The Illinois Ferns Of Coles, Clark, And Cumberland Counties, Bill N. Mcknight Jan 1980

The Illinois Ferns Of Coles, Clark, And Cumberland Counties, Bill N. Mcknight

Masters Theses

A study of the ferns in East Central Illinois was conducted between the spring of 1976 and the spring of 1980. The counties surveyed were Coles, Clark, and Cumberland. The majority of the field investigation was conducted near the moraines and waterways which dissect the area.

Keys are provided for the families, genera, and species. There are also descriptions and illustrations for each species considered. The description covers the gross external morphology and any variations that occur. Also included are habitat preference and local distribution data. In addition, there are ethnic comments dealing with the derivation of both folk and …


Analyses Of Illinois Wild Turkey Habitat And April Foods, Kim D. Price Jan 1980

Analyses Of Illinois Wild Turkey Habitat And April Foods, Kim D. Price

Masters Theses

A vegetative analysis of turkey habitat was conducted in Alexander, Jackson, Union, and Calhoun Counties, Illinois. From these studies it was determined that turkeys inhabit relatively open stands of timber with agricultural fields and forest clearings in close proximity. Species of Quercus comprise approximately 40% or more of the tree species sampled, with Q. alba, Q. rubra, and Q. velutina being the most dominant. Found growing in association with Quercus are species of Carya, Cornus florida, Acer saccharum, Sassafras albidum, Fraxinus americana, and Ulmus rubra, in varying concentrations. The examination of food …


A Test Of The Fertilizing Value And Inhibitory Qualities Of Sewage Sludge, Gregory D. Kugler Jan 1980

A Test Of The Fertilizing Value And Inhibitory Qualities Of Sewage Sludge, Gregory D. Kugler

Masters Theses

Three sludges - aerobic, anaerobic, Milorganite, and peat moss were tested for fertilizing ability, seed inhibition, and chemical composition. Using green bean (Phaseolus sp.) and rye grass (Lolium perenne) seeds in two sludge amended soils, a greenhouse study indicated growth enhancement for the rye grass and variable results for the green beans. Algal and fungal contaminations were problems. Seeds germinated in sludge extract were inhibited, but no correlation with the chemical analyses could be established. Only Milorganite had a heavy metal content significantly higher than the soils tested.


The Effects Of N-Serve On The Availability Of Urea And Ureaformaldehyde Nitrogen On Lolium Perenne L., Ronald E. Schroll Jan 1980

The Effects Of N-Serve On The Availability Of Urea And Ureaformaldehyde Nitrogen On Lolium Perenne L., Ronald E. Schroll

Masters Theses

Laboratory experiments were conducted to determine the effect of "N-Serve" (DOW) on the availability of urea nitrogen and the subsequent greening effect on perennial ryegrass (Lolium perenne L.) seedlings as compared to the availability of nitrogen and subsequent greening from a controlled release ureaformaldehyde fertilizer. A low organic matter sandy loam soil and a high organic matter clay loam soil were used in this study. Soil treatments of urea and ureaformaldehyde fertilizers were applied and incorporated at concentrations of 0, 25, 38, and 50 ppm-N. N-Serve at concentrations of 0.25, 0.50, and 1.0 ppm active ingredient were applied and …


The Influence Of Atrazine (2-Chloro-4-(Ethylamino)-6-(Isopropylamino-S-Triazine) On The Severity Of Gibberella Zeae-Induced Seedling Blight Of Corn, Louis A. Heaton Jan 1980

The Influence Of Atrazine (2-Chloro-4-(Ethylamino)-6-(Isopropylamino-S-Triazine) On The Severity Of Gibberella Zeae-Induced Seedling Blight Of Corn, Louis A. Heaton

Masters Theses

Three corn inbreds were grown in artificially inoculated, steamed greenhouse soil amended with atrazine (2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine) to determine the herbicide's effect on the severity of Gibberella zeae (Schwabe) Petch-induced seedling blight. Corn inbreds used were Gibberella-resistant (FR632), Gibberella-intermediate (FRMo17), and Gibberella-susceptible (C123HT). Soils were amended with atrazine at rates of 2, 15, and 30 ppm.

Susceptible inbred seedlings showed no response to the herbicide with symptims equally severe in controls and all 3 concentrations of atrazine. Intermediate inbred seedlings grown in all atrazine amended soils showed significantly more severe disease symptoms than controls. Soil amended with …


A Taxonomic And Ecological Study Of The Lichens Of "Rocks Park" In Coles County, Illinois, Robert Arthur Williams Jan 1980

A Taxonomic And Ecological Study Of The Lichens Of "Rocks Park" In Coles County, Illinois, Robert Arthur Williams

Masters Theses

The lichen flora of "Rocks Park", Coles County, Illinois, was studied extensively. The tract (sec 17, T12N,R10E), which is located in east-central Illinois, was selected for study because of its diversity of habitats for lichen growth. A literature review of the studies of the lichens of east central and southern Illinois and nearby Indiana is included. The area is heavily dissected by the Embarrass River and a few small tributaries. The major vegetation type is oak-hickory forest. This tract was found to have four distinct habitats with different lichen associations. The habitats described are the following:

  1. Open Field Area
  2. Sparsely …
