Overseeding annual ryegrass and cereal rye into soybean for winter forage and as a cover crop for weed control and soil conservation
(University of Missouri--Columbia, 2005)
was grown as a subsequent crop. Soybean yield was not altered by overseeding annual ryegrass or cereal rye. All treatments yielded over 2,500 kg ha-1 for the season (with a high of 4,200 kg ha-1), which would supply much needed pasture for winter grazing...
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...
Cover crop and rotation intensity effects on soil health and yield in corn-soybean cropping systems
(University of Missouri--Columbia, 2020)
soil health and cash crop yields for the long-term. The implementation of cover crops and crop rotation are widely promoted management strategies that have been shown to enhance soil health in agricultural systems, and may lead to increases in cash crop...
Competition and management of volunteer corn (Zea Mays L.) in corn
(University of Missouri--Columbia, 2011)
(10, 20, and 40 cm) in glufosinate-resistant or imidazolinone-tolerant hybrids, respectively. Research was conducted during 2008, 2009, and 2010 at multiple locations throughout central and northeast Missouri. Harvest inefficiencies resulted in kernels...
Mechanical and thermal weed control in organic crops
(University of Missouri--Columbia, 2017)
. This research was conducted in central Missouri from 2016-2017 to compare cultivation, flame application, between-row mowing, and hot water spray for in-season weed control in organic corn and soybeans. Between-row mowing and hot water application were paired...
Detection of phythium spp. in gold course irrigation systems
(University of Missouri--Columbia, 2020)
Many Pythium spp. are causal agents of disease on creeping bentgrass putting greens. Phytopathogenic Pythium spp. are known to disseminate through irrigation systems in agricultural settings, and this study provides evidence that Pythium spp. also...
Biology and management of cut-leaved Teasel (Dipsacus laciniatus L.) in central Missouri
(University of Missouri--Columbia, 2006)
Cut-leaved teasel is a biennial invasive weed that grows along roadsides and low disturbed areas. This research was to determine growth characteristics, herbicide efficacy, and seed production of teasel. Growth characteristics ...
Poison hemlock (conium Maculatum L.) : biology, implications for pastures and response to herbicides
(University of Missouri--Columbia, 2008)
Poison hemlock is a biennial, toxic and invasive weed that grows along roadsides, pastures and low-disturbed areas. Research was conducted to determine seed ecology, growth characteristics and response to herbicides. Seed ...
Effect of irrigation on fertilizer nitrogen requirement, economic returns, and water availability in a corn-soybean rotation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In regions of the US and the world where precipitation does not consistently meet crop water needs, there is extensive research documenting the value of irrigation to increased...
Reducing ergovaline and ergot alkaloid concentrations through fertilizer, herbicide and clipping management
(University of Missouri--Columbia, 2010)
rather than chemical NPK reduced ergovaline by at least 124 [mu] kg-1 DM. Another experiment showed the herbicide clethodim reduced ergovaline up to 72%. A third experiment, conducted with Clemson University and the University of Georgia, showed...
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 teasel management along a...
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)
. In urban environments they feed upon dead wood, and therefore infest and destroy man-made wooden structures. Missouri is considered to have a moderate risk for termite infestations when compared with the states of the southeast part of the country. Despite...
Field pennycress management in upstate Missouri
(University of Missouri--Columbia, 2017)
Field pennycress has the potential to serve as a cover and oilseed crop. A seed oil content of 25 to 36 percent has created interest in pennycress domestication. This research evaluated management strategies for growing ...
Investigation of genes involved in somatic embryogenesis and plant-Agrobacterium interactions through transcriptional profiling
(University of Missouri--Columbia, 2021)
Plant genetic engineering relies on the ability to transmit and express cloned DNA sequences in plant cells (transformation) as well as the capacity for the cells carrying this DNA to undergo division and differentiation ...
Soybean resistance and yield response to southern root-knot nematode
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean represents the largest and most concentrated segment of global agricultural trade. Despite its consistent yearly yield increment around the world, biotic stresses can...
Response of beef cattle selected for tolerance to tall fescue toxicosis
(University of Missouri--Columbia, 2019)
Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) infected with the endophytic fungus, Epichlooجا coenophiala [(Morgan-Jones & W. Gams) C.W. Bacon & Schardl, comb. nov.] produces ergot alkaloids that result in a ...
Biodiversity of ants (Hymenoptera: Formicidae) in restored grasslands of different ages
(University of Missouri--Columbia, 2006)
sampling) on four different ages (0, 3, 7-8, 14-16 yrs) of grassland in east-central Missouri. Efficacy of sampling methods was also examined. A total of 18,743 ants were collected, representing 28 species in 16 genera. Ants were most abundant in older ages...
High throughput profiling of transcription factors involved in soybean root growth under water deficit
