Agricultural and Environmental Sciences Faculty Research
Efficient nitrogen (N) management is essential for sustaining crop productivity while minimizing environmental impacts associated with excessive fertilizer use. Variable-rate application (VRA) offers a precision-based approach to matching N inputs with crop demand, yet winter wheat responses to reduced N rates are still underexplored. This study evaluated winter wheat (Triticum aestivum L.) performance under variable and uniform N application strategies using canopy greenness (NDVI), grain yield, plant N content, nitrogen use efficiency (NUE), and fertilizer costs as indicators. Reduced N treatments (40% and 60% VRA rates) were compared with a uniform (100%) application. Canopy greenness increased across all treatments over …

Cotton Response To Tillage Systems And Irrigation: Interactions With Seeding Rate And Soil Textural Zones, Jennifer Hinojosa
Student Theses and Dissertations
Arkansas cotton (Gossypium hirsutum L.) producers have made progress in sustainable production over the past twenty years with expanded adoption of soil and water conservation practices, including reduced tillage and use of winter cover crops. Producers have been uncertain about the need to modify other practices as they adopt conservation tillage systems, particularly the costly decision on whether to increase cotton seeding rates when they plant into stale seedbeds with high residue from terminated cover crops. To address this question, an on-farm experiment in northeast Arkansas was conducted to evaluate cotton performance with modified cotton seeding rates in rainfed or …

Sustainability Implications Of Agricultural Practices In The Arkansas Delta: A Field To Market Approach, Melissa Adelle Palumbo
Student Theses and Dissertations
The Field-to-Market Fieldprint Calculator is a software tool designed to estimate and compare relative sustainability of differing agricultural practices. This observational research compared conservation techniques to conventional practices in rice and cotton on three separate farms in Northeast Arkansas. Considering management and site conditions, the Fieldprint Calculator was used to compare sustainability metrics to standards at various spatial scales in a spidergraph report. Eight metrics were analyzed to produce reports, including greenhouse gas emissions, water quality and quantity, land and energy use, soil carbon and conservation, and biodiversity. Results showed no significant change in yield between the different production methods, …

Cost Effects Of Adding Poultry To Organic Vegetable Production Systems In California, Iowa, And Kentucky, Kwanele Magwaba, Alejandro Plastina, Ajay Nair, Maurice Pitesky, David J. Gonthier, Anne Carey, Faye Duan, Viktor Halmos
Journal of Applied Farm Economics
This study evaluates the economic viability of integrating poultry into organic vegetable crop rotations over three years in Kentucky and Iowa and two years in California. Given the growing global demand for food and heightened environmental awareness, understanding the financial implications of such integrated systems is crucial. Our comprehensive experiment compared integrated poultry-vegetable rotations with vegetable-only systems, assessing costs, revenues, and key factors influencing profitability. While integrating poultry reduced vegetable production costs by up to 10% in some cases, overall system costs increased due to high poultry expenses. Break-even poultry prices averaged $8/lb for low-density systems and $7 for high-density …

An Analysis Of Cover Crop Adoption In Southeastern Row Crop Systems: Benefits, Challenges, And Policy Implications, Madison H. Mccay, Yangxuan Liu, Alejandro Plastina, Guy A. Hancock, Amanda R. Smith
Journal of Applied Farm Economics
Cover crops, utilized by producers to provide seasonal soil cover between cash or forage crop cycles, play a significant role in diversifying crop rotations and enhancing environmental sustainability. This research aims to assess the economic impact and farmer perceptions of cover crop adoption in the southeastern United States, particularly in Georgia, Alabama, and Florida. Producers show interest in adopting cover crops with increasing awareness of their benefits, such as improved soil health, water quality, weed suppression, and reduced soil erosion. Despite these advantages, adoption rates are hindered by economic challenges. A survey conducted from January to March 2021 gathered data …

Are Returns From Commercial Farming Heterogeneous? Case Of Wheat Growers In North India, Saroj Verma, Kirtti Ranjan Paltasingh, Phanindra Goyari
Journal of Applied Farm Economics
Contract farming (CF), generally a commercial farming system, is widely perceived as a welfare enhancement strategy in rural areas where agriculture is the major source of livelihood. However, those welfare implications have not been adequately explored in Indian agriculture. So, this study examines the returns to CF and the heterogeneity in their returns across various groups of wheat growers in Haryana, a leading agrarian state in India. Using an endogenous switching regression model on cross-sectional data of 754 farm households, the study found that CF adopters would lose 27% of their gross margins and 11% of their crop output if …

Long-Term Changes In Relative Humidity And Soil Wetness: Implications On Agriculture And Environmental Sustainability In Western Himalaya, Ashwani Ashwani, Pankaj Kumar
Journal of Environmental Science and Sustainable Development
Long-term climate changes in humidity and soil wetness in the cold deserts of the Western Himalaya are still not well researched. Understanding the long-term trends of relative humidity (RH) and soil moisture is crucial in high-altitude, cold desert regions for effective agricultural management and environmental sustainability. The study was conducted in a part of the western Himalaya, which is an ecologically fragile zone with a highly sensitive agricultural region that is vulnerable to climatic variations. A comprehensive study was conducted to evaluate the spatiotemporal variability of RH and soil wetness by means four techniques: Mann-Kendall, Modified Mann-Kendall, Sen’s slope estimator, …

Agricultural and Environmental Sciences Faculty Research
Southern blight, a disease caused by the soil-borne fungus Sclerotium rolfsii (S. rolfsii), is favored by the hot and humid conditions of the southeastern United States, posing a significant challenge to hemp production in Tennessee. Black plastic mulch (BPM), commonly used for weed control, can exacerbate the disease. There is limited information on the effects of straw mulch (SM), known to moderate soil temperatures and moisture, or planting time in disease management. Field studies were conducted in 2022 and 2023 at Tennessee State University to evaluate the effects of planting time, mulch type, and biofungicide application on disease severity, weed …

In this fact sheet, we examine the drought management options available to cattle operations on two Native American reservations in Nevada, the Duck Valley and Pyramid Lake Indian reservations. Specifically, we discuss the results of a study that evaluated the economic outcomes of two common drought response strategies: herd reduction and supplemental hay purchases. We also provide recommendations for ranchers regarding optimal strategies, i.e., those which would maximize profits for two rancher types, differentiated by their willingness to accept risk (risk-neutral) or avoid it (risk-averse).

Watermelon is a water-intensive vegetable crop that is sensitive to drought and requires adequate nutrient supply for good yield and fruit quality. It is an important vegetable crop grown on 142,000 acres in the United States and 586 acres throughout Utah. Utah experienced its driest year on record in 2020 during a five-year drought (2019 to 2023). This affected local ecosystems, including the Great Salt Lake, which experienced record-low water levels. The drought also negatively affected the agricultural sector, including watermelon growers. Higher-than-average fertilizer prices in recent years have also threatened watermelon production. Growing awareness of agriculture's water use and …
