The Western Kentucky University Horticultural Gardens: A Design & Implementation Plan, Catharine Schriver
The Western Kentucky University Horticultural Gardens: A Design & Implementation Plan, Catharine Schriver
Masters Theses & Specialist Projects
The purpose of this thesis was to design a master landscape plan rnd serve as a preliminary planning tool for the development of Horticulture Gardens at Western Kentucky University. The planning process involved the development of a mission statement and goals for the gardens, analysis of the site, and design of a landscape plan for the proposed six acre Horticultural Gardens located at the WKU farm. Other areas related to the Garden's development explored in the thesis include: an outline of course learning objectives that could be achieved through learning activities conducted at the Horticultural Gardens, an examination of ways …
Evaluation Of Imazaquin, Imazethapyr & Postemergence Herbicide Combinations For Control Of Johnsongrass (Sorghum Halepense) In Soybeans (Glycine Max), Terry Mashburn
Masters Theses & Specialist Projects
Johnsongrass (Sorghum halepense) competition in soybeans (Glycine max) has adverse effects on soybean yields. Profitable soybean production in Kentucky and the Southeastern United States has depended upon good, cost effective johnsongrass control. Several herbicides have been developed to control johnsongrass in soybeans. Four of these recently developed compounds were imazaquin (2-[4,5-dihydro-4-methy1-4- (1-methyl-ethyl)-5-oxo-1H-imidazo1-2-y1]-3-quino1inecarboxy1ic acid), imazethapyr (+/-)-2-C4,5-dihydro-4-methy1-4-(1-methy. lethyl)-5-oxo-IH-imidazol-2-y1)-5-ethy1-3-pyridinecarboxylic acid, quizalofop 2-[4-[(6-chloro-2-quinoxalinyl) oxylphenoxyjpropaonic acid,ethyl ester, and analog of quizalofop (DPX Y6202-31).
Field experiments were conducted in 1986 to evaluate (a) the effectiveness of imazaquin and imazethapyr preplant incorporated, postemergence, or in combination with pendimethalin [N-(1-ethylpropy1)-3,4-dimethy1-2.6-dinitrobenzenamine], and (b) herbicide antagonism with fluazifop[butyl(R)-2-(4-[(5- trifluoromethy 1 …
The Effects Of Within-Row Spacings & Cultivars On The Yield Of Bush Snap Beans (Phaseolus Vulgaris L.), Timothy Hafner
The Effects Of Within-Row Spacings & Cultivars On The Yield Of Bush Snap Beans (Phaseolus Vulgaris L.), Timothy Hafner
Masters Theses & Specialist Projects
The effects of within-row spacings and cultivars on the yield of bush snap beans (Phaseolus vulgaris L.) were studied in two experiments. In each experiment, two cultivars and four within-row spacings (8, 15, 23 and 30 cm) were arranged in a split-plot with four replications. Spacing treatments were the whole plots and cultivars were the split plots. In 1988, the two cultivars were 'Blue Lake 274' and 'White Half Runner'. In 1989, the cultivars were 'Blue Lake 274' and 'Kentucky Wonder 125'. All rows were spaced 91 cm apart. Pods were harvested and oven dried. The data were subjected …
The Effect Of Phosphorous Placement & Rate On Phosphorus Uptake, & Growth & Yield Of Tomatoes, Christopher Thompson
The Effect Of Phosphorous Placement & Rate On Phosphorus Uptake, & Growth & Yield Of Tomatoes, Christopher Thompson
Masters Theses & Specialist Projects
Research was undertaken in the summer of 1989 to determine the effect of phosphorus placement on the yield and quality of field grown tomatoes Lycopersicon esculentum. A subsequent study was undertaken in the winter of 1989 to determine the effect of phosphorus rate and placement on the early growth and phosphorus uptake of young tomatoes in the greenhouse.
The purpose of this study was to attempt to find the most efficient placement and rate of supplemental phosphorus when growing tomatoes. It has been shown that placing phosphorus in a concentrated zone in contact with plant roots results in more …
The Short-Term Effects Of Manganese Toxicity On Ribulose 1,5 Biophosphate Carboxylase In Tobacco Chloroplasts, Kerrie Elliott
The Short-Term Effects Of Manganese Toxicity On Ribulose 1,5 Biophosphate Carboxylase In Tobacco Chloroplasts, Kerrie Elliott
Masters Theses & Specialist Projects
The short-term effects of manganese toxicity on ribulose 1,5 bisphosphate carboxylase (Rubisco) activity and concentration in tobacco chloroplasts were examined. The activity of the enzyme from both manganese-treated and control plants was determined 6, 12, 18, 24 , and 48 h after introduction of manganese (80 mg/Li. Enzyme activity was determined by monitoring rates of radioactive CO2 fixation into acid stable products. A slight stimulation of the enzyme's activity was noted in experimental plants after 18 h of exposure to manganese as compared with control plants. A decrease in the enzyme's activity in experimental plants was noted after 48 …
