Morphological And Genetic Analysis Of The Root System In Two American Grapevines (Vitis Species), Parinaz Mohtasebi
Morphological And Genetic Analysis Of The Root System In Two American Grapevines (Vitis Species), Parinaz Mohtasebi
MSU Graduate Theses
The North American grapes species Vitis rupestris Scheele and Vitis riparia Michx have been the pillars of rootstock breeding for many decades. Though a large body of viticultural knowledge has been accumulated on their impact on grafted scions, the genetic basis of their root system architecture (RSA) has received limited scientific attention. In this study, I generated and analyzed adventitious root systems from dormant cuttings of 22 V. riparia and 19 V. rupestris accessions, as well as 162 interspecific F1 hybrid progeny from a cross between V. rupestris (♀) and V. riparia (♂). I photographed the roots and then extracted …
Intercropping Grain Sorghum Into Established Rhizoma Peanut: Greenhouse And Field Studies, Erika Hm Cooperman
Intercropping Grain Sorghum Into Established Rhizoma Peanut: Greenhouse And Field Studies, Erika Hm Cooperman
MSU Graduate Theses
Land degradation and urbanization are among the top factors pushing the Kenyan Maasai community into an unstable future, with food insecurity and poverty amidst the most fragile components. Implementing conservation agricultural techniques into the Maasai nomadic lifestyle could potentially lead to a diversification of finances and food security. Intercropping is one technique of conservation agriculture that could provide the Maasai both. The main objective of this study is to evaluate the effects of creating an intercropped environment between rhizoma peanut and grain sorghum. A greenhouse study was conducted from late 2020 to 2021 in an effort to investigate the effects …
Establishing Regenerative Pasture Systems Using Management Intensive Grazing In The Ozarks, Shelbi M. Mundy
Establishing Regenerative Pasture Systems Using Management Intensive Grazing In The Ozarks, Shelbi M. Mundy
MSU Graduate Theses
Soil carbon and soil health are important topics relating to how climate change is impacting agriculture, and how agriculture can in turn impact climate change. The agriculture industry, particularly beef production, has a large opportunity to use conservation agriculture techniques, such as rotational grazing, to offset some of the industry’s impact on carbon emissions, erosion, water pollution, and other environmental issues. This study is the beginning of a long-term project exploring regenerative pasture systems in the Ozarks. The project takes place in a rotational grazing system with 12 paddocks. The objectives of this study are to characterize soil types by …
The Effects Of Titanium Dioxide Nanoparticles On The Growth And Development Of Sorghum Bicolor (L.) Moenech, Adam Gregory Shoemaker
The Effects Of Titanium Dioxide Nanoparticles On The Growth And Development Of Sorghum Bicolor (L.) Moenech, Adam Gregory Shoemaker
MSU Graduate Theses
Engineered nanoparticles (ENPs) have seen a drastic increase in their use over the past decade in various consumer products. ENPs will therefore enter terrestrial ecosystems and soils with increasing frequencies, yet research into the effects of ENPs on living organisms and crops is greatly lacking. Currently, there is only one major study reported on the effects of a single ENP, silver quantum dots, on Sorghum bicolor, the 5th largest crop in the world. I examined the effects of a commonly used metal oxide nanoparticle, titanium dioxide (TiO2), on the growth and development of sorghum grown in …
Macronutrient Content Of Winter Annual Cereal Grains With Phosphorus Fertilization, Taylor Anne Young
Macronutrient Content Of Winter Annual Cereal Grains With Phosphorus Fertilization, Taylor Anne Young
MSU Graduate Theses
Missouri ranks third in the United States in cow-calf production, and much of the land these cattle graze has acidic soil that is low in plant available phosphorus (P). Proper soil fertility is important to ensure that these forages meet the nutritional requirements of cattle. Tall fescue (Festuca arundinaceum (Schreb.)), has been shown to respond to increased soil P levels with increased growth and leaf concentrations of P, calcium (Ca), magnesium (Mg), and potassium (K). It is unknown if winter annual cereals will respond similarly. The objective of this study is to examine cereal rye (Secale cereal L.), winter wheat …
