Transpiration-Use Efficiency Coefficient Of Seven Weed Species As Affected By Fraction Of Transpirable Soil Water And Growth Stage, Venkatarao Mannam

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Transpiration-use efficiency coefficient (Kc) describes the amount of biomass produced per unit transpiration at a given vapor pressure deficit. A series of greenhouse experiments were conducted to determine the K_c values of seven weed species and to measure how K_c values were affected by fraction of transpirable soil water (FTSW) level and plant growth stage. Experiments were conducted using a factorial design with 4 levels of water stress (0.3, 0.4, 0.7, and 1.0 FTSW) and two harvest times (first bloom and seed maturity). After plants attained a predetermined size, each plant was sealed at the base using a …

Summer Squash, Brianne Sherwood, Elizabeth Inman

USU Student Organic Farm Newsletter

Summer squash is a soft-shelled vegetable with a whiter meat inside. It is fairly common and easy to grow about anywhere as long as there is a warm season. There are over twenty varieties of summer squash. This year on the farm we have crookneck squash (the light yellow squash with a curved neck), magna squash (the wide green one with light green stripes), yellow zucchini, and green zucchini. Summer squash is actually picked when it is still immature. Because of this the outer skin can be eaten unlike some other types of squash. It is best when smaller as …

Do Wind Turbines Affect Weather Conditions?: A Case Study In Indiana, Meghan F. Henschen, Brittany Herrholtz, Lacey Rhudy, Kathryn Demchak, Brian Doogs, Joshua Holland, Erik Larson, Johnny Martin, Matthew Rudkin

The Journal of Purdue Undergraduate Research

Wind turbines are becoming increasingly widespread in the United States as the world looks for cleaner sources of energy. Scientists, policymakers, and citizens have strong opinions regarding the positive and negative effects of wind energy projects, and there is a great deal of misinformation about wind energy circulating on the Web and other media sources. The purpose of this study is to gain a better understanding of how the rotation of hundreds of turbines can influence local weather conditions within a wind farm and in the surrounding areas. This experiment measures temperature, atmospheric pressure, wind speed, wind direction, relative humidity, …

Beets, Brianne Sherwood

USU Student Organic Farm Newsletter

The beet is such a unique vegetable. They are packed full of nutrients, including folate, manganese, potassium, vitamin C, copper, magnesium, iron, phosphorus, and fiber. Besides all these vitamins and minerals, beets are full of betalains, which act as potent cancer fighters. Betalains are also what gives beets their intense purple color.

Kohlrabi, Brianne Sherwood

USU Student Organic Farm Newsletter

Kohlrabi may look like it's from another planet with the weird stems coming out of it's bulb and the unique flavor, but it's actually really, really tasty. Honestly, it's one of my personal favorites from the entire garden. Although kohlrabi is very popular in Eastern Europe, it's not very popular in the Western world YET, but will most likely gain popularity. It's being seen in more and more farmer's markets across the country. I would say the flavor is more of a mix between broccoli and cabbage with the texture of a radish. So really, it's like eating three vegetables …

Evaluation Of Vacuum Packaging On The Physical Properties, Solubility, And Storage Space Of Dairy Powders, Hadi Eshpari

Master's Theses

As many of the dairy powders manufactured have to travel long distances to reach their customers, both domestically and internationally, there is considerable interest among dairy powder manufacturers to maintain the quality of their products for relatively long storage periods. Dairy powders can have a long shelf life if packaged and stored properly. Vacuum packaging can be an attractive packaging strategy to maintain the quality of dairy powders and provide added value by improving the efficiency of using the storage space; because of the inherent compactness of these products. Vacuum packaged dry dairy ingredients may also have added ease of …

Identifying Changes In Climatic Trends And The Fingerprints Of Landuse And Landcover Changes In The High Plains Of The Usa, Denis Mutiibwa

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Human activities such as conversion of natural ecosystem to croplands and urban-centers, deforestation and afforestation impact biophysical properties of land surface such as albedo, energy balance, and surface roughness. Alterations in these properties affect the heat and moisture exchanges between the land surface and atmospheric boundary layer. The objectives of this research were; (i) to quantitatively identify the High plains’ regional climate change in temperatures over the period 1895 to 2006, (ii) detect the signatures of anthropogenic forcing of LULC changes on the regional climate change of the High Plains, and (iii) examine the trends in evolving regional latent heat …

Herbicide-Resistant Risk Assessment: Response Of Common Nebraska Weeds To Dicamba Dose, Roberto J. Crespo

