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 ...
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 ...
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 ...
An environmental assessment of sensor-based variable-rate nitrogen management in corn
(University of Missouri--Columbia, 2006)
Nitrogen (N) fertilizer unused by the crop is left to the fate of the processes of the N cycle, and can eventually lead to nitrate contamination of surface and ground waters. In order to address this problem, various methods ...
Reaction of soybean cultivars to waterlogged soil
(University of Missouri--Columbia, 2006)
Irrigating soybean prior to an extensive rain can result in waterlogged soil that may cause root damage and plant death. Some soybean cultivars tolerate waterlogged soils. The objective of this study was to evaluate tolerance ...
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 ...
Function of abscisic acid in maintenance of maize primary root growth under water deficit
(University of Missouri--Columbia, 2006)
Previous studies suggested that ABA accumulation is required to maintain maize primary root elongation under water deficit and that one of the functions of ABA is to restrict ethylene evolution. These studies were conducted ...
Biodiversity of ants (Hymenoptera: Formicidae) in restored grasslands of different ages
(University of Missouri--Columbia, 2006)
Grasslands are an endangered ecosystem. Unfortunately, few studies monitoring the health of these grasslands have included arthropods, thus leaving out a vital biodiversity component. Ants have been proven to be reliable ...
Molecular cloning and characterization of regulatory enzymes in threonine biosynthetic pathway from soybean
(University of Missouri--Columbia, 2007)
Soybeans (Glycine max [L.] Merr.) are a good source of protein and oil. Despite being a very good source of protein, soybeans nutritional value is limited by low proportion of sulfur amino acids methionine and cysteine ...
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)
Subterranean termite species in the genus Reticulitermes are ecologically and economically important in the United States. At least six species of the genus Reticulitermes are native from North American forests where they ...
Phosphorus nutrition in tall fescue : from stockpiling to seed production
(University of Missouri--Columbia, 2007)
Tall fescue (Festuca arundinacea) is the most important forage for beef production in the Midwest. Stockpiling tall fescue allows producers to extend the grazing season and reduce winter-feeding costs. In Missouri, forages ...
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 ...
Molecular diagnostics of economically important Wireworm species (Coleoptera: Elateridae) in midwestern United States
(University of Missouri--Columbia, 2007)
Wireworms are a common soil-dwelling pest of corn (Zea mays L.) in the Midwestern United States. Wireworms are a problematic group to control and study due to the difficulty involved in identification. The objectives of ...
Physiological traits underlying differences in salt tolerance among glycine species
(University of Missouri--Columbia, 2008)
Salinity drastically reduces crop yield by limiting water uptake and causing ion-specific stress. Soybean is sensitive to soil salinity. Previous studies, however, have shown that there is variability among soybean genotypes ...
The sublethal effects of methoxyfenozide on the field orientation and courtship behavior of Cydia pomonella (Linnaeus) (Lepidoptera: tortricidae)
(University of Missouri--Columbia, 2008)
The sublethal effects of ecdysone agonist methoxyfenozide on the mating behavior and field orientation of codling moth, Cydia pomonella (Linnaeus), was examined. Five different lure types were placed in the upper canopy ...
Plasticity of soybean (Glycine max (l.) Merrill) root system development under mild water deficit
(University of Missouri--Columbia, 2008)
Drought is the major abiotic factor limiting soybean yield in the US. Under water deficit conditions, root systems may exhibit developmental plasticity resulting in morphological changes that extend the water-absorbing ...
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 ...
Study of anti-cancer effect of winter worm and summer grass on Mcf-7 human breast cancer cells
(University of Missouri--Columbia, 2008)
Winter worm and summer grass (WWSG) is one of the most valued traditional Chinese medicines for fighting cancer, increasing longevity, and improving immunity. It consists of the entomopathogenic fungus Cordyceps sinensis ...
Interplanting of a deficient soybean stand
(University of Missouri--Columbia, 2008)
The planting of adequate soybean seeds does not always materialize into a satisfactory final plant stand. Many different environmental factors play an important part in the process of soybean germination and emergence. ...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
