Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch
Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch
Masters Theses
Despite the vast production markets for forage and organic products nationally, so far limited work has been done to develop organic forages specifically for Middle Tennessee or the mid-South in general. The present organic research field focuses on vegetable and grain production; however, forage production offers an easier transition for producers moving into certified organic agriculture. The present study seeks to evaluate several forage blends for optimizing forage production under low-input transitional organic conditions. Ideally a forage system could be tailored to the beef cattle operations of Middle Tennessee, the dominant forage consumption market in this region of the mid-South. …

Integrated Strategies For Controlling Warm-Season Turfgrass Weeds, Matthew Thomas Elmore
Masters Theses
Herbicidal inhibitors of 4-hydroxyphenylpyruvate dioxygenase (HPPD) such as mesotrione, topramezone and tembotrione were evaluated in greenhouse experiments for activity against bermudagrass. While topramezone and tembotrione exhibited greater activity than mesotrione, none of these herbicides provided acceptable bermudagrass control. These herbicides reduced leaf tissue chlorophyll and carotenoid pigment concentrations in bermudagrass. Changes in turfgrass pigmentation were quantified using HPLC analogy as well as evaluations of visual bleaching and measurements of chlorophyll fluorescence yield (Fv/Fm). Results indicated that these more expeditious methods of evaluating HPPD-inhibiting herbicide activity (visual evaluations and Fv/Fm) cannot be used …
Irrigation Plus Nitrogen Rate Effects On Hybrid Bermudagrass Hay Yield And Quality, With Preliminary Evaluation Of Ndvi, Tissue, And Soil Nitrate-N Sampling As Diagnostic Tools, Timothy Donald Carter
Irrigation Plus Nitrogen Rate Effects On Hybrid Bermudagrass Hay Yield And Quality, With Preliminary Evaluation Of Ndvi, Tissue, And Soil Nitrate-N Sampling As Diagnostic Tools, Timothy Donald Carter
Masters Theses
A nitrogen fertility study with Vaughn’s hybrid bermudagrass conducted on a Crider silt loam soil (fine, silty, mixed, active, mesic Typic Paleudalfs) over three (3) years (2008-2011) at the Highland Rim Research and Education Center near Springfield, Tennessee is evaluated in this manuscript. Nitrogen applications are evaluated in both irrigated and non-irrigated plots at five (5) different application rates: 0, 56, 112, 168, and 224 kg N ha-1. These rates are applied beginning in late April, and three (3) additional times upon harvests occurring in June, July, and August. Irrigation plots receive enough water to bring total weekly …
