Allelopathic effects and removal of overseeded ryegrass on bermudagrass
(University of Missouri--Columbia, 2010)
Allelopathy is a complex phenomenon among plants that involves the production of defensive chemicals that influence the growth and survival of adjacent plants. Plants like perennial ryegrass become suspect when bermudagrass ...
Herbicide resistant weeds in Missouri : sources and solutions
(University of Missouri--Columbia, 2019)
Herbicide resistant weeds continue to invade new territories each year. Two studies were designed to identify both the spread and the current status of herbicide resistant weeds in Missouri. In 2016 and 2017, 98 separate ...
Viability, vigor, and field performance of a low phytic acid, high phytase activity soybean line, CAPPA
(University of Missouri--Columbia, 2009)
Plants store inorganic phosphate (Pi) in seeds as phytic acid (PA). Phytic acid chelates essential macro and micronutrients in developing seeds forming phytate, which is nutritionally unavailable to monogastric livestock. ...
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 ...
A preliminary list of the rusts of Boone County
(University of Missouri--Columbia, 1913)
A complete list of the rusts of Boone County has not been published. In the year 1889 Dr. B.T. Galloway of the U. S. Department of Agriculture, published a preliminary list of the parasitic fungi of Missouri. The specimens ...
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 ...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
, delivered as a spray solution (36 or 72 ppm) or by vapor from treated soil. The severity of dicamba injury (leaf cupping and feathering) was similar at 2 of 3 site years, with greater injury related to particle versus vapor drift of dicamba. Across all site...
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 ...
Integrated management of the invasive weed, cut-leaved teasel (Dipsacus laciniatus L.) along a Missouri highways
(University of Missouri--Columbia, 2008)
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 ...
Cover crop and rotation intensity effects on soil health and yield in corn-soybean cropping systems
(University of Missouri--Columbia, 2020)
stable aggregates, soil moisture, total organic carbon, active carbon, potentially mineralizable nitrogen (PMN), and soil microbial community composition via a phospholipid fatty acid (PLFA) analysis were measured in 2017 and 2018 in Columbia, MO under no...
Characterization of raffinose synthase genes in soybean
(University of Missouri--Columbia, 2009)
As the use of soy products in foods and feeds increases, it is ever more important to consider the nutritional value of each component of the seed. The carbohydrate component is largely composed of sucrose, raffinose, and ...
The effect of environment on seed composition of tofu and natto soybean cultivars
(University of Missouri--Columbia, 2006)
in Missouri also affected seed composition. Sucrose was highest at the Columbia location and stachyose was lowest at Oran for both years. Sucrose was negatively correlated to August temperatures in 2004 and 2005. These results can aid in producing management...
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 ...
Modification of fatty acid composition in soybean seeds to improve soybean oil quality and functionality
(University of Missouri--Columbia, 2011)
acid content. Combination of two mutant FAD2-1A and FAD2-1B with mutant FAD3A or mutant FAD3C or both resulted in high oleic acid content of 80 - 85% and linolenic acid content in the range from 1.5 - 4%. Perfect molecular markers associated...
The underlying genetic control of maize root system architecture
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Maize (Zea mays ssp. mays) is one of the most widely cultivated and highest yielding grain crops in the world. The genetic and phenotypic diversity ...
Reducing ergovaline and ergot alkaloid concentrations through fertilizer, herbicide and clipping management
(University of Missouri--Columbia, 2010)
Animals grazing tall fescue grass (Lolium arundinaceum) infected with Neotyphodium coenophialum consume the toxins ergovaline and other ergot alkaloids. This research included a series of experiments with two overall objectives: 1) to explore...
Predator-prey interactions involving the soybean aphid (Hemiptera: Aphididae) in Missouri
(University of Missouri--Columbia, 2007)
The recently introduced soybean aphid, Aphis glycines Matsumura, is found in all soybean growing areas within Missouri. Despite soybean aphid's widespread distribution, it has reached economic threshold in few soybean ...
Environmental and human impacts on off-target movement of dicamba
(University of Missouri--Columbia, 2020)
growth was reduced 10 to 54% and visual injury ranged from 15 to 47% at 21 DAT. Average soybean yield was significantly reduced by dicamba concentrations as low as 25 ppm and influenced by the developmental stage (V3 and R1) at the timing of dicamba...
