cheatgrass-Invaded Sagebrush-Steppe Ecosystems, Alexandra D. Reinwald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The sagebrush-steppe communities of the Great Basin have been dramatically transformed by the invasion of the non-native annual grass cheatgrass. In many areas of the Great Basin, this invasion has resulted in the loss of native plant species and ultimately the conversion to cheatgrass-dominated communities. As healthy sagebrush communities provide multiple ecosystem services such as diverse wildlife habitat, forage for cattle grazing, and water filtration, restoration of these communities is a high priority to landowners and land management agencies. Established perennial grasses can successfully compete with non-native annual grasses and increase the resistance of plant communities to invasion by non-native …

Prairie Restoration And Species Diversity: A Comparison Of Propagation Success Between Seeded And Planted Forbs, Julie A. Widinski

All Student Theses

Prairie ecosystems used to dominate Illinois’ landscapes, providing some of the most organically rich soils in the world, supplying homes to hundreds of native species, and conserving soil and water. The deep rooted forbs prevent water runoff and soil erosion. Economically the prairies have provided medicines, commercial forbs, and aesthetically pleasing landscapes for humans. Society is dependent on the rich soils these prairies have provided for agriculture and for prevention of erosion and water runoff. With less than one tenth of one percent of Illinois prairies still remaining, successful prairie restoration is of the utmost importance. In order to achieve …

Weed Suppression With Grazing Or Atrazine During Big Bluestem Establishment, B. Keith Lawrence, Steven S. Waller, Lowell E. Moser, Bruce Anderson, Larry L. Larson

Department of Agronomy and Horticulture: Faculty Publications

Weed competition is a major factor causing warm-season grass seeding failures in rangeland and cropland. With a limited number of herbicides available for weed control, grazing may reduce competing vegetation in seedings and serve as an alternative to herbicides. Many immature needy forbs and grasses are palatable to cattle and contain high nutrient levels. Research was conducted (RCBD, 4 reps) comparing grazing by yearling cattle with chemical suppression [atrazine (6-chloro-N-ethyl-N’- (methylethyl)-1, 3, 5-triazine-2, 4-diamine)] for weed control in big bluestem (Andropogon gerardii var. gerardii Vitman) seedlings at Mead, Nebr. on a Sharpsburg silty clay loam (fine, montmorillonitic, mesic Typic …

Agronomy Notes

TEST YOUR SOIL AND SUPPLY THE SUGGESTED LIMING AND FERTILIZER MATERIALS.

A soil test is the first step to profitable small grain production. A pH of 6.0 to 6.5 is best, and nitrogen should be applied both in the fall and spring. If your small grains are part of a double cropping system the P and K requirements for both crops should be applied in the fall.

General And Specific Combining Ability Of Five Alfalfa Clones Including Reciprocal Effects For Seedling Vigor And Seed Yield, Edwin Theodore Bingham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of F₁ hybrids for commercial production of such cross-pollinated crops as corn, sorghum, sugar beets, onions, and pearl millet suggests the feasibility of using this technique for alfalfa. Production of F₁ hybrids of commercial value is dependent on the use of breeding material expressing good combining ability. In order to obtain precise estimates of combining ability for quantitative characters in alfalfa, it is necessary to produce all possible single crosses among a number of parents. The single cross seed required is difficult to obtain due to the vegetative reproduction and isolation required; and, subsequently, limited testing …

Effects Of Season, Spacing And Intensity Of Seeding On Emergence And Survival Of Four Wheatgrass Species In Central Utah, Edwin B. Abbott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rehabilitation of deteriorated and abused range lands is being accomplished with greater success each year by the aid of better methods of seeding which include seedbed preparation, intensities of seeding, implements for planting and improved methods of eliminating competition. Much more information is needed, however, in order to recommend suitable methods and species for seeding various vegetation types and sones with reasonable reliability. Throughout the arid and semi-arid range lands, moisture is the principal factor limiting satisfactory seedling establishment. Special attention should therefore be given to more efficient utilization of the moisture supply. Closely related species or species with similar …

Bindweed Eradication In Nebraska, N. S. Hanson, F. D. Keim, D. L. Gross

Nebraska Agricultural Experiment Station: Historical Circulars

Bindweed, which is easily recognized by its creeping, entwining habit of growth, is Nebraska's most destructive weed because of its effect on crop plants. Its total annual cost to the agricultural industry of the state is several million dollars, which ultimately affects all those citizens who depend directly or indirectly upon income from agriculture.

Bromegrass Production In Nebraska, A. L. Frolik, L. C. Newell

Nebraska Agricultural Experiment Station: Historical Circulars

A native of the old world, from central Europe to China, bromegrass was introduced into the United States about 1884. In 1899, the Nebraska Agricultural Experiment Station reported that "all things considered, it is the most promising cultivated pasture grass for this state that has been tested on the Station farm." Early records of the Station show that considerable seed was distributed to farmers during the period from 1898 to 1902. A few of these early plantings are still in existence. Bromegrass increased in popularity in Nebraska until about 1910. Very little interest was shown in this crop during the …

Nebraska Pastures: Seeding And Management, A. L. Frolik, E. F. Frolik

Nebraska Agricultural Experiment Station: Historical Circulars

Pastures are an important source of feed in the livestock industry. Approximately 70 per cent of the income from Nebraska farms is from the sale of livestock and livestock products, and for this reason consideration should be given to the maintenance of good pastures. Poor pastures, like other poor crops, are expensive. Good grass cover is also an effective means of conserving the soil resources.

Alfalfa Investigations, T. A. Kiesselbach, Arthur Anderson

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

The purpose of these alfalfa investigations has been to determine the relation of variety, source of seed, and cultural practice to the yield and quality of hay produced. Due to the high initial cost of seeding, the inconvenience and wastefulness of losing a stand prematurely, and the superiority of properly-made hay, an understanding of these relationships is very important.
