Impact of preventative fungicide practices on Mid-South soybean (Glycine max) grain development, quality, and economic return

Floyd, Chase Alan 03 May 2019 (has links)
The need for profitable soybean production practices gain continually with increasing input costs and reduced profit margins. Constant cultivar and product developments has resulted in limited current data available regarding the profitability of preventative fungicide applications and physiological benefits that can occur from these applications. Research was conducted during 2017 and 2018 to determine optimal fungicide application timing, while assessing multiple fungicide options and resulting effect on soybean grain yield, seed quality, and profitability. Additional research was conducted to determine optimal row spacing, planting date and fungicide application combinations to maximize soybean production profitability. These data suggest using multi-mode of action fungicide treatments increased soybean grain yield, regardless of application timing. These data also suggest, profitability from application of multi-mode of action fungicides can be observed at lower adjusted market prices.

Evaluation of Cobb MV × Cobb 500 broiler response to various nutrient regimens to maximize performance and economics

Hirai, Rosana 09 August 2019 (has links)
To maximize the economics of a new commercial broiler cross, research on its nutritional specifications is necessary. Study 1 investigated the effects of feeding four amino acid densities (AAD) on performance and yield of Cobb MV × Cobb 500 broilers at d 33 and 36. Data demonstrated a stepwise decrease in feed conversion ratio (FCR) as AAD level increased. Improvements in performance, processing, and economic return were observed when feeding higher AAD levels. Study 2 estimated the digestible lysine (dLys) requirements of Cobb MV × Cobb 500 broilers from d 0-14 and evaluated the impact of varying starter dLys levels on their performance, processing, and economic return during a 42 d grow-out. Data suggested that d 0-14 dLys requirements varied based on broiler response and statistical model. Improvements in overall performance was observed when feeding ≥1.12% dLys during the starter phase. The greatest economic return was associated with feeding starter dLys of 1.20%. Due to the potential interaction between AA and apparent metabolizable energy (AME), Study 3 examined the response of Cobb MV × Cobb 500 to varying dLys and AME levels from d 0-14 on d 0-42 performance and processing. A dLys × AME interaction was observed for d 0-28 FCR and for dLys and AME for early performance parameters. However, this significance was lost by the end of the study. Due to the variation in broiler response to feeding strategies at different ages, Study 4 evaluated the impact of varying dLys and AME levels from d 14-28 on performance and processing of 42-day old Cobb MV × Cobb 500 broilers. Data demonstrated significant dLys × AME interactions for d 14-28 and 14-35 FCR, as well as significances for main effect of dLys and AME for performance and processing (d 42). Feeding grower diets formulated to 1.18% dLys + 3028 kcal/kg AME was the most profitable diet. Overall, this research demonstrates that higher AAD improved broiler performance, especially ≥1.12% starter dLys. Varying dLys and AME during the starter phase did not affect performance at d 42; however, it did when this regimen was exercised during the grower phase.

Vplyv energetických opatrní na ceny prevádzky budovy / The Impact of Energy Saving Measures on Prices of Building Operation

Kabzáni, Matej January 2017 (has links)
The theme of the diploma thesis "Effect of energy care on building prices" is the design and assessment of several measures, two of which generally lead to lower heating costs. The diploma thesis deals with evaluation of the current state of the family house and determination of PENB before the construction modifications and subsequently after the construction modifications, defining subsequent measures for energy saving implementation, both in terms of energy, economic and also environmental.

Využití produkčních rybníků pro sportovní rybolov na Třeboňsku a Novohradsku / Usage of production ponds for sport fishing in area of Třeboň and Nové Hrady

VIDRMAN, Jan January 2008 (has links)
After a year 1989 opened new possibilities for sport fishing. The biggest change in this direction is the possibility of fishing in private fishing grounds. Fishing firms and the other private subjects started to derive benefit from this kind of fishing. This phenomenon is caused by increasing of the fishing pressure on wild waters and higher buying power of the population and its willingnes to spend more money for quality leisure time.Because most of these fishing grounds belong to commercial producers of market fish and sport fishing is realized as a form of economic mining fish on rod as a payed service. This fact causes different way of organisation and different rules of sport fishing.

Vliv provedení zateplení budovy na výdaje spojené s jejím provozem / Thermal Insulation Effect of the Building on the Operation-Related Expenses

Skupa, Jan January 2021 (has links)
The diploma thesis entitled The influence of building insulation on the costs associated with its operation deals with the design of several variants of building insulation, and subsequent evaluation based on a comparison of operating costs of individual building variants. The theoretical part deals with the history of thermal insulation of buildings, there are types of thermal insulation materials and variants of energy-efficient houses. Then the normative requirements, energy intensity of buildings and methods of thermal insulation of individual building structures are solved. Subsequently, the methods of economic evaluation of the investment and the method of compiling the general budget are addressed. The practical part contains a description of the construction and the proposed variants of insulation, including the calculation of costs, evaluation of the payback period of the investment and evaluation of the proposed variants.
