Preparing Children For A Healthy Marriage, Naomi Brower, Daryl Zadok Budd

All Current Publications

Research indicates that the principles for preparing youth for future healthy marriage relationships include many of the basic principles of good parenting such as a healthy home environment, modeling healthy relationships, being involved in a child’s life, and encouraging healthy choices. Ultimately, as children progress into adulthood they will make their own choices about relationships; however, by providing healthy role models, encouragement, and support, youth will have the framework necessary to develop a healthy and lasting marriage.

Composting Manure And Other Organic Materials, Charles S. Wortmann, Charles A. Shapiro

Department of Agronomy and Horticulture: Faculty Publications

The Composting Process

Composting is the aerobic decomposition of manure or other organic materials in the thermophilic temperature range (104-149oF). Composted material is odorless, fine-textured, and low-moisture. It can be bagged and sold for use in gardens or nurseries, or used as fertilizer on cropland with little odor or fly breeding potential. Composting improves the handling characteristics of any organic residue by reducing its volume and weight. Composting can kill pathogens and weed seeds.

Disadvantages of composting organic residues include loss of nitrogen and other nutrients, time for processing, cost for handling equipment, available land for composting, odors, marketing, diversion …

The Suitability Of Ground Date (Phoenix Dactylifera L.) Pits And Ghaf (Prosopis Cineraria L.) Pods As Horticultural Growth Media Or Soil Amendments, Saeed Khalifa Alshaali

Theses

The UAE and its neighboring countries are encountering scarcity of water resources and soil degradation due to salinization. The current over-exploitation of aquifers by the agricultural sector is a major concern for the government. Open field production of forage as a feed for camels, cows and small ruminants requires particularly high amounts of irrigation water. Greenhouse production of fodder might save water, but would require a suitable growth substrate that is readily available in the UAE, and ideally constitutes a palatable fodder itself. The objective of this study was to evaluate the suitability of ground D.pits and G.pods as growth …

Effect Of Tassel Removal For Baby Corn (Zea Mays L.) Production In Kentucky, Christopher G. Ferguson

Masters Theses & Specialist Projects

Baby corn (Zea mays L.) consists of unfertilized young ears harvested at silk
emergence. The 2011 study was a culmination of four successive years of production
and evaluation of baby corn at Western Kentucky University (36.93 N, 86.47 W). The
objective was to compare the effect of tassel removal on baby corn (BC) production on
four cultivars of corn, two field (‘N77P-3000GT’, ‘N68B-3000GT’) and two sweet
(‘Silver Queen’, ‘Peaches N Cream’). Results indicated that tassel removal gave
significant increases (P<0.01) of BC ears across harvests (H) and cultivars; however, the effect was not consistent over treatments. For harvests, the difference due to detasseling was significant (P<0.05) for H2 and H3, but not significant (P>0.05) for H1 or H4. For cultivars, numerical values were higher for detasseled than non-detasseled treatments in the first three …

Controlled Release Nitrogen Fertilizers In Missouri Cotton Production, Andrea Phillips Jones

Student Theses and Dissertations

Nitrogen (N) is an essential nutrient for cotton (Gossypium hirsutum L.) production. A standard fertilization practice for N in the Mid-South is a split application. However, a single N application at planting would potentially save fuel and labor cost. The objective of this study was to determine the effectiveness of controlled release nitrogen (CRN) fertilizers applied to various soils relative to pre-plant and split application nitrogen fertilizer programs for cotton production. The study was conducted in 2010 and 2011 on a Bosket fine sandy loam, a Tiptonville silt loam soil, and a Sharkey clay soils. At each location, ten treatments …