Relative Contribution Of Physical Interference And Allelopathy To Weed Suppression By Winter Annual Cover Crop Mixtures, Alyssa D. Travlos
Relative Contribution Of Physical Interference And Allelopathy To Weed Suppression By Winter Annual Cover Crop Mixtures, Alyssa D. Travlos
MSU Graduate Theses
Cover cropping systems are widely used in crop production systems to prevent erosion, improve soil health, and suppress weeds. Common cover cropping systems include combinations of cereal rye (Secale cereale L.), Brassica species, legumes, and other winter annual species. Three cover crop mixtures (cereal rye alone, cereal rye plus winter pea, and cereal rye plus winter pea plus radish) were applied using three methods (fresh residue, dried leached residue, and leachate) to common waterhemp (Amaranthus tuberculatus var. rudis) and large crabgrass [Digitaria sanguinalis (L.) Scop.]. The experiment was conducted once in a greenhouse and once in a …
Impacts Of Cover Crop Mixtures On Productivity Of Cropping Systems, Brionna Lee West
Impacts Of Cover Crop Mixtures On Productivity Of Cropping Systems, Brionna Lee West
MSU Graduate Theses
A field study and a meta-analysis were conducted to compare the impact of cover crops on carbon and nitrogen dynamics and cash crop yield. The field study included six treatments: winter cereal rye, winter cereal rye-Austrian winter pea at two seeding rates, cereal rye-Austrian winter pea-radish at two seeding rates, and a no cover control. Meta-analysis data sets were compiled from studies published between 1994 and 2017. Treatments were grouped into the following classifications: monoculture, binary mix, polyculture, or control. In both the field study and meta-analysis, cover crops did not affect cash crop yield. However, plant biomass and plant …
Effects Of Irrigation On Forage Growth Rates On Rotational Grazing Dairies, Zachary Davis
Effects Of Irrigation On Forage Growth Rates On Rotational Grazing Dairies, Zachary Davis
MSU Graduate Theses
The amount and timing of rainfall in Missouri can be very irregular. This causes issues for producers of agronomic products in the state who rely on forages for income. The most sensible approach to the problem is the use of irrigation. But there is little useful information to reference when implementing this management decision. By studying three different styles of irrigation (center pivot, spider, and k-line) on 4 species of forages native to Missouri (alfalfa, crabgrass, perennial ryegrass, and tall fescue/clover), this study provides valuable insight as to the cost and benefit of irrigation. The main goal is to produce …
Alternative Feeding Strategies For Growing Cattle Grazing Endophyte-Infected Tall Fescue During The Summer, Kerri A. Johnson
Alternative Feeding Strategies For Growing Cattle Grazing Endophyte-Infected Tall Fescue During The Summer, Kerri A. Johnson
MSU Graduate Theses
Two experiments were conducted to determine animal performance of alternative feeding strategies to heifers grazing endophyte-infected tall fescue during summer months. In Experiment 1, 40 Limousin heifers (261± 40kg initial BW) were stratified by weight and assigned to either a spring harvested tall fescue silage diet or grazing endophyte-infected tall fescue pasture with grain supplement having either natural or artificial shade for 80 days. In Experiment 2, 40 Limousin heifers (277 ± 44kg initial BW) were stratified by weight and assigned to either a traditional grain supplement or feather-meal supplement (rumen bypass arginine supplement) with natural or artificial shade while …
Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler
Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler
MSU Graduate Theses
Invasive woody plants and trees can have a negative impact on desired tree regeneration in the understory of forest stands, and forage density in grassland sites. An assessment of chemical and mechanical treatments on woody plants in the understory of forestland and in grassland is needed. Two experiments were set up in two forest stands and in two grassland/forest edge sites, with two treatment times during the growing season in the first year of the study. On the forestland sites, chemical and mechanical treatments were applied on undesired woody plants to see if they effect the regeneration of desired tree …
