A Baseline Study Of Biofuel Feedstock Growth On Non-Traditional Agronomic Land In Utah, Dallas A. Hanks
A Baseline Study Of Biofuel Feedstock Growth On Non-Traditional Agronomic Land In Utah, Dallas A. Hanks
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Nearly all highway, airport, and military areas in Utah cost money to maintain and are often safe harbor for noxious weeds and pests. This project hypothesized that money could be saved and biofuel feedstocks could be grown in these areas, improving sustainability. Agronomic conditions and growth methods were tested to determine if biofuel feedstock production could occur on these marginal, non-traditional plots of land. Models developed illustrate that maintenance costs for these areas can be nullified if oilseed crops grown yield 600 pounds/acre and are used for biodiesel production. This feedstock yield would result in approximately 25 gallons of biodiesel …
Comparative Growth Of Spring-Planted Canola, Brown Mustard And Camelina, A. D. Pavlista, D. D. Baltensperger, T. A. Isbell, G. W, Hergert
Comparative Growth Of Spring-Planted Canola, Brown Mustard And Camelina, A. D. Pavlista, D. D. Baltensperger, T. A. Isbell, G. W, Hergert

With increased emphasis for diesel substitution, production of brown mustard (Brassica juncea), canola (Brassica napus) and camelina (Camelina sativa) used as biodiesels may increase in the High Plains. Since these are new crops to this region, understanding their growth is critical for their acceptance. The objective was to elucidate the growth pattern of these crops when spring-planted in western Nebraska. Field trials were conducted in 2005, 2006 and 2007 with early May planting. Plots were seeded 2 cm deep at 200 plantsm−2. Four plants were destructively sampled at about 28, 40, 53, 61, and …

Insect damage to prairie cordgrass, Spartina pectinata Link., is conspicuously high in Illinois, where attempts to collect native seed show the majority of spikelets damaged with small holes. Dissection of spikes during summer reveals minute caterpillars boring though glumes and feeding on florets inside. In 2009–2010, panicles of prairie cordgrass from across its native range were used to estimate the percentage of insect-related damage and losses to seed production. Collections of caterpillars from panicles and stems were used to identify one floret-feeding species, estimate its distribution in the central USA, and assess its feeding patterns within spikes. Insect feeding damaged …