Cholesterol Lowering Effects Of Milk With Added Phytosterols, Laura Kells Cusack

Master's Theses

Foods incorporating plant sterols (PS) reduce Low-density lipoprotein (LDL) on average approximately 10%. PS with a higher lipid solubility may promote greater reductions. We examined the cholesterol lowering effect of a novel triglyceride recrystallized phystosterol (TRP). Twenty subjects (mean ± SD; age, 56 ± 10 years; BMI, 27 ± 5) with elevated LDL (>100 mg/dL) participated in three 4-week phases; Phase I, 2% milk; Phase II, milk with 2.0 grams (g) free PS; Phase III, milk with 2.0 g TRP. Before and after each phase two fasting blood draws were obtained for determination of serum cholesterol. Between the 2% …

Agricultural Research Magazine

The only thing that stands between the United States and an invasion of cattle-killing screwworms is a daily flight of airplanes flooding a 100-mile-wide section of the Isthmus of Panama with male screwworm flies raised in a laboratory and sterilized with radiation in Panama. The screwworm infestations of the past would probably come back if the releases stopped for a couple of months or so, says Dan Strickman, Agricultural Research Service national program leader for veterinary and medical entomology.

“This is a great example of agricultural research changing the history of this country, and it’s a cutting-edge example of integrated …

Evaluation Of Viability Of Lactobacillus Acidophilus La-5 During Simulated Digestion Process Using A Dynamic In Vitro Model, Jenifer Tharani

Master's Theses

In recent years, there has been an upsurge in medical research assessing the therapeutic benefits of probiotic bacteria and growing commercial interest in food fortification with these bacteria. Probiotic bacteria such as L. acidophilus are known to be predominant Lactobacilli species in the intestinal tract of healthy humans and suggested to provide clinical health benefits such as enhancement of immunity against intestinal infections, prevention of diarrhea and hypercholesterolaemia and improvement in lactose utilization. Many studies have demonstrated the possibility of incorporating probiotic bacteria in an ice cream matrix and shown its viability can be maintained throughout the shelf life of …

Masters Theses & Specialist Projects

This research is a two year study on the effects of endomycorrhizae on vegetable production using conventional vs. organic practices. Objective of this study was initiated to determine if mycorrhizae improve yield, available soil nutrients and soil quality from two different fertilizer sources. Measurements were taken on yield, available soil nutrients, and soil quality in comparison of glomalin production and soil loss percentage. Two plant species were chosen, Tomatoes (‘Big Beef’) and Bush Beans (‘Tenderette’). A randomized split block 2 x 3 factorial treatment arrangement was used with two crops and three different inputs: Mo- 0 mycorrhizae, M1- recommended rate, …

Serving As Suppliers To Institutional Foodservices: Supply Chain Considerations Of Small And Medium Scale Specialty Crop Producers, Laura Westray

All Theses

Institutional foodservice, which includes schools, hospitals, and long-term care facilities, is an important food marketing channel. The centralized nature of the US food system effectively, and supply, logistic and other constraints, effectively precludes small and medium scale (SMS) specialty crop producers from serving as suppliers to these types of operations. Passage of The Food Safety Modernization Act (FSMA) and increasing public attention to food safety issues, further complicates this matter. While the FSMA Tester-Hagen Amendment provides regulatory exemptions for SME producers, it is likely that in the future food purchases on or behalf of institutions will require more stringent food …

The Effect Of Chlorine And Ozone In Controlling Microbes On Organically Grown Cilantro And Carrots, Adam Holtz

BioResource and Agricultural Engineering

This senior project investigates the relative efficacy of ozonated water and chlorinated water for the purpose of sanitizing freshly-harvested organic produce. The aim of this study was to assist the Cal Poly Organic Farm in deciding whether or not to invest in an ozone generator. The crops used for testing were grown organically in the same field. Carrots and cilantro were harvested and promptly treated with 5 ppm ozone solution or 25 ppm sodium hypochlorite solution. Carrots were sampled at 0, 7, and 14 days storage to determine microbial populations. Cilantro was similarly tested at 0, 6, and 12 days …

Determining The Difficulties Of Ornamental Horticulture Programs, Elizabeth Basham

