Influence of characters of ear and kernel upon the germination of maize
(University of Missouri--Columbia, 1912)
of the ear and kernel which have a marked influence upon the yield. This is so universal that we have score cards which set forth the ideal type of ear and give certain values to the different characters. In general, the score cards are alike and all agree...
Power in the garden : exploring the lives of Missouri farm women and their vegetable gardens during the Great Depression
(University of Missouri--Columbia, 2007)
Today, when fresh, canned, and frozen vegetables are plentiful and taken for granted, the home vegetable garden is regarded as something between a hobby and a luxury. But in the Great Depression of the 1930s, the household ...
Irrigation practices and costs in southeastern Missouri - 1959
(University of Missouri--Columbia, 1961)
Field crop irrigation is a relatively new production technique in Missouri. Prior to this investigation, only United information was available concerning costs and returns. The research reported here was assigned to determine (1) the costs...
The effect of calcium carbonate of certain soil constituents and on plant growth
(University of Missouri--Columbia, 1915)
of Problem": It is the purpose of this investigation to secure data on the effects of adding calcium carbonate in the form of ground limestone to types of soils of common occurrence in the state of Missouri. These effects were studied in crop yields, in per...
Occupancy modeling of forest carnivores in Missouri
(University of Missouri--Columbia, 2008)
My research used infrared remote cameras, trackplate boxes, and scat transects to survey for carnivores at 53 sites throughout the southern forested region of Missouri. Cameras and track-plates both detected Eastern spotted skunk (Spilogale putorius...
Winter rations for dairy heifers
(University of Missouri--Columbia, 1917)
The special object of these experiments is to compare the efficiency and economy of rations which are conducive to rapid growth with rations of such character as to admit of but limited growth....
Forging a national diet : beef and the political economy of plenty in postwar America
(University of Missouri--Columbia, 2018)
Few foods items are more associated with the United States than beef yet it was not until the 1950s that Americans ate more beef than any other meat. The triumph of mass beef consumption was not accidental or a preordained ...
Factors favoring or opposing injuries from transplanting
(University of Missouri--Columbia, 1918)
"The purpose of this investigation was to determine the factors favoring or opposing the injuries following the transplanting of vegetables. The factors dealt with in this study were as follows: (a) The relation of moisture ...
Intraguild interactions between native and domestic carnivores in central India
(University of Missouri--Columbia, 2008)
Bustard Sanctuary, Maharashtra, India and assessed resource selection based on landcover characteristics. Indian foxes chose for grassland habitats at the scale of both landscape and home-range level and avoided human-dominated areas such as agricultural...
The effect of different nutritive planes upon the economy of gain and the rate of growth of young cattle
(University of Missouri--Columbia, 1909)
This investigation was undertaken in order that something might be learned concerning: (a) the cost of maintenance of live weight in ungrown cattle; (b) the effect of a maintenance ration upon the condition of ungrown ...
Quantifying riparian canopy energy attenuation and stream temperature using an energy balance approach
(University of Missouri--Columbia, 2011)
of the central U.S. Hydroclimate data were collected from two intensively instrumented stream reaches of opposite orthogonal compass orientation in a semi-karst watershed on the border of southern Missouri's Ozark region, USA, during the 2010 water year. Data...
Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)
compared fall herbicide applications to early spring applications. Therefore, field experiments were conducted in both no-till corn and soybean fields from 2004 through 2006 in central, northwest, and northeast Missouri. Herbicide applications were made...
Delineation of critical management areas at plot, field, and watershed scales for claypan soils
(University of Missouri--Columbia, 2010)
and water quality and given rise to non-point source pollutants. The claypan soil region of Missouri has a high runoff potential that increases the possibility of transport of non-point source pollutants to downstream sites. The Agricultural Policy...
The potential of producing bioenergy crops on conservation reserve program land in Missouri, Iowa, Nebraska, and Kansas (MINK Region) to mitigate carbon dioxide emissions : an integrated economics and biological modeling approach
(University of Missouri--Columbia, 2010)
policymakers develop sustainable and balance of energy-agriculture-environmental policies....
Winter bird densities and eastern wood-pewee breeding demography across a savanna-woodland-forest gradient in the Missouri Ozarks
(University of Missouri--Columbia, 2012)
and woodland is needed to inform management. Our objective was to determine densities of common winter migrants and resident birds in savannas, woodlands, and non-managed forests in the Missouri Ozark Highlands. We estimated detection probabilities...
The killing of plant tissue by low temperature
(University of Missouri--Columbia, 1914)
-soaked appearance, and evaporation from that tissue is much more rapid than from living tissue. In the experiments described in this paper, the killing temperature of plant tissue that kills at relatively high temperature has been reduced whenever the sap density...
Imidacloprid sorption and transport in cropland, grass buffer and riparian buffer soils
(University of Missouri--Columbia, 2016)
sorption and column leaching experiments were performed using soils collected from cropland (crop), grass vegetative buffer strips (VBS), and riparian VBS. Single-point, solid-to-solution partition coefficients (Kd) were determined by reacting soil...
Evaluating effects of neonicotinoid seed treatments and agroecosystem land management practices on solitary bees in Midwestern agroecosystems
(University of Missouri--Columbia, 2021)
Bees are declining due to multiple factors including habitat loss and non-target exposure to pesticides resulting from agricultural intensification. Solitary bees are often overlooked as important pollinators, but they are valuable contributors...
Sustainable management of invasive species
(University of Missouri--Columbia, 2023)
invasions. The main objectives of this dissertation were to: 1) evaluate the efficacy of an attract-and-kill strategy targeting Japanese beetle, 2) quantify how attract-and-kill impacts arthropod short- distance dispersal in an agricultural setting, and 3...
Wildlife response to spatial and temporal changes in forest habitat
(University of Missouri--Columbia, 2008)
A common goal in land-management planning is to describe the relationship between management actions, vegetation and wildlife habitat conditions for large landscapes. Achieving this goal can be challenging because ecological ...
