Overseeding annual ryegrass and cereal rye into soybean for winter forage and as a cover crop for weed control and soil conservation
(University of Missouri--Columbia, 2005)
was grown as a subsequent crop. Soybean yield was not altered by overseeding annual ryegrass or cereal rye. All treatments yielded over 2,500 kg ha-1 for the season (with a high of 4,200 kg ha-1), which would supply much needed pasture for winter grazing...

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] One of the distribution network problems faced by industrial organizations today is coordinating the movement of goods on a global scale. The flow of ...
Utilization of forages in beef cow-calf nutrition
(University of Missouri--Columbia, 2007)
second 2-year study compared performance differences between spring-calving crossbred beef cows wintered on one of three treatments: grass hay only, grass hay with grain supplementation, or non-endophyte infected stockpiled tall fescue (STF) pasture. Cows...
Historical rainfall analysis and climate implications for agriculture in midwest United States
(University of Missouri--Columbia, 2021)
A historical analysis of precipitation using 72 years of data from Midwest stations focuses on the implications of climate change for agricultural interests. The number of precipitation events, consecutive days of ...
Structural/functional insights derived from studies of human and zebrafish CFTR orthologs
(University of Missouri--Columbia, 2018)
with two distinct subconductance levels, small conductance O1 state and large conductance O2 state, respectively. Intriguingly, the preferred gating transition C→O1→O2→C over C→O2→O1→C (namely the O1O2 phenotype) as reported previously for R352 mutations...
Metabolically activated heterocyclic N-oxide compounds for killing and visualizing hypoxic cancer cells
(University of Missouri--Columbia, 2009)
on the benzotriazine-1-oxide substrates involving various 3-aryl, and 3-cyclopropyl boronic acid to build a series of TPZ analogues. In addition to this work, we prepared novel 3-cyclopropyl-1,2,4-benzotriazine 1,4- dioxide which damages DNA under bioreductive hypoxic...
Effects of forest fragmentation on reproductive effort and productivity of Indigo buntings (Passerina cyanea)
(University of Missouri--Columbia, 2005)
Forest fragmentation creates edge habitat that attracts nest predators that lower reproductive success and force birds to renest. To determine if predation-induced renesting causes a decline in condition of females and ...
Identifying bioactive compounds from switchgrass (panicum virgatum L.) by global metabolomic analysis
(University of Missouri--Columbia, 2018)
) to compare the chemical profiles between varieties of switchgrass and 2) to identify and characterize the valued bioactive compounds in switchgrass using global metabolomics approach (XCMS Online). The compounds extracted from switchgrass were analyzed...
A victory long in the making : divestment from South Africa at the University of Missouri
(University of Missouri--Columbia, 2019)
at the flagship campus in Columbia. Concurrently, I look at the reasons why the University of Missouri's administrators actually decided to divest in 1987. My first chapter covers the first two phases of divestment at Mizzou; here Students began calling...
Monitoring motivation and academic growth in writing for young English language learners

Cut-leaved leaved teasel is an invasive, exotic, and noxious weed in Missouri. Biennial plant infest roadsides and undisturbed areas. Studies regarding seed biology, detection, and control measures were conducted to improve ...
Utilizing on-line surveys to gather data: an application to help evaluate Missouri's interpretive programs
(University of Missouri--Columbia, 2005)
Most state and federal agencies involved in the management of natural resources offer educational programs that serve several purposes. In Missouri, the Departments of Conservation and Natural Resources play this vital ...
Nested association mapping and accuracy of predicting genomic breeding value for agronomic and seed composition traits in three interspecific soybean populations
(University of Missouri--Columbia, 2019)
Given the narrow genetic base of soybean, discovering useful traits in exotic germplasm could increase the diversity in the current elite gene pool. However, it is essential to characterize beneficial alleles from the wild ...
