Effects Of The Inclusion Of Rice Hull Derived Bio-Oil On Wood Pellet Production, Tyler E. Lowe
Effects Of The Inclusion Of Rice Hull Derived Bio-Oil On Wood Pellet Production, Tyler E. Lowe
Theses and Dissertations
Wood pellet production has become an advancing industry for the sake of reducing greenhouse emissions into the atmosphere especially, in European Union countries. Researchers and industry executives seek new methods and materials to improve the pelletization process. Rice hulls or husks has the potential to aid in wood pelletization as they possess high calorific values. This study focuses on using rice hull derived bio-oil from pyrolysis, which will also decrease ash content, as an additive to aid in the wood pelletization process. Using two groups of rice hull derived bio-oil as an additive in wood pelletization: Group 1 uses heavy …
Precise Nitrogen Recommendations Improve Economic And Environmental Outcomes In Arkansas Rice Production, Cristin Roberts
Precise Nitrogen Recommendations Improve Economic And Environmental Outcomes In Arkansas Rice Production, Cristin Roberts
Graduate Theses and Dissertations
Soil testing has become an increasingly important tool in making agronomically efficient production management decisions. N-STaR is a N test used in rice production and is unique in its ability to selectively quantify soil organic-N compounds which are readily mineralizable for plant N uptake and contribute to growth and yield. This study uses historical (2002–2018) adoption rates of N-STaR, which is funded through Rice Checkoff funds, to calculate the total cost savings from N-STaR adoption. These cost savings alone would be the “typical” benefits used in a benefit-cost ratio of a public ally funded research program like N-STaR. However, we …

Entrepreneur`S Guide To Starting A Rabbit Agricultural Enterprise, Mary Maldonado
Agricultural Education and Communication
At San Luis Obispo, the University Cal Ploy has an Animal Science Department that offers over twenty enterprises pertaining to livestock production which “provide the environment for students to get outside the classroom and work with the animals in teams of students” (Cal Poly 2017-19). As reported from the “Animal Science Department Enterprise Class List”, the classes involved help develop technical skills by having students learn and work in active production settings with livestock such as cows, steers, pigs, lambs, goats, and chickens (Animal Science Department 2017-19). However, when compared to the livestock accounted for at a traditional county fair …

Environmental Tradeoffs In Bioenergy Production And Agricultural Practices, Alicia Lynn English
Open Access Dissertations
The focus of this dissertation is the environmental tradeoffs of stover removal within the Corn Belt. The environmental tradeoffs considered are mainly concerned with managing soil erosion and soil quality. The analysis layers soil characteristics, management strategies and per acre costs using an integrated RUSLE2/WEPS model and an economic optimization model to illuminate a lower bound supply response. Different assumptions were tested in regards to sustainability, prices, and market integration for five states and 18,760 soil types throughout the Corn Belt. Sustainability was defined to limit soil erosion from wind and water to 5 tons/acre/year and the soil organic matter …

The Effect Of Black Plastic Mulch Alone And In Combination With Various Types Of Plastic Row Covers On Production Of Sweet Corn, Morteza Jabalameli
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The effects of black polyethylene (PE) mulch alone and in combination with plastic film tunnels (Agronet, Reemay, whiteperforated, clear, and clear-slitted) were studied on morphology and yield of sweet corn in North Logan, Utah. Yields of "Miracle" sweet corn (Zea mays L.) were increased significantly by using black PE mulch and with a combination of various types of plastic row covers, as compared to unmulched soil. Standard-growth analysis procedures were conducted to verify responses among treatments. Treatment effects were determined by measuring days to first flowering, ear weight, number of side tillers, cob length, cob circumference, cob fill length, number …

Production Of Monoclonal Antibodies Specific For The Gamonts Of Eimeria Tenella, Nancy Carol Larsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Cecal coccidiosis, caused by the protozoan Eimeria tenella, may manifest as a devastating disease in young chickens and result in substantial economic loss for producers. The parasite progresses through a complex life cycle, exhibiting both asexual and sexual (gamont) stages of development. The purpose of this study was to produce a panel of monoclonal antibodies (MoAbs) against epitopes contained on surface antigens (Ags) of the gamonts of E. tenella with the intent of blocking the fertilization process. Gamonts were harvested from infected ceca, partially purified by differential centrifugation throught a discontinuous 5050% Percoll density gradient and used as a …
Alfalfa Production As Related To Irrigation Scheduling: An Economic Perspective, Craig L. Israelsen
Alfalfa Production As Related To Irrigation Scheduling: An Economic Perspective, Craig L. Israelsen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study analyzed the economics of irrigation scheduling for alfalfa hay in the Cache Valley, Utah area. Yield, evapotranspiration (ET) and irrigation drainage loss, along with the costs and returns per acre attributable to irrigation scheduling, were simulated through the use of a computerized plant growth model. The model created yearly "irrigation schedules" for alfalfa hay based on actual climatic, soil and plant characteristic data from the Utah State University Greenville Experiment Station. The model calculated the irrigation schedules based on a soil-water balance equation which never allowed the available soil water to go below the crop stress point.
The …

Estimated Supply Response Of Sugar Beet Production To Changes In Profitableness, Box Elder And Cache Counties, Utah, 1967, Brent W. Spaulding
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The relative profitability of sugar beets and competitive crops were studied in Box Elder and Cache counties, Utah.
Profitability ratios based on enterprise budget data and resource use requirements were used as a basis for comparison. Sugar beets was found to be more profitable than competing crops in returns per acre, in returns to water used and in returns to fixed investment and management. However, sugar beets was found to be less profitable than certain other crops in returns to operating capital and returns to labor. Also, on land rated low in productivity sugar beets was found to be less …

Economics Of Farm Flock Sheep Production In Northern Utah, Bruce E. Nielson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Throughout the history of mankind, sheep have played a very important and unique part in the economies of the world. They have been a source of meat, milk, skins and fiber. They have become adapted to nearly every kind of husbandry, from nomadic types to intensively managed flocks on small farms and have thrived under nearly all climatic conditions, ranging from sub-artic regions of Greenland to hot areas of the Mediterranean countries; from desert areas of Africa to wet lowland of England.
