An Economic Study Of The Relative Profitability Of Alfalfa Production And Marketing Practices, David Claycomb
An Economic Study Of The Relative Profitability Of Alfalfa Production And Marketing Practices, David Claycomb
Masters Theses & Specialist Projects
The seasonality of the price of alfalfa hay in Kentucky was studied as well as the potential cost or profitability of storage of this hay. Economic comparison of alfalfa hay production to other farm enterprises was carried out. In addition, an estimate of the value of two qualities of alfalfa hay was calculated based on 1991 prices. The analysis of 41 years of marketing data demonstrated significant differences (P<.01) in price with seasonal lows in June/July and a steady increase in price to a high in March. In general (based on $100 per ton hay and 12% interest) the alfalfa hay producer could lose from $5 to $10 storing hay and selling at a later date. There were some specific conditions where he might have realized a return to storage of $0.16 to $1.48 per ton. A further evaluation of average (KY Feeder) and good (KY Pride) quality hays indicated that current prices of $70-$75 and $100 per ton respectively were the prices where a dairyman would be able to include this hay in the cow's total diet. Even with problems of quality and quantity of alfalfa hay, the economic returns to the production of alfalfa hay were favorable when compared to other crops in Kentucky with the additional benefit of alfalfa being a crop that can result in reduced soil erosion from sloping land. Returns above variable costs can be from $120 to $400 per acre depending upon yield and sale price. However, an understanding of seasonality of price as well as storage costs need to be considered by alfalfa hay producers to assure realizing the above returns.

Effects Of Soybean Cultivars And Planting Dates On Biomass Production, Aslam Tawhid
Effects Of Soybean Cultivars And Planting Dates On Biomass Production, Aslam Tawhid
Masters Theses & Specialist Projects
Soybean [Glycine max (L.) Merr.] is a valuable source of edible food and organic nitrogen. Soybean cultivar development and cultural practices have been directed toward seed production rather than forage or green manure production. Recent environmental concerns have resulted in renewed interest in the use of organic matter in agriculture. The objective of the present investigation was to determine the effects of cultivar maturity differences and planting dates on biomass production of soybean. The research was conducted on the Western Kentucky University Farm in 1993. The experimental design was a split-split-plot with four replications. The three planting dates (June 2, …
Oats As A Companion Crop For Alfalfa: Establishment Methods, Shannon Hurley
Oats As A Companion Crop For Alfalfa: Establishment Methods, Shannon Hurley
Masters Theses & Specialist Projects
Companion crops are commomly seeded with alfalfa in the spring as an establishment method. The objectives of this research were to evaluate the performance of seedling Alfalfa (Medicago sativa L.) in terms of yield when grown with spring oats (Avena sativa) as a companion crop and to evaluate the amount of weed control in the alfalfa companion crop seeding, under various management practices. Six establishment treatments were imposed: (1) solo-seeded alfalfa raised according to standard procedures recommended for Kentucky, (2) solo-seeded alfalfa with a herbicide treatment, (3) alfalfa seeded with an oat companion crop and treated with a herbicide, (4) …

Clock Control Of Circadian Changes Of Ommatidial Structure In The Cockroach, Leucophaea Maderae (L.), Zhuming Zhang
Clock Control Of Circadian Changes Of Ommatidial Structure In The Cockroach, Leucophaea Maderae (L.), Zhuming Zhang
Masters Theses & Specialist Projects
All eukaryotic organisms display rhythms which persist under constant environmental conditions with periods of approximately, but very seldom exactly, 24 hours. Such rhythms are "circadian" and are driven by an internal "biological clock." Circadian rhythms of locomotor activity, retinal sensitivity to light and ommatidial morphology have been characterized in the cockroach, Leucophaea maderae (L.). It is not known whether the same clock(s) controls both circadian rhythms of electroretinogram (ERG) amplitude and morphological changes of the compound eye. In order to determine whether the location of the clock that controls morphological changes is in the same location as the one that …
In Vivo & In Vitro Effects Of Light On Ommatidial Morphology In The Cockroach, Leucophaea Maderae, Channon Yule
In Vivo & In Vitro Effects Of Light On Ommatidial Morphology In The Cockroach, Leucophaea Maderae, Channon Yule
Masters Theses & Specialist Projects
Clock-driven endogenous circadian rhythms in ommatidial morphology have been reported in Leucophaea maderae. The parameters used to measure changes in ommatidial morphology over time were palisade layer and rhabdom areas and the organization of lightscreening pigment granules about the rhabdom. The fact that the palisade layer area only partially returned to the light-adapted state in vivo during subjective midday was indicative of a passive mechanism, not involving the clock output. Complete return of the palisade layer area to the light-adapted state during the daytime in animals held under LD 12:12 indicated light might play an active role. Temporal changes …

Purification & Characterization Of A Deoxyribonuclease From Etiolated Soybean, Cunyong Xu
Purification & Characterization Of A Deoxyribonuclease From Etiolated Soybean, Cunyong Xu
Masters Theses & Specialist Projects
A deoxyribonuclease (DNase) has been isolated from a purified preparation of soybean nuclei. The procedure, involving solubilization of proteins using ammonium sulfate, Sephadex G-75, DEAE-Cellulose and CMSephadex chromatography and non-denaturing polyacrylamide gel electrophoresis, resulted in a 554-fold purification with a yield of 6% of the enzyme. The purified enzyme had a molecular weight of 60 KDa as monitored by non-denaturing polyacrylamide gel electrophoresis. In addition, high-molecular-weight (HMW) soybean DNA, essentially free from protein, RNA and other contaminates, has been isolated from soybean to be used as a substrate for the enzyme. Enzyme activity was directly proportional to the concentration of …
