Can Generative Ai Make Farming Decisions? Current Status And Future Pathways: A Case Study In Row Crop Production With Chatgpt, Nipuna Chamara, Yufeng Ge, Joe Luck, Yu Pan, Saleh Taghvaeian, Cory Walters, Christopher Proctor, Daran Rudnick, Daren Redfearn

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The agricultural decision-making process is experience-based, knowledge-dependent, time-sensitive, complex, and driven by historical data. Planting, fertilization, irrigation, and chemigation are key categories in farm decision-making, and currently there is no one-shot decision-support tool that covers all these activities. Generative Artificial Intelligence (AI) models are more advanced than traditional machine learning and deep learning models. These models have been trained on vast amounts of data from the internet, allowing them to accept unstructured data in various forms and generate human-like text, solutions to problems, and scenario predictions. Given this capability, we became interested in exploring the potential of generative AI in …

Assessment Of Super Absorbent Polymer In Soybean Cultivation Under Variable Irrigation Conditions In Nebraska, Ankit Chandra, Abia Katimbo, Ronaldo Marchezan, Martha Nabaggala

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Water limitation is a primary constraint to soybean productivity in both irrigated and rainfed systems. Soil-applied superabsorbent polymers (SAPs) have been proposed as a strategy to buffer crops against episodic drought stress; however, their physiological and agronomic performance under varying irrigation regimes remains insufficiently quantified. Here, we evaluate three biodegradable polymer formulations: broader granules (BB), original granules (OG), and powder (PWR) applied at low (17.7 lb/ac) and high (120 lb/ac) rates under full (100% ET), reduced (50% ET), and no irrigation conditions in western Nebraska. Polymer application had negligible effects under full irrigation, with yields comparable to untreated controls. Under …

Perceived Barriers To Integrated Crop–Livestock Systems: Evidence From A Nebraska Producer Survey, Omid Tarashtwal

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Integrated crop-livestock systems offer agronomic, economic, and environmental benefits, yet reintegration has been slow across the Northern Great Plains despite sustained interest. Existing research has documented barriers to transition conceptually, but quantitative evidence on which barriers producers perceive as most important and which producer and operation characteristics are associated with stronger barrier perceptions remains limited. This thesis addresses that gap using data from the 2023 Nebraska Agriculture Operator Survey.

The analysis focuses on 241 Nebraska producers, including 179 crop-only and 62 livestock-only operations. Seven models are estimated, combining ordered logit estimation for single-item barriers with linear regression for averaged barrier …

The aim of this study was to explore the progression of gardens parallel to Maslow’s hierarchy of needs. Additionally, the study aimed to determine whether gardens help fulfill those needs and, in doing so, influence human morality. To examine these possibilities, the researcher conducted a literature review of historical and contemporary accounts of gardening and its effects on physical and psychological well-being, analyzing these findings through the lens of Maslow’s framework. Additionally, crime rate data were compared across several …

Impact Of Community Gardening On Neighborhood Crime Rates: Research Proposal, Abby J. Cutsinger

ATU Scholars Symposium

Gardening has been a part of human existence from the beginning of time, but people have become distanced from gardening as civilization has grown and urbanized. As this distance has grown, so has the disconnect between people and the basic needs which shape their views of themselves and of society. It is possible that, in the drift away from gardening as communities, humans have become less moral.

The purpose of this study is to determine if community gardening lowers violent crime rates.

This relationship will be gauged by answering the following questions:

• Which type of community gardening benefits community relationships …

The first focus of this work considers improvements to nitrogen fertilization using small, autonomous vehicles. An agronomy experiment in corn assessed the effects of gradually applying nitrogen …

Modeling Wild Rice Bed Health: A Dual Metric Approach For Bed Strength And Invasive Impact, Seth Sisneros-Martinez

Journal of Earth and Life Science

Wild rice (mannoomin; Zizania palustris) is an aquatic grain that grows in slow-moving rivers and shallow bays throughout northern Minnesota. In Headquarters Bay on Leech Lake, wild rice has served as a cultural staple for Indigenous communities for centuries. However, its population has declined in recent years due to multiple environmental issues. One potential contributor is Eurasian watermilfoil (Myriophyllum spicatum; EWM), an invasive species that forms dense mats capable of outcompeting native aquatic vegetation, including wild rice. EWM was first recorded on the southern shoreline of Leech Lake in 2005 and has since become widespread. This study …
