Sensory Evaluations Of Usda Select Strip Loin Steaks Enhanced With Sodium And Potassium Phosphates And Usda Choice Strip Loin Steaks For Comparable Palatability Factors, Lindsey Reynolds
Masters Theses & Specialist Projects
The cyclic nature of the beef industry is dependent on the supply and demand transaction initiated by consumers’ acceptability of quality meat products. When purchasing beef at the grocery store, consumers are dependent on USDA grades and visual appraisal; consumers expect consistency in products. Upon this appraisal, quality is determined by the color, marbling content, and texture of a particular retail cut, as well as cooked characteristics of tenderness, flavor, and juiciness. Variability in meat tenderness is a major quality defect of beef (Morgan et al., 1991b; Smith et al., 1992). A common practice used by beef processors to extend …

Economic Impacts Of Drought On Kentucky Corn, Hay, And Soybeans, Kortney E. Craft
Masters Theses & Specialist Projects
Understanding climatic impacts is important if we are to comprehend the relationship between climate and society. Weather phenomena can have environmental, economical, and social impacts. Drought is the natural hazard that affects people the most. It is also the most complex and least understood. There is no one universally accepted definition for drought which makes its examination difficult. Droughts’ duration is also difficult to determine because it has no clearly defined onset and end. Also, drought varies both geographically and temporally making uniform drought monitoring difficult. Since drought is difficult to monitor and access, drought impacts are often poorly documented. …

Agricultural Contaminant Source And Transport In A Karst Groundwater Basin, Patricia Kambesis
Agricultural Contaminant Source And Transport In A Karst Groundwater Basin, Patricia Kambesis
Masters Theses & Specialist Projects
Agricultural land use in areas that are located in karst groundwater basins negatively impact groundwater quality because karst terrains provide multiple, direct hydrologic connections from the surface into karst aquifers. The connections and rapid velocities associated with surface and subsurface flow in karst aquifers allow for contaminants to move quickly into and through a groundwater basin. When groundwater returns to the surface via a spring or springs, any contaminants within the water become part of surface streams and rivers. These in turn, impact water quality in areas located downstream of the spring or springs. The purpose of this study was …

Influence Of Poultry Litter On Dark Tobacco Growth And Soil Nutrient Availability, Jason Simmons
Influence Of Poultry Litter On Dark Tobacco Growth And Soil Nutrient Availability, Jason Simmons
Masters Theses & Specialist Projects
Due to the relatively high value of dark tobacco compared with fertilizer costs, nitrogen is recommended at levels as high as 338 kg ha"1. Such rates of inorganic fertilizers increase the osmotic pressure of the soil solution and soil acidity, often causing reduced stands, Mn toxicity, Mo and Ca deficiencies, and reduced yield and quality of the cured leaf (Sims et al., 1984). Poultry litter utilized as a nutrient source is an inexpensive alternative to this dilemma due to its relatively neutral or alkaline composition. However, due the amount of chloride present in poultry litter, the University of Kentucky advises …

Efficacy Of Sucker Control Method And Effect Of Topping Height On Axillary Bud Growth In Dark Fire-Cured Tobacco, Leslie Thompson
Masters Theses & Specialist Projects
The removal of terminal buds (topping) and sucker control are two practices that have an impact on yield and quality of dark tobacco (Nicotiana tabacum L.). Topping breaks apical dominance and encourages the growth of axillary buds (suckers). Following topping, growth regulator chemicals known as suckercides are commonly used to prevent axillary bud growth. Research has demonstrated that topping time, height, and sucker control method influence the quality and yield of the final product. Delaying topping past a critical developmental stage has been shown to reduce leaf yield. Topping height varies among geographical regions with most dark tobacco producers topping …
