1	The Integration of sUAS into a Diverse Agricultural Operation Newsum, Andrew January 1900 (has links) Master of Science / Department of Agronomy / Antonio R. Asebedo / Current population trends project that current agricultural production will need to increase by 110% by the year 2050 to support the growing worldwide population. Many agriculturalists are looking at precision agriculture technology to help achieve this production increase. One technology that is being heavily researched is the integration of small unmanned aerial systems (sUAS) and their sensors into the agricultural sector. Much research has already been conducted in the agronomic sector utilizing sUAS. However, relatively few advancements involving sUAS have been made in the animal science industry. This thesis focuses on how sUAS can be incorporated into a diverse cropping and livestock operation. Chapter 1 - Evaluating Current Capabilities of sUAS and sUAS Mounted Sensors in Diverse Agricultural Operation: A Literature Review, focuses on the current capabilities of sUAS and explains how they are incorporated into cropping systems and livestock production. Chapter 2 - Wheat Variety Interaction on Multispectral Based Vegetative Indices, focuses on wheat variety interaction with yield, grain protein content, NDVI, NDRE and CCCI. Ten wheat varieties were tested in large plot studies; yield, protein and multispectral data were collected for Feekes 4, 7, 10 and 10.5. Wheat variety was statically significant across all vegetative indices, protein and yield during less than favorable growing conditions. Chapter 3 - Estimating Cattle Rectal Temperature Using Thermography, focuses on determining the ideal location for thermographic readings to be taken to predict rectal temperature of beef cattle. To establish if sUAS-based thermography could be utilized for cattle rectal temperature estimation, 35 crossbreed steers were selected and thermographic readings and rectal temperature data were collected and analyzed for correlation. This study found stronger relation in the animal’s eye than other facial features. NDVI NDRE CCCI UAS Thermography
2	Uplatnění vybraných forem zinku při mimokořenové výživě kukuřice Pajl, Jaroslav January 2019 (has links) This thesis deals with the influence of foliar application of selected forms of zinc on the yield and quality of corn grain (Zea mays L.). The issue was dealt with in the form of a small-plot vegetation experiment on the landfill site in Žabčice. Zinc was applied in the 6-8 leaf phase in three forms of ZnO, ZnSO4 and Zn-EDTA at doses of 100, 250 and 500 g.ha-1 in each of them. A zinc-free variant was used as a control. In the course of vegetation (14 days after fertilizer application (20 June 2018)) and after harvesting, an inorganic analysis of the plants (Zn content) was carried out, NDVI and NDRE index were determined during vegetation. After harvest, the yield, starch content and weight of a thousand seeds were determined. Zinc fertilization proved to be (p≤0.05) affected by the zinc content during vegetation, but had no effect on NDVI and NDRE index. Grain yield was positively influenced, although no proven zinc effect was demonstrated. WTS and starch content in the grain were neither demonstrably affected nor significantly different from control. Zinc content in the grain was not significantly affected, but zinc fertilization was positive.
3	An Analysis of Grain Corn Nutritional Supplements and Relative Maturity in Mississippi Whittenton, Joseph Bryan 04 May 2018 (has links) A review of available corn relative maturity groups in Mississippi shows a limited range of maturity groups in use. Research focusing on expanding the range of maturity groups was conducted in MS in 2015 and 2016. Along with expanded maturity groups, treatments of fertilizer (10-34-0), foliar zinc, and a plant hormone blend were studied to shorten the growing season. Four site years in MS were studied to determine optimal plant maturity group and treatment for length of season. The results showed decreased yield of 0.09-0.15 Mg ha-1 (1.5-2.3 bu ac-1) for each day of decreasing relative maturity in three of four site years. The addition of starter fertilizer increased vegetative growth stage, plant height V5 and V7, SPAD values at V5, and significantly decreases days to tassel and silking reproductive growth stages but did not affect yield.
