Incidence And Life History Of Beech Scale, Initiator Of Beech Bark Disease, In The Great Smoky Mountains National Park, Robert Angelo Vance

Masters Theses

American beech, Fagus grandifolia Ehrlich, in eastern North America are currently threatened by the devastating beech bark disease. This disease is caused by the fungal pathogens, Nectria coccinea var. faginata Lohman, Watson and Ayers, and Nectria galligena Bres., which infect trees that are predisposed by infestations of beech scale, Cryptococcus fagisuga Lindinger. In 1993, beech bark disease was discovered in the Great Smoky Mountains National Park (GSMNP).

In 1994, a 2-year cooperative research project involving the National Park Service and the University of Tennessee Agricultural Experiment Station was initiated to study several aspects of beech bark disease in the GSMNP. …

Pb897 Commercial Bush Snapbean Production, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

Snapbean production in Tennessee ranges from 6,000 to 9,000 acres and contributes $7 to $9 million annually to the state’s economy. The major production area is located within a 50-mile radius of Crossville, with some early production in the south central portion of the state. Small acreages are grown throughout the state for local sales.

Presently, the acreage is about 45 percent processing and 55 percent fresh market. Fresh market packing operations have increased about five-fold in the last few years.

The varying elevations and temperatures enable producers to plant early at lower elevations and make summer plantings at higher …

Pb1544 Comparing The Cost Of Broadcasting Versus Injecting Nitrogen In No-Tillage Corn, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

No-tillage has become a popular production option with many Tennessee farmers in the past 20 years. In 1993, no-tillage production systems were used on 290,000 acres of corn in Tennessee, or 44 percent of the total corn acreage planted in the state (TDA). Many farmers see no-tillage as a way to reduce the cost of growing corn. Others have chosen no-tillage as a way to comply with governmental regulations covering the farming of highly-erodible soils.

Input levels and prices are important to consider in any production system. A major expense in corn production is nitrogen (N) fertilizer. No-tillage budgets published …

Using Gis To Analyze The Precipitation Regime Of The Great Smoky Mountains National Park, Tn/Nc, Thomas Bryan Coffey

Masters Theses

Studies or research conducted in remote areas of the Great Smoky Mountains National Park (GSMNP) involving the use of precipitation data, have often resolved to utilizing the precipitation data from weather stations located in more easily accessible areas or from nearby towns and cities. This study was conducted to determine an accurate annual average precipitation value for the GSMNP and to develop an average annual precipitation database (coverage) for the park as a whole. Precipitation data from 51 weather stations in and around the GSMNP were placed into the geographic information system (GIS), ARC/INFO, and three methods were implemented to …
