Evaluation of teosinte genetic diversity for agronomic and domestication traits in maize /
(University of Missouri--Columbia, 2017)
for adaptation and fitness related traits in the Teosinte Synthetic population. Maize plays a central role in the US agriculture and food production, as well as has the greatest molecular and phenotypic diversity than any crop species. My research study strongly...
Establishing, characterizing and deploying novel insect cell lines
(University of Missouri--Columbia, 2017)
Insect cell lines are convenient and powerful tools that were initially used in viral propagation, optimization of viral pesticides, cell-virus interactions, and recombinant protein productions. The most commonly used cell ...
Habitat manipulations to enhance the abundance and diversity of pollinators visting helianthus annuus l.
(University of Missouri--Columbia, 2016)
Insect pollinators face many challenges with the development of modern agriculture. These challenges, such as reduction in habitat range and landscape fragmentation, may be overcome by diversifying the plant community. By planting intercrops...
Mechanical and thermal weed control in organic crops
(University of Missouri--Columbia, 2017)
Effective weed control is one of the most yield-limiting factors in organic corn and soybean production. Additionally, the amount of tillage needed to control weeds in organic practice is often criticized for its negative ...
Comparison of mosquito communities collected from differing livestock locations and an examination of phenotypic traits exhibited by four latitudinally separated populations of Aedes albopictus (Skuse)
(University of Missouri--Columbia, 2013)
-Missouri agricultural locations having differing primary livestock hosts and (2) genetic differences between populations of Aedes albopictus (Skuse) collected from four differing latitudes. Adult mosquito collections from 15 trapping locations that maintained 5...
Establishment and yield of bioenergy miscanthus on clayplan soil ladscapes
(University of Missouri--Columbia, 2015)
these properties when grown on degraded, and consequently, less productive soils in traditional agricultural settings. Two independent studies were conducted over the 2013-14 growing seasons to (1) quantify how both rhizome quality and depth of soil from...
Corn physiology and yield response to hybrid and seeding rate on claypan soils
(University of Missouri--Columbia, 2015)
Yield improvements over the past few decades have been attributed to increasing optimum plant population and not the increase of grain produced per plant. A goal in precision agriculture is to identify seeding rates that optimize yield...
Effect of far-red induced shade-avoidance responses on carbon allocation in arabidopsis thaliana
(University of Missouri--Columbia, 2016)
this change in growth causes young, growing leaves to export less of the sugar they make (keeping more for themselves), but fully mature leaves did not change how much sugar they exported. Agriculture is all about getting plants to turn sunlight into products...
An environmental assessment of sensor-based variable-rate nitrogen management in corn
(University of Missouri--Columbia, 2006)
to account for spatial variability of N within agricultural fields. One approach to account for this variability and thereby reduce nitrate pollution is in-season site-specific N application according to economic optimal N rate (EONR). Recently, active...
Manganese nutrition and photosynthesis in NAD-malic enzyme C-4 plants
(University of Missouri--Columbia, 2008)
NAD-ME activity and the continued supply of CO2 to bundle sheath cells. The objective of this research was to determine the Mn requirement for optimum photosynthesis and plant biomass production for two agriculturally important NAD-ME C-4 species...
Influence of herbicides application on weed and tall fescue management and grazing distribution in Missouri pastures
(University of Missouri--Columbia, 2012)
One weed that is of concern in Missouri pastures that can be detrimental is Northern dewberry (Rubus flagellaris Willd.). This weed can be detrimental due its production of spines which can injure grazing animals and also ...
Identification and characterization of glyphosate-resistant common ragweed
(University of Missouri--Columbia, 2007)
A revolution in production agriculture has occurred over the past decade; the development and use of herbicide-resistant crops. Glyphosate is an effective, broad spectrum and offers flexible application timing with minimal crop injury...
Management alternatives for urea use in corn and wheat production
(University of Missouri--Columbia, 2006)
Traditionally, urea has been incorporated to avoid losses of N by ammonia volatilization. However, this option is not available when topdressing wheat. The objective of this project is to evaluate several strategies designed ...
Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)
Fall herbicide applications have increased in popularity in recent years. Little is known of how fall herbicide applications impact soil conditions, insect populations, and winter and summer annual weed populations. Few ...
Competition and management of volunteer corn (Zea Mays L.) in corn
(University of Missouri--Columbia, 2011)
Volunteer corn (Zea mays L.) is the result of corn kernels remaining in the field following harvest and is a competitive weed in a number of subsequent crops. With widespread adoption of glyphosate-resistant (Gly-R) corn, ...
Identification, characterization, and management of glyphosate-resistant waterhemp (Amaranthus rudis sauer.) in Missouri
(University of Missouri--Columbia, 2008)
The possibility of in waterhemp has been of concern to Midwest corn and soybean producers due to a heavy dependence on glyphosate as a weed control tool and the increased incidence and problematic nature of waterhemp in ...
Novel approaches in macroinvertebrate biomonitoring
(University of Missouri--Columbia, 2008)
The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of ...
Soil characteristics and subsequent corn development following partial corn residue removal in a no-till, corn-soybean rotation
(University of Missouri--Columbia, 2013)
If producers employ corn (Zea mays L.) residue removal for ethanol production, soil and subsequent corn development characteristics could be affected. Little research has evaluated partial corn residue removal from baling ...
The biology and ecology of tuber aestivum mycorrhizae establishment in the greenhouse and the field
(University of Missouri--Columbia, 2008)
Truffles, of the ectomycorrhizal genus tuber, are cultivated in plantations to offset declining wild production. Although methods for truffle plantation management have been published, methods for the production of ...
Effect of temperature on a soybean [Glycine max (L.) Merr.] mutant
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is influenced by temperature and light, and global warming has been shown to reduce soybean yields. In this study we tested the germination of ...
