Career development events as a predictor of fall-to-fall retention of first-year college students
(University of Missouri--Columbia, 2020)
examined whether participation and performance in agricultural education CDEs in high school can predict retention of first-year, first-time, full-time college students enrolled in agricultural sciences at a regional, Midwest, public university...
Roadway effects on the hydrologic regime of temporary wetlands in the Missouri River floodplain in Missouri
(University of Missouri--Columbia, 2005)
on the hydrologic regime of temporary wetland basins within the agricultural landscape of the Missouri River floodplain from Hartsburg to Independence, Missouri. This study is part of a larger existing research project designed by the Missouri Department...
Effect of irrigation on fertilizer nitrogen requirement, economic returns, and water availability in a corn-soybean rotation
(University of Missouri--Columbia, 2019)
application. Two irrigation experiments were conducted at University of Missouri Greenley Research Center near Novelty, MO from 2015 to 2018. In each experiment, three irrigation treatments: sprinkler irrigation, subsurface drip irrigation, and no...
Three essays on food security, agricultural productivity, and commodity basis
(University of Missouri--Columbia, 2021)
The proposed research is constructed around the theme of food security, agricultural productivity, and commodity basis. The first paper analyzes the impacts of COVID-19 on the Bangladesh rice market within the framework of a partial equilibrium...
The relation of the size of seed to the character of plant produced
(University of Missouri--Columbia, 1916)
Text taken from pages 1 and 2 of this thesis: During the past fifty years a number of investigators have reported results on the relative value of heavy and light or large and small seed grain. Each investigator has devised a some what different...
Factors influencing use of split-lines of credit and internal capital rationing among PCA borrowers
(University of Missouri--Columbia, 1984)
Farmers’ use of credit has been studied extensively because debt capital is an integral part of present-day agricultural financial management. However, very little is known about split-lines of credit or multiple sources of credit financing...
A Study of the effect of liming an acid soil on the growth of certain legumes and non-legumes
(University of Missouri--Columbia, 1914)
have been heavy or applied immediately before the growth of plants. P.E. Karraker at this Station observed a depressing effect of ground limestone on the growth of certain legumes. It was purposed in the experiments herin reported to continue the work...
Development of implementation methods of water quality trading policy : using the Hydrological simulation program-Fortran (HSPF)
(University of Missouri--Columbia, 2010)
-fortran (HSPF) was used to estimate the hydrology and sediment loading throughout the Brush Creek, MO watershed for future land use development scenarios between upstream and downstream locations. Brush Creek does not have a proper monitoring station...
Electromagnetic effects on soybeans
(University of Missouri--Columbia, 2007)
on Magellan for repeat experiments were inconclusive at best. Germination for case studies with two hundred samples showed marked improvement but the statistical significance for much larger sample (1000 seeds) decreased. All the experiments were conducted...
Investor capital, taxes and the structure of cattle feeding
(University of Missouri--Columbia, 1974)
of cattle feeding are a relatively minor part of the total capital invested in agriculture. However, new forms of cattle feeding financing makes the investment increasingly attractive to nonagricultural investors. Large size cattle feeding firms, formed...
Estimation of total height, growth, and mortality of forest trees in Missouri
(University of Missouri--Columbia, 2005)
A model for predicting total tree height as a function of tree diameter was calibrated for twelve tree species common to the Missouri Ozarks. Model coefficients were derived from nearly 10,000 observed trees. The calibrated model did a good job...
The effect of age and condition on the mineral composition of the ash of the bovine
(University of Missouri--Columbia, 1916)
and in most cases incomplete. Furthermore, a great deal of the data as presented by various investigators cannot be compared because of lack of uniformity in reporting results as well as in the selection of samples for analysis. Forbes in his bulletin on "The...
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...
A multi-configuration evaluation of the soil and water assessment tool (SWAT) in a mixed land use watershed in the central U.S.A.
(University of Missouri--Columbia, 2011)
. Watershed and soil resolution had negligible impact; climate input had considerable impact. Single climate station input is best used for applications requiring monthly predictions; distributed climate station input is needed for daily predictions. SWAT...
A multi-scale investigation of ecologically relevant effects of agricultural runoff on amphibians
(University of Missouri--Columbia, 2008)
Modification of landscapes for agricultural production can introduce agrochemicals into surface waters and degrade aquatic habitats used by many amphibians for breeding and larval development. Although many ecotoxicological studies have shown...
A study of the factors influencing the ability of the animal to digest its food
(University of Missouri--Columbia, 1916)
The purpose of the digestion trials, to be discussed in this paper, was to determine the effect of various factors on the ability of the animal to digest its food. The object of these experiments is somewhat different from the great majority...
Quantifying suspended sediment loading in a mid-Missouri urban watershed using laser particle diffraction
(University of Missouri--Columbia, 2011)
/water-quality stations were installed in a nested-scale watershed study design to capture differing land-use type influences on SSC. Mean SSCs were estimated to be 66.0, 70.0, and 86.0 [mu]l/l for the headwater (agricultural), suburban (mixed land-use), and urban sub...
Climate and land use effects on hydrologic processes and water allocation in a primarily rain-fed, agricultural watershed
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] There is a need to raise our understanding of the impact of climate variability and change on hydrologic processes at the watershed scale. This is important, particularly...
Alternative tillage and nitrogen management options to increase crop production and reduce nitrous oxide emissions from claypan soils
(University of Missouri--Columbia, 2010)
The Central Claypan Region covers an area of 10 million acres of claypan or claypan-like soil in Missouri, Oklahoma, Kansas, Iowa, and Illinois. Agricultural production on claypan soil can have lower yield and a greater impact on the environment...