Agricultural Education and Communication

The purpose of this senior project was to develop a survey to determine the difficulties that high school ornamental horticulture instructors were facing with their programs. Many schools throughout California have faced difficulties with their programs and have had to limit the offerings of the courses that would have been available to their students. Based upon the results from the survey it was determined that many of the instructors felt that their programs had been declining in success due to budget limitations, student involvement, standardized testing requirements and community support. The results of the survey can be utilized to aid …

Nest And Brood Site Selection And Survival Of Greater Prairie-Chickens In The Eastern Sandhills Of Nebraska, Lars Anderson

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

Greater prairie-chickens (Tympanuchus cupido pinnata) are a grassland bird species of conservation concern. Although greater prairie-chickens have declined over much of their range, the Nebraska Sandhills has the largest population in North America. However, the responses of nest and brood site selection and survival to vegetation characteristics are unknown. I studied prairie-chickens on private rangelands in Rock and Brown Counties from 2009-2011. I fitted 139 females with radio collars to locate nest and brood sites and to determine nest and brood survival rates. Females were trapped on leks during the breeding season and I monitored them throughout the …

Temporal Aggregation And Treatment Of Zero Dependent Variables In The Estimation Of Food Demand Using Cross-Sectional Data, Kristyn Leffler

All Theses

This study analyzes U.S. consumers' demand for eight food commodity groups: Cereal and Bakery goods, Meat and Eggs, Dairy, Fruits and Vegetables, Nonalcoholic Beverages, Fats and Oils, Sugar and Sweets, and Miscellaneous goods. The estimation of the demand system of equations is carried out using the EASI demand model of Lewbel and Pendakur (2009) and five years of data (2002-2006) from the Nielsen Homescan program. Two different levels of temporal aggregation, monthly and the average month within a year, referred to as 'annual' were considered. Using the monthly data, I evaluated the performance of two econometric methods to account for …

Diversification Of Organic Cropping Systems With Cover Crop Mixtures: Influence On Weed Communities, Soil Microbial Community Structure, Soil Moisture And Nitrogen, And Crop Yield, Samuel E. Wortman

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

Organic grain cropping systems typically depend on intensive mechanical cultivation for weed control and manure or compost applications to meet plant nutrient demands. However, cover crops may contribute to weed suppression and soil fertility, potentially increasing crop yield and sustainability of the system. The utility of individual cover crop species have been well documented, but the agronomic benefits of diverse cover crop mixtures have received less attention. Cover crop mixtures are an appealing option for farmers, as increasing species diversity has been shown to increase resource-use efficiency, stability, resiliency, and productivity of plant communities. Despite the growing interest in cover …

A New Approach Tomolecular Plant Breeding, Dennis O’Brien, Jean-Luc Jannink

Agricultural Research Magazine

An ARS scientist in Ithaca, New York, is using a new statistical approach to help speed the development of improved varieties of crops.

Plant breeders constantly strive to breed new varieties that yield more, resist emerging pests and pathogens, tolerate heat and drought, and grow in marginal soils and environments. Increasingly, molecular tools are used to speed those efforts. By identifying genes associated with desirable traits, scientists don’t have to wait for timeconsuming field observations.

“To grow wheat and evaluate it for traits in the field takes 5 to 9 years. Using genomic data, we can do it in about …

What's In Your Blood? The Ongoing Hunt For Metabolites, Marcia Wood, John W. Newman

Agricultural Research Magazine

At any given time, blood circulating through your body carries thousands of small molecules known as “metabolites.” Medical and nutrition researchers are eager to discover more about these compounds—amino acids, sugars, fats, and more—that are formed in and by our bodies.

Metabolites are of interest because the presence and concentrations of some of them can provide meaningful profiles, sometimes referred to as “metabolic signatures” or “fingerprints.”

In the future, for instance, yourmetabolic fingerprint—detected in a small sample of blood taken for your annual physical examination—might prove to be a reliable indicator of your health and a predictor of certain diseases. …
