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 humans. Results from our...
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...
Interactions between cover crops, herbicides and weeds in soybean production systems
(University of Missouri--Columbia, 2018)
. An identical field experiment was conducted in 2016 in Arkansas, Indiana, Missouri and Wisconsin and repeated in Arkansas, Indiana, Mississippi and Missouri in 2017 to evaluate the most effective herbicide treatments for spring termination of regionally...
Impact of grazing stockpiled tall fescue of lactating beef cows
(University of Missouri--Columbia, 2006)
Two experiments are described, in which fall-calving cow-calf pairs grazed stockpiled tall fescue at three different endophyte infection levels (20, 51, and 89%) and four forage allowances (2.25, 3.00, 3.75, and 4.50% of BW). A hay feeding treatment...
Impact of aphids species and barley yellow dwarf virus on soft red winter wheat
(University of Missouri--Columbia, 2005)
Barley yellow dwarf virus is one of the most widespread viral diseases of wheat. Yield reductions up to 70% have resulted from barley yellow dwarf virus (BYDV) infection. Several aphid spp. transmit BYDV. In Missouri, the four common aphids...
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)
Composition of soybean seeds is important to manufacturers of tofu and natto food products. The effect of environment on seed composition of tofu and natto soybean cultivars was measured in Missouri in 2004 and 2005. The environment was altered...
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...
The sublethal effects of ecdysone agonists on the attractiveness, responsiveness, fertility and fecundity of oriental fruit moth, a comparative examination with codling moth on larval feeding damage
(University of Missouri--Columbia, 2006)
The ecdysone agonists methoxyfenozide and tebufenozide are designed to affect the larval stage of Lepidopteran pests. Recent studies have reported sublethal effects on the adults of several tortricid apple tree pests exposed to these insect growth...
The semiaquatic heteroptera (Gerromorpha) of Thailand : faunistics, biogeography and phylogeography
(University of Missouri--Columbia, 2008)
Semiaquatic heteropterans (Gerromorpha) were collected from mountain streams and waterfalls and lowland ponds adjacent to the mountains were collected from 2002 to 2006. One hundred fifty-eight species representing 31 ...
Field pennycress management in upstate Missouri
(University of Missouri--Columbia, 2017)
increased yield in this one-year experiment. Residue and tillage management will be important in future field pennycress research. This research has identified potential seeding date, pre- and postemergence herbicide safety to field pennycress as well...
Identification and management of glyphosate-resistant annual bluegrass (Poa annua L.)
(University of Missouri--Columbia, 2010)
bluegrass (hereafter referred to as CCMO1) in Columbia, Missouri survived an application of glyphosate following more than 10 years of continuous applications. Research was conducted in vitro to identify the extent of glyphosate-resistance in CCMO1...
Soybean seed components as affected by nodal position, environmental conditions, and irrigation
(University of Missouri--Columbia, 2005)
Soybeans (Glycine max [L.] Merr.) are a major source of vegetable protein and edible oil. The nutritional quality of these seed components depends upon the relative abundance of specific proteins and fatty acids. Additionally, ...
Efficacy of organic herbicides in agronomic crops and improvement of soil biota with organic production practices
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] CHAPTER I. Literature Review. CHAPTER II. Impact of Organic Herbicides in Corn (Zea mays). Abstract: Tillage is a weed control method in organic corn production...
Resource extraction, resistance, and religion in Nicaragua
(University of Missouri--Columbia, 2019)
mining, especially related to economic threats and grievances tied to environmental and agricultural concerns, it will likely continue its resistance movement until it sees policy changes that halt or overturn mining concessions in the community. However...
Genotype, environment and GE interaction effect on soybean oil composition
(University of Missouri--Columbia, 2005)
Changing the content of the five major soy-oil fatty acids is important to enhance food, fuel and other applications of soybean oil. In addition to genetic effects, the growth environment can significantly affect oil ...
Novel approaches in macroinvertebrate biomonitoring
(University of Missouri--Columbia, 2008)
are influenced by seasonal variability. Two separate studies are presented to address aspects of biological monitoring that are seldom studied. The first study focused on evaluation of Grass Riparian Filter Strip effectiveness in north central Missouri. Streams...
Characterization of berry and wine aroma development in interspecific hybrids important to Missouri using a metabolomics based approach
(University of Missouri--Columbia, 2020)
the aroma profile of two hybrid grapes Norton and Chambourcin, important to the Mid-Western United states, including Missouri, along with the differences during berry development. We also investigated the change in aroma profile of Chambourcin berries due...