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Dicamba-resistant soybeans are being developed to provide an additional herbicide mechanism of action that can be used in soybean, and to provide a tool to help manage or mitigate the evolution of other herbicide-resistant weed populations. The objectives of this thesis were to assess the risk of common Nebraska weeds developing resistance to dicamba, quantify baseline dose-response to dicamba of high-risk weed species, and survey the variability in dicamba dose-response among populations of those species. Twenty-five weed scientists were asked to estimate the risk likelihood of ten weed species evolving resistance to dicamba following the commercialization of dicamba-resistant soybean. Palmer …

Biofilter Media Characterization Using Water Sorption Isotherms, Guilherme Del Nero Maia, George B. Day, Richard S. Gates, Joseph L. Taraba

Biosystems and Agricultural Engineering Faculty Publications

Compost material has been used extensively as a gas‐phase biofilter media for contaminant gas treatment in recent years. One of the biggest challenges in the use of this type of material is adequate control of compost moisture content and understanding its effect on the biofiltration process. The present work provides a methodology for characterization of biofilter media under low moisture conditions. Results indicated that low levels of equilibrium moisture content (EMC) were obtained for high levels of equilibrium relative humidity (ERH), i.e., 99% ERH produced EMC of approximately 20% (dry basis) at 25° C. Most bacteria struggle to survive in …

Comparison Of Soil Chemistry And Microbial Communities That Inhabit The Rhizosphere Of Native And Non-Native Grasses Of The Lower Rio Grande Valley, Jacqueline Valencia

Theses and Dissertations - UTB/UTPA

Non-native grasses can modify the soils they invade. This study investigated microbial variation among native and non-native grasses in the Lower Rio Grande Valley. We hypothesized that rhizospheres of non-native grasses would support a higher density of microorganisms; therefore microbial communities of invasive plants would exploit more carbon sources than those of native plants. A second hypothesis stated that Streptomyces bacteria from the rhizosphere of non-native grasses would be better competitors. Samples of grasses, and soil from their respective rhizospheres were obtained in Arroyo City, TX. Results indicated a higher bacterial colony density, total activity and number of substrates utilized …

Mustard Greens, Elisabeth Inman

USU Student Organic Farm Newsletter

Mustard greens are the leaves of the mustard plant. The leaves look similar to kale, but are more delicately flavored, with a slight hint of mustard (of course). Mustard greens have large, bright green leaves that are frilled or scalloped around the edge and have a slightly fuzzy surface. Some varieties of mustard greens have a stronger flavor than others. Chinese mustard greens, which are used in many Asian dishes, have a strongly bitter taste.

Swiss Chard, Elisabeth Inman

USU Student Organic Farm Newsletter

Chard, commonly referred to as Swiss chard, belongs to the same family as beets and spinach. Although its name suggests that it originated in Switzerland, chard is actually native to the Mediterranean region and is known to have first been grown in Sicily. The name, Swiss chard, originated because a Swiss scientist determined its scientific name.

Radishes, Brianne Sherwood

USU Student Organic Farm Newsletter

Radishes are often a vegetable that are disregarded as a garnish or something you simply throw on salads, but they have a lot more in them then people typically think. I'll admit, I was one of those people that thought of radishes as quite boring, but the more and more I researched them and experimented, the more I realized that there are so many delicious things you can do with them. For instance, COOKING them- an idea I have previously been against(you aren't supposed to cook radishes, right?) but now love. Look in the "Conquering the Bounty" box for several …

Green Onions, Elisabeth Inman

USU Student Organic Farm Newsletter

Green onions, also known as scallions, have a small root bulb with hollow green leaves. They are harvested for their taste, which is milder than most other onions, and are softer in texture, because they are usually fresher. Because of their mild taste, green onions can be a hidden ingredient in many dishes. They will take on the flavor of any dish and can add a subtle zing or be the star of the show by bringing both flavor and color to a dish. Their small size makes them useful as a garnish. They are often used to garnish salads, …

Isolation Of Antifungal Lactic Acid Bacteria From Food Sources And Their Use To Inhibit Mold Growth In Cheese, Dan Zhao

Master's Theses

A large amount of cheese is lost every year due to mold contamination. Biopreservation, which is the use of biological entities (microbes) and their metabolites to suppress microbial spoilage instead of chemical preservatives has lately gained increasing interest. Lactic acid bacteria (LAB) have the potential for use in biopreservation, because they are safe to consume and naturally exist in many foods. In this study, fifteen strains of lactobacilli isolated from dairy products, vegetables, and fermented pickles were tested by agar overlay assay for their anti-mold activity. Six strains grown on MRS agar showed strong inhibitory activity against a target mold …
