Nitrogen And Phosphorus Remediation Of Aquatic Garden Plants In Laboratory-Scale Constructed Wetlands., Robert Polomski Aug 2009

Nitrogen And Phosphorus Remediation Of Aquatic Garden Plants In Laboratory-Scale Constructed Wetlands., Robert Polomski

All Dissertations

This research investigated the potential of growing marketable aquatic garden plants that also remediate nursery and greenhouse runoff in a subsurface-flow constructed wetland. The cost of wastewater treatment is offset by the production of revenue-generating horticultural crops. Aquatic garden plants that offer the dual benefits of nutrient remediation and aesthetic value may also be planted in bioretention basins, rain gardens, buffer zones, and filter strips.
Fifteen commercially available aquatic garden plants were grown for 8 weeks in a laboratory scale subsurface wetland in a greenhouse and received nitrogen (N) and phosphorus (P) from Hoagland's nutrient solution every two days for …

Diseases Of Floriculture Crops In South Carolina: Evaluation Of A Pre-Plant Sanitation Treatment And Identification Of Species Of Phytophthora, Ernesto Robayo Camacho Aug 2009

Diseases Of Floriculture Crops In South Carolina: Evaluation Of A Pre-Plant Sanitation Treatment And Identification Of Species Of Phytophthora, Ernesto Robayo Camacho

All Theses

This project was composed of two separate studies. In one study, the species of Phytophthora that have been found associated with diseased floriculture crops in South Carolina and four other states were characterized and identified using molecular (RFLP fingerprints and DNA sequences for ITS regions and cox I and II genes), morphological (sporangia, oogonia, antheridia, oospores, and chlamydospores), and physiological (mating behavior and cardinal temperatures) characters. In addition, sensitivity to the fungicide mefenoxam was determined. In all, 87 isolates from 63 host plants that were collected over a 13-year period (1996 through 2008) were examined. Host plants came from 46 …

Overseeded Bermudagrass Spring Trasition Response To Mowing Height, Nitrogen Rate, Sulfonylurea Herbicide, And Allelopathy, Raymond Mccauley May 2009

Overseeded Bermudagrass Spring Trasition Response To Mowing Height, Nitrogen Rate, Sulfonylurea Herbicide, And Allelopathy, Raymond Mccauley

All Theses

Hybrid bermudagrass [Cynodon transvaalensis Burtt-Davey x C. dactylon (L.)
Pers.] is the preferred turf for golf courses and athletic fields across the southern United
States because of its dark green color, fine texture, good wear and drought tolerance, and
excellent recuperative rate. Despite its many attributes, bermudagrass goes dormant and
turns an unsightly brown color when soil temperatures fall below 10-13oC (50-55super>oF).
Perennial ryegrass (Lolium perenne L.) is often overseeded into bermudagrass in the fall
to sustain acceptable turf quality through the spring months. However, perennial ryegrass
aggressively competes with the bermudagrass for resources in the spring and potentially …

Biology And Ecology Of Wild Radish (Raphanus Raphanistrum), Mayank Malik May 2009

Biology And Ecology Of Wild Radish (Raphanus Raphanistrum), Mayank Malik

All Dissertations

Wild radish ( L.), a facultative winter annual is a troublesome weed in small grain crops of the Southeastern United States. Besides being a weed, it may also be used as a cover crop for weed management due to its production of glucosinolates. Studies were conducted to evaluate the biology and ecology of wild radish as well as its glucosinolate production and its weed management possibilities.
Wild radish emerging in fall months formed a rosette of leaves which aided its winter survival. Plants emerging from December through March that did not form a rosette had minimal survival. Wild radish life …

Root-Zone Characteristics And Bermudagrass Response To Saline Water Delivered By Subsurface Drip Irrigation, Kelsey Gorman May 2009

Root-Zone Characteristics And Bermudagrass Response To Saline Water Delivered By Subsurface Drip Irrigation, Kelsey Gorman

All Theses

Population growth and recurring drought conditions have placed high demands on freshwater resources in South Carolina. Thus, turfgrass irrigation management practices that reduce freshwater use while maintaining quality turfgrass need to be identified.
Previous research in the arid Southwest USA documents water conservation on bermudagrass by using saline water sources and subsurface drip irrigation (SDI) systems. A field-scale facility was constructed in Florence, SC, to evaluate `Tifway' bermudagrass
(Cynodon dactylon (L.) Pers. X C. transvaalensis Burtt Davy) quality, growth, and rootzone characteristics when subjected to saline (3.15 dS m-1) or freshwater (0.07 dS m-1) irrigation, SDI lines spaced 41 or …

Forage Species Alters Animal Performance, Carcass Quality, And Fatty Acid Composition Of Forage-Finished Beef Produced In Summer Months, Jason Schmidt May 2009

Forage Species Alters Animal Performance, Carcass Quality, And Fatty Acid Composition Of Forage-Finished Beef Produced In Summer Months, Jason Schmidt

All Theses

The objective of this study was to evaluate how forages grazed during the summer months alter live animal performance, carcass quality, consumer acceptability and fatty acid composition in finishing beef cattle. Angus-cross steers (n=60) were finished on alfalfa (AL), bermudagrass (BG), chicory (CH), cowpea (CO), and pearl millet (PM) during this two year trial. Using a complete randomized block design, ten 2-ha paddocks were blocked and assigned to forage species (2 reps per species). Each year, steers (n=3) were randomly assigned to paddocks and grazing began when adequate forage growth for individual species was present. Put and take grazing techniques …
