Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks Nov 2018

Profitability Of Developing Beef Heifers On Stockpiled Winter Forages, Zachary David Mcfarlane, Chris Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

We estimate the profitability of developing heifers on one stockpiled cool-season grass and two stockpiled warm-season grasses during the winter months by comparing distributions of net present value (NPV) over an 11-year useful life. Furthermore, distributions of payback period and the break-even price for each calf over the heifer’s production life were generated for each forage species. These results are compared across forages as well as to a simulated drylot system for heifer development. Data comes from a grazing experiment in Tennessee, where heifers grazed big bluestem and Indian grass combination (BBIG), switchgrass (SW), or endophyte-infected tall fescue (TF) pastures. …

Price Seasonality In The Catfish Value Chain In Uganda, James O. Bukenya Aug 2018

Price Seasonality In The Catfish Value Chain In Uganda, James O. Bukenya

Professional Agricultural Workers Journal

Seasonal patterns in production and demand are common in many agricultural markets. Charting these patterns provides information that complements fundamental and technical analyses. It is in this spirit that this paper seeks to examine price seasonality in the catfish value chain in Uganda. The analysis draws on monthly prices taken from secondary source recorded data and uses moving average index to chart price patterns. The results reveal distinct seasonal patterns in the farm-gate, ex-vessel, retail, and wholesale market channels. Across market channels, the results for farm-gate versus ex-vessel prices reveal that farm-gate prices are more affected by seasonal effects compared …

Subsidies And The Significance Of Ethanol In Corn Markets, Nathan Goldschlag Jan 2018

Subsidies And The Significance Of Ethanol In Corn Markets, Nathan Goldschlag

The Pegasus Review: UCF Undergraduate Research Journal

The empirical relationship among corn prices, ethanol production, and government subsidies is investigated. An econometric model of the demand for corn is proposed and then estimated with two stage least squares. The estimated demand function is used to evaluate the effects of changes in ethanol markets on domestic corn markets. The results show that an increase in the price of ethanol increases both the equilibrium quantity demanded and price of corn. Agricultural subsidies are then brought under question in light of econometric evidence and coupled with current trends in the ethanol and corn industries.

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne Jan 2018

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne

Human–Wildlife Interactions

The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …

Using 3 Dimension Health Vegetation Index Point Clouds To Determine Hlb Infected Citrus Trees, Joseph Cerreta, Ashley Hanson, Julianna E. Martorella, Stacy Martorella

Journal of Aviation/Aerospace Education & Research

Three-dimensional NDVI point clouds can be an innovative method for detecting Huanglongbing (HLB) disease in citrus trees. In February 2018, an Unmanned Aircraft System (UAS) captured narrow-band multispectral images to detect healthiness variations of infected citrus trees. A 30-acre section of a citrus grove in Florida with a known HLB infection was examined to determine if three-dimensional Normalized Difference Vegetation Index (NDVI) point clouds can indicate healthiness variations in HLB-infected citrus trees and how three-dimensional NDVI point clouds compared to two-dimensional NDVI reflectance maps for detecting healthiness variations in HLB-infected citrus trees. Wilcoxon Sign Rank testing compared Whole-Tree Vegetation Indices …
