Recommendations for tree establishment in tall fescue-based silvopasture
(University of Missouri--Columbia, 2008)
-free controls, while pitch x loblolly pine growth was similar in grasses and in vegetation-free plots. Neither dry matter yield of grasses nor tall fescue's endophyte association affected tree growth. Results suggest that weed control should extend a minimum...
Corn tissue nutrient response related to soil health and fertility
(University of Missouri--Columbia, 2021)
fertilizer decisions. End of season yield response to fertilizer may be improved by using both of these two diagnostic tools. Research conducted in 2019 and 2020 on 91 producer corn fields in Missouri encompassed many soil types, management practices...
Influence of herbicide applications and common pasture weeds on total forage yield and nutritive values in tall fescue pastures and hayfields in Missouri
(University of Missouri--Columbia, 2009)
these species are not consumed by cattle and continue to be a problem in Missouri tall fescue pastures and hayfields....
Integrating cover crops into crop rotations in upstate Missouri
(University of Missouri--Columbia, 2018)
"There is an increasing emphasis on management strategies such as reduced tillage, use of cover crops, and implementation of conservation practices (i.e. terraces, no-till, and cropping systems) in Missouri cropping systems. By combining best...
Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)
compared fall herbicide applications to early spring applications. Therefore, field experiments were conducted in both no-till corn and soybean fields from 2004 through 2006 in central, northwest, and northeast Missouri. Herbicide applications were made...
Molecular characterization of soybean squalene synthases (GmSQSs) and genetic engineering for enhanced phytosterols in Arabidopsis seeds
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Squalene synthase (SQS), which converts fanesyl diphosphate (FPP) to squalene, represents a crucial branch point of the isoprenoid pathway and is considered a key enzyme...
Characterization of soybean rooting depth in response to different environmental conditions
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Soybean (Glycine max (L.) is currently grown throughout the world because it has been adapted to many environments and because of the high protein and oil content...
Consequences of plant water limitation for aphids, their natural enemies, and insect communities
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Climate change is causing an increase in drought events around the world. Water limitation affects the quality and quantity of plant resources for herbivorous insects, resulting...
Impact of alternate host phenology amd alternate hose-transgenic corn interactions on the Western corn rootworm (Coleoptera: Chrysomelidae)
(University of Missouri--Columbia, 2006)
With the increasing adoption of transgenic maize with resistance to rootworms, combined with glyphosate tolerance, as a control tactic for western corn rootworm, Diabrotica virgifera virgifera LeConte, an understanding of the effect of alternate...
Partial characterization of Bt resistance and the bacteriome of western corn rootworm
(University of Missouri--Columbia, 2018)
Western corn rootworm (Diabrotica virgifera virgifera LeConte) and northern corn rootworm (Diabrotica barberi (Smith and Lawrence)) are major pests of maize in the USA. These pests have been managed with a variety of tactics over the last century...
Investigation of genes involved in somatic embryogenesis and plant-Agrobacterium interactions through transcriptional profiling
(University of Missouri--Columbia, 2021)
giving rise to a mature whole plant. The breadth of application for genetic engineering is limited by constraints on one or both of these factors in many plant species and individual varieties. Uncovering plant genes which are involved in important...
Resource extraction, resistance, and religion in Nicaragua
(University of Missouri--Columbia, 2019)
My dissertation examines the causes of protest over resource extraction in Nicaragua, and underlines the role of religion as a catalyst for sustained and successful challenges against resource extraction. With few exceptions, existing research has...
Genetic architecture and marker-assisted breeding for salt tolerance in soybean
(University of Missouri--Columbia, 2018)
Salinity is one of the major abiotic stresses that inhibits plant growth and causes seed yield loss in soybean. Although a major gene for salt tolerance on chromosome (Chr.) 3 was mapped, cloned and characterized, it does not fully explain genetic...
