On the Profitability of UAS-Based NDVI Imagery for Variable Rate Nitrogen Prescriptions in Corn and Wheat in North Dakota
(North Dakota State University, 2018)
This study examines the grower’s decision to invest in precision agriculture technologies especially in-season variable rate nitrogen applications based on NDVI data collected from UAVs. NDVI, yield, soil, and other field ...
Estimating the Economic Benefits of Automatic Section Control in the North Dakota Prairie Pothole Region
(North Dakota State University, 2018)
The impact of Automatic Section Control (ASC) as a tool of Precision Agricultural Technology as considered in the more efficient application of inputs to produce the four major crops, corn, soybean, HRSW, and canola in the ...
Economic Efficiency of Occupational Health and Safety Investments at Agricultural Cooperatives
(North Dakota State University, 2018)
Industries related to agricultural cooperatives record some of the highest injury rates in the U.S. Therefore, agricultural cooperatives are highly motivated to invest in occupational health and safety (OHS). This thesis ...
Robust Capital Asset Pricing Model Estimation through Cross-Validation
(North Dakota State University, 2018)
Limitations of Capital Asset Pricing Model (CAPM) continue to present inconsistent empirical results despite its rm mathematical foundations provided in recent studies. In this thesis, we examine how estimation errors of ...
Bidding Competition and Supply Chain Risk in Soybean Exports
(North Dakota State University, 2018)
Commodity trading at both domestic and international levels involves many sources of supply chain risk and uncertainty. Risk management techniques are utilized by industry participants; however, there are unknown risks ...
Snowmelt Water Infiltration into Frozen Soil in Red River of the North Basin
(North Dakota State University, 2018)
Infiltration into frozen soils is an important process in the hydrological cycle. Though infiltration occurs at the soil surface, it is affected by many factors, e.g. soil water content, temperature, and hydraulic conductivity. ...
Quality Evaluation of Coated Extra-Large Hulled Sunflower (Helianthus Annuus) Kernels for Precision Planting
(North Dakota State University, 2018)
Domestic and export demand for extra-large (XL) in-shell confectionary sunflower seeds (Helianthus Annuus) growing; however, a significant proportion of the hybrid seed for planting goes to the snack food market because ...
Sugarbeet Model Development for Soil and Water Quality Assessment
(North Dakota State University, 2018)
Sugarbeet (Beta vulgaris) is considered as one of the most viable alternatives to corn for biofuel production as it may be qualified as “advanced” biofuel feedstocks under the ‘EISA 2007’. Production of deep rooted sugarbeet ...
Developing a New Powered Seed Delivery System with Constant Seed Release Speed Using Two Confronting Belts
(North Dakota State University, 2018)
Seed delivery devices are aimed to carry seeds down to open furrow that might affect uniformity of plant stand and spacing. The objective of this study was to develop and evaluate a new seed delivery system utilizing a ...
Identification of Weed Species and Glyphosate-Resistant Weeds Using High Resolution UAS Images
(North Dakota State University, 2018)
Adoption of a Site-Specific Weed Management System (SSWMS) can contribute to sustainable agriculture. Weed mapping is a crucial step in SSWMS, leads to saving herbicides and protecting environment by preventing repeated ...
